Commercial Breathalyzers Help You Know Your Limit

Commercial Breathalyzers

Drinking and driving is always a bad combination. But it can be hard to tell, once you’ve started, when it is time to call a cab. Fortunately, commercially available breathalyzers are helping people to know when that limit has been reached. This is becoming more important as new ‘buzzed driving’ laws are being put forth in many states. Even one beer can land you a ticket now in some areas – all the more reason to drink at home with your kegerator home draft system!

We’ve come a long way in breathalyzer technology – according to wikipedia, the original roadside breath device used for alcohol testing used by the police was born in 1938, and was called the drunk-o-meter. Developed by Professor Harger, the drunk-o-meter took the suspected drunk’s breath into a balloon and pumped the breath through a chemical solution that changed color if there was alcohol in the breath, and a greater alcohol level was reflected by a more extreme color change.

Now, infrared, fuel cell, and semiconductor technologies are all different ways in which different breathalyzers operate. Of these, the semiconductor, also known as a silicon oxide sensor, is the least expensive and also the least accurate of the technologies. Semiconductor breathalyzers are prone to contamination and cross readings from chemicals other than alcohol that may be present in breath, and should be checked every six months to see if they are working properly. The 2010 BACtrack S75 Pro is one of the most accurate commercially available semiconductor breathalyzers. It can measure 0.000 percent to 0.400 percent BAC (Blood Alcohol Content), takes an air sample from over five seconds, and has a sensor accuracy of +/- 0.005 percent at 0.100 percent B.A.C. This unit costs $150 or less.

A more inexpensive version of semiconductor breathalyzer is BreathScan. This unit acts like disposable pocket version of the original Drunk-o-meter, using a colorimetric change. These units only cost a few dollars each, so they are a good choice for an inexpensive glove box item, for those rare situations where one is not sure about one’s B.A.C. Keep in mind that the criminal statutes concerning DUI or the new buzzed driving laws can vary between states and countries. BreathScan offers .04%, .05%, and .08% testers to compensate for these differences.

Platinum fuel cell breathalyzers work a bit better, usually requiring only yearly maintenance. One such breathalyzer is the BACtrack S80 Professional Fuel Cell Technology Breathalyzer. This unit has a test range of 0.00 percent to 0.50 percent BAC. It features a replaceable mouthpiece, so you can test your friends breath in a sanitary fashion, Xtend Fuel Cell Sensor technology for low power consumption, and a proprietary flow check that ensures a deep-lung air sample. Comes with six mouthpieces, 2 AA batteries and hard carrying case for around $150 to $200.

Another fuel cell unit is the BreathKey Breathalyzer, a digital key chain breath alcohol tester. This unit is lightweight – weighs less than an ounce, and is certified by the FDA to be +/- 0.010 percent at 0.080 percent BAC (blood alcohol content). This breathalyzer is not as accurate as the BACtrack Pro breathalyzer, but comes considerably cheaper, right around $$50 to $70, and is made in the USA!

Apart from BreathScan, you can see how your money is probably better spent on beer for your kegerator than a breathalyzer. Drink, don’t drive.

Kegerator Robots

Beer and robots are a great combination. As industrial America has disappeared, industrial art and hobbies have sprung up, utilizing the tools of the bygone industrial age. Now, we can count along with the many technological wonders of the modern age, beer launching robots, beer serving robots, automated home breweries, and even robot kegerators. A beer-launching robot has even been seen on the Late Show with David Letterman.

Kegerator Robot
Wired has a kegerator robot that serves beer

Robot building just goes better with beer. There are few hobbies that don’t go better with beer – granted, it may make hobby more dangerous, but with danger comes excitement. With excitement, danger, and beer, usually there is blood as well. It follows naturally that roboticists making robots in there spare time, drinking beer, would make such robots as the ‘killer’ robots pictured here. These robots, the Subjugator, Drunken Master, and Spiderbot, were made by Christian Ristow in association with RoboChrist Industries.

A decline in industrial manufacturing and industry in the United States has not meant a decline in inventiveness in the United States. This is especially true when it comes to beer and robots. Coming out of the home brewing revival in the 1970s was also a revival of the D.I.Y.(Do It Yourself) mindset. It took a while for D.I.Y. beer and D.I.Y. robots to meet up, but finally, we are there. Sadly, most beer LAUNCHING robots can still only fire commercially produced canned beer, and not home brew. However, these two hobbies come very close with robots such as Wired’s Beer Robot – a robot kegerator.

The engineers over @ took a keg and tap, an Arduino, an RFID reader, and an iPad and turned them into an amazing kegerator robot. The device not only tracks who’s been drinking but also tracks information about the beer as it’s poured, including the temperature and ratings of recently poured drinks (so you’ll know when the keg is on a roll). They even put together a bookmarklet to monitor and track the keg remotely.



It should be noted that the recent wave of D.I.Y. robot building has even taken the term “home brew” to describe many garage style hobbies. This term is often used to describe a hobby interest that comes from a technical or industrial field, but is made at home, such as home brew computers, home brew robots, and even engines. This is further proof of the connection between beer and robots.

One great moment of inspiration and promotion of home brew robotics was when the Late Show with David Letterman had a special guest: the Beer Launching Fridge. Also, the beer launching robot’s maker, John W. Cornwell, Duke University graduate. The Beer Launching Fridge that Mr. Cornwell invented launches beer up to 20 feet, and is remote controlled. In a blog post, Mr. Cornwall expressed the possibility that he may make his Beer Launching Fridge commercially available, and with improvements: the new design would allow a user to swivel the robotic armature with the remote, effectively aiming the launcher.

The phenomenon of beer and robots is not only confined to the garage and DIY inventors. Asahi has built a little robotic bartender that stores and pours beer. This invention can be seen at the following link: This robot seems to be built more for cuteness than efficiency, though. It takes about three and a half minutes for it to pour a beer, and it spills some, too.

One great take on the beer launcher is a mechanical unit which is foot pump operated. The ‘Ultimate Tailgating Machine’ holds 12 cans of beer and was the final group project for three student of a Design Class at U of I. See it in action at the following link: Brought to the world by Dan Larson, Justin Tobin, and Steve Walker.

As we can see, beer, kegerators and robotics are a great combination, with potential for great fun.

A New Year for Football and Kegerators

After a night spent celebrating on New Year’s Eve, for many New Year’s Day is a day to sleep late, deal with a hangover from the night before and then spend the day watching college football. For those that enjoy a few beers along with football viewing, or are planning to have a get-together to continue the celebration on this day off (whether to watch football or simply relax), tapping the kegerator is a part of this first day of the year.

Football and Kegerators

If you hosted a party the night before and didn’t own a kegerator, you may also be spending the day cleaning up lots of bottles and cans from the drinks imbibed by your guests during your New Year’s Eve festivities. And you also may be out of beer, which would mean you’d either have to watch football without being able to have a cold beer, or you’d have to run to the store to buy some more.

But if you own a kegerator, chances are that you still have enough beer left to enjoy a drink or two while watching the games, and you also don’t have a lot to clean up, other than maybe a few cups or mugs. So, all that’s left to do on this first day of the new year is to relax and to enjoy.

It is a tradition of many people to spend the day gathered with friends and family to watch football throughout the day and evening. New Year’s Day is one of the biggest football television viewing days of the year, and there is no lack of games to watch. As with many other football “big events”, drinking beer and eating good food are very much a part of the activities of the day. So, if you have a kegerator, hit the tap and pour a few cold ones for your football viewing buddies, take out the chicken wings and pizza, nachos, or whatever your game day food of choice is, and start cheering for your favorite team. The kegerator will supply the beer throughout the day – all you need to do is make sure that you don’t run out of food before the last game ends.

Even if you only have a mini kegerator, or if you got one as a Christmas present this year, New Year’s Day is the perfect time to time to take your new mini kegerator out of the box, pop in a mini keg of beer (that’s about 5 liters of fresh, cold beer to enjoy throughout the day with friends and family!), and enjoy!

Sure, you can get through the day without a kegerator and even without a beer, but one of the best ways to deal with a hangover, as well as to relax and enjoy the game, is to sit back on the couch with a cold beer or two, surrounded by good friends and fattening food. After all, there’s always tomorrow to start focusing on your more serious new year’s resolutions – today is a day for celebrating, relaxing, cheering on your favorite teams and enjoying yourself.

Hopworks Draft Beer Bike: Oregon Bike Culture

Hopworks Draft Beer Bike

Hopworks is a brewpub based in Portland, Oregon. Oregon is known for good beer and bikes, and Christian Ettinger, Owner & Brewmaster of Hopworks urban brewery, has combined those along with a determined commitment to sustainable brewing in all of his business endeavors with Hopworks. The Hopworks draft beer bike is a prime example of this commitment, a mobile, pedal-powered bar used to promote this business at beer festivals, street fairs, and other special events.

From the state of Oregon comes some of the most highly rated commercially available microbrews in the world. Rogue Brewery is well known as well as scores of smaller operations, such as Deschutes Brewery, Full Sail Brewing, and Captured! by Porches. Perhaps it has something to do with the great amount of fine hops that grow throughout the Cascadia region.

Oregon is also host to quite a few bicycle enthusiasts. Many clubs are operational in Oregon, including mutant bicycle clubs such as a chapter of the Black Label Bike Club, C.H.V.C.K.E.N. 666, and old-school club from Portland, Chunk 666 bike club. These bike clubs build all sorts of mutant bicycles such as tall bikes (made from two bike frames welded together vertically), flame-throwing bikes, and lawn-mower bikes. Here, you can see a mutant tricycle built by Dingo Dizmal, formerly of the Alberta Street Clown House (now gentrified out of existence in Portland, OR):

With such an inspiring beer and bike scene, it is no wonder that Hopworks’ sustainable choice for promoting their beer was a custom bicycle bar. Hopworks Urban Brewery incorporates many aspects of thoughtful, efficient sustainability in their operation, including composting and rain barrels for rain water catchment. According to the Hopworks website, “Hopworks is 100% renewably powered and “cradle to gate” carbon neutral.” Although CO2 (Carbon Dioxide) emissions may contribute to climate change (used to be called global warming, but you must use the current terminology), additional CO2 definitely helps the hops and barley grow. Still, the Hopworks commitment to an ecologically clean operation is admirable as they pump out roughly 6,000 gallons of beer each year.

The Hopworks Beer Bike is a modified cargo bike that holds two kegs, two custom taps, a flat bar, sound system, and a rack that can hold three large pizzas! The bike itself was built by Portland, Oregon based Metrofiets. Mertofiets specializes in the building of custom cargo bikes, based upon Danish and Dutch cargo bikes with aesthetics melded from 1940s through 1960s American Bicycle designs. Their work is artisan quality, and Metrofiets has made more than one brew serving cargo bike – they also made the mobile coffee bike for Trailhead coffee roasters.

The Hopworks Beer Bike has appeared at many festivals and beer events in Portland, and always gets a lot of attention wherever it goes. This can be attested to by this discovery channel link  And from Make Online:

What's so Special About Kegerator Beer?

Ah, to enjoy a cold draught beer after a long day of work or play – and in the comfort of your own home.  Kegerators can make any gathering more special, whether it is a night of music, movies, gaming, or football.  Finding the tight kegerator for your home can make all the difference, and they are essential appliances for the home bar, whether it be in the den or a speakeasy-style basement bar.  For home brewers, kegerators are the perfect choice for serving your kegged home brew.

Canned and bottled beers are great – but they run out so quickly.  They also take up a lot of space in the fridge.  This is why kegerators make such great additions to any beer fan’s home, whether you are a home brew hobbyist, a craft beer enthusiast, or just a fan of beer.  Draft beer just tastes better, especially at home.

Kegerator Beer

The best thing about having a kegerator around is when company comes over.  To be able to say to friends,

“Help yourself to as much beer as you want – the kegerator is right over there!”

That is a beautiful moment.  I remember my first night of kegerator drinking.  I believe it was Austin, TX micro brewery Live Oak’s Big Bark Amber Ale.  My host was generous, and the beer cold and tasty – thanks to his kegerator.  It certainly made that visit “just to say hi” much more special.

Buying a kegerator doesn’t have to be expensive, either.  Kegerator conversion kits can turn that old fridge that you don’t know what to do with into a useful appliance.  They are available for $50 to $250, depending on what design elements you wish to incorporate.  You can even put that top compartment freezer to use keeping pint glasses and mugs nice and frosty.

If you are looking for something pre-packaged, you can still get a mini kegerator for as little as $100.  These mini kegerators dispense store bought mini kegs of the five and six liter variety with optimum ease.  Some even dispense the beer with CO2, supplied via cartridge, to ensure that your mini keg beer keeps for up to 30 days.  But one party and that mini keg is toast, trust me.  If the beer has not been drank after 30 days, you are doin’ it wrong!

Most kegerators have the capacity to serve at least one 15 1/2  gallon keg of beer at time.  With pony kegs or soda kegs, and multi-taps, you can even have more than one beer on tap at one time.  Some kegerators come with four or more beer taps.  That’s better than a lot of bars! 

Kegerators are also highly customizable.  If you want more taps, you can always add them later.  Tap handles are another way to customize your kegerator.  Put tap handles of your favorite beers on your kegerator, or make custom ones out of a gear shifter or a My Little Pony.  I have even seen someone take a wooden wine barrel and use it to build a façade around their kegerator to make a most convincing and entertaining illusion that the beer flowed up right from a wooden keg.  You can equip your kegerator with a nitrogen system for smoother draughts or add a filtration system for clearer pints.  Spice up your kegerator with custom skins or beer decals.

Whether mini or full sized kegerator is for you, the benefits of having draft beer at home remain the same: make your home more hospitable, have better parties, and never be short of beer, even on Sunday.  A kegerator in your home bar is a definite plus, whether on game day or for a great birthday party.  All of this is what makes kegerator beer so special.

Kegerators and Lagering

Kegerators and Lagering

Lagering beer can be problematical for home brewers, if they are not properly equipped.  The key is that, for home brewing, kegs and lagering go hand in hand with the handy home bar invention called the kegerator.  A kegerator can do two things at once – act as a lagering closet and serve beer. If you want a little more control with your lagering temperature, you may opt for a lagering closet or separate fridge or freezer conversion.

The ideal lagering temperature for beer, according to white labs, manufacturers of specialty brewing yeasts, changes over the lagering period.  Ideally, the lagering process starts out at 51 to 53 degrees.  This temperature is maintained for the first week, and then the beer is allowed to warm to 62-64 degrees for four to six days.  After this, white labs recommends lowering the temperature five degrees per day until the ideal long-term lagering temperature of 31 to 32 degrees is achieved.  Then, lagering for six weeks at the lowest temperature takes place.

This is the most complicated lagering scenario I have heard of.  Most home brewers do not maintain such precise controls in any their brews, but it is clear that one would need to have a precise temperature controlled lagering closet in order to produce a lager of such exacting qualifications.  Keep in mind that the process of lagering was first developed by Bavarians keeping their beer in caves.

I would recommend a slightly more low-tech approach to lagering.  By utilizing your kegerator, you can lager your beer at roughly the same temperatures, as long as you are not serving beer at the same time (except at the final lagering stage, if you fudge the temp up to the regular serving temp of 38 degrees).  For the homemade conversion-style kegerators, there is plenty of room for an additional Cornelius keg, and sometimes a Sanke keg.

It is at this final stage that the keg comes into the picture.  This is the perfect time to transfer your lager beer into a keg for its final fermentation stage.  By lagering your beer in the keg for its final fermentation cycle, you can ensure that it will be a simple process to serve your beer.  After the fermentation is complete, simply tap the keg onto your beer line and serve.  No need to move the keg around and let it settle – although be sure to clean and sanitize your beer lines between each keg.

A custom temperature control can be installed into your kegerator or lagering closet if you do want to maintain such precise lagering controls as described by White Labs.  Johnson Controls produces what is probably the easiest to use temperature control unit.  The Johnson Controls unit plugs right into he wall and controls the power coming into your kegerator or freezer, turning of the power when the temperature reaches the right reading, and turning the power back on when the reading goes above the dial.

Whether you go low or high tech, lagering beer at home can be a challenge if you don’t have a kegerator or temperature controlled freezer / lagering closet.  It is not an impossible challenge, however, especially not for the home brewer who knows how to get things done.

Breweriana: Treasure Hunter's Guide to Nostalgic Collectibles from the World of Beer

Breweriana has been come to be known as the collectable detritus of brewing’s past. The term breweriana first appeared in the U.S. as the 1972 founding of the National Association of Breweriana Advertising. Most beer fans consider old beer signs, neon signs, advertising bills, old rusty beer cans, pint glasses, t-shirts, patches, or anything with a brewery’s logo on it to be breweriana. The collectiblility potential of breweriana is easy to see – some people have been able to make a great deal of money through the sale of breweriana antiques.

Breweriana is a popular field of collectables for a couple of reasons. Firstly, as with most collectables, is nostalgia. To determine the nostalgic value of an item you must look at how trivial items play through history. The item must also be authentic to be worth much. Knock off nostalgia items tend to break the spell of nostalgia eventually. As with other fields, in the area of breweriana, it is important to look at discontinued items.

Another reason why it may be profitable to trade in breweriana is that many bars look for these ancient items when assembling their décor. If you run across a big sign or neon from an antique dealer or scrapyard hustler, you might be able to turn a profit by inquiring at local pubs and the hipper dive bars. The antique décor motif is one used in curiosity shops, bars, and even big chain stores like the cracker barrel.

When looking at breweriana, it is a good idea to find out about the location of the brewery that first created the breweriana. Regionally, breweriana from closed down and defunct breweries is more valuable than it is nationally. This is because more people recognize the name brand of their once-local brewery or brewpub. It is a good bet that an old beer sign can fetch a better price in the state that it was originally displayed.

There are many folks that collect beer cans and bottles from the past. These items must be handled with care, as the beer contained within (if any) has often undergone a hideous transformation. Most collectors drill a small hole in the bottom of the can and drain the sometimes-noxious contents before setting the collectable on the shelf. Bottle caps can be pried off carefully and re-applied to achieve the same effect.

Keep a look out for older cans. Cone tops, crowntainers, and flattops are among the most valuable. Cone tops and crowntainers both have a cone like top, which was usually capped with what we cap bottle caps these days. Flattops had no tab and required a bottle opener to get at the beer inside. “Instructionals” is the term for flattops that have instructions for opening listed on the side of the can.

Some of these cans, the earliest from the Krueger Company, required their own can openers. Flattops had no tab and required a bottle opener to get at the beer inside. The "flattops" needed a regular can opener, the sharp lever-pry type. Some of these collectibles (the openers) are usually formed from a piece of steel rod which loops around and is about 5-6 inches long. Usually the beer can openers have a stamp from the beer manufacturer. One of the more popular pieces of breweriana among private collectors is the crown, or bottle cap. Bottle caps were initially manufactured in the 1890’s. Those that survived through prohibition are the hardest to find, and most of those are from defunct breweries.

Beer signs, or even posters, are another hot item, mostly because they are sought after by bars and pubs to add to their décor. Some older signs look like posters but have been printed on sheet metal. We can see reproductions of these items out on the market as well, such as the old Guinness mascot, the beer-swilling Toucan. The original designs are worth a lot, not so much for the reproductions.

When looking for breweriana, make sure you know what you are looking at. There are many books out on the subject now, such as Beer Signs for the Collector and the Beer Advertising Memorabilia series. A visit to or your local library will give you some insight on this field of antiques.

Breweriana: Collectible Pint Glasses

Collecting takes many forms, and in the world of beer collectibles, or breweriana, one of the most popular collectibles are the vessel by which beer is imbibed. From the early days of earthenware steins to crystal goblets, beer has been enjoyed in a variety of vessels. In recent times, the glass that most accurately symbolizes good beer is the pint glass, and many brew pubs and breweries have released their own logo-ed pint glasses, which are treasured collectibles for fans of their brand.

Pint Glasses

The number and variety of collectable items related to beer is staggering.  From beer signs dating back to prohibition days, to antique steins from Europe, to painted bar mirrors, to modern day pint glasses, breweriana is seen from coast to coast.  Of the many forms breweriana has taken, it is the pint glass which has now come to the fore of the modern collector’s shelf.

A look at the collector’s market for antique beer collectables will show you just how much beer vessels can fetch.  Some go for as little as $5, but the older items can fetch hundreds or even a thousand dollars!  Of course, you may not be around by the time your pint glasses are worth that much, but collecting is best when it is about enjoying what you have, not selling it!

These days, most commercial beer makers have produced pint glasses with their logo emblazoned upon them.  These are sold to the public at many breweries, and also to commercial bars, restaurants, and suppliers in the food and beverage industry.  The most collectable of these is the limited edition pint glass.  Usually minted in order to celebrate a special seasonal beer, these are sold at the brewery and at beer garden festivals as well. 

Commemorative pint glasses like these are great reminders of good times and good beer.  But not all commemorative pint glasses are produced for beer.  Many events are now making their own commemorative pint glasses as part of a lucrative merchandising strategy.  Events like Phoenix’s World Invitational Joust, Sports clubs, and even bands are producing pint glasses to commemorate shows, parties, and seasons.  In this way, pint glasses are beginning to move past the realm of breweriana into larger scopes of collectables. 

It is nice to have some different pint glasses around for social events as well.  A glass like the Phoenix’s World Invitational Joust commemorative pint glass can be a great conversation starter!  Glasses from local brewpubs can also remind people of good times they had there.  “Remember when…”

Often, a set of pint glasses will have a matching beer tap handle.  For those breweriana fans that own their own home draft beer system, these tap handles can add a nice touch to your serving.  There are many places on-line that sell different beer tap handles, and on ebay you can even find sets of matching pint glasses that come with the beer tap handle.

Collecting pint glasses is a common practice among home brewers and home bar owners.  Keeping an eye out for unique and interesting pint glasses can enhance your home bar experience and that of you guests – so keep an eye out for ‘em!

Extreme Kegerators

There’s a new trend taking place amongst kegerator builders that is taking some of their designs to the extreme. Bigger, faster, stronger is the American way and so why not apply that to the modern kegerator? Well here is a few of the extreme kegerators we have been seeing lately that are likely to spawn a whole new way of thinking when it comes to drinking draft beer from a kegerator.

Kegerator Cabinet

Garage Tool Cabinet Kegerators
If you were out shopping for a new tool cabinet for your garage you would expect to find features like durable chrome plating or rolling casters, but would a kegerator be an upgrade you would be interested in? Garage Fabricators from Central California thinks it should be. They’ve created the Diamond Plate Kegerator Cabinet that comes fully loaded including powdercoated steel plating and welded 6" phenolic casters. The kegerator cabinet is 23.5” deep x 47.5” wide x 64” tall and has the option of a Flatscreen TV mount. For only $1,678.57 you can call one of these kegerator cabinets your own.

Arcade Kegerator

Arcade Machine Kegerators
Whether its Pac-Man or Mario Brothers, imagine having access to fresh draft beer while playing your favorite arcade games. Well, two companies we’ve found seem to have the same idea. The Custom Bar Guys in Roanoke, VA have created THE GAMERATOR.
