Kegerator Robots

Wednesday, July 13th, 2011

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.

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 @ Yelp.com 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: http://www.youtube.com/watch?v=2tXmGYk_A_c 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: http://www.youtube.com/watch?v=LCIGIe2T4j0 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.

Kegerator Modifications: Splitting CO2 Lines

Monday, February 8th, 2010

One of the great benefits of owning a kegerator is tinkering with and modifying it.  One of the most popular modifications is to add an additional tap or two.  To modify your kegerator to dispense additional beers, you will need to split your CO2 lines.  You will probably want more than one tap on hand, so your kegerator can dispense from sanke kegs, soda or Cornelius kegs, or whatever keg may appear at your doorstep.  Splitting your CO2 lines can be as simple as a t-joint or as complicated as a multi-tap regulator for dispensing different beers at different pressures.  We will look here at the kits and equipment currently available on the market and processes for modifying you kegerator for dispensing any kind of beer from commercial to home and craft brew.

Co2 Splitter

For adding a quick extra beer tap onto your kegerator, a stainless steel or plastic t- or cross joint will do the job of splitting the CO2 to the different kegs – but gas leakage may occur if your keg tap isn’t maintained properly.  This is the most inexpensive way of splitting your CO2 line, and all you will need is the appropriate taps for the beer you want to dispense, surgical tubing, hose clamps, and of course the kegs of beer.  Adding an inline valve will even make it so that you can minimize gas wastage when changing kegs.  The T-splitter will cost you less than $5 and the inline valve probably less, and you can find for these items online or at your local hardware store in the plumbing section.  Aquarium supply stores may also have the fittings.  You will still need beer taps – more on that later

A more refined approach to splitting CO2 lines is the use of a gas distributor.  These units have one gas in and multiple gas outs to facilitate multi tap kegerator modifications.  The gas distributor has valves for each of the line-outs, and you can use a gas distributor to split your gas out in multiple directions.  Gas distributors are available in a number of configurations.  Two way gas distributors cost roughly $40, while the larger multi tap distributors with 6-8 line-outs can cost $120 or more.

For a draft beer system that requires dedicated individual pressures for different beers, a secondary regulator panel or a dual body CO2 regulator is necessary.  This is very advanced stuff most people need not go into this much detail, but these units will cost upwards of $150 just for the regulator panel, the price depending on how many regulators you need, or $120 and up for a dual body CO2 regulator.  If you want to force carbonate your beer while dispensing beer from the same unit, a secondary regulator panel or dual body CO2 regulator may be the modification you want to make to your kegerator.

One factor to keep in mind when splitting your kegerator’s CO2 line is that your operating pressure will decrease depending on the length of tubing you use.  When long lengths of tubing are used, the tubing expands and makes it difficult to keep the CO2 pressure at a constant rate.  The same also goes for beer lines.  If you cannot avoid having a long-draw system, you will need to use certain materials for the majority of the draw in order to ensure optimum beer quality and cleanliness.  You should strive to have no longer than six feet of regular surgical tubing from CO2 canister to keg, or 12 feet of beer lines all together from between keg and faucet.

Although there are some exceptions, long-draw systems still push beer from the keg via CO2.  The standard flexible surgical tubing is used, but coupled with a special “barrier tubing” soon after leaving the keg.  Barrier tubing is thicker than regular surgical tubing and has a mesh cover, which keeps the vinyl tubing from expanding and causing CO2 pressure irregularities.  With the use of a tubing flare tool, you can create your own stainless steel tubing for your beer lines as well, which are by far the most durable and cleanest options, although they are harder to build and modify.

What's so Special About Kegerator Beer?

Monday, October 19th, 2009

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

Thursday, September 3rd, 2009
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.

Mini Kegerators

Tuesday, October 28th, 2008

When discussing mini kegerators, it is important to make the distinction between which type you are talking about. There is the kegerator that is made from a mini refrigerator, and then there is the mini kegerator gadget. The mini kegerator that is made from a mini fridge is a compact, but still largely immobile device that is usually home made, using half sized or even smaller fridges. The mini kegerator that is a gadget is a new appliance on the market. It is quite portable, and a good way to enjoy draft beer while on the go – that is what we are talking about here.

Mini Kegerators"Gadget" Mini kegerators are a new retail item that helps you to enjoy cold beer without the expense of owning a full-on kegerator. Mini kegerators are becoming a more and more affordable way to ensure that you have draft beer on the go. Most brands come with a variety of options, such as DC power, cleaning kits, and temperature control. Mini kegerators that dispense 5 liter mini kegs are made by Krups, Heineken, Avanti, EdgeStar, Vinotemp, and other companies as well, so there are a variety of models to choose from.

These gadgets are currently priced right around $200 – $300. For all practical purposes, the less expensive units do just as good a job as the more expensive ones. For example, the Avanti Mini-Pub Kegerator retails for about $230, and the Vinotemp Mini Keg Beer Dispenser retails for about $100 more – $330. The Avanti has the benefit of being more compact, and the Vinotemp has a better temperature regulator. So, unless you have really exacting temperature requirements for your beer, you might as well get the more inexpensive brand – it is more likely to fit in the trunk or boat, or whatever you are traveling in. General compact-ability is a feature of most mini kegerator gadgets – at least, compared to the mini fridge kegerator or a full-blown kegerator. For this reason, these compact mini kegerators have enjoyed popularity among the draft beer fan crowd.

One of the great advantages of the mini kegerator is that they come with AC and DC power supplies. This allows you to run the mini kegerator off of your car, RV, or boat battery, even solar systems can power these mini kegerators. This makes it easy to take a small amount of beer (standard mini kegs hold 5 liters) out for a picnic, boating, or car camping trip. Mini kegerators can also be easily installed into your RV or boat as a semi-permanent appliance.

New advances in refrigeration technology may see a whole revolution in the way we cool all manner of things, including beer. Researchers at Penn. State have made headway in electromagnetic cooling devices. These devices operate without the use of a compressor or of Freon, and, if commercially viable, will produce machines that are much more compact than the bulky fridges we are used to. On top of this, Ben and Jerry’s, the famous ice cream men, have developed a way to cool their dessert via sound waves. By using a machine that employs pressurized helium gas and ethyl alcohol as a cooling medium, they keep their ice creams at a delightfully cold level.

The increased popularity and availability of kegerators is likely to create an industry that is capable of harnessing these new technologies and putting them to good use. It seems clear that, with this latest invention of the mini kegerator, the kegerator industry is willing and capable of incorporating new, inventive ideas into its arsenal of products. In short, we are sure to see more and more interesting forms of kegerators in the coming years.

The new options that these mini kegerators provide give fans of draft beer an excellent opportunity to enjoy draft beer in a variety of settings. While in the past, draft beer fans have gone to great lengths to install kegerator systems in their R.V.s, now it as simple as shopping around for a convenient new appliance. Some day, we may see mini kegerators replacing coffee makers in the office (certain offices, anyways), or at least be seen side-by-side with them. As it is, we will see them on the beach, the mountain retreat campsite, at sea, and at the omnipresent tailgate party. Draft beer to-go has become a reality at last.

Keg Theft: Kegs Disappearing From Bars and Breweries

Tuesday, August 26th, 2008

Not an activity we at Kegerators.com encourage, stainless steel kegs are disappearing from behind bars and breweries to be sold for scrap metal or possibly for home brewing.

The trend comes as the stainless scrap price has more than doubled in the last five years, making an empty 18-pound keg worth more than $13, according to price data for steel scrap sold in Chicago.

Hawaii actually passed legislation making beer-keg theft a crime. They may not have needed the law since existing theft laws probably would have covered it. But just for good measure, they passed it anyway.

Pacific Business News reported back in May:

Hawaii beer wholesalers reported the theft of more than 350 beer kegs last year, up sharply from the 30 stolen in 2006. Nationwide, approximately 300,000 of the stainless steel containers are stolen annually.

"This is a huge problem," Tim Lyons, legislative liaison for Anheuser-Busch Cos., testified in favor of the law. "It has just escalated beyond any reasonable proportion."

"Metal keg theft is a growing problem because they can be redeemed for fast cash at scrap dealerships," added Lance Hastings, Western regional director for state government affairs for Miller Brewing Co.

Imported Beers Taste Better In a Can?

Friday, June 6th, 2008

One of the great joys of the golden age of microbrews in which we live is the availability of beers from around the world. In most major cities in the U.S., you can find nearly any kind of beer. Many brands are imported from Germany, France, the U.K., Belgium, Japan, even Africa. If you can’t find it imported, the chances are that you can find an American made version of it. I will list some of my favorite imports here.

It is hard to stomach, but let me be the first to say: Newcastle in a can is better. I have always disdained canned beers ever since I started home brewing. Glass preserves the flavor, I used to say. Well it turns out that the clear glass bottles that Newcastle comes in don’t preserve the flavor as much as the opaque aluminum can. This is entirely understandable: sunlight is well known as a degrader of hop character in beer. This is why most ales of Newcastle’s quality are served in brown bottles. When Newcastle is drunk form the can, however, I must say that the taste improves. I can sense the light hop character I never before had in the beer, and it just seems fresher. Well, at least now I know: it isn’t always the container, but more what they put in it!

Of Guinness, it is always heard: much better in Ireland. There are many potential reasons for this, and I do believe it to be true, but if you live in the states, what can you do? It makes sense that Guinness at the brewery is made the same, whether in Ireland or the United States. It is my belief that from every moment after the keg of Guinness leaves the brewery here in the states, or is hauled off of the boat, it is at risk. This is partly because the beer is extremely sensitive to temperature changes. If it is not kept cool throughout transportation, it will undergo changes. If the tap system at the bar has hoses that are the wrong length, the carbonation will change. And the most obvious difference is that seemingly 99% of barkeeps in this country do not know how to properly pour a pint of Guinness! All the rest might as well be left up to chance, but it is high time that uninformed barkeeps in this country learned how to do it right. For those of you who have not been to Ireland, this is how you do it: First, pour roughly 2/3 of the pint full, at a slight angle of the cup. You then let this settle. It usually takes about 45 seconds for the initial pour to settle. Then you top it off and hand it to the patron. If you want to get fancy, you can make a leaf or such design in the foam on top, like they do with lattes. This method of pouring is the proper way, and allows the perfect degree of carbonation and proper head. If you are hazy on any of this, you should plan on going to Ireland to see how it’s really done. I recommend flying into Cork.

From Scotland, we have a true treat: in the ancient tradition of Heather Ale, Fraoch! This is a hop-less, or Gruit-style ale that is a little expensive, but well worth it! This craft ale is made in Scotland by Williams Brewing Company, and represents an elusive tradition of brewing that goes back 2,000+ years. The beer itself is a malty and rich amber with unusual bouquet. The beer is infused with both Heather and Sweet Gale, and imparts a lively inebriation to the imbiber. If you are a beer fan, you must drink this ale before you die! If you are a home brewer, try making some just to keep a 2,000 year old brewing tradition alive. The Fraoch website has some great reading materials on the history of heather ale viewable at: http://www.fraoch.com/history.htm

As delightful as it has been, I must now be off to dream further dreams of ales imported from the land of Morpheus. Until next time, drink it in good health!

Beers of the World

Saturday, May 31st, 2008

Beer has circled the globe more than a few times. One of the great treats a beer fan can enjoy is sampling the great variety of flavors that the beers of the world provide. In the U.S., beer fans have had the great pleasure of being served the beers of the world right here in our own country. Thanks to the rising popularity of fine ales, many of the beers traditional to Belgium, Germany, and the Nederlands are even being made by micro-breweries in the states. In the world of beer, there are still many as of yet unexplored brews from unexpected corners of the world. Here I will discuss a sampling of unique beers from 5 different countries: Africa (Palm beer), Brazil (Manioc), Tibet (Chang), and Scotland (Heather ale), all of which are described in Stephen Harrod Buhner’s book Sacred and Healing Herbal Beers.

Beer tends to be defined, in common parlance, as an alcoholic beverage made with hops, barley, yeast, and water. When talking about beers of the world, we must be ready to broaden our definition of the word beer to encompass that which is at hand. Grains of different types are used, from wheat to millet, rice, and even corn. In some place in the world, barley and hops are not available or simply do not grow there – and so, people make do with what they have.

For example, as we learn from Buhner in his book Sacred and Healing Herbal Beers, in Brazil, one native beer is known as Masato, or Manioc Beer. This beer has been made for approximately the last 4,000 years from a root called Manioc, which is also used to make tapioca. The Manioc root grows quickly, and attains a weight of up to 30 pounds within just a few months. It is used for food as well as to make the Masato. Traditionally, the root is chopped, boiled, and the starch to sugar conversion is catalyzed with human saliva. The women of the tribe chew the root pieces and then put them back in the boiling pot. Wild yeast is allowed into the wort to start the fermentation process. The Manioc plant is deeply ingrained into the cultures of the people who make it still, with it’s own mythology. You can read more about Manioc in Buhner’s book.

Another beer of the world made with unconventional ingredients (at least to the western world’s beer fan) is Palm beer. According to Buhner, palm beer is made with the unrefined sap from a variety of palm trees: date palms, coconut trees, moriche, sago, and palmyra being the most common. For many indigenous peoples throughout Africa, South America, and even India, Palm beer is an important part of life that transcends the physical world. Thus, it is often shared with the ancestors and used to help communicate with their spirits.

Getting back to more familiar ingredients, we shall look at Tibet. There, a brew called Chang is made mostly from Barley. Millet and buckwheat are used in some cases when barley is unavailable. What really makes this brew different from others, as we learn from Buhner, is the use of ginger-root-based yeast cakes for both the starch to sugar conversion and to start fermentation. Yeast cakes are made by crushing dried ginger root and mixing it with rice or barley flour. The mixture is then moistened and formed into cakes that are added to the boiled barley, rice, or millet that are being used to make the drink.

Heather Ale is an interesting beer of the western tradition that encompasses the herb heather as an admixture. The making of heather ale goes back to the culture of the indigenous Pictish tribes of the British Isles. In addition to numerous literary and folkloric assertations about the history of heather ale and mead, Buhner sites, in his book, an archeological dig on the Scottish Isle of Rhum. This dig discovered a pottery shard dating 2,000 years B.C. with “traces of a fermented beverage containing heather.” Heather ale has recently become commercially available in the U.S. as Fraolich ale, brewed in ???.

These five beers are just the tip of the iceberg. There are innumerable beers in the world, some still hidden away in remote corners, making the world of beer a very interesting place. New varieties of herbal beer are popping up among beer fans on the U.S. as well as inventive new micro-brews containing herbal admixtures, re-creations of ancient recipes, and brand new ideas in brewing. Keep your eyes open for the next invigorating (and inebriating) discoveries among the beers of the world.
