One Keg Multiple Avatars:

  1. For fermentation, you can attach an airlock/blow-off tube to the gas outlet.
  2. To make lagers: you can place them in a chest freezer, wine cooler or refrigerator and attach a temperature controller.
  3. For carbonation (beer or sparkling cider/wine): you can attach carbonation stones to PRV.
  4. One 5 gallon keg = 60-pint glass bottles. Saves you the hassle of cleaning, filling, and capping.
  5. For dispensing: you can attach it to your party tap, jockey box, or Keezer.

Premium new ball lock keg rated to 100-130psi working pressure (tested for 195psi pressure) and are made using a robotic orbital welding machine and super smooth welding marks making them easier to clean.
These Corny Beer kegs are also passivated and pickled giving them a matte finish, to ensure superior rust protection (SS304 steel used). Far superior than any second hand or economy kegs on the market.
Black rubber handles and base allows easier transportation and fewer scuffs on the floor.

Corny Keg Contains:

  1. Gas and liquid ball lock posts for easy attachment to your kegerators/keezer.
  2. PRV (pressure release valve) Lid for easy cleaning. It is wide enough that you can manually open and clean the base of the keg.
  3. Separate gas and liquid dip tubes. (unlike growlers and A-type commercial kegs) separate tubes make it easy to attach and maintain.
  4. Dual rubber handles make them stackable and helps in easy storage.
  5. Being thin and long, it is easier to do temperature control and make lagers or low-temperature brews.

Benefits as Fermenters:

  1. With an ability to withstand 120 PSI pressure, these kegs are ideal for pressure fermenting.
  2. Its tall boy design increases the surface area making the fermentation temperature uniform.
  3. Unlike Glass Carboy, they don’t shatter and make a mess.
  4. Unlike Glass Demijohns they have a wide neck that makes them easy to clean, replace, and repair.

4 Different Types of kegs:

  1. Commercial brewery kegs short fat kegs with A-type attachments
  2. Growler that is relatively difficult to clean (narrow mouth)
  3. Pin lock kegs
  4. Ball-lock kegs with 4 openings (gas, liquid, PRV Valve, PRV lid for filling/cleaning) – which Arishtam Sells

Please buy compatible attachments and fittings for your system. We also stock ball lock posts for those trying to migrate from pin-lock to ball lock mechanisms. Use keg connects for beer lines.

Please don’t use strong acids and chlorine bleach to clean the kegs. This damage the rubber and tight fittings needed to pressurize the cylinder.

Delivery mode:

Stainless steel fermenter kegs can be dispatched via Indian speed post only.

We do stock ball lock connects, replacement posts, and gaskets. However, you can get CO2, regulators, etc locally from the soda stream/fountain lemonade vendors.

FAQ (10)

Wooden wine barrels are a lot of commitment in terms of space, cost, and care for most homebrewers. Instead what we recommend is using a ball lock keg and oak chips. For more details refer to this guide.

While beer brewers add just 8gm of sugar per liter of beer, sparkling wines, cider, and champagne need 16 to 25gm of sugar to create that loud distinct pop sound when you uncork a fully pressurized bottle.

Note: Be careful to use only steel kegs or extra thick glass bottles. Normal glass bottles and water bottles are not meant to withstand this pressure and tend to burst.

Typically bottled home brew beer has a shelf life of 6 months. However, most home-brew beer is consumed within a week to a month of bottling or kegging. However, some people regularly store homebrew beer for up to 6 months successfully. Beyond this, the beer is still safe for consumption, just that it will not taste fresh. However, a couple of factors need to be taken into account to determine the shelf life.

  1. Storage temperature: Beer is like wine, higher the temperature the faster is the degradation in flavors.
  2. UV light: Even a couple of hours in direct sunlight can ruin a perfectly fresh beer
  3. Packaging: Microbrewery Growlers don’t last 2 days because the beer was oxidized during filling. If you see packaging in proper crown sealed glass bottles or stainless steel kegs, 6-12 months life is easy
  4. Oxidation: Once you open the bottle, drink within an hour.

Kombucha traditionally is made in a glass or porcelain fermenter. We would strongly recommend you to start in a similar mason jar or a pickle jar that is typically found in Indian kitchens. Tie it with a muslin cloth (or handkerchief) to prevent insects from dropping by.

As you scale your kombucha, we would recommend you to use either:

  1. Conical fermenter: This allows you to rapidly clean the sediment without disturbing the SCOBY. Hence, you can ferment faster and scale up your enterprise.
  2. Another option is to ferment in a Corny Keg. These are inexpensive and allow you to produce very good quality natural carbonation. You can sell and transport in the kegs as well. This allows you to scale up fast.

Cornelius keg (also known as a Corny or Corney or soda keg) is a beverage keg originally made by Cornelius. It is a stainless steel canister designed to withstand huge pressure (120psi 4 times what is there in your car tyre).

They are ideal to store, dispense, carbonate, and even transport sodas, beer, champagne, kombucha, and ginger ales. Its unique three mouth design makes it easy to clean and maintain kegs over many years. Also, its long slender design makes it easy to refrigerate and store in tight spaces like your chest freezer.

Kegs are easy to maintain. A standard 11/16 x 7/8 in. wrench is sufficient to remove the keg ball lock posts and dismantle the keg for cleaning or repairing. However, we will recommend you to buy 7 in 1 spanner. As it can help you with your beer lines and beer taps as well. It is ideal for all microbrewery purposes.

A corny keg has 3 inlets and a PRV (pressure release valve). To fill the keg, open the large oval lid to fill the liquid. Use the gas inlet to fill in CO2 and the liquid inlet to dispense.

Corny kegs, don’t have any markings. This makes it difficult to set up for the first time. To find out which side to connect with CO2 gas and which side connects to your beer lines, there are 3 ways.

1. Dip Tube

Open the keg and try to feel the inside of the keg posts. The liquid line will have a long dip tube going all the way to the base of the keg. The gas line will have a shorter inch and a half stainless steel tube (as shown in the picture)

2. Keg Post Construction

If you are unable to open the keg (because it is pressurized or filled), then look at the keg-post construction. The gas post is smoother while the liquid post has a ridge design. As shown in the picture.

3. Ball Lock Connect

Find the ball lock connect on which Gas is written (usually the white/grey in color) and connect it to the keg posts. If it fits then you are golden. However, this is the least reliable method as modern keg connects fits both ends. This is because some home brewers like to force carbonate their kegs by pumping CO2 from the beverage end instead of using the carbonation lid.

Typically I fit in 7-8 kegs in a chest freezer aka Amul ice-cream refrigerator. Just attach a thermostat and you are good to go. You can buy your keezer attachments here.

If you are unsure how many kegs you can fit in, cut out 8.5 inches circular discs (you can also use serving plates of 8.5-9 inches diameter). Place it inside the refrigerator to cover the area.

If you are trying to fit your corny homebrew keg in a fermentation chamber or mini-fridge, just make sure that you have knee-length height in your keg which is 25 inches for 19L and 14.25 inches for 9.5 Liters version (plus an additional inch or two for maneuvering)

Your beverage serving cans are made of aluminium. Kegs are made of SS304. Reasons are:

  1. This allows it to store highly acidic homebrew like cider, mead, and wine. (Even gose style beers and lambic beers).
  2. Also aluminium is a soft material prone to scratches, while stainless steel is tougher. This prevents contamination from hiding in the scratches and ruining your brew
  3. Aluminium cans are coated with a food-grade resin coating from inside to be able to withstand corrosion. This mechanism is good for disposable containers. However, kegs are supposed to be re-used. Hence checking the coating integrity every time you empty them is going to be tedious. So kegs and equipment used in the beverage industry are made from Stainless Steel and not Aluminium.

Bottle beer goes bad for three reasons:

  1. Exposure to sunlight: Beer is sold in brown bottles so that UV and sunlight is blocked. However, still some sunlight goes in the bottle. Sunlight reacts with hops and alcohol to create skunk beer. Corny beer kegs are made of opaque stainless steel. Hence there is no scope of UV or sunlight reacting with your beer. Hence UV skunks or bad beer does not happen in kegs.
  2. Oxidation: One of the reasons why bottled beer has an expiry date is because of micro-oxidation at the crown cap crimping. Over 6 months this steel joint on the glass bottles can become loose and oxidize the beer. Corny Keg and aluminum cans have a much tighter seam and hence no oxidation. Brewers worldwide have aged sparkling wine and beer in kegs for 2 years without any apparent oxidation.
  3. Heat Staling: Hoppy bears are prone to getting stale cardboard-like off-flavors when exposed to high temperatures for extended periods. The kegs are usually taken better care off. Unlike the glass bottles that often are transported and stored in the open and outside refrigerator. Hence chances of heat damaged beer in a keg is negligiable.

Essentially can beer tastes better than bottled beer. Keg beer tastes best.

Another problem with bottled beer is that once it loses its CO2, it goes flat. There is nothing much one can do to resurrect this beer. However, in a keg, one can always force carbonate and get the fizz back. Unless there is dissolved CO2 and pressure, one cannot pour the beer. So be assured your keg beer will always have foam.

  4. Mahesh Thiruppathi (verified owner)

    Order No 4940, Received Keg today. Slightly Disappointed because of minor dent on the side. Dent caused most probably on transport. No cause of major concern. Did a leak test with water, found the seals holding up. Need the disconnectors for putting keg in use. Disconnectors ordered thru other site , stuck because of covid disruption. Nice quality SS. Probably a 304, Carried out Magnetic test and found satisfactory. Overall a good product. Kuddos for the store manager Ankur.
