Kegerators for Homebrew: Stop Bottling

Bottling is the part of homebrewing people quit over. Two hours of sanitising, filling and capping, then three weeks of waiting, to produce fifty vessels you have to wash again. A kegerator replaces all of it with one keg, one connection, and beer that is ready in two days.

The decision before the purchase decision

There are three routes to draft beer at home, and they cost wildly different amounts:

1. Kegs in a fridge you already own. Two Cornelius kegs, a CO2 tank, a regulator and a picnic tap runs a few hundred dollars. It is ugly and you open the door to pour. It works perfectly.
2. A conversion refrigerator. A fridge purpose-built to fit kegs with no freezer shelf in the way, which you fit with your own tower and taps.
3. A built kegerator. Cabinet, tower, taps, regulator and CO2 in one unit. Plug it in, connect a keg, pour.

Most people buying their first system should be honest about which of these they actually want. The fridge-in-the-garage route makes exactly the same beer.

The specifications that matter

Keg capacity, stated in Cornelius kegs. A “full size” kegerator usually takes one commercial half-barrel or two to three 5-gallon Corny kegs. If you homebrew, Corny capacity is the number you care about, and manufacturers do not always lead with it.

Tap count. One tap means one beer on at a time and a purge every time you switch. Two taps is the real quality-of-life upgrade, and the gap in price between single and double is usually smaller than the gap in daily satisfaction.

Temperature floor. Standard kegerators hold around 38°F, which is right for ales and lagers. If you want to cold-crash, lager, or serve at true cellar temperatures, check the stated low end rather than assuming.

CO2 tank placement. Inside the cabinet costs you keg room. Outside needs a pass-through. Neither is wrong; it determines whether a “two keg” cabinet really holds two kegs plus gas.

The units

What else you are buying

The cabinet is not the whole cost. Plan on:

• Cornelius kegs, used or new, at roughly $60–120 each. You want at least two so one can condition while the other pours.
• Ball-lock disconnects and line if the unit ships with a commercial keg coupler, which most do.
• CO2 tank and fill. A 5 lb tank carbonates and serves several batches per fill.
• A decent regulator. Dual-gauge so you can see tank pressure and serving pressure separately.

Balance your lines or you will pour foam

The single most common complaint about a new kegerator is foam, and it is almost never the kegerator’s fault. Beer line has to be long enough that its resistance matches the serving pressure. Too short and pressure dumps at the faucet, breaking carbonation out of solution as foam. For typical serving pressures, five to ten feet of 3/16″ line is the usual answer. The line that ships in the box is often shorter than that.

How these picks were made

We have not installed and run these units ourselves. Picks are based on published specifications, Corny keg capacity, tap configuration, temperature range, whether the manufacturer supports the product with parts, and the long-running consensus among homebrewers about which of these last. Prices come from Amazon and refresh nightly; large appliances go in and out of stock constantly, so confirm on the product page before committing.
