How To Tap A Keg of Beer The Correct Way

Whether you're a beer aficionado or just enjoy the occasional brew, knowing how to tap a keg is fun. With a few simple techniques, this process can be done by anyone in a few steps. And don't worry if you mess up - the only consequence is a shower of beer!

We'll walk through how to tap a keg of beer with a coupler, setup and instructions so that any beginner can do it like a pro.

Make Sure You're Using the Right Coupler 

Before tapping a keg make sure you have the right keg coupler to tap a keg. More than likely you will because the distributor supplies retailers with the right coupler for the keg they are pouring. If you are using a party pump coupler that will be provided by the distributor as well. Here's an overview from Micro Matic about different types of couplers

In this example, we will be using a D-system coupler. Which is the most common type of coupler in the United States. Here's a picture of some other styles of couplers and kegs below.

Be Sure the Keg is at a temperature of 38 degrees

Before you tap the keg you want to make sure your keg or beer is at the right temperature for dispensing. If the beer or keg is warm. When you tap the keg you will pour foamy beer. The ideal temp is 38 degrees. Typically it's nice to let a keg rest in a beer cooler for 24 hrs before tapping it. So that it's at temperature.

Make Sure Your C02 is Turned On Before You Tap The Keg

Before tapping  make sure that your C02 is turned on and working. Bleed the air inside of your jumper line by engaging the coupler in the air. This will push any air out of your beer line and make sure it's only c02 before you tap your keg. The last thing you want to do is push air into a keg of beer.  Depending on the type of beer system you have you will also be able to check the pressure and make sure it's set correctly, by bleeding c02 out of your coupler.

Tap Your Keg

  •  Make sure that your keg coupler handle is lifted all the way in the up position
  •  Look for notches on the keg of beer and beer coupler. Line these up and turn the keg coupler clockwise until the coupler stops turning.
  •  Pull back the lever and push down simultaneously until you feel and hear the coupler click and lock in place. 

 Here's a a little video I put together a while back going over the steps above. It's part of a video I made talking about the D-system coupler.

 If you haven't done those steps correctly you'll know because you will get sprayed with beer. Don't worry all you got to do is reverse that order, follow those instructions and try again.


Now you know how tap a keg. Following these steps closely will add to your experience and make sure that the keg of beer you tap. Will be ready to pour on temperature so you can enjoy a delicious adult beverage.
