What Every Good Bartender Needs to Know About Guinness

Last updated 5 years ago

Since Guinness is one of the world’s most popular beers, a solid understanding of it can go a long way in boosting a bartender’s credibility. Here are some aspects of serving and drinking Guinness that every good bartender should know:

How to Pour It

The process of pouring a perfect Guinness starts by taking a Guinness-brand glass and holding it firmly at a 45-degree angle. With your finger on the harp, open the tap and let the beer flow in. Gradually straighten the glass as the beer level reaches your finger, and close the tap when it has filled up about three-quarters of the glass. Then you’ll need to let the beer sit for just a moment, to allow the nitrogen bubbles within the drink to form its signature creamy head, dark body, and milky swirl. As soon as the head has developed, slowly add just enough additional beer from the tap to bring the head to the rim. At this point, the beer is ready to serve.

How to Drink It

This is a nice tip to give Guinness novices at your bar. There is an art to drinking Guinness in a way that lets all the flavors shine, and it’s not too difficult to teach someone. Rather than dipping your head to look at the beer as you drink it, look straight ahead and bend your elbow at a horizontal angle as you bring the glass to your lips. Allow some of the foam to get on your lips as you take a drink, and you will be able to taste the creaminess of the cap as well as the smooth, dark body.
