If you haven't had the chance to try cask beer on your own, you are missing out on one of the purest forms of beer you can drink. Having said that, it is one of the rarest forms of beer nowadays and can be very difficult to find.
So why don't we see more cask beer being brewed nowadays? We were able to catch up with Boulder Beer brewmaster and co-owner David Zuckerman and ask him this question.
"The reason you don’t see it is because it’s not convenient. It’s not convenient to do and it’s not convenient for the bartender to pour. That being said, I think it’s the most amazing way to consume a beer. I’m sure you know it goes back to days before electricity where that’s how you would move beer from the cellar up to the pub.
"It’s beer with nothing added and beer with nothing removed. So there’s no filtration, there’s no carbonation added. Everything that went on in the brew house and in fermentation is what you’re consuming. That’s the complete unaffected beer. I think it’s a beautiful form to drink beer," Zuckerman said.
He continued, "The reason you don’t see a lot of cask beer is there are so many choices in bars now, that it’s a challenge to get it to be able to rotate quickly enough to be fresh. It’s got maybe a four or five day shelf life. That’s not how beer is sold now.
"It’s put in a sealed keg; it’s pushed with CO2, so it’s a closed unit. It can last for a month or two, and cask beer just flies in the face of that, it comes delivered saying, ‘pour me fresh now, and then five days later I’m done.’ But that’s not how beer is thought of for the most part now," Zuckerman said.
Boulder Beer does have a small availability of cask beer on tap at their brewery in Boulder. Zuckerman talked their cask beer and some of what goes into it.
"We take a lot of pride in our cask beer and we do a traditional cask. There are some people who will take unfiltered beer and put it in the keg, and then pour it with a light blanket of gas, but we put our cask beer into firkins. We put guile in so there is a secondary fermentation in there. It’s the full proper process that gives you a product that is distinctly fresh cask conditioned-beer," Zuckerman said.
