O'so lambic Extreme Beer fermenting.O’so Extreme Beers

The O’so Extreme Beers are beers that we cultivate and grow on our over 400 cask barrel farm.  These premium beers are released only when we feel they are ready, and not a minute sooner.  Some are sour. Some are clean. Some are Imperial-style, high abv sippers. Some are fruited, face blistering sours.  Some are aged for months.  Some are aged for years.  Most of these will never be made again, but then again, some of them might be.  The only thing that you can count on with our Extreme Beers is that we pour our hearts and souls into each and everyone one, and we know you will love them!
