The O’so Extreme Beer series is our take on very limited production wood aged fine beers. These ultra premium beers are released only when we feel they are ready, and not a minute sooner. Some of them age for months, some of them years. Some of these will never be made again, some of them might be. We are always working on new Extreme Beers.
