The Antarctic name of this uber-imperial stout originates from the amount of time it spent exposed to extreme cold. This beer began life as a 10% imperial stout 18 months ago. The beer was then cask aged for 16 months. After an intense 16 month, the final stages took a ground breaking approach by storing the beer at -20 degrees for three weeks to get it to 32%. As the beer got colder it was decanted periodically until only ice was left in the container, creating more intensity of flavors and a stronger concentration of alcohol for the next phase of freezing. The process was repeated until it reached 32% abv!!!
