Imperial Stout – All Grain


General Info

Brewing this beer for the future - 5 gallons is Izzy's and 5 is mine. This one will be fermented as usual, but will be aged in the club's oak barrel starting in April, 2009.


Final brew session of 2008. The thirty-sixth, which equals ~180 gallons of beer! Missed OG by .037 - don't know where it went wrong, but it's still a helluva big beer (December 23, 2008).

Aged in an oak barrel for 13 months. Received ~ 4 gallons of black goodness. Will bottle all of it and seal some with wax. OG and FG numbers reflect the blend and not my brew session (April 17, 2010).
