General Info

Used home grown hops exclusively. Also used this brew as an excuse to get rid of several left over specialty grains. I'm about 99% sure that the 'Munich' is actually Munich.

I pitched this on the yeast bed of a previous batch (ccPale Ale #2 brewed two weeks ago) in a Sanke keg fermentor (15 gal). Fermentation started within 3-4 hours. By the next day, the fermentation had become so vigorous that the blow off bucket (6# liquid extract bucket) overflowed and wort/beer/yeast was flowing out of the fermentation fridge all over the garage floor. After cleaning it up replaced the blowoff container and placed it inside a 5 gallon Home Depot bucket to catch the blow off.

20110928 - Racked into secondary (2x glass carboys). Still has a little yeastiness, but the flavor and aroma is good. I was afraid the target FG (1.019) would be a little high, but it's currently at 1.020 and the sweetness balances nicely with the bitterness. Malt flavors come through and the flavor/bitterness of the fresh hops is evident.
