General Info
This is a batch of Humptoberfest brewed to be blended with the prevous batch that did not attenuate enough. This one will be fermented with a HUGE starter of American Lager yeast (a very attenuative lager strain). After fermentation, it will be blended with 5 gallons of the previous batch.
Target FG for this batch: 1.010-1.012
Target FG for the blended batch: 1.013-1.014
