What is the most aggressive yeast you've ever used? For me it would have to be the Nottingham yeast I pitched 2 days ago. I have never witnessed fermentation like this before. The beer was a 1.075 og. I have used so many other strains, liquid and dry but Damn, this stuff is great. On the downside i have easily lost 1/2 to 3/4 of a gallon through the blow off tube. One last question, how quick do you think this beer could finish up? I started two days ago and get married on the 26th of this month. Is it possible? I will force carb the day before.
