I will be brewing a Wee-Heavy this weekend. I usually create my own starters, but wanted to jump start this high gravity brew. My local brewpub brewer is going to give me the slurry from one of his fermenters. If I bring in a quart mason jar, he said he will fill it up. My question is, how much (i.e. 1 quart) yeast slurry is too much in a 5 gallon batch?
