I had a valve get stuck open while harvesting my yeast and ended up losing most of my healthy yeast from the conical. I'm doing a 2 bbl test batch next week and wanted roughly 2500 ml of 50% solids for my pitch and only ended up with about 500 ml (the rest went down the drain - bummer!). I'd like to do some propogation over the next week to get up to my pitching rate. I've never propogated like this before and from what I read up to a 10 fold increase is safe and I'm below that number which is good. Does anyone have any recommendations on the best process to do a 5 fold increase in about a week?
