In April I made a nice Gose beer.. turned out great, but I could see improvement. I used Kolsch yeast (as suggested), and I thought.. that was expensive yeast.. let me save some (I have never done that before)... so I put a pint of the yeast trub in a tupperware, and put in the bottom of my fridge. .. so now I am thinking of making a Kolsch this weekend...and I am having second thoughts... should I reuse the yeast/trub?
Back in April I found a Youtube video about it and I decanted some of the yeast off the bottom of the fermentor... I am not sure of how much is trub and how much is yeast... how badly can I screw this up?
