I just reused yeast for the first time and I used tips from this site. I pulled the beer off of the cake and bottled it, returned the airlock to the fermenter for 1-2 days until I was ready to brew the next batch. I brewed up the wort, cooled it and when I was ready to pitch I poured 2 cups of water onto the yeast cake and swirled it around until it was all in solution. I poured half of that into the new wort and aerated. I poured the rest down the drain. Fermenting was terrific for this batch.
2 questions that I have for re-using yeast are:
1. Can you store yeast longer term (like you do with a White Labs vial) for future batchs? If so, how do you store it?
2. Have you used yeast cakes from types of yeast that you wouldn't normally use for the style of beer that you are brewing up? I like the idea of re-using yeast and I can see myself mixing yeast and styles when re-using yeast cakes. When I buy yeast vials I am sure to match styles as I am sure most of us here do.
