I'm posting this because I'm amazed at the fact that I'm brewing with washed yeast that I washed on 7-8-11. It is now fermenting like crazy at 48-50*F. Below is a pic of the starter from last week. I was pretty anal about being aseptic and it seems like the yeast was fine and kept cold in a fridge the entire 19 months. I've gone over a year before, however not this long with washed yeast. Just ignore my ghetto stir plate, it works quite well though. Oh I forgot to add, it's WLP820 Oktoberfest lager yeast.
