OK, so long story kind of short. I brewed Sunday night. I pitched two bags of 6 month old London Ale Wyeast. After four days (Thursday night) there was no change in gravity, no change in temp and no krausen. So I sprinkled a pack of Windsor on top, WAA-LAA activity ever since. My question is; are my flavors going to be all jacked up due to using two different kinds of yeast...and is it even work washing this yeast and keeping?
