I just brewed up a 5 gallon batch of Janet's Brown ale and had an OG of 1.065.
I thought I would try using the Smackpack Wyeast Pacman from Rogue that I got a couple months ago. I didn't realize it was actually really old. It was a limited release made available January though March of 2010 so it could actually be year old!
I did a 2 liter starter on a stirplate, and it fermented out like normal...though I will have to say that when I cold crashed it, there wasn't a ton of yeast on the bottom, and it looked nice an creamy white.
I've never pitched yeast this old...or I guess since I did a starter with it, this little. Any ideas of what I can expect? I usually pitch a really good amount of healthy yeast. I guess it isn't so much old yeast as it is a small amount?
