Expired yeast was a dud

Sunday, November 23rd, 2008

I have only had one bad experience with expired yeast. It was White Labs Southern German Lager. I found out after I got home it was about 6 months out of date!  I made up a normal starter using a half pound of DME and 4 pints of water (half gallon), to get a gravity of ~1.045. I cooled it down and pitched the ‘expired’ yeast into a 1 gallon glass jar. It just sat there for a few days and hardly bubbled through the air lock but a few times. I ended up tossing the whole thing out. This has taught me to always check the expiration date on the yeast.
