Just brewed with Frementis US-05 yeast. Brewsmith asks yeast date but there is only what looks like an expiration date, 04-2014, on the package. The other numbers are 78539 114 1459. Am thinking these numbers are a mfg date code or Fermentis has a set shelf life, mfg date being back tracked from the exp date.
