Old yeast

Bummer when you delay brewing until the ingredients get old. Liquid yeast cultures last about six months. According to the packaging, this is because in cold storage yeast slowly consumes its nutrient reserves. That also may be why it took some time to get the Saison started - older yeast.

I am heading to Bethlehem today - and planning a visit to the Keystone homebrewing shop - so I decided to check my remaining kits in case anything needs replacement. The Porter's yeast was manufactured in April! Good thing I am making the trip.
