Ok...Wyeast Czech Pils, packed Nov., 2019.
Smacked it yesterday afternoon to make a starter. After 5 hours, almost zero swelling of the packet.
I went ahead and boiled some light DME (1/2 C in 1300 ml of water). Cooled it, then pitched the yeast.
A foil wrap is on the glass jug. We have shaken it vigorously at times during the last 16 hours. For the first 10 hours, no signs of life. So...we moved the jug into a warmer room (74F) thinking this may help.
At this time there is no typical fragrance of CO2, but it does have a nice and pleasant odor. But no signs of life. The yeast looks like it wants to flocculate out, so we keep shaking it up.
Do we dare use this yeast on Sunday when we do our triple decoc Czech Pils?
Making a trip this afternoon to buy some Saflager W34/70...just in case.
