I purchased 5 Diamond Lager yeast pkg's a few weeks ago and one pkg was soft. Merchant replaced but I never checked the pkg they sent and just placed it in the fridge, wrong friggin yeast. My bad!!
I found 2 pkg's of Diamond in my keezer with a exp date of 10/21.
2 questions: 1- Is the yeast to far expired to be viable?
2- If I use it, do you think it will make much of an impact on yeast cell count?
17 gallon/64L batch @ 1.050 OG
Low end of the pitching rate is 1g/L
