I have always pitched dry yeast in the past. I thought I would try liquid yeast for a change.
However, when my package came, the included cold pack was warm and the yeast packs were bloated. (It was a hot day) I did put them into the refrigerator immediately upon opening the box, and currently they are no longer bloated.
Do I need to worry about the yeast being bad?
I have Imperial Yeast A07 Flagship and Wyeast 1469 West Yorkshire Ale yeast.
Also, I read that Northern recommends using Fast Pitch Canned Wort, but they never seem to have it. How necessary is it?
