I thought I heard of long storage yeast. I can’t find any. I have the 2 year stuff and know frozen it lasts longer. I also do the sourdough thing. A recent experience with brick like cinnamon rolls, made with 12 year old yeast that I thought I had proofed and used 3 times the amount called for....... you know the rest. I just thought it would be nice to have “regular” yeast for special occasions. I found recipes for making yeast but figure my sourdough is just easier. And nothing compares to sourdough pancakes, but I just was hoping for a non-frozen alternative for regular yeast.
