My friend Christy investigated organic vs. regular yeast and how they are made, and finally I’m taking some time to investigate this myself. I’m a sourdough baker, but sometimes I use yeast to make breads. I thought I’d order some organic yeast to play around with, but Amazon told me they were out of stock. Why is organic yeast so hard to find? Can I make it, I wondered…
Shipton Mill (England) tells the story of barm so beautifully. Compare organic vs. non-organic yeast for yourself.
