What is sourdough yeast?
Sourdough breads are famous in the San Francisco area. The yeast is of a slightly different breed, Saccaromyces esigus. It multiplies at a much lower rate than standard baker's yeast. The resulting product is much more compact and dense.The end product is more acidic because the yeast cannot digest maltose sugar, thus a certain type of indigenous San Francisco bacteria takes over. It is the byproduct of the bacteria which is highly acidic, giving that characteristic sourdough flavor.
