What are the natural flavors in your Unsalted Butter?

The natural flavor is a natural milk derivative called a starter distillate, which is basically distilled flavors from fermented and cultured milk. This is added to the cream at levels which approximate the flavor profile of naturally-cultured butter prior to churning. (Starter distillate contains very low levels of diacetyl, which is an organic compound that gives unsalted butter a buttery taste).
