Raw Milk Raw means fresh milk that has not yet been pasteurized. Raw milk is rich in a plethora of “good bacteria,” and rich flavor-producing enzymes that make it a coveted resource for many artisan cheesemakers. Because of the diversity of bacteria, raw milk can also be a bit of a wild card and is not readily welcomed in certain markets and products. In the U.S., laws surrounding the sale of raw fluid milk vary from state to state. When it comes to cheese, however, Uncle Sam has a say. Legally in the U.S., raw milk cheese must currently be aged for at least 60 days. Any fresh cheese in the U.S. that is available for sale is pasteurized.
