Tartine Bakery

Tartine Bakery's bread is made through a process of natural fermentation using a levain, with yeast, bacteria, time, temperature, moisture, and fermentation acting on flour, water, and salt. The bakery uses flours that contain much or all of the original germ, oils, and bran. Those flours are milled by Cairnspring in Washington's Skagit Valley, a partner Tartine describes as taking as much care with milling and growing as it does with baking. Tartine's bakers speak with its millers on a regular basis, collaborating with each weekly grain shipment. Tartine and Cairnspring also work with farmers, including Hedlin Family Farms, to ensure the grain being milled is both sustainable and traceable, paying a premium for that premium product.
