What is Flour Extraction?

Extraction rate refers to the percentage of the whole grain that remains in the flour after milling and sifting. A higher extraction rate means more of the original grain is retained, including bran and germ, which contributes to flavor, nutrition, and color.

The T-rating system (e.g., T-55, T-65, T-85) is based on the ash content and is commonly used in Europe, especially France. It indicates how much of the grain is included in the flour and helps bakers understand the flour’s composition.

Whole grain flour contains 100% of the original grain: endosperm, bran, and germ. It’s best for hearty artisan breads, rustic loaves, and nutritionally focused baking. Expect bold flavor, darker color, and dense texture.

T-85 flour contains about 92% of the grain, striking a balance between whole grain and refined flours. It delivers great flavor with a lighter texture and is perfect for artisan breads, pizza dough, and sourdough with plenty of chew.

T-65 is similar to all-purpose flour in the U.S. It contains about 65% of the original grain and is ideal for country breads and baguettes. Expect a lighter crumb with some wheat character.

T-55 flour is finely sifted and very low in bran and germ, resulting in a soft, light flour. It’s perfect for pastries, cakes, croissants, and other delicate bakes where texture matters most.
