There is a wide variety of flours in the bulk area. Here are a few key things to know about some of the most commonly used flours:
ALL PURPOSE FLOUR This flour is a blend of high gluten hard wheat and low gluten soft wheat flour. It has been stripped of its germ and bran. It is enriched with three B-vitamins, folic acid and iron.
WHOLE WHEAT BREAD FLOUR This flour is a higher protein flour due to its higher gluten content that produces a better bread. The protein content of this flour is 10 to 14% and the flour is from hard red spring or winter wheat.
WHOLE WHEAT PASTRY FLOUR This is a whole grain flour made from soft wheat and has a lower protein content than bread flour (9-10 %) and is more suited to quick breads, muffins and cookies. It provides a similar product to all purpose flour but it is totally whole grain.
RYE FLOUR This flour has a distinctive flavor and a moderate amount of gluten, and needs to be mixed with wheat bread flour usually to make a decent bread otherwise it makes a dense small bread. Dark rye flour is preferable to light rye flour since dark rye flour contains the bran and germ.
WHITE WHEAT FLOUR This flour is milled from hard spring wheat but it has no genes to produce the dark brown bran color. It produces a good baked product and has the same nutritional value as whole wheat but with a milder taste and good texture. The gluten content is not high, similar to whole wheat pastry flour so it is not good for making bread.
GLUTEN-FREE FLOURS These are some of the gluten-free flours that are available in the bulk section. They are set apart from the other flours (across from the coffee) due to concerns with cross contamination: rice flour, amaranth flour, almond flour, quinoa flour, chickpea flour, all-purpose gluten-free flour, all purpose baking flour, teff flour, sorghum flour, coconut flour, and buckwheat flour.
