Sprouted Wheat Flour

One US cup of sprouted wheat flour weighs 120 grams. Going the other way, 100 grams is about 0.83 cups.

Also called sprouted whole wheat flour, sprouted whole wheat, sprouted wheat, sprouted red wheat flour, sprouted white wheat flour.

Sprouted wheat flour weighs 120 g/cup spooned and leveled, correcting the King Arthur ingredient weight chart figure of 113 g/cup.

Sprouted wheat flour is made by soaking whole wheat berries until they germinate, then dehydrating and milling the sprouted grain. The sprouting process activates enzymes that partially break down the grain's starches and reduce phytic acid, which many bakers find produces a milder, sweeter flour that some people with wheat sensitivities tolerate better than conventional whole wheat. The resulting flour is always whole grain in retail form — there is no sifted or all-purpose sprouted wheat flour on the market. Producers use either hard red wheat berries (Arrowhead Mills, To Your Health's red wheat SKU) or hard white wheat berries (King Arthur's discontinued product, One Degree, To Your Health's white wheat SKU); the sprouting process affects density more than the wheat variety does.

The correction against KA is unusually well-supported because KA contradicts itself. Their Ingredient Weight Chart lists Sprouted Wheat Flour at 4 oz per cup (113 g), but the FDA-regulated nutrition facts panel on their own 100% Whole Grain Sprouted Wheat Flour bag stated 30 g per 1/4 cup — which works out to 120 g/cup. The 113-g figure follows the same pattern seen this project session with sweet rice flour and hazelnut spread: KA appears to anchor certain chart entries on a nominal ounce value and convert to grams via unit substitution rather than measuring density directly. The 4-oz callout on their sprouted wheat flour packaging ("1 cup of Sprouted Wheat Flour equal to 113 g (4 oz)") reinforces this — the chart and the packaging callout march together at 113 g, but the actual regulated nutrition label tells the truer story at 120 g. King Arthur discontinued the product entirely, but the chart entry remains and continues to influence recipes online.

Producer convergence at 120 g/cup is tight. One Degree Organic Foods, To Your Health Sprouted Flour Co., and King Arthur's own nutrition label all report 30 g per 1/4 cup serving, giving 120 g/cup across three independent brands with different wheat varieties and different milling operations. This matches the physical density expected for a lightly-spooned whole-grain flour milled from sprouted grain: 0.507 g/mL, on the low end of the whole wheat range because the sprouting process makes the endosperm more brittle and reduces particle packing efficiency slightly.

One notable outlier: Arrowhead Mills labels their Organic Sprouted Wheat Flour at 39 g per 1/4 cup, giving 156 g/cup — 30 percent above the three-source convergence. This is best understood as brand-wide methodology variance rather than a signal about the ingredient itself. Arrowhead's regular whole wheat flour is labeled at 35 g per 1/4 cup (140 g/cup), also above the ~120 g/cup norm for that product. The Arrowhead figures are consistent with a dip-and-sweep methodology applied across their line rather than the spoon-and-level convention that FDA labeling assumes. Bakers using Arrowhead flour specifically should either measure by weight or expect their cup measurements to weigh roughly 30 percent more than most recipe developers assume.

Bob's Red Mill is often listed as a sprouted wheat flour brand (Amazon's category filter includes them) but does not actually sell sprouted wheat flour as a distinct SKU. Their sprouted wheat recipes on the BRM site call for home-sprouted wheat berries used alongside their regular stone-ground whole wheat flour.

Practical guidance: for the dominant retail brands (One Degree, To Your Health, and legacy KA), weigh at 120 g/cup or substitute 1:1 by volume for whole wheat flour in existing recipes. For Arrowhead, weighing is strongly preferred over volume measurement.
