Almond meal

One US cup of almond meal weighs between 84 and 100 grams, depending on how the cup is filled and which source measured it. That range is the answer; a single number would not be. Every figure behind it is below, with the method each source used.

Also called almond meal, ground almonds, natural almond meal, unblanched almond meal, coarse almond flour.

Almond meal publishes as a range 84 to 100 grams per cup because two authoritative sources disagree by 16%, over the 10% milled tolerance, and the disagreement reflects real product variance in how almond meal is milled and labeled across the US market. King Arthur publishes 84 g/cup for almond meal (density 0.3551 g/mL). Bob's Red Mill Finely Ground Natural Almond Meal publishes 25 grams per 1/4 cup on its nutrition label, back-calculating to 100 g/cup (density 0.4227 g/mL). The 16-gram spread represents the honest span between coarser unblanched almond meal (KA reference) and finely-ground unblanched almond meal (Bob's finely ground product).

Understanding the range requires clearing up the ongoing confusion between almond flour and almond meal. Both are ground almonds, but as reference products they differ in two ways. Almond flour is typically made from blanched skin-removed almonds and ground to a fine uniform texture. Almond meal is typically made from unblanched skin-on almonds and ground more coarsely, retaining visible flecks of brown skin. King Arthur maintains this distinction cleanly with almond flour at 96 g/cup and almond meal at 84 g/cup — meal packs lighter because coarser particles and skin bits create more interstitial air. Many commercial producers use the terms interchangeably or hybrid them (labeling products as almond meal/flour), and this terminology confusion propagates through recipe writing.

Physical mechanism for the density spread: almond flour and meal both trap air voids at particle boundaries, but the relationship between grinding fineness, skin content, and pack density is non-monotonic. Blanched almond flour at fine grind packs densest (96 g/cup at KA) because uniform particle geometry allows efficient stacking. Unblanched almond meal at fine grind (Bob's Finely Ground) packs at 100 g/cup because skin bits break up the smooth stacking. Unblanched almond meal at coarser grind (KA reference) packs at 84 g/cup because larger particles create larger air gaps that outweigh the skin-fill effect. The relationship between fineness, skins, and density is genuinely counterintuitive.

USDA FoodData Central has SR Legacy entries for whole almonds — 12061 (Nuts, almonds, unblanched), 12062 (blanched, skin removed), 12063 (dry roasted, without salt), 12565 (oil roasted, with salt) — but none publish cup portions for milled meal specifically. This ingredient therefore relies on King Arthur cross-validated against Bob's Red Mill producer data. Bob's markets two almond meal products with different label densities: Finely Ground Natural Almond Meal at 25 g/quarter cup (100 g/cup, apparently measured), and Natural Almond Meal Flour at 28 g/quarter cup (112 g/cup, matches FDA RACC labeling standard and likely reflects labeling default rather than measurement).

Compared to other flours and meals on the site, almond meal at 84-100 g/cup packs meaningfully lighter than the wheat flour cluster (all-purpose 120 g/cup, whole wheat 113 g/cup, 00 pizza flour 116 g/cup). Nut particles compress less densely than starch granules under gravity alone because of the fatty, oily nature of almond particles — the fat coating reduces particle-to-particle friction and lets particles roll into more open configurations. Almond flour on this site sits at 96 g/cup at KA measurement, roughly in the middle of the almond meal range, reflecting the finer and cleaner particle geometry of blanched-fine flour versus unblanched-variable meal.

Category assignment is milled, matching almond flour and other nut and grain meals on the site.

Confidence is low because the two authoritative sources disagree over tolerance and the ingredient category has genuine grind-to-grind variance. For baking accuracy, weigh almond meal rather than measuring by volume. If a recipe was developed against KA references or a coarser almond meal, use 84 g/cup. If developed against Bob's Red Mill Finely Ground or another fine unblanched meal, use 100 g/cup. If in doubt, use 90 g/cup as a middle estimate for room-temperature stored almond meal. This entry represents a moat play for the site: no other cup-to-gram reference distinguishes coarse-unblanched from fine-unblanched almond meal with the physical explanation for the density variance, and no other reference explains why almond meal and almond flour market products overlap in weight despite their nominal distinction.
