Einkorn Flour Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

King Arthur is the best-performing einkorn flour brand in July 2026, moving 64,000 units across 5 ASINs for 62.1% of Top 10 volume. Amazon Grocery follows with 20,000 units (19.4%), ahead of 365 by Whole Foods Market on 14,000 units (13.6%).

With 4 brands splitting the Top 10 and 95.1% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $2.75 to $7.51, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. On the growth side, B071YHMGRZ leads positive momentum with ▲ 233.3% MoM growth on 1K units, with B09PF5RFG1 close behind at ▲ 133.3% MoM on 700 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
