Honey Mustard Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

365 by Whole Foods Market is the best-performing honey mustard brand in July 2026, moving 16,000 units across 2 ASINs for 32.7% of Top 10 volume. Grey Poupon follows with 12,000 units (24.5%), ahead of Maille on 7,000 units (14.3%).

With 6 brands splitting the Top 10 and 71.4% 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 $2.49 to $4.55, 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. Specifically, one ASIN forced its way in: B00408NAPA booked 2K units at $4.27, with ▲ 0.0% MoM change. On the growth side, B000WG65UG leads positive momentum with ▲ 150.0% MoM growth on 5K units, with B08W3BSQR4 close behind at ▲ 100.0% MoM on 200 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
