Buttermilk Powder Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Organic Valley is the best-performing buttermilk powder brand in July 2026, moving 10,000 units across 1 ASIN for 21.3% of Top 10 volume. 365 by Whole Foods Market follows with 10,000 units (21.3%), ahead of Hoosier Hill Farm on 8,000 units (17.0%).

Volume is spread across 9 brands, with the top three holding 59.6% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $3.79 to $17.49, 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: B00DC5ZKQE booked 2K units at $19.99, with ▲ 122.2% MoM change. On the growth side, B00V3M8XRG leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B0CLFXDX4Z close behind at ▲ 50.0% MoM on 3K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
