Purity Coffee Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Peet's Coffee is the best-performing purity coffee brand in July 2026, moving 30,000 units across 2 ASINs for 29.7% of Top 10 volume. Stumptown Coffee Roasters follows with 19,000 units (18.8%), ahead of Four Sigmatic on 10,000 units (9.9%).

Volume is spread across 8 brands, with the top three holding 58.4% 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 $14.92 to $19.74, 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, 2 ASINs forced its way in: B0936JKKJ2 booked 9K units at $13.24, with ▲ 200.0% MoM change. On the growth side, B0G1Z7XH1S leads positive momentum with ▲ 100.0% MoM growth on 6K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
