Purple Cabbage Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

365 by Whole Foods Market is the best-performing purple cabbage brand in July 2026, moving 350,000 units across 4 ASINs for 38.9% of Top 10 volume. Fresh Produce (Brands May Vary) follows with 180,000 units (20.0%), ahead of Amazon Grocery on 170,000 units (18.9%).

With 5 brands splitting the Top 10 and 77.8% 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 $1.49 to $3.41, 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: B07FWN3244 booked 60K units at $3.48, with ▲ 20.0% MoM change. On the growth side, B07X819GF7 leads positive momentum with ▲ 300.0% MoM growth on 200 units, with B01MEEJDXR close behind at ▲ 200.0% 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
