Earl Grey Tea Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Twinings is the best-performing earl grey tea brand in July 2026, moving 14,000 units across 2 ASINs for 50.0% of Top 10 volume. Harney & Sons follows with 5,000 units (17.9%), ahead of Bigelow Tea on 5,000 units (17.9%).

With 5 brands splitting the Top 10 and 85.7% 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 $8.83 to $16.13, 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, B000GG1O6M leads positive momentum with ▲ 100.0% MoM growth on 100 units, with B0BL891P8D close behind at ▲ 33.3% MoM on 800 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
