AMASS Brands Group's Good Twin Retail Sales Accelerate 136%, Nearly 8x the Growth Rate of the U.S. Non-Alcoholic Wine Category

SANTA MARIA, Calif., Sept. 15, 2026 (GLOBE NEWSWIRE) -- AMASS Brands Group (NASDAQ: AMSS) ("AMASS" or "the Company"), a premium, multi-category beverage platform spanning non-alcohol, functional, and alcohol 2.0 products, today announced that Good Twin, the Company's organic non-alcoholic sparkling wine, grew retail sales 136% year over year during the four weeks ended August 8, 2026, nearly eight times the 17% growth of the broader U.S. non-alcoholic wine category, according to NielsenIQ.¹

Importantly, Good Twin's growth continues to accelerate rather than moderate. Year-over-year retail sales increased 95% over the trailing 52 weeks, 111% over the trailing 13 weeks and 136% during the latest four-week period, the strongest growth rate of the year. Retail case volume increased 128%, making Good Twin the second-fastest-growing brand among the top 15 non-alcoholic wine brands in the United States.¹

The data also suggests Good Twin's growth is being driven by consumer demand rather than expanded distribution. Dollar sales per point of distribution increased 75% year over year, the fastest velocity improvement among the top 15 non-alcoholic wine brands, while the brand's absolute retail velocity ranked among the top three in the category. At the same time, Good Twin gained a statistically significant 0.58 share points within the non- alcoholic wine category while relying more heavily on expanded displays than promotional discounting, indicating healthy consumer demand rather than price-driven volume. ¹

"Good Twin's growth isn't just continuing, it's accelerating," said Mark Thomas Lynn, Founder and Chief Executive Officer of AMASS. "We're seeing stronger consumer demand across both wholesale and direct-to-consumer channels while the brand still reaches only a fraction of the stores served by many of its largest competitors. When retail velocity is accelerating faster than distribution, it tells us demand is outpacing shelf space. That's exactly the position we want to be in because it creates a long runway for future growth as we continue expanding distribution."

Good Twin's retail momentum continues to strengthen across multiple measures. The brand now ranks as the #13 non-alcoholic wine brand in the U.S., #1 organic non-alcoholic wine priced under $20, #2 organic non-alcoholic wine overall and #6 non-alcoholic sparkling wine nationally. ¹ That retail momentum is being reinforced by record direct-to-consumer performance. August was the strongest month in the brand's history, surpassing the previous monthly sales record by 11% and July by 15%. Direct-to-consumer revenue increased 569% year over year as order volume rose 500%, while the brand also established new monthly records for orders, customers and average order value. Importantly, that growth was achieved with lower promotional spending than the prior year, demonstrating continued pricing discipline. Returning customers increased roughly sevenfold, subscription orders grew 6.5 times year over year and Good Twin expanded its shipping footprint to 47 states, up from 35 a year earlier.²
