EDINBURGH, UK – 19 June 2025 — Quas, the UK's Great Taste Award-winning producer of non-alcoholic kvass, today unveiled two major product innovations following two years of intensive research and development: a new high-fibre, reduced-sugar formula and a breakthrough shelf-stable version. These developments position Quas to scale nationally through ambient retail channels while directly addressing the UK's chronic dietary fibre gap, with studies showing around 90% of adults do not meet the recommended intake (BBC Food).
This achievement establishes Quas as a category leader, delivering more fibre per serving than any other fermented beverage in the UK and earning an official 'high-fibre' designation (UK Gov, 2024).
After testing dozens of different ingredient combinations and sugar alternatives, we've finally perfected a formula that significantly boosts fibre content and reduces sugar while enhancing the overall taste profile. Customer feedback during our pre-release trials has been overwhelmingly positive. — Dr. Anton Puzorjov, Founder of Quas and PhD in Biotechnology
High-Fibre, Reduced-Sugar Formula: The advanced recipe fully replaces the previous recipe for all Quas flavours and delivers 6.7 g of fibre per can (22% of daily recommended intake) while reducing sugar content from 3.8 g to 2.4 g per 100 ml—a 37% reduction. This formula combines prebiotic fibre with the hundreds of postbiotic metabolites naturally produced during fermentation.
Shelf-Stable Retail Format: A new, gently heat-treated non-filtered version offers a minimum six-month ambient shelf life. This innovation preserves the taste, prebiotic fibre and beneficial postbiotics, removing the cold chain barrier that has limited our growth in mainstream retail.
This changes everything for retailers. They can now stock a premium, award-winning fermented beverage on a standard shelf, completely de-risking inventory and opening up new opportunities. By making our product shelf-stable without sacrificing its beneficial properties, we're ready to bring Quas to more people across the UK and, eventually, globally. — Dr. Anton Puzorjov
