AMA Brewery

AMA Brewery was born in San Sebastián, Spain, and is based in Irun. The project was conceived by two chefs working at the forefront of global gastronomy together with an artisanal vigneron. Work on what the founders call their Pet Nat Teas project began in 2017.^[1],[2]

In late 2025, AMA Brewery launched a non-alcoholic series, rebranding its fermented sparkling teas. The producer has received public funding for its work: from the European Union Next Generation EU program under the 2024 Applied AI and Data Strategy call, and from the Basque Government's Department of Industry, Energy Transition and Sustainability together with the European Union (FEDER) under the 2025 Hazitek call.^[2]

Dani Lasa — Executive Director. Dani Lasa is a chef and Executive Director of AMA Brewery, as well as a co-founder of the company and of Bombyx Mori SL. He built his career as head chef of fine dining restaurants and developed a long-standing interest in kombucha's potential as a food-pairing drink, drawn to fermentation's impact on structure, flavour, and acidity. In an account dated to the producer's social media, Lasa balances multiple roles: making pizzas at Humo Pizza Gros, cooking private lunches at Dotore, lecturing at a university, and hands-on brewing at AMA Brewery.

Ramón Perisé — Technical Director. Ramón Perisé is a chef and Technical Director of AMA Brewery. He spent many years working in the R&D department of a fine dining restaurant, where he became passionate about natural yeasts and spontaneous fermentations. AMA credits Perisé with discovering the importance of aging for kombucha: early bottles he inadvertently left to age for several weeks exploded, while those that remained reached what the producer describes as a point of excellence. The Pét-nat tea project is led by Lasa and Perisé together.

Sancho Rodríguez — Co-founder, winemaker. AMA's third co-founder is Sancho Rodríguez, an artisan winemaker who grew up on the 14th-century Granja Remelluri estate in Rioja. His father purchased the vineyard in 1967 and never used chemicals or artificial fertilizers.^[1]

Aaron McAllister — Production Manager. Aaron McAllister, originally from the UK, became Production Manager at AMA full-time in 2021.^[3]

Wider team. The project is supported by a team of fine dining chefs, artisan winemakers, scientists, craftsmen, and tea experts.^[4]

Basque spring water. Pure spring water from the Basque Country is a core ingredient in AMA's drinks. The water originates from the Alzola spring, having taken 27 years to filter through flysch rocks before emerging.^[5]
