From blossom to bottle: A natural alternative to sulfites
In this Sustainable Wine Roundtable Member Interview podcast, I’m joined by Filipe Carvalho, head of business development at Tree Flowers Solutions (TFS), a Portuguese biotech startup that develops natural preservatives for the agri-food industry.
We discuss Chestwine, TFS’s innovative sulfite alternative made from chestnut male flower tannins. Filipe addresses common misconceptions about sulfites, explains why natural alternatives matter, and shares insights into the unique properties and R&D process behind Chestwine.
