Polvere di fiori di castagno per dire addio ai solfiti nel vino
🍷 Portuguese researchers from the University of Bragança filed a patent in 2017 for a natural derivative from male chestnut tree flowers (castanea sativa) as a wine preservative, challenging the traditional use of sulfites (SO₂). The product, named "Chestwine," found favor in 2019 with a consultant for wine producers after successful tests. Marketed by startup "Tree Flowers Solutions," Chestwine is now used in the Spanish and Portuguese markets and is undergoing testing in Bordeaux estates. Chestwine's polyphenolic richness is claimed to be at least as effective as SO₂ in inhibiting oxidation and microbial growth without being allergenic or affecting wine taste or color.
