Estaan: A Plant-Based Tannin as an Alternative to SO₂ in Winemaking

This presentation introduces a plant-based polyphenolic alternative to SO₂ and highlights its practical applicability in winery operations. Real-scale trials demonstrate that the formulation effectively manages oxidation and microbial stability while enabling a substantial reduction in SO₂ use. The talk will present key experimental results, discuss critical sensory outcomes in musts and wines, and outline the operational considerations for implementation in commercial cellars. The findings contribute to the growing need for sustainable, low-sulfite solutions in contemporary
wine production.
