Strategies to Keep Whites & Rosés Bright, Stable, and Shelf‑Ready
Whether you're looking to retain freshness in tank or in bottle, there are several options beyond SO₂ that can help protect against oxidative damage, preserving color, aromatics, and overall longevity. These options also work well for low-alcohol or alcohol-removed wines.
Tannins
Gallnut tannin that can help to protect delicate aromas and color from oxidative damage.
A balanced blend of condensed and hydrolyzable tannins that can enhance and protect red fruity aromas.
Lightly toasted French oak tannin that supports aromatic freshness and contributes subtle structure.
Mannoproteins & Chitosan
Liquid mannoprotein that protects aroma compounds, stabilizes colloids, and can extend shelf-life in whites and rosés.
Liquid mannoprotein that stabilizes bubbles, colloids, and aromas in sparkling wines.
Chitosan and bentonite blend to remove undesirable aromas and oxidized compounds.
