Modern winemaking requires precision tools that respect the integrity of the grape. Our Fungal Chitosan for Wine offers a superior, non-animal alternative to traditional fining agents. Derived exclusively from Aspergillus niger, this high-purity biopolymer provides powerful stabilization and clarification without the risk of allergenic residues found in crustacean-based chitosan.<\/p>\n\n\n\n

Why Choose Fungal Chitosan for Winemaking?<\/h2>\n\n\n\n

Unlike standard fining agents, fungal chitosan for wine acts as a versatile problem-solver in the cellar. It is the gold standard for enologists seeking to reduce sulfites and eliminate contaminants.<\/p>\n\n\n\n

1. Control Brettanomyces & Volatile Phenols<\/h3>\n\n\n\n

The most critical application of vegan chitosan is Brettanomyces treatment. Its positive charge attracts and disrupts the cell membranes of spoilage yeasts like Brettanomyces bruxellensis. This significantly reduces viable yeast populations within days, preventing the production of volatile phenols (4-EP\/4-EG) that cause “horse sweat” or medicinal off-flavors.<\/p>\n\n\n\n

2. Oxidation Management for White & Ros\u00e9<\/h3>\n\n\n\n

For white and ros\u00e9 wines, oxidation is a major threat. Vegan chitosan acts as a selective chelator for heavy metals\u2014specifically Iron and Copper\u2014which are the catalysts for oxidation cascades. By removing these pro-oxidant metals, you preserve fresh color and fruity aromatics, extending the shelf-life of your vintage.<\/p>\n\n\n\n

    Frequently Asked Questions<\/h2>\n\n\n\n

    Is fungal chitosan allowed in organic winemaking?<\/h4>\n\n\n\n

    Yes.\u00a0Fungal chitosan derived from\u00a0Aspergillus niger<\/em>\u00a0is authorized for use in organic winemaking under EU regulations and is widely accepted due to its non-GMO and non-animal origin.<\/p>\n\n\n\n

    Does fungal chitosan affect the taste of the wine?<\/h4>\n\n\n\n

    No. When used at recommended dosage rates, fungal chitosan is insoluble and settles out of the wine after treatment. It respects the sensory profile of the wine while removing only the targeted contaminants (yeast or metals).<\/p>\n","protected":false},"excerpt":{"rendered":"
