PREMIUM UVA
TANNIN FOR OENOLOGICAL USE
COMPOSITION
Grape-extracted tannin for enological use.
CHARACTERISTICS
PREMIUM UVA has the same structure as tannin naturally present in ripe grapes. Its procyanidinic and catechinic origin formula, makes the tannin highly reactive towards proteins, including polyphenol oxidized, and towards coloring agents.
PREMIUM UVA gives wine a longer shelf life and resistance to oxidation. Wines treated with this product have more complex bouquet and greater body.
APPLICATIONS
PREMIUM UVA is used to treat red and white \vines. yinegar and distilled spirits. For wines it is used in the initial phases and during finishing. Use in must and young wines from botrytis infected grapes prevents oxidation processes caused by botrytis enzymes. For red wine. it is used during maceration and drawing off to fix the anthocyanic fractions extracted from the skin. PREMIUM UVA is used to treat white wines to improve protein stability because it decreases the quantity of bentonite to be added, protecting the integrity of the product. Its antioxidant action means that less sulfur dioxide is needed to stabilize the wine. Please use PREMIUM UVA in compliance with all applicable regulation.
