Features and Benefits
Formulation: Inactivated yeasts (Saccharomyces cerevisiae) naturally rich in glutathione.
Enological benefits:
- Glutathione (GSH) is a sulfurous tripeptide that is naturally found in cells and has a strong reducing capacity, giving it an important role in the fight against oxidation.
- Aroma Protect® is rich in reducing compounds and adds GSH precursors to the must. These precursors are used by the yeast during the alcoholic fermentation to synthesise and accumulate GSH, which is then released through autolysis when the wine is aged on the lees.
- It also contains GSH, which is directly available for effective control of oxidative mechanisms in wines.
- By significantly slowing down oxidative phenomena, Aroma Protect® preserves wines’ aromas and freshness.
Product Applications
Dissolve the product in 10 times its weight in water. Proper management of nitrogen nutrition for yeasts is crucial to achieve the best effectiveness of Aroma Protect®.
Dosage:
- Protection against oxidation: 30 g/hL at the end of alcoholic fermentation (AF) (density ≈ 1.010)
- For wines to be bottled quickly after fermentation (within 3 months): 15 g/hL to modulate the reductive effect
