Yeast Derivative Nutrient - For rounder and smoother tannins in reds; OMRI listed
OPTI-RED® may be used to produce wines with stable color, round mouthfeel, and smooth tannins.
- Quick release of polysaccharides that participate in color stabilizing reactions when added at the onset of fermentation
- As OPTI-RED breaks down, additional polysaccharides can complex with tannins resulting in round mouthfeel and smooth tannins
- When used in the later stages of fermentation it shapes harsh polyphenolics into smoother, more approachable tannins
- OPTI-RED is an inactivated and partially autolyzed yeast derivative
Frequently used in: light-bodied reds, medium-bodied reds
When to add: Anytime during alcoholic or malolactic fermentation
Provides: High molecular weight polysaccharides - early use promotes color stability and late use smooths harsh tannins
YAN contribution: Insignificant
Recommended Dosage: 30 g/hL (2.5 lb/1000 gal)
Usage: Mix OPTI-RED in 10 times its weight of must or water and add during a punch-down or a
pump-over to ensure OPTI-RED is mixed in well. This product is partially soluble. Stir to maintain
suspension before and during addition.
