Wine Fermentation Additives

RedStyle – Lallemand Maceration Aid for Enhanced Color, Structure & Tannin Smoothness Enhances color intensity and stability through polysaccharide–polyphenol complex formation Improves tannin integration, reducing harshness and green characters Boosts juice extraction and clarity during maceration with built-in pectinase Builds fuller body and smoother mouthfeel without overwriting varietal character Offers dual-action benefits (enzyme + yeast derivative), outperforming generic macerators RedStyle combines a gentle pectinase enzyme with a specially selected and inactivated wine yeast derivative rich in soluble polysaccharides. When applied during red grape maceration, it breaks down pulp and skin walls—including pectin—enhancing juice yield and extraction. The released polysaccharides bind with anthocyanins and tannins, promoting richer color, more refined tannin structure, and a round, balanced body. The integrated enzyme also improves clarification and filterability, helping winemakers craft wines that are visually appealing, texturally complete, and varietally expressive. Protocol Suspend RedStyle in ten times its weight of clean must or water (e.g., 1 kg in 10 L). Stir thoroughly to ensure full dispersion. Add directly after crushing, either into the crusher, at the start of filling, or during initial pump-overs. Maintain suspension during addition to ensure even distribution. Usage Rates Recommended dosage: 30 g per hectoliter = 0.3 g per liter = 1.14 g per gallon For dosage expressed per ton of grapes: 227 g per ton (≈ 0.5 lb/ton). This balanced rate delivers optimal color stabilization, tannin smoothing, and maceration performance for most red wine styles.

Yeast Derivative Nutrient - For increased color stability, integrated mouthfeel and roundness in red wines; OMRI listed OPTI-MUM RED™ helps to produce wines with intense color, a rounder, softer mouthfeel, and a decreased perception of astringency. Early additions of OPTI-MUM RED lead to more stable color due to reactions between early-released color molecules (anthocyanins), phenolic compounds (tannins), and the polysaccharides from OPTI-MUM RED Reduces the perception of green, astringent tannins in cool-climate or low maturity fruit Reduces the sensation of hotness in high alcohol wines Can help soften mouthfeel The yeast strain behind OPTI-MUM RED was specifically selected and fully autolyzed for its highly reactive high molecular weight polysaccharides and oligosaccharides   Frequently used in: Medium-bodied reds, full-bodied reds, cool-climate reds, high maturity grapes When to add: Directly to grapes or at first mixing Provides: High molecular weight polysaccharides and oligosaccharides that contribute to color stability, volume, and softness YAN contribution: Insignificant   Recommended Dosage: 20-40 g/hL (1.7-3.3 lb/1000 gal)  Usage: Mix OPTI-MUM RED in 10 times its weight of water or juice and add directly to the grapes or must. If adding later in fermentation, add during a pump-over or during tank mixings. This product is mostly soluble. Stir to maintain suspension before and during addition. Storage: Dated expiration. Store in a cool, dry environment at 18°C (65°F). Once opened, keep tightly sealed and dry.

GlutaStar – Lallemand Yeast Derivative for Enhanced Glutathione Protection Improves protection against oxidation during aging and storage Delivers high concentrations of reduced glutathione (GSH) for maximum antioxidant effect Enhances tropical and citrus aroma stability, especially in thiol-rich varietals Boosts mouthfeel and roundness without increasing bitterness Outperforms traditional inactivated yeasts with a more targeted composition and higher GSH yield GlutaStar is a next-generation specific yeast derivative developed by Lallemand using a proprietary process that yields exceptionally high levels of naturally reduced glutathione. Designed for use in white and rosé wines, especially those with delicate thiol-driven profiles, GlutaStar helps lock in freshness and prevent oxidative damage during maturation, bottling, and shelf life. In addition to preserving bright aromas like grapefruit, passionfruit, and lemon zest, it contributes to a rounder mouthfeel without adding astringency. Compared to conventional inactivated yeasts, GlutaStar delivers superior antioxidant protection and stability, particularly when used early in the winemaking process. Usage Rates White and rosé wines: 0.2–0.4 grams per liter Equivalent to: 0.76–1.5 grams per gallon Protocol Rehydrate GlutaStar in ten times its weight of water at 30–35°C. Let sit for 10 minutes, then stir thoroughly. Add to must or wine at the beginning of fermentation or at the end of fermentation, depending on the goal. Do not combine directly with bentonite or tannins to preserve efficacy. Storage: Dated expiration. Store in a cool and dry environment at 18°C (65°F). Once opened, keep tightly sealed and dry.
