• Performs reliably in difficult fermentations, including low nitrogen musts and high alcohol potential
• Ideal for restarting sluggish or stuck fermentations
• Tolerates extreme conditions: low temperature, low pH, high alcohol, and high sugar
• Neutral sensory profile preserves varietal character and wine structure
• Strong fermentation kinetics with rapid yeast biomass development

Enartis EZ Ferm 44 is a high-performance yeast strain developed for use in particularly challenging fermentation environments. It is especially effective in musts with low available nitrogen, high sugar content, and low temperature — conditions that often lead to sluggish or stuck fermentations. Its strong fermentative power, high alcohol tolerance (up to 17% v/v), and rapid biomass development make it an excellent choice for fermentation rescue operations and for fermenting difficult lots where reliability is critical. Rather than contributing intense aromatic esters, EZ Ferm 44 has a neutral profile that allows varietal and terroir characteristics to show through. It is also useful when the winemaking goal is to preserve structure and freshness without adding fruity overtones.

Protocol for Use:
Rehydrate in 10 times its weight of water at 35–38°C (95–100°F) for 20 minutes. After rehydration, slowly adapt the yeast to the must temperature by gradually adding must in small volumes over 10–15 minutes. Avoid temperature shocks greater than 10°C (18°F) between the yeast slurry and must. Inoculate immediately after acclimation is complete. For stuck fermentation restarts, follow a full restart protocol including detoxification and yeast acclimatization.

Usage Rate:
Recommended dosage is 20–30 g/hL
— 0.2–0.3 g/L
— 0.76–1.14 g/gal
