-
High Ester Production: Enhances floral and fruity aromas, including notes of apple, citrus, and tropical fruits.
-
Cold Fermentation Tolerance: Performs well at low temperatures, preserving delicate aromatics.
-
Alcohol Tolerance: Effective up to 18% ABV, allowing for complete fermentation in high-sugar musts.
-
Fermentation Range: Operates optimally between 50°F (10°C) and 95°F (35°C), providing flexibility across various wine styles.
-
Low Nutrient Requirements: Thrives in musts with low nutrient content, reducing the need for supplementation.
-
Low H₂S and SO₂ Production: Ensures clean fermentations with minimal off-flavors.
Applications:
-
White Wines: Sauvignon Blanc, Chenin Blanc, Riesling, and Pinot Grigio, where bright fruit and floral characteristics are desired.
-
Sparkling Wines: Suitable for traditional method and Charmat process, promoting fine bubbles and crisp acidity.
-
Fruit Wines: Enhances the natural fruit expression in apple, pear, peach, and berry wines.

Floral Undertones: Light notes of honeysuckle and orange blossom contribute to aromatic lift.
-
Clean, Crisp Finish: Maintains a fresh, pure expression of fruit with minimal sulfur notes.
Usage:
-
Rehydration: Rehydrate in 10 times its weight of chlorine-free water at 95°F (35°C) for 15–20 minutes. Stir gently to avoid clumping.
-
Pitch Rate: Use 1–1.5 grams per gallon (0.25–0.4 grams per liter) for optimal fermentation and flavor development.
-
Nutrient Addition: While K1 (V1116) has low nutrient requirements, supplementation is recommended in low-nitrogen musts to prevent sluggish fermentation.
-
Fermentation Temperature: Maintain between 50°F and 95°F to optimize ester formation and maintain clarity.
