The Lalvin ICV-K1 V1116 Dried Active Yeast serves as a cornerstone in the world of home and professional wine-making, offering an indispensable tool for those aiming to create exceptional wines. Each package includes five 5-gram sachets, designed to treat wine batches ranging from 1 to 5 gallons (4.5L to 23L). This yeast strain is particularly distinguished for its versatility, being well-suited for fresh fruit and dry white wines, aged red varieties, and late harvest wines. Among the vast selection of wine yeasts available in the market, Lalvin stands out as one of the most recommended options, favored for its reliability and performance consistency.
The remarkable qualities of the Lalvin ICV-K1 (V1116) yeast strain are a product of its background in commercial fermentation, making it one of the most widely used active dried yeasts globally. One of its standout features is its high alcohol tolerance, which extends up to 18% ABV. Such a robust tolerance means winemakers can confidently ferment higher alcohol wines without risking stuck fermentations, a common concern among lesser yeasts. This yeast also exhibits a notably short lag phase, allowing users to experience a quicker onset of fermentation, crucial for maintaining quality and flavor stability.
Operating effectively within a broad range of fermentation temperatures from 10°C to 35°C, the Lalvin ICV-K1 proves to be adaptable to various environmental conditions. This flexibility is essential for amateur and seasoned winemakers alike, who may not always have strict temperature control over their fermenting environment. Further enhancing its appeal is the yeast's low production of hydrogen sulfide (H2S), volatile acidity, and foam, which contribute to a more pleasant fermentation experience. When managed correctly, especially with the right nutrient additions, ICV-K1 produces floral esters that enhance the aromatic profile of wines, enriching neutral grape varieties with fresh and enticing flavors.
Ultimately, the Lalvin ICV-K1 V1116 Dried Active Yeast emerges as an exemplary choice for those dedicated to crafting outstanding wines. Its combination of high alcohol tolerance, broad temperature range, and capacity for floral aroma production makes it a dependable ally in the fermentation process, appealing to both hobbyists and professionals. With five sachets per package, users can experiment with a multitude of wine styles while enjoying the consistency that the Lalvin brand is renowned for.
