Description

  • Lalvin CY3079 is the go-to choice for winemakers aiming to craft full-bodied, complex Chardonnay and barrel-aged whites with rich mouthfeel, creamy texture, and elegant oak integration
  • Whether perfecting a Chardonnay or refining a white Burgundy, CY3079 ensures a smooth, layered finish with exceptional aromatic clarity
  • Enhance complexity and mouthfeel in premium Chardonnay and barrel-aged whites

Lalvin CY3079 is a specially selected wine yeast strain renowned for its ability to develop rich mouthfeel, enhanced complexity, and buttery characteristics during fermentation. Perfectly suited for Chardonnay and other barrel-aged white wines, CY3079 promotes the release of polysaccharides and encourages malolactic fermentation, resulting in wines with balanced acidity, smooth texture, and vibrant aromatics.

  • Enhanced Mouthfeel: Promotes polysaccharide synthesis, delivering a creamy, full-bodied texture.
  • Malolactic Compatibility: Optimized for seamless transition into malolactic fermentation, enhancing buttery and nutty notes.
  • Aromatic Development: Elevates apple, pear, vanilla, and toasted almond aromatics.
  • Alcohol Tolerance: Supports ABV levels up to 15%, allowing complete fermentation in high-sugar musts.
  • Attenuation Rate: Typically achieves 85–90% attenuation, ensuring a dry, well-structured finish.
  • Temperature Range: Performs optimally between 59°F (15°C) and 77°F (25°C), with the best expression of mouthfeel and complexity around 64°F (18°C).
  • Medium Flocculation: Settles well post-fermentation, enhancing clarity and reducing sediment.

Applications:

  • Chardonnay: Ideal for barrel-fermented Chardonnay, bringing forward rich mouthfeel and buttery notes.
  • White Burgundy: Elevates minerality and complexity, emphasizing ripe fruit and toasty oak integration.
  • Viognier: Enhances stone fruit and floral notes, adding depth and roundness.
  • Barrel-Aged Whites: Perfect for oaked Sauvignon Blanc and Semillon, adding creaminess and layered complexity.

Flavor Profile: 

  • Stone Fruits & Citrus: Boosts expressions of apple, pear, and lemon zest.
  • Buttery & Nutty Notes: Develops butter, vanilla, and toasted almond during malolactic fermentation.
  • Rich Mouthfeel: Promotes a creamy, well-rounded palate with smooth, integrated texture.
  • Oak Integration: Complements toasted oak, enhancing complexity and balance.

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 mouthfeel and flavor development.
  • Nutrient Addition: Supplement with yeast nutrient to optimize fermentation and promote aromatic development.
  • Fermentation Temperature: Maintain between 59°F (15°C) and 77°F (25°C), with 64°F (18°C) being ideal for creaminess and complexity.
  • Barrel Fermentation: Ideal for in-barrel fermentations to enhance oak integration and complexity.

Mostly Frontenac Blanc,plenty of Gewertztraminer with some cameo appearances by some of my other random planting choices. If you want a hardy vinifera in a marginal climate (6b) Gewertztraminer is a champ.

Really happy with this yeast
I'm really happy with the outcome of this yeast. I used it alongside EC1118 for a Chard kit wine and I'm so impresed with the results. I wasn't sure how it would turn out and was hesitant. I'm so glad I did.

Hoping for good things.
Not sure how the wine is going to turn out but the yeast fermented all the sugar just fine. Wasn’t really wowed by the must at any stage but there were no off smells or stalling so I am hopeful the yeast will add some quality because the grapes were kind of flat, no rot, fully ripe, just no “pizazz” if you will. So if the wine does come around the yeast is going to have to do the lifting

CY3079, bad yeast package
I bought an 80 gram Cy3079 package for my Chardonnay. I inoculated. Sunday, properly hydrated with go-ferm protect, good time frame, temperatures correct and within parameters. Monday morning I fed with mermaid K, but there was little to no activity, still nothing Monday evening so I reinoculated with the yeast I had left and with the needed go-ferm protect.
Tuesday evening, no activity so I went to the local wine and brew supply store and purchased 55 grams of D47, inoculated with even more go Ferm protect and Tuesday morning I have a very violent fermentation going on. Bad Yeast is all I can figure. Now I'm low on go Ferm protect for my other fermentations in a couple of weeks
