ViniLiquid™: What 15 Years Has Taught Us About Fermentative Power

When Fermentis first introduced ViniLiquid™, the concept was straightforward: a yeast autolysate fermentation activator, formulated and stabilized as a liquid. Over the next 15 years, winemakers reported faster, more complete fermentations, healthier yeast populations, and wines with more expressive aromatics. The liquid format wasn’t just a packaging decision—it was a technical one.

The key insight from 15 years of field data:

Physical form matters as much as nutrient composition when it comes to fermentative power. ViniLiquid™ was the first yeast autolysate fermentation activator produced and stabilized in liquid form, driving measurable differences in yeast behavior.

Rethinking What “Fermentation Nutrition” Really Means

Most conversations about fermentation nutrition focus on nitrogen (YAN). However, fermentative power is the combined capacity of a nutrient to:

• Increase fermentation speed and reduce overall time
• Support fermentation completion under stress
• Maintain yeast viability, especially in late stages
• Reduce stress factors detrimental to lactic acid bacteria

What Drives Fermentative Power?

YAN is important, but fermentative power also depends on:

• Insoluble support elements (yeast hulls)
• Survival factors (sterols, unsaturated fatty acids)
• Growth factors (vitamins, minerals)
• The physical form of delivery

Yeast derivatives address these dimensions simultaneously. Research confirms that compounds like peptides, sterols, and mannoproteins improve cell membrane integrity and modulate wine aroma.

Why the Liquid Format Changes Everything

ViniLiquid™ is a highly degraded yeast autolysate combining soluble and insoluble fractions in a stable liquid matrix. This preserves bioavailability better than dry formats.

Superior Fermentative Power vs. Dry Autolysates

In trials, ViniLiquid™ reduced fermentation time by up to 42% when combined with oxygen micro-addition, outperforming dry alternatives.

Why does liquid form make a difference?

The liquid autolysate disperses immediately, ensuring survival factors and sterols are available without lag time.

Better Yeast Viability, Especially Late in Fermentation

ViniLiquid™ boosts yeast population and viability in the second half of fermentation, reducing stuck fermentations and improving predictability.
