Sparkling wine is one of the most expressive and technically demanding wine styles. Its character begins with the grape variety, the vineyard, and the production method, but the final sensory signature depends heavily on yeast. Yeast acts as the invisible winemaker, shaping aroma, flavor, texture, and bubble structure throughout both primary and secondary fermentations. Different strains of Saccharomyces cerevisiae behave very differently under the challenging conditions of sparkling wine production. Low pH, increasing alcohol, and high pressure create an environment where only the right strains thrive. Equally important, each strain varies in its ability to create and release the flavor compounds that drive complexity and define style. When secondary fermentation takes place in the bottle and is followed by proper riddling, the yeast has an even greater influence on the final profile. To help winemakers better understand the impact of yeast selection, ATPGroup conducted a focused tria

A smooth, complete fermentation doesn’t happen by chance, it starts with balanced yeast nutrition. When yeast has access to the right nutrients at the right time, you avoid sluggish or stuck fermentations, reduce the risk of Hâ‚‚S and VA, and unlock the full aromatic potential of your grapes.  Why Yeast Nutrition Matters? Nitrogen is the main driver of yeast growth and fermentation activity. Saccharomyces can assimilate only ammonium ions (DAP), amino acids (organic nitrogen), and small peptides (organic nitrogen). Amino acids are strategic: they are taken up early, stored, and used gradually. Some of them also act as aroma precursors (thiols, esters, acetates). Vitamins & minerals (thiamine, Mg, Zn) act as cofactors in enzymatic reactions and have a role in cell growth, fermentation activity, and nitrogen metabolism. Sterols & long-chain fatty acids are essential for membrane structure, stress resistance, and survival. Click here for all fermentation tips & gui

Renaissance Yeast’s strains have excellent fermentation kinetics, desirable sensory characteristics, and are produced to the highest quality standards. Renaissance Yeast is the exclusive developer of a novel, patented H2S-preventing technology that is the result of a natural trait in yeast that increases sulfur and nitrogen utilization efficiency during fermentation, thereby preventing hydrogen sulfide formation.  Ossia (Saccharomyces cerevisiae hybrid), Renaissance Yeast’s organic H2S-preventing strain, recommended for organic dry white and red wines, fruit wines and cider.

We’re joined by Paolo Antoniali, CEO of Italiana Biotecnologie, to explore the potential of non-Saccharomyces yeast: from biocontrol strategies to reduce the use of sulfites, to sequential fermentations that lower alcohol content and enhance aromatic complexity.

With hotter growing seasons and shifting harvest windows, winemakers are increasingly challenged by high pH, low acidity, and elevated alcohol in their musts. These changes can lead to wines that feel flat, overly ripe, and microbiologically unstable, often requiring higher SOâ‚‚ doses and risking aroma loss and reduced freshness.  In this webinar, we’ll explore two innovative yeast tools designed to naturally correct these imbalances from the fermentation stage:       Excellence X-Fresh (Lachancea thermotolerans): a bio-acidifying yeast that converts sugars into lactic acid, helping to lower pH, increase total acidity, and reduce alcohol in must—while boosting microbial stability. Excellence Celsius (Saccharomyces cerevisiae): a fermentation yeast that produces elevated levels of glycerol and malic acid, enhancing mouthfeel, freshness, and aroma intensity.  Together, these strains support a balanced, sustainable winemaking strategy in the face of c
