More acidity, more balance with the new IONYS™ wine yeast

The new wine yeast IONYSis the first wine yeast that has been selected within the Saccharomyces cerevisiæ species for its capacity to significantly and naturally acidify must during fermentation and have a lower sugar to alcohol conversion ratio.  It is an ideal yeast for red wine and to tackle the problem of wines affected by global warming.

MLF Bacteria – Efficient Contributors to Winestyle

The effects of malolactic fermentation (MLF) on wine aroma and chemical properties of Australian Cabernet Sauvignon were explored at the AWRI , by inoculation with different selected Oenococcus oeni. Significant compositional differences occurred in response to the different MLF treatments and strain dependent changes in volatile aroma compounds were observed. Increases in fruity esters were associated with increases in fruit related sensory attributes. These trends were observed over three vintages in Cabernet Sauvignon fruit sourced from various vineyards. _BACTERIA - 120410_MLB_Contributers to wine style

YSEO process: a unique yeast production process

Lallemand has developed a unique yeast production process called YSEO® (Yeast Security and Sensory Optimization). This process increases fermentation reliability and security and ensures fewer organoleptic deviations, but not all yeast can be prepared by this process. The process (when compared to non YSEO®):
  • Improves the yeast cells assimilation of essential micronutrients and vitamins.
  • Improves the yeasts ability to implant in the must for a more reliable fermentation.
  • Linked to a reduction in yeast stress thereby reducing H2S, VA and SO2 production.
  • Shorter lag phase.
  • Improves the resistance and adaption of the yeast under difficult fermentation conditions.
