New Lallemand Catalogue 2019 / 2020

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

IONYS HRThe new wine yeast IONYS™ is 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.

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.
