IonysWF™ is the result of a multi-year research project between Lallemand and INRA Montpellier. Selected for its ability to significantly retain must/juice acidity during fermentation, IonysWF is recommended for fermenting reds from warmer climates with high pH and high potential alcohol. The acidification ‘power’ of IonysWF may result in a total acidity difference of +0.4 – 1.4 g/L tartaric acid and a pH decrease of between 0.04–0.2.

Low producer of VA, SO2 and H2S, with an alcohol tolerance of upto 16% (v/v). IonysWF has very high nitrogen requirements and a balanced nutrient protocol is essential. Maintaining a temperature range of 25–28°C(77–82°F) optimizes glycerol production (up to15 g/L) and may decrease alcohol production between 0.4–0.8%. IonysWF has a moderate fermentation speed with a long, but steady stationary phase.

With proper nutrition and temperature control, wines made with IonysWF are characterized as having fresh fruit and mineral characters and fine-grain tannins.

NOTE: Must be refrigerated.
