S. cerevisiae • cerevisiae Acid Preservation Malbec, Petit Sirah, Sangiovese, Syrah, Tempranillo, Cabernet Sauvignon, Merlot, Petit Verdot 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 up to 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 to 15 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. Storage Store at 4°C(39°F). Use immediately once opened. Note: IONYSWF is an innovative yeast selection and is protected by an International Patent pending; No WO2015/11411. Propagation of IONYSWF is an infringement of this Patent.
