Novonesis FrootZen TM
Specialty Yeasts For Superior Winemaking
Viniflora FrootZen is the first commercial yeast preparation based on a pure strain of Pichia kluyveri . This non- Saccharomyces yeast strain is specifically noted for its ability to enhance tropical fruit intensity and mouthfeel in white wines such as Sauvignon Blanc, Chardonnay, Riesling, and fruit forward rosé and red wines. FrootZen is an extremely powerful producer of the volatile thiol aromas 3-MHA (passion fruit) and 3-MH (grapefruit), and significantly boosts flavor compounds such as “peach, citrus and mineral”. Since its launch in 2011, it has been widely adopted into wine programs in North America, New Zealand, France, Spain and other regions known for bright, aromatic wines. Key Features: • Increased fruit flavor and complexity • Reduced risk of oxidation • Reduced risk of volatile acidity by apiculated yeast ( Hanseniaspora spp. ) • Boost indigenous Saccharomyces in non-inoculated wines Use FrootZen with your favorite Saccharomyces yeast in a sequential inoculation. Known as the “quiet fermenter”, this strain of Pichia kluyveri does not create noticeable amounts of CO2, and a treated tank will appear to be very still. However, the fermentation is still progressing as evident by the noticeable increase in fruit aromas associated with the yeast and the 1 - 3 degree drop in brix over a three-day period. This specialty yeast is not intended to achieve complete alcoholic fermentation but to enhance wine complexity. After FrootZen has done its job, inoculate with your Saccharomyces strain of choice to complete fermentation. FrootZen is a direct-inoculation yeast, and no rehydration step is needed. Add directly to harvested grapes, crushed grapes, or must.
Novonesis has led the development of non- Saccharomyces yeast strains for over a decade and offers pure strains of three varieties of non- Saccharomyces yeast as well as a mixed culture preparation which provides the impact of non- Saccharomyces along with the ability of Saccharomyces to complete alcoholic fermentation with a single inoculation.
