Exotics Mosaic
A Saccharomyces cerevisiae x Saccharomyces paradoxus hybrid.
A novel yeast for exotic, complex, barrel fermented iconic white and red wines.
APPLICATION
Exotics Mosaic is a hybrid between S. cerevisiae and S. paradoxus. This hybrid inherited the aromatic capabilities of both its parents, thereby expanding the aromatic potential and complexity of what pure S. cerevisiae has to offer.
White wines produced by this yeast are described as having exotic aromas and flavours. Exotics Mosaic is recommended for the production of barrel fermented Chardonnay, Chenin blanc and Viognier. It enhances guava, passion fruit, tropical fruit salad and stone fruit aromas and flavours. It is cold sensitive and ferments at a steady rate in barrels, producing good mouthfeel.
Apart from its enhanced aromatic potential in red wines, Exotics Mosaic has added advantages such as enhancing malolactic fermentation through partial malic acid breakdown (as much as 17% observed), as well as higher glycerol production and lower alcohol conversion in high sugar must conditions. Wines produced with this yeast are described as complex with intense aroma, well-rounded, well-balanced, full-bodied wines. It is recommended for the production of Syrah, Merlot and Pinotage.
