Natural cross hybrid for aromatic whites and rosés

Cross Evolution® is a strong fermenting yeast, from the Institute for Wine Biotechnology at the University of Stellenbosch in South Africa, that is ideal for aromatic white and rosé wines with high alcohol potential, low fermentation temperatures, and low nitrogen levels. Cross Evolution is not a genetically modified yeast but a result of a unique breeding program resulting in hybrids. Cross Evolution® also contributes an increased mouthfeel component resulting in aromatic wines with balanced mouthfeel. Cross Evolution® is recommended for Chardonnay, Chenin blanc, Gewürztraminer, Pinot blanc, Pinot gris, Riesling, Roussanne, Sauvignon blanc and Viognier.
