Viniflora® Concerto™ Yeast Viniflora® Concerto™ is a pure strain of Lachancea thermotolerans to be used in combination with your Saccharomyces cerevisiae strain of choice. This non-Saccharomyces yeast strain has been carefully selected to mimic successful wild ferments, increase aromatic complexity, enhance fresh fruit forward wines, and develop a round mouthfeel. This is particularly recommended for white and red wines from warmer climates. This specialty yeast is not intended to achieve complete alcoholic fermentation but to enhance wine complexity. Concerto has to be followed by a Saccharomyces cerevisiae yeast of choice to achieve a safe and fast alcoholic fermentation.
