Avante Avante is a H2S-preventing red wine yeast strain that produces an intense fruit overture followed by a mild spiciness and a smooth tannin finish. Avante also imparts good mid-palate fullness with color and flavor stability across all varietals. The strain ferments at a moderate tempo and performs well in medium nitrogen musts. Renaissance Yeast’s strains have excellent fermentation kinetics, desirable sensory characteristics, and are produced to the highest quality standards. Renaissance Yeast is the exclusive developer of a novel, patented H2S-preventing technology that is the result of a natural trait in yeast that increases sulfur and nitrogen utilization efficiency during fermentation, thereby preventing hydrogen sulfide formation.
