Wyeast | 3864 Canadian/Belgian Ale Yeast (Private Collection)

This alcohol-tolerant strain produces complex and well-balanced Belgian Abbey-style ales. Banana and fruit esters are complemented nicely with mild levels of phenolics and hints of acidity. Ester levels may be elevated by increasing gravity and fermentation temperatures. This Wyeast yeast strain has been classified as Saccharomyces cerevisiae var. diastaticus using rapid PCR analysis. This strain carries the STA1 gene, which is the “signature” gene of Saccharomyces cerevisiae var. diastaticus and will be found in all diastaticus strains.
