JY87 is a Saccharomyces yeast with an almost Brett-like character isolated by jasperyeast LLC.   Shows great fermentation as primary strain in a variety of beers. Ferments fast to 60% attenuation, after which fermentation slows down and more flavor and aroma is produced. Strong pineapple and stonefruit aroma after prolonged fermentations (3-9 months). Great companion to beers that could use some funk, and complements hoppy beers perfectly. Flocculation is low, strain can form a pellicle when oxygen is present.
