JY322 - North Yorkshire

JY322 is a quintessential North-Yorkshire ale yeast strain. JY322 produces moderate esters and nutty undertones, paired with a restrained sulfur note that dissipates during conditioning, enhancing malt and hop character. Its preference for high-mineral worts accentuates a robust malt backbone, making it ideal for Ordinary Bitters, Best Bitters, and Yorkshire-style Pale Ales. With medium flocculation, JY322 forms a thick, creamy head during fermentation, often requiring rousing or antifoam to manage vigorous krausen, and settles into a moderate sediment for a clear yet flavorful beer. Light phenolic flavors may emerge (the strain is lightly POF+), adding a hint of spice to the finish. 

This is an heritage English strain. It is a very strong krausen producer, and needs high-mineral wort to finish. Lightly phenolic. Does not do well in high gravity worts, stay traditional.
