JY320 - South London

JY320 is a refined southern English ale yeast strain. Good for classic Best Bitters and Strong Ales, this strain follows a slow fermentation that enhances malt complexity and hop balance. JY320 produces moderate esters, imparting a mild stone fruit character, with a faint herbal note.  Thriving in high-mineral worts, JY320 yields a polished beer with minimal sulfur, while its moderate flocculation creates a light fermentation head and settles into a compact sediment, resulting in a clear, refined pint. 

This heritage strain is a slow fermenter (7-14 days) and needs high-mineral worts to complete fermentation. It can handle higher alcohol levels better than other heritage English strains.
