Description
A German weizen strain in the same family as JY214 but quieter on isoamyl acetate, so the banana stays in check even at the warm end of its range. Clove and banana land in balance around the high teens Celsius, giving a lively but composed hefeweizen fermentation. Stocked originally for a local brewer with decades of pub-brewing behind him.
