Description
A German ale strain built for Altbier and the cool-fermented German ale family. It finishes dry and crisp with restrained fruit esters over a smooth malt base, giving a lager-like impression from an ale fermentation. Moderate flocculation and a narrow cool temperature band mean it wants steady temperature control.
