OYL-001 Alt

Product Description:

This Düsseldorf-style ale yeast is a highly vigorous top-cropping yeast strain known for its clean fermentation profile and fast turnaround. It performs exceptionally well at lower fermentation temperatures, producing a crisp, low-ester beer ideal for Kölsch-style ales, altbier, and other clean German or hybrid ales. When fermented warmer, subtle light fruit esters may develop without overpowering the beer.

This yeast features quick maturation, remains naturally in suspension, and produces little to no diacetyl, resulting in bright, clean finishes with minimal conditioning time. A great choice for brewers seeking reliable performance, clean flavor expression, and efficient fermentation. For similar fermentation characteristics, consider Kölsch II (OYL-044) or West Coast Ale I (OYL-004).
