Omega Yeast OYL-044 Kölsch II is a liquid ale yeast that produces clean, crisp beers with a bright lager-like finish and subtle fruit character. Each 150 mL pouch contains approximately 225 billion cells, providing enough yeast for a standard 5-gallon batch while delivering balanced fermentation and excellent clarity for Kölsch-style and hybrid ales.
OYL-044 is designed to produce restrained fruit esters with a smooth, refreshing finish that highlights both malt and hop character. With attenuation of 72–78% and a fermentation temperature range of 65–69°F (18–21°C), this strain ferments cleanly while developing the subtle complexity expected in traditional Kölsch-style beers. A light sulfur character may be present during active fermentation but dissipates naturally during conditioning, leaving a polished final beer.
Packaged as a liquid yeast culture, OYL-044 should be stored refrigerated between 33–38°F (1–3°C) and should not be frozen. Pitch cold into properly oxygenated wort and ferment within the recommended temperature range for best performance. Use within four months for optimal viability, and consider preparing a starter for older pouches or higher-gravity beers.
Omega Yeast OYL-044 Kölsch II is ideal for Kölsch, cream ales, hoppy lagers, and other clean, refreshing ale styles. Its crisp fermentation profile, reliable attenuation, and ability to bridge classic ale and lager characteristics make it an excellent choice for homebrewers seeking bright, balanced beers with exceptional drinkability.
