This strain is a classic, true top cropping yeast strain from a traditional brewery in Cologne, Germany. Beers will exhibit some of the fruity character of an ale, with a clean lager like profile. It produces low or no detectable levels of diacetyl. This yeast may also be used to produce quick-conditioning pseudo-lager beers and ferments well at cold 55-60°F (13-16°C) range. This powdery strain results in yeast that remain in suspension post fermentation. It requires filtration or additional settling time to produce bright beers.

For best results we always recommend ordering an ice pack with your liquid yeast.

Please Note: When choosing an ice pack option beware that the liquid yeast will not arrive cold even when shipped together. Ice packs and insulated mailing options are designed to keep the yeast colder for longer during shipment, but they will not ensure that your yeast arrives cold. We will not replace liquid yeast that arrives warm. During warmer months we strongly recommend you choose dry yeast.
