Wyeast 1007 German Ale

Brew clean, authentic German ales with Wyeast 1007 German Ale, a premium liquid yeast strain prized for its crisp fermentation profile, broad temperature range, and excellent versatility. Originally sourced from Düsseldorf, Germany, this true top-cropping strain produces low ester levels and little to no detectable diacetyl, making it an outstanding choice for traditional German beer styles as well as clean, hop-forward ales. Each Wyeast Activator™ pack contains approximately 100 billion cells, providing enough healthy yeast to ferment a standard 5-gallon batch under appropriate conditions. Wyeast 1007 is ideal for brewing Altbier, Kölsch, Northern German Altbier, American Wheat Beer, Berliner Weisse, Bière de Garde, and Cream Ale.

Wyeast 1007 delivers a smooth, neutral fermentation that allows both malt and hop character to shine without excessive fruity esters. Fermenting toward the lower end of its recommended temperature range produces an exceptionally clean, lager-like profile, while warmer temperatures contribute mild fruitiness for added complexity. Its naturally low flocculation keeps yeast in suspension longer, promoting complete fermentation and rapid maturation, although additional settling time or filtration may be needed to achieve brilliant clarity.

This liquid ale yeast features low flocculation, 73–77% attenuation, and an alcohol tolerance of approximately 11% ABV. It performs best between 55–68°F (13–20°C) and is packaged with approximately 100 billion cells for dependable fermentation performance and consistent brewing results. Its broad fermentation range makes it well suited for both traditional German ales and clean American-style beers.

For best results, store refrigerated between 33–38°F and do not freeze. Pitch into well-oxygenated wort and ferment within the recommended temperature range. One Activator™ pack is suitable for many standard-strength 5-gallon batches, while a yeast starter is recommended for higher-gravity beers, older yeast packs, or whenever additional cell count is desired. Because this strain remains in suspension after fermentation, additional conditioning or cold crashing may help produce a brighter finished beer.

Trusted by homebrewers and professional brewers alike, Wyeast 1007 German Ale delivers dependable fermentation, clean flavor, and authentic German brewing character. Its healthy cell count, reliable performance, and versatile fermentation profile make it an outstanding choice for brewing crisp Altbiers, Kölsch-style ales, wheat beers, and other balanced beers with exceptional clarity and drinkability.
