Ice Packs / Shipping:For best results, we strongly recommend adding an ice pack to your liquid yeast order. Ice packs do not guarantee that yeast will arrive cold, but will keep yeast colder for longer during transit. We can not replace yeast that arrives warm. In warm weather months, we highly encourage choosing dry yeast. Liquid yeast is final sale. As a live, perishable ingredient that requires refrigeration, we are unable to accept returns or exchanges once an order has left our warehouse.

Storage: Store in the fridge (33–38ºF). Do not freeze. Pitch cold - do not warm to room temp prior to pitching. Use within 4 months for direct pitching. For pouches older than 4 months, or that are warm, use a yeast starter to boost cell count.

Fermentation Temp Range
Each yeast strain has a temperature range where it performs best. Lagers require cooler temps, while Kveik yeasts can ferment in extreme heat. Maintaining the proper fermentation temperature for each yeast strain is crucial its health. Matching a yeast's ideal range to your environment (or your ability to control temp) is key to getting clean, consistent results.

Wyeast 1007 German Ale is the go-to strain for brewing Kölsch, Altbier, and other clean German-style ales that benefit from a restrained, lager-like fermentation character. Its low ester production keeps the profile crisp and grain-forward.

It also performs well in Berliner Weisse, American wheat beers, Bière de Garde, and a wide range of Belgian and specialty ales where a clean fermentation canvas is desired. Its broad temperature tolerance (55–68°F) gives brewers flexibility to adjust character by fermentation temperature.

Wyeast 1007 excels in clean, lager-like ale styles.

Primary: Kölsch, Altbier, Berliner Weisse, American Wheat Beer
Also works for: Bière de Garde, Wheatwine, International Amber Lager, Belgian Styles, Specialty Ales, Historical Beer styles

• Store refrigerated at 33–38°F
• Do not freeze
• Pitch into well-oxygenated wort
• Ferment between 55–68°F (13–20°C)
• Cooler temps produce a cleaner, more lager-like profile
• Plan for additional conditioning time — this powdery strain stays in suspension post-fermentation
• Low to no diacetyl production; a brief diacetyl rest is still good practice
• Each pack contains approximately 100 billion cells

Frequently Asked Questions

Wyeast 1007 produces a very clean, low-ester profile with lager-like crispness. Fermentation at higher temperatures within its range may produce mild fruitiness. Low to no detectable diacetyl.

Kölsch, Altbier, Berliner Weisse, and American Wheat Beer are primary uses. It also works well in Bière de Garde, Wheatwine, International Amber Lager, and a variety of Belgian and specialty ale styles.

Wyeast 1007 is a powdery strain that remains in suspension after fermentation rather than settling to the bottom. This is normal. Additional cold conditioning time or cold crashing will help achieve clarity.

Ferment between 55–68°F (13–20°C). Cooler temperatures produce a cleaner, more lager-like character. Warmer temperatures toward the top of the range may introduce mild fruitiness.

For standard gravity 5-gallon batches a starter is generally not required. For higher gravity beers or older packs, a starter is recommended to ensure vigorous, healthy fermentation.
