Imperial Yeast A07 Flagship Ale is a liquid American ale yeast selected for brewing clean, balanced beers with a crisp finish and dependable fermentation performance. Each pouch contains approximately 200 billion cells, providing enough yeast for a standard 5-gallon batch while producing a neutral fermentation profile that allows both hop and malt character to stand out. A07 Flagship Ale is formulated to produce low ester character and a dry, refreshing finish across a wide range of American beer styles. With attenuation of 73–77%, low-to-medium flocculation, a recommended fermentation temperature range of 60–72°F (16–22°C), and alcohol tolerance up to 12% ABV, this strain delivers consistent performance and excellent balance for both hop-forward and malt-driven recipes. Packaged as a liquid yeast culture, A07 Flagship Ale should be stored refrigerated between 33–38°F (1–3°C) and should not be frozen. Pitch into properly oxygenated wort and ferment within the recommended temperature range for optimal performance. Use within the manufacturer's recommended freshness window, and consider preparing a starter when brewing higher-gravity beers or using older yeast. Imperial Yeast A07 Flagship Ale is ideal for American IPAs, Pale Ales, Stouts, and a wide variety of other American-style ales. Its clean fermentation profile, dependable attenuation, and broad versatility make it an excellent choice for homebrewers seeking consistent results and balanced flavor across multiple beer styles.
