Imperial Yeast A04 Barbarian Ale is a liquid American ale yeast selected for brewing juicy, hop-forward beers with expressive fruit character and a soft, full-bodied finish. Each pouch contains approximately 200 billion cells, providing enough yeast for a standard 5-gallon batch while delivering reliable fermentation for modern hazy and American-style ales.
A04 Barbarian Ale is formulated to produce vibrant peach and apricot esters that complement hop aroma without overwhelming the beer's balance. With attenuation of 73–74%, medium flocculation, and a recommended fermentation temperature range of 62–70°F (17–21°C), this strain creates a smooth, pillowy mouthfeel while supporting lasting haze and enhanced hop expression in juicy beer styles.
Packaged as a liquid yeast culture, A04 Barbarian 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 A04 Barbarian Ale is ideal for Hazy IPAs, American IPAs, Pale Ales, and other hop-forward American ales. Its expressive stone fruit esters, dependable attenuation, and ability to create a soft, juicy mouthfeel make it an excellent choice for homebrewers seeking modern hazy beers with bold hop aroma and balanced flavor.
