American-style beers tend to express minimal yeast flavor and highlight the combination of malt and hop aroma. Typical American ale yeast strains are very clean and neutral, producing subtle esters. Like the profile of the classic American pale ale, Sierra Nevada Pale Ale, the flavor profile of these beers is an expression of hops and malt.
There are many brewing yeast strains in both liquid and dry forms all over the world for different styles of beer. For brewing American ale, you need a yeast that produces a clean, neutral, and crisp flavor and low fruity esters. Angel Yeast’s American Ale Yeast A01 is one of the most common dry yeasts available for brewing an American ale with that clean and neutral flavor and medium to high attenuation.
A01 is a strain of Chico or California ale yeast. As an active dry yeast, A01 is easy to use and transport. It is simpler to use than liquid yeast. You can pitch it directly into a low-gravity wort without rehydrating it. However, for higher-gravity wort, we recommend rehydrating it first to bypass a short lag time.
Versatility and Quality
American Ale Yeast A01 is widely adaptable for many kinds of American beers that highlight the characteristics and style of malt and hops. It is great for all kinds of American-style ales, but it can also be used in brown, amber, IPA, imperial IPA, stout, wheat, and porters. When you want to promote the malt and hop character, you can pitch A01 to make a hoppier beer.
Developed by Angel Yeast’s team of expert biochemists and fermentation specialists, American Ale Yeast A01 embodies years of meticulous research and development. Derived from carefully selected yeast strains, A01 is tailored to meet the demands of modern brewers seeking excellence in crafting American-style ales.
Versatility is the hallmark of American Ale Yeast A01, offering brewers a canvas to express their creativity across a spectrum of beer styles. Whether you’re brewing a classic pale ale with a crisp bitterness, a bold IPA bursting with tropical hop aromas, or a rich amber ale with caramel malt sweetness, A01 rises to the occasion, delivering consistent and reliable performance batch after batch.
Angel Yeast’s unwavering commitment to quality assurance ensures that every batch of American Ale Yeast A01 meets the highest standards of excellence. Rigorous quality-control measures, stringent purity standards, and advanced fermentation technologies guarantee product consistency and reliability, empowering brewers to produce exceptional beers with confidence.
Brewing Properties
Apparent Attenuation: Attenuation represents the percentage of sugar that is converted into alcohol during the beer fermentation process. Apparent attenuation of A01 is about 75–83 percent, resulting a drier and less sweet beer.
Temperature Range: 59–77°F (15–25℃)
Phenolic off-flavor (POF) Phenotype: Negative
Diastaticus: Negative
Alcohol tolerance: 10% (v/v)
Flocculation: Medium
Ester Profile: Esters are fruity flavor and aroma compounds in beers. For American ales, fruity esters should be low to moderate. As a neutral beer yeast, A01 produces low esters, leading to clean, crisp American-style beers, which combine malt and hops for a refreshing and flavorful result. A01 produces fewer fruity esters than other ale strains, resulting in clean and crisp beer and allowing malt and hops to highlight the finished beer.
Cheers to the Craft
As we look to the future, the potential for American Ale Yeast A01 knows no bounds. Angel Yeast aims to elevate A01 to new heights, captivating brewers worldwide and inspiring a renaissance in American ale brewing.
