When it comes to brewing an American lager, choosing the right dry yeast is crucial for achieving the desired flavor profile and characteristics. While there are several options available, two popular choices for American lagers are Saflager S-23 and W-34/70.
Saflager S-23 is a widely used dry yeast that has gained popularity among homebrewers for brewing American lagers. It is known for its ability to produce clean and crisp flavors, which are essential for this beer style. S-23 ferments relatively quickly and has a relatively high attenuation, resulting in a well-attenuated beer with a dry finish. It also has a high tolerance for low temperatures, making it suitable for lager fermentation.
On the other hand, W-34/70 is another dry yeast option that is highly regarded for brewing American lagers. This yeast strain is derived from the famous Weihenstephan yeast, which is used by many commercial breweries. W-34/70 is known for producing a clean and neutral flavor profile, allowing the malt and hops to shine through. It also ferments well at low temperatures and has a high flocculation rate, resulting in clear and bright beers.
Both Saflager S-23 and W-34/70 can produce excellent American lagers, but there are slight differences between the two. S-23 tends to have a slightly fruitier ester profile compared to W-34/70, which can add a touch of complexity to the beer. However, some brewers prefer the cleaner and more neutral characteristics of W-34/70 for American lagers.
Ultimately, the choice between Saflager S-23 and W-34/70 comes down to personal preference and the specific flavor profile you want to achieve in your American lager. It can be helpful to experiment with both strains to determine which one best suits your brewing style and taste preferences.
In addition to these dry yeast options, there are also liquid yeast strains available for brewing American lagers. Some popular choices include Wyeast American Lager (2035), Wyeast Pilsen Lager (2007), White Labs American Pilsner (WLP840), and White Labs Pilsner Lager (WLP800). These liquid yeast strains offer a wider range of flavor profiles and characteristics, allowing for more customization in your American lager recipe.
The best dry yeast for American lagers can vary depending on personal preference and the specific flavor profile desired. Saflager S-23 and W-34/70 are both excellent choices, each with its own unique characteristics. Ultimately, it's important to experiment and find the yeast strain that best suits your brewing style and taste preferences.
