The Perfect Yeast for Mexican Lagers

When it comes to a traditional Mexican , one of the key factors that contribute to its unique flavor and character is the choice of . Selecting the right yeast strain is crucial in achieving the crisp, clean, and refreshing taste that Mexican lagers are known for.

While there are various yeast strains available in the market, there are a few specific options that work exceptionally well for brewing Mexican Lagers. In this article, we will explore the characteristics of these yeasts and discuss how they can enhance your brewing process.

1. Wyeast 2278 (Czech Pils):
Wyeast 2278, also known as Czech Pils yeast, is an excellent choice for brewing Mexican Lagers. This yeast strain ferments at cooler temperatures (around 50-55°F) and produces a clean and crisp with a mild fruitiness. It imparts a subtle maltiness to the beer, which complements the traditional Mexican Lager style.

2. WLP001/Wyeast 1056 (American ):
If you can't get your hands on Wyeast 2278, don't worry! Another viable option is using WLP001 or Wyeast 1056, both of which are American Ale yeasts. Although these yeasts are typically used for brewing ales, they can also be used to ferment Mexican Lagers at the same temperature range as Wyeast 2278. These yeasts will produce a clean and bright beer with minimal ester production, making them suitable for brewing Mexican Lagers.

It's important to note that Mexican Vienna Lagers tend to be slightly darker and sweeter than their Austrian counterparts. To achieve this, Mexican brewers often add Munich and Crystal malts, as well as flaked corn, to lighten the body. However, using Vienna remains the traditional approach for brewing Mexican Lagers.

When it comes to fermentation, it's crucial to maintain a consistent temperature within the recommended range. This will ensure optimal yeast activity and flavor development. Mexican Lagers typically ferment for a longer period at cooler temperatures, allowing the yeast to work slowly and produce a clean and well-rounded beer.

Selecting the right yeast strain is essential for brewing authentic Mexican Lagers. While Wyeast 2278 (Czech Pils) is the ideal choice, WLP001 or Wyeast 1056 (American Ale) can also produce excellent results. Whichever yeast strain you choose, remember to ferment at the appropriate temperature range and consider adding Munich and Crystal malts or flaked corn to achieve the desired sweetness and body.

So, go ahead and experiment with these yeast strains to create your own flavorful and refreshing Mexican Lager. Cheers to brewing success!

What Yeast Is Best For Lager?

When it comes to choosing the best yeast for lagers, there are several options available. Lager yeast is known for its ability to ferment at cooler temperatures and produce clean, crisp flavors. Here are some popular choices:

1. Safale K-97: This strain of Saccharomyces cerevisiae is often used in brewing Kolsch and pseudo lagers. It can tolerate cooler fermentation temperatures and produces a clean, crisp profile.

2. Lallemand Nottingham: Another strain of Saccharomyces cerevisiae, Nottingham is versatile and can be used for brewing Kolsch and pseudo lagers. It produces a clean, neutral flavor profile and is known for its ability to ferment at a wide range of temperatures.

3. Skare: Skare yeast is highly regarded for its clean and crisp fermentation profile, making it suitable for all types of lagers. It produces a well-balanced flavor and is often used in commercial brewing.

4. Opshaug: Opshaug yeast, also a strain of Saccharomyces cerevisiae, is known for its clean fermentation characteristics. It can ferment faster at higher temperatures, which can be beneficial for brewers looking to speed up the fermentation process.

These are just a few examples of yeast strains that are commonly used for brewing lagers. Each strain has its own unique characteristics and flavor profiles, so it's important to consider the specific requirements of your recipe and desired outcome when choosing the best yeast for your lager.

What Temperature Do You Ferment Mexican Lager Yeast?

Mexican lager yeast typically ferments best within a temperature range of 50 to 55 degrees Fahrenheit (10 to 13 degrees Celsius). This particular yeast strain, commonly referred to by its SKU YP940, is known for its ability to produce clean and crisp flavors when fermented within this temperature range. It is important to note that fermenting outside of this temperature range may result in undesirable flavors or incomplete fermentation.

Key details about fermenting Mexican lager yeast:

– SKU: YP940
– Minimum attenuation: 70
– Maximum attenuation: 80
– Recommended minimum fermenting temperature: 50°F (10°C)
– Recommended maximum fermenting temperature: 55°F (13°C)

To ensure optimal results, it is crucial to monitor and control the fermentation temperature within this specific range. Deviating too far from these temperatures may lead to off-flavors or other fermentation issues. It is also worth mentioning that different yeast strains may have different temperature requirements, so it is always advisable to refer to the specific instructions provided by the yeast manufacturer.

Fermenting Mexican lager yeast, such as the one with SKU YP940, is best done within a temperature range of 50 to 55 degrees Fahrenheit (10 to 13 degrees Celsius). This will help achieve the desired clean and crisp flavors associated with Mexican lagers.


When it comes to choosing the right yeast for brewing a Mexican lager, it is important to consider the desired characteristics of the final beer. While traditional Austrian lagers typically use a lager yeast, Mexican brewers often opt for a slightly different approach.

Mexican Vienna Lagers tend to be a bit darker and sweeter, with the addition of Munich and Crystal malt and flaked corn to lighten the body. This means that the choice of yeast becomes crucial in achieving the desired flavor profile.

While Wyeast 2124 (Bohemian Lager) is a popular choice for brewing traditional lagers, I recommend using Wyeast 2278 (Czech Pils) if available, or WLP001/Wyeast 1056 (American Ale) as alternatives. These yeast strains will provide a crisp, bright, and clean taste to the beer, which is essential for a Mexican lager. Additionally, at the temperature range we are fermenting, there is no significant risk of noticeable esters even with the ale yeast.

It is worth noting that lager yeast, such as Safale K-97 or Lallemand Nottingham, can also be used for brewing pseudo lagers or Kolsch-style beers. These yeast strains offer a clean and crisp flavor profile, making them suitable for a range of lagers.

Ultimately, the choice of yeast for a Mexican lager depends on personal preference and the desired characteristics of the beer. By considering the specific flavors and qualities you want to achieve, you can select the right yeast to create a delicious and authentic Mexican lager.
