The main difference between high and low fermentation beer is the yeast used in the process. Yeast is a microorganism that is responsible for converting sugar into alcohol during the fermentation process. High fermentation beer is made with a type of yeast called top-fermenting yeast, while low fermentation beer is made with a type of yeast called bottom-fermenting yeast. Let us take a closer look at each of these types of beer.
High Fermentation Beer
High fermentation beer is also known as ale. This type of beer is made using a yeast strain that ferments at higher temperatures between 20 to 25 degrees Celsius. The yeast floats on top of the beer during fermentation, hence the name top-fermenting yeast. Top-fermenting yeast produces a complex range of fruity, spicy, and earthy flavors, giving high fermentation beer a unique flavor profile.
High fermentation beer has a shorter fermentation time, usually between one to two weeks. Ales tend to be more full-bodied and have a higher alcohol percentage, typically between 4 and 10 percent. Some of the popular high fermentation beer styles include IPA, Stout, Porter, and Belgian ale.
Low Fermentation Beer
Low fermentation beer is also known as lager. This type of beer is made using a yeast strain that ferments at lower temperatures between 7 to 15 degrees Celsius. The yeast sinks to the bottom of the beer during fermentation, hence the name bottom-fermenting yeast. Bottom-fermenting yeast produces fewer flavors during fermentation, resulting in a cleaner, crisper taste.
Low fermentation beer has a longer fermentation time, usually between two to four weeks. Lagers tend to be lighter in body and have a lower alcohol percentage, typically between 3 and 6 percent. Some of the popular low fermentation beer styles include Pilsner, Vienna Lager, Dunkel, and Märzen.
Which is better?
There is no winner when it comes to high versus low fermentation beer. It all comes down to personal preference and taste. Some people prefer the complex flavor and aroma of high fermentation beer, while others enjoy the clean and crisp taste of low fermentation beer.
However, it is worth noting that high fermentation beer tends to be more flavorful and has a higher alcohol percentage. As a result, it is often more expensive than low fermentation beer. Additionally, high fermentation beer is often served at warmer temperatures, allowing for the flavors and aromas to be fully appreciated.
Conclusion
In conclusion, beer can be classified into two main categories – high and low fermentation beer. High fermentation beer is made with top-fermenting yeast and tends to be more full-bodied with a higher alcohol percentage. Low fermentation beer is made with bottom-fermenting yeast and tends to be lighter in body with a lower alcohol percentage. There is no better beer between the two; it all comes down to personal preference. Whether you prefer ales or lagers, one thing is for sure, beer is a timeless beverage that will continue to be appreciated for generations to come.
