What is the difference between lager and ale

Yes, the discovery of the New World and the establishment of trans-Atlantic trade happened at the same time. While nobody actually knows how S. There, S. Which then, via trade or early corporate espionage, traveled to breweries across continental Europe and beyond. And, like ale yeast, each time S.

What about poor, demoted S. Well, the researchers figured out that this strain actually arose when the newly minted S. So, S. Biology and brewing are both messy practices that frequently produce something entirely unexpected.

In the case of all of those cold-tolerant S. While there is so much to talk about regarding yeast, the biggest difference between lager and ale yeast their fermentation process.

Top fermenting yeast is used in brewing ales. This type of yeast, also known as Saccharomyces cerevisia , has many common applications from beer and winemaking to making bread. This hardier variety of yeast is referred to as top-fermenting because it will rise to the top during fermentation and sink to the bottom of the brewing vessel when the fermentation process is ending. This fast-acting yeast brews beer in as little as a week and leaves yeast particles floating to the top due to the increased motion of yeast in the fermentation vessel.

Bottom fermenting yeast that is used in brewing lagers, is also known as, Saccharomyces uvarum. This yeast doesn't necessarily ferment at the bottom but it doesn't rise up during fermentation like top-fermenting yeast. Since the yeast isn't seen during the fermentation process, it is called a bottom-fermenting yeast. This type of yeast is more delicate than top-fermenting yeast and requires specific conditions to thrive, which means it can produce more outcomes than ale yeast.

This type of yeast is cold tolerant, which means they can be active at low temperatures. This yeast also consumes sugars slower and in turn, has a slower fermentation process. Additionally, it has a lower tolerance to alcohol and it can ferment mebliose, a sugar not fermented by top-fermenting yeasts.

This features of this yeast allow more sugar to linger in the finished beer, creating a smoother and sweeter beer. What is just as important as the taste of a beer? The alcohol content. Yeast plays a very large role in the alcohol content of a beer because their ability to thrive in high versus low alcohol environments determines the alcohol content of the beer.

Ale yeasts can survive in high concentrations of alcohol, therefore, the resulting beer has a higher alcohol content. The more fragile and slower lager yeast can't survive in high alcohol environments making lager beers lower in overall alcohol content. Even well-intentioned food journalists often make this mistake! Now take this as an excuse to go hit up your favorite local beer bar or shop and do some homework.

Skip to main content Drink. Lager is my favorite style of beer. What can you tell me about it? Alright, fancy beer man! Give me a one word answer on how lagers and ales are different. What about alcohol content? I've heard lagers are way lighter.
