Wait, what’s the difference between lagers and ales? The crafty truth behind the two beer types that started it all

Often asked among new-to-the-scene beer drinkers are the age-old questions like: How can I differentiate between ales and lagers? How do I know which one I’m drinking?

Have no fear, District Brewing Company is here to help you, once and for all, become an expert in what qualities differentiate the two major beer styles that have defined the beer industry since the Middle Ages. Even those who know their way around a lager versus an ale may learn a thing or two about the beer styles they enjoy in this helpful guide.

When it comes down to it, the primary distinctions between ales and lagers are in their looks, taste and yeast fermentation characteristics.

Ales tend to be:

  • Darker and cloudier in color
  • Robust in flavor and smell
  • Hop and malt notes more prominent
  • Often contain bitter tones
  • Are stronger in alcohol content. This is because the nature of the yeast used to make ales has a higher tolerance for alcohol composition.

Ales are brewed with what is known as a top fermenting yeast. This yeast is the same strain that has been used over centuries around the world to make bread and various wines, called Saccharomyces cerevisiae. This yeast brews under warmer conditions (generally between 16-24 degrees Celsius and up to 38) and quicker than lagers. Brew times are often as short as a week whereas lagers can take months. During the fermentation process, the beer acquires a cloudy appearance and a fluffy crown of fermentation bi-product floats to the top of the barrel.

According to Popular Science, strains of ale yeast and strains of lager yeast—originating from the forests of Patagonia in Argentina—cross-contaminated at some point during historic trade and exploration to form the distinct lager yeast. As such, lagers are newer to the brewing scene as they are an adaptation from the ale yeast.

Lagers tend to be:

  • Sweeter, crisp,’ cleaner’ tasting, and generally higher in sugar content
  • Well-balanced, mellow flavor
  • Emanate a heavier yeast smell during the fermentation process
  • Lighter in color, clearer in body
  • Less bitter, higher carbonation than ales

Lagers were a Middle Age revelation by Bavarian brewers who discovered that their beer continued to ferment even during the winter months. The strain of yeast they came across was somehow able to withstand the cold temperatures, yet elongated the overall fermenting process. Today brewing of lagers requires an additional step of cold conditioning where the beer is ‘lagered’ or stored for a period of weeks.

This strain known as saccharomyces pastorianus brews best under cold conditions (generally between 7-13 Celsius) and is a much slower process. Unlike ales, lager yeast doesn’t float to the top of the vessel during the fermentation process—thus giving it the common denotation of being “bottom fermenting” yeast. The process of fermenting under cold conditions suppresses the many bi-products of yeast allowing for a reduction of high hops and malt levels; this in turn provides a more refined and “cleaner tasting” beer—a characteristic of many lagers.

This cold-intensive process also inhibits the lager yeast’s ability to sporulate—or form a protective wall from the cold. This inability results in lagers having a lower alcohol tolerance compared to ales. Lager yeast is able to ferment the type of sugar melibiose which ale yeast is unable to.

Here’s a list of the common styles of ales and lagers you’ll find being batched in your local brewing establishment. Here at District, we offer a variety of styles to cover all tastes.

Common ale styles:

  • Brown ale—nutty, sweet and smooth with subtle hops
  • Pale ale—pale in color with a balanced sweet maltiness and bitter hops profile
  • India pale ale—heavily hopped pale ale, generally with higher alcohol content
  • Blonde ale—most similar to a lager in its light body and flavor; mildly sweet and often has a biscuity flavor
  • Barley Wine—very high in ABV and aged over time much like wine, with the base of a grain rather than a fruit; intense and complex notes of fruit and hops; color ranges from amber to dark brown
  • Imperial IPA—bold, strong, very hoppy and high in alcohol content; sweet or bready malt flavors balance the hops used
  • Porter—dark brown or black in appearance and marked by chocolatey notes; generally dry and hoppy with less malty sweetness
  • Stout—marked by roasting flavors like coffee, chocolate and barley, molasses or licorice; can be sweet or dry; appear dark brown or black and opaque; pour with a thick, creamy head
  • Wheat ale—often contain spices or fruit notes; lighter-wheat color and cloudy in appearance, heavy yeast flavor and subtle spice notes

Common lager styles:

  • German Pilsner—pale gold/straw colored with subtle hop notes and malted barley flavors; tend to be drier and more bitter; light grain taste, and can feature a floral aroma
  • Pale Lager—widely popular around the world; known for being aromatic, crip, malty and slightly hoppy; light straw in color due to using rice or corn in the brewing process; very little hoppines and malt; high levels of carbonation
  • Bavarian Dark Lager (Dunkel style)—dark brown with a red tint, malt forward and moderately sweet with notes of chocolate, nuts, caramel and breadiness; tend to taste yeasty, earthy; low hops
  • German Schwarzbier (Dark lager)—dark beer but light in flavor profile, prominent roasted malt flavors but not overpowering; slightly sweet and balanced, and drier than the Dunkel style
  • German Style Bock—strong, malty, sweet beer; copper/amber in color and often characterized by toasty flavors
  • Doppelbock—fuller-bodied and stronger than the traditional bock with a higher alcohol content; dark in color, light on the hops and bitterness
  • Marzen—malt forward, amber in color, dry on finish; traditionally brewed in March (Marz) at the end of the brewing season, and stored in caves and served in autumn; official Oktoberfest style Find this fascinating? Check out this page for a profile breakdown of all your favorite styles of beer.
