Style Guide: Tips On How To Brew A Kölsch

Kolsch BeerCrystal clear, the color of golden straw, a Kölsch is yet another excellent beer for summer drinking. With that in mind, here is a Kölsch profile overview along with some Kölsch brewing tips.

Kölsch is an ale style native to Köln, Germany, known to us Americans as Cologne. Technically, only beers brewed in Cologne may be called Kölsch (but I don’t think anyone will prosecute if you do!).

Kölsches are similar to light lagers in that they’re clean, crisp, and refreshing, however they typically have a more pronounced, moderate hoppiness than light lagers. They are also distinguished by a somewhat fruity yeast character and a distinctively dry finish.

Kölsch beers use very light malts, such as Pilsner or Two-Row, to achieve their pale color. They may contain a small proportion of wheat malt, usually around 10-20% of the total grain bill.

When it comes to hops, Kölsch beers have a few more IBUs than the standard light lager. The BJCP guidelines call for 20-30 IBUs, with most of the hops added early in the boil. To be authentic, a Kölsch should use German noble hops, specifically Spalt, Saaz, Tettnang, or Hallertau.

Though the Kölsches are typically brewed with top-fermenting ale yeasts, they are fermented at a cooler temperature, say 55°F to 65°F, and usually go through a lagering period at even colder temperatures. This blend between an ale and a lager makes a Kölsch recipe an excellent “entry-level” beer for drinkers making the transition from macro lagers into more adventurous craft beer styles.

 

Kölsch Brewing Tips:

  • For the grain bill, starting with enough Pilsner or Two-Row malt to achieve an original gravity of about 1.047. Vienna malt is a suitable alternative. Use up to 1-2 lbs. of wheat malt if desired.Shop Steam Freak Kits
  • When brewing a Kölsch extract recipe use a very pale malt extract, such as Stream Freak Light LME or Light DME, and may wish to use some Pilsner and/or wheat malt for a mini-mash to add some malty, grainy flavor.
  • When making a Kölsch beer yeast selection is important. The Kölsch yeast strain is ideal, but lager yeasts and other German ale yeasts can be used as well.
  • To achieve a dry finish, a highly attenuating yeast should be used. Mashing around 148°-150°F should produce a more fermentable wort, resulting in a lower final gravity and less residual sweetness.
  • A key factor in creating an authentic Kölsch is to ferment it at fairly low temperatures. Primary fermentation should be around 55°-65°F, and secondary fermentation around 40°-50°F. These lower fermentation temperatures may mean that fermentation takes longer than it does for a typical ale.
