Once the calendar turns to September, we all think about Oktoberfest beers. The style is called Märzen or Märzenbier, which means "March beer" in German. The style originated in Bavaria, Germany, where, in 1553, brewing was not allowed between April 23 and September 29 to prevent infection from bacteria in the beer.
The color ranges from golden pale to amber. This medium-body beer is malty and bready, with a sweet beginning and a semi-dry or dry finish. Traditional Märzens are made with Munich malt. Authentic Märzens are lagered for six to eight months at a temperature close to freezing, and today, breweries lager this beer for five to eight weeks. The typical ABV percentage is between 5 to 6% and as high as 7%.
I highly recommend grabbing a few Märzen beers and doing your own comparison to find out what stands out for you. For the three I reviewed, I personally prefer what Empyrean Brewing Company does with Aries.
Cheers!
