Tasting/Recipe : Groundskeeper Marzen

To the beer-uneducated, lagers get a bad rap. The first thing that comes to mind is a pale yellow, fizzy, bland-tasting light beer... ok when you're looking for a lawnmower-beer, but otherwise nothing to usually get excited about. But once you do a little reading, you realize just how many different styles of lagers are available, bready and bitter Dortmunder Exports to malty, rich Bocks.

Out of all the lagers, Oktoberfests (aka Marzens) are my favorite. The best ones are brewed to have a rich, malty aroma and flavor, but finish dry with a moderate hop bitterness. While a lot of authentic German Oktoberfests are a dark golden color, a lot of the ones brewed in North America that you see taken on more of an orange-red/copper hue. Usually not overly high in alcohol (averages in the 5% region), Oktoberfests are easy-drinking beers that I could have several of, and not tire of them at all.

I still have a few bottles left of my first (and only) Oktoberfest that I brewed last May. The recipe is basically directly out of Brewing Classic Styles, and I was very happy with how it turned out. I feel that I hit all the important points of the style, and even after over 6 months bottled, it's still tasting really good. Definitely a beer that I will brew again, and I don't think there's anything in the recipe that I would change a bit.

Appearance: Poured with a moderate-sized, off-white, creamy-looking head that has great lasting power, finally fading to a full-finger. Body is dark amber/reddish-copper, and extremely clear.

Aroma: Strong malt aroma; slight toffee, very bready... the Munich and Vienna malt come through really well. No real hop aroma noticed. No flaws.

Taste: Starts off slightly sweet, but it's definitely not cloying. More bready than anything else. Nicely balanced by a medium bitterness in the finish. Fairly dry. No hop flavor detected. Very clean.

Mouthfeel: Medium-bodied, moderate carbonation. Smooth.

Overall: Very easy-drinking Marzen. Probably one of my favorite beers that I've brewed so far.
