Session Amber Lager (Accidental Munich Dunkel): Tasting and Recipe



Wow, about 2 months since my last post! That's a record I think. One of the reasons why is that I have decided to wait to post recipes until I do the tasting too. So I have been brewing, but the posts will go up later.

For this beer, I was looking to make a beer that would be reminiscent of an Ayinger lager, especially their Oktoberfest, although once again I did not have their exact lager strain (which would be the Wyeast "Hella Bock" seasonal strain). I wanted it to be dark, melanoidin rich, and slightly sweet, with a big flavor profile but low alcohol. I wasn't looking to make a lager "to style", but I think it's a great example of a Munich Dunkel.


TASTING NOTES:

Appearance: Dark brown with a stable tan head that leaves a great lacing. Ruby highlights, clear but not "filtered" clear.

Aroma: Dark toasted breadcrusts, with a slight fruity sweetness from crystal malts. Very little to no hop aroma, slight alcohol contribution. Robust maltiness and a clean lager profile with maybe just a touch of sulfur (which dissipated as beer spent more time lagering).

Flavor: Toasty, Munich malt derived breadcrust, Moderate sweetness, low caramel flavor, but balanced more towards toasty flavors from malts. Moderate bitterness, very clean. Slight trace of hop flavor, then it ends with dry, toasty malt and clean residual bitterness.

Mouthfeel: Medium bodied, a little chewy, hearty enough for winter or fall but not too thick or filling. Moderate carbonation, low alcohol warmth, dry finish with just a touch of astringency.

Overall: This beer is a hit with Clarissa, who has a high appreciation for drinkable, flavorful session beers (you know, the kind us beer geeks think are "boring" and hardly ever brew). I like it a lot, and it's very close to what I was going for, but still I see room for improvement. I'd like to reduce the "bready" impact just a touch, and increase the perception of a light sweetness by dropping the IBU's just a touch. It's a great "dinner" beer, and you can have an imperial pint and go back for another. This keg definitely won't last long.
