Munich Dunkel

I still remember my first experiences with lager.  The very first was a sip of my dad's Old Milwaukee when I was eight; I can't say it agreed with me.  In college in Boston, Sam Adams frequently showed up at parties, and while it was one of my first welcome introductions to craft beer, I can't say I was really taken with it.  And at the tender age of twenty one, I was offered my first Bud by the drummer of a band for whom I was working merch; the fact that it had about the same taste as a glass of water did not make a great impression.  Following experiences like this, my initial homebrewing instinct was to stick to ales; they were by far what I preferred to drink.  While I've had a few decent craft lagers over the years, I was never swayed to try making one myself.

That was, until I spent a week in Santiago, Chile last October.  Chilean beer is currently experiencing a craft renaissance, but the traditional beers of the country (and many other South American countries) are German lagers.  I had a number of really exceptional lagers while there, but the one that really nailed it for me is the one pictured here: deeply malty and supremely drinkable.  It wasn't too hard a sell sitting in an outdoor cafe in downtown Santiago, enjoying the Southern Hemisphere's early spring weather.  Unfortunately, I can't remember the brewery that produced it, so I couldn't look into it further.  But it was the beer that finally inspired me to really give lager a shot at home.

Lacking a lot of lager knowledge, I couldn't decide if the beer from my memories of Chile was a Vienna lager or a Munich dunkel.  Digging on darker beers for the winter months, I decided to follow the road to München.  (Looks like the inspiration is more a Vienna, though; that may be the next up, then.)  Nearly entirely Munich malt, with just a pinch of dehusked Carafa for deeper colour.  A very light brush of neutral bittering hops, with Hallertauer to finish.  Not knowing my lager yeasts, Wyeast's Munich Lager strain seemed like an easy go-to for the style; building a proper starter took some time, but was well worth it to have a good pitch of yeast.

Brewday went smoothly, leaving my only other big worry being my ability to actually lager, which I did in my swamp cooler with water along with a bunch of ice and ice packs.  I was shocked when I realized I'd made it a full month keeping the beer at a fairly constant low- to mid-30s F with this method.  While it's not perfect--I could stand even more malt character--this could be the start of a long, positive relationship of lager in my homebrewery.
