All Grain Recipe: #15 Munich Madness Oktoberfest Ale

I recently brewed up a Mr. Beer Oktoberfest Vienna Lager kit, batch #9. Like all Mr. Beer kits, this isn't a true to style beer, but rather a hybrid of Oktoberfest and Vienna Lager brewed with an ale yeast. I brewed it with a Nottingham ale yeast, a quarter lb. of Crystal 15, 1.5 lbs. of DME and 6 oz. of Booster. It turned out really great, even though it has only had two weeks to carb/condition, and has me itching to do a non-kit version of the same style.

The biggest difference between Vienna Lager and Oktoberfest is that an Oktoberfest generally has a Crystal malt presence and more hope character. Another obvious difference is that commercial examples of Vienna Lager are very difficult to find. Negra Modelo is a good example that I enjoy, and Trader Joe's sells a decent one that is brewed by Gordon Biersche. 

In contrast, Oktoberfest is a German lager and is brewed by several German breweries, including Spaten, Paulaner and Ayinger. Oktoberfest lagers were brewed in March ('Marzen') for consumption during festivals in the fall ('Oktoberfest'). 

Whichever way you go, you'll get a clean, malty, dry beer with a focus on malt and a roasted flavor. It goes down easy with a dry finish that makes you want to drink more. I find this style to be the most refreshing of the 'darker' beers one can find.

My main problem is that brewing lagers is a pain in the ass - one that I don't find to be worth it. Why invest in a brewing refrigerator and spend 2-3 months lagering your beer when you can get something that tastes just as good or better by using an ale yeast? True, it might not be true to style, so you may not want to enter it into a competition, but the end product will be just as drinkable.

Below is the Oktoberfest recipe I plan to use from Brewing Classic Styles. The original recipe is for 6 gallons at 70% efficiency, but I've scaled it to 3 gallons at 85% efficiency. The hops are tweaked slightly based on advice in Designing Great Beers, which says to use 0.75 oz of flavor hops and target an IBU to Gravity ratio of around 0.5. I'm also trying to get rid of around 40 grams of Hallertau I have in the freezer.

Finally, I substituted the WLP029 Kolsch ale yeast instead of using the WLP820 Marzen yeast. The WLP029 is supposed to give a clean, lager-like flavor that works well in this style. It supposedly creates a bit of sulfur early on, which goes away with aging. I'll be fermenting lower than normal, around 65 if I can, but I'd like to avoid getting too much diacetyl in the end product.

Below is the BeerSmith brewsheet for the recipe scaled to my equipment and efficiency, followed by the original 6 gallon recipe.
