Directions:

This beer is more balanced toward malt than a Pilsner, yet light and drinkable and begging for another!

Depending on your setup, aim for an O.G. of 1.047 (11.7°P) and a F.G. of 1.011 (2.7°P). Perform a step mash with rests at 131°F (55°C) for 10 min, 147°F (64°C) for 30 min, 162°F (72°C) for 30 min, then a mashout at 170°F (77°C) for 10 minutes. Avoid too many finishing hops in the boil to preserve the malt-forward attribute for this style. Perform primary fermentation at 50–52°F (10–11°C), perform a diacetyl rest at 64°F (18°C) for 3 days, then cold-crash and package. 

Carbonate to 2.8 volumes and age for 4 weeks. I acidified the mash to pH 5.30 and the end of the boil to pH 5.31 by using my homemade sauergut, which, by my rough calculations, indicated a lactic acid content of 0.68%. (Your mileage may vary.) Judges’ comments indicated a desire for more maltiness in aroma and flavor, so substituting light Munich malt for the Vienna and raising the percentage by 2–3 points may assist one in achieving the glorious nirvana of a perfect Munich Helles!
