Target Water Profile

Munich (decarbonated)

Ca⁺²	Mg⁺²	Na⁺	Cl^-	SO₄^-2	HCO₃^-
52.4	9.3	23.4	75.2	51	1.2
Need 18 gallons. Use 12 gallons RO water and fill to 18 gallons with Serrano water (6 gallons added). Add 5g (1.0 tsp) CaCl2 and 2 ml lactic acid. This gets close to Munich decarbonated profile, but a little low on sulfates. Results in very malty beer.

Notes

This is a high gravity doppelbock, with very low hopping rate appropriate for style. Made only with German Munich, German Pilsner, CaraMunich III 60L and Cara Aroma [for dark fruit flavors]). Melanoidin malt added to account for not doing decoction.

Need huge starter for this. Using yeast cake in Torpedo keg used to ferment Märzen/Oktoberfest with Saflager S-23.

Mash: 20 min at 128F (protein rest), 60 min at 150F (beta rest), 30 min at 158 (alpha rest), 10 min at 168F (mash out).

Boil: 60 min, with Hallertau Mittelfruh added at 30 and Hallertau Hersbrucker added at 60 minutes.

This beer is named Dilator since heavy alcohol is known to dilate the pupils, etc.
