If you're looking for the pale yellow festbier, this should get you into the right neighborhood, for 5 gallons or 19 litres:
7 lb German Pilsner malt
3 lb German Munich malt
1 oz Hallertau Tradition (45 minutes)
Wyeast 2206 (accept no substitutes)
Make a big 3-quart yeast starter a few days in advance.
Single infusion mash in 100% distilled water about 149 °F for 120 minutes or overnight. Pitch and ferment at 50 F for 6 to 8 days, then raise up to 65 F for several days or until diacetyl is gone. Then lager if desired, bottle or keg as normal. Might improve after 4-5 months lagering in the bottle/keg.
