Add Hallertauer hops 30 minutes into the boil. Add second charge of Hallertauer with 20 minutes remaining in boil. Add two charges of Tettnanger hops with 10 and five minutes left in boil, respectively.
Shut down heat. Cool your wort as quickly as possible. Aerate wort and pitch yeast starter. Ferment at 48° for ten days. Cool, then rack to secondary for five to six weeks at 40° F. Dry hop with 1.5 oz. Saaz hops. Prime with corn sugar and bottle. Partial mash option:
Partial Mash Option:
Replace Pilsner malt with 5.75 lbs. of malt extract (such as Weyermann or Bierkeller). Steep light Munich, CaraHell and CaraFoam in three gallons of water at 150° F. Omit acid malt.
After 30 minutes, remove
grain bag and rinse grains with one quart of 150° F water. Bring
steeping water to boil, add malt extract. Shorten the boiling time to
60 minutes. Add 11 AAU of Hallertau hops at the start of the boil
instead of 9 AAU of hops for 90 minutes.
