Dunkel Weizen

My first Dunkel Weizen. I was looking to do a German beer in conjunction with the trip. I don’t have the fridge for lagering, so an ale yeast was needed. Irish Mike suggested the Dunkel.

Grain Bill

  • 5 pounds wheat malt, white, American 2.5 L
  • 4 pounds Pilsner malt, Briess, American 1.2 L
  • 8 ounces Special B malt, Belgian 150 L
  • 4 ounces Carafa II- chocolate malt 400 L

Hop Bill

  • 1 ounce Hallertau leaf (5.1%) 60 minutes


  • Wyeast 3068 Weihenstephan Weizen
  • 1 pill Irish moss
  • 1/2 teaspoon phosphorus acid to sparge

Mash Schedule

  • Strike 3.5 gallons at 108 F. Mash temp was 105 F (and a little too thin).
  • Raise temp to 122 F. Hold 30 minutes.
  • Remove thickest 40% of mash to second kettle. Raise to 158 F & hold 15 minutes.
  • Boil second kettle for 30 minutes.
  • Recombine with rest mash. Target temp is 147 F (came in at 141). Added heat and rested for 15 minutes at 147 F.
  • Raise to 158 F and hold 1 hour.
  • Mash out at 170 F for 10 minutes.

I was very disappointed that the first two bottles of this beer were flat. WTF? Both were old swing top bottles, so maybe the seals went bad (though they were fresh gaskets). I’ll try a capped bottle next. They shouldn’t need to sit any longer. There should be some carbonation a month after bottling. We’ll see.

Results- November 2011

Well, this one didn’t make. This is the first beer in quite a while that was such a disappointment. I have sampled the beer over the last couple of months, hoping for an improvement on the carbonation but have seen little in terms of improvement.

The beer is still flat. There is a slight head on first pour but it disapates quickly like from a can of Coke, not like a weizen. I think the beer itself isn’t bad, but with few bubbles, the profile is all wrong. I’ll end up drinking this slowly this winter but won’t share it as it is a poor example of my brewing practice.
