Trashcan Doppelbock

April 13th, 2014

So I bought too much pilsner malt and got a little derailed by moving and house building plans and all that. Time to use all this damn pilsner, spare munich and why the hell did I buy 2 pounds of caramunich when I didn’t need it? Oh and where’d this 2 lbs of vienna come from? What I still have 4 ounces of Hallertauer hanging around? What can I do with all this…..doppelbock should work.

Eh…I still can’t get behind building a mash in beersmith.   I need to be in the 153-155 range so I’m hitting it with 40 quarts at 170F.  Should lose about 4 gallons to absorption so about 15 gallons needed.

Update 4/23/2014

Well I forgot to update post-brew but at least I wrote it down.  OG was about 1.071.  I tried a different sparge so it came out a little low on gravity at 63% efficiency.   I should’ve stuck with the double batch sparge I’ve been using and it would’ve been right on.   Finished well at 1.013 and tastes great.   7.5% ABV so it’ll age nice.

Additionally I considered all the compliments I’ve received recently about young bocks due to hop character so I made a last minute change.   At 5 minutes left in the boil I hit it with an ounce of Hersbrucker.   The hop character is so fine in this malty beer.  I’m excited to get it carbed.
