Kölsch-Style Ale

Brewer :   Alan McKay  
Objective :   Not doing much special here, although we are going to compare 2 yeasts. Munton's Gold, and the BOP Lager that I use.  
Method :   All Grain  
Date :   98.05.23  

This is another slight variation on our standard recipe. We've added an extra 2 lbs of 2-Row, and used 50/50 Vienna/Munich instead of the regular straight Munich. 153F rest, and all the rest is pretty standard stuff.

Ingredients for 40 litres :

  • 14 lb Canada Malting 2row
  • 1 lb Hugh Baird Munich
  • 1 lb Hugh Baird Vienna
  • 1 kg Canada Malting Wheat Malt

Mash Water - choice between the following three ratios to hit 153F. Chose the first one since there was no risk of maxing-out the tun with only 18 lbs of grain, and wanted to be as close to a ratio of 1.25 as possible.

Volume Temp Ratio
22 qts 166.5F 1.222
21 qts 167.2F 1.166
20 qts 167.9F 1.111

Procedure :

  • 10:05 Mash in 22 quarts of 166.6F water to reach 154F
    adjust with frozen (and sanitized) 2 litre pop bottle to 153F
  • 10:15 begin rest 153F
  • 11:25 check for conversion. OK. Recirculate, have trouble with bottom floating, but eventually got it to run clear just fine, without grain coming out. Add 8 litre boiling water to bring to mashout temp of 164F.
  • 11:35 begin runoff
  • 11:55 transfer 27l to kettle, turn on heat
  • 12:15 transfer 27l to kettle, run off 4 litre more and add to kettle
    final runnings SG 0.995 @ 130F (60F:1.008)
    OG (58l) 1.021 @ 149F (20C:1.038)(38l:1.057)
    90% efficiency
  • 12:35 tank #2 runs out, change tanks
  • 12:55 boil commences
  • 13:10 add 2.0oz Winemaster Hallertauer (unknown alpha)
  • 13:55 add 3/4 oz same, 1 tbsp Irish Moss
  • 14:10 immerse gooseneck
  • 14:20 turn off gas, whirlpool
  • 14:30 start chill
    OG 1.039 @ 74F (60F:1.040)

Lower OG than expected, but didn't get as much evaporation as usual, presumedly because it's getting warmer out. Ended up post-chill with 44 litres instead of 40, so the adjusted gravity would have been 1.044, right where I had wanted. Next time must compensate for the lower summer-time evaporation (either run-off slightly less, or boil a bit longer before adding hops).
