I am planning on doing my first partial mash soon, Kolsch. I want to try to do a late boil malt addition. I will mash then boil 45 min then add DME. I have put the recipe below and broke the IBU additions up into the first 45 min (with only mash malt) and the last 15 min (with DME added). I think I did it right. Comments are greatly appreciated.
Grains:
2 lbs. Bohemian Pilsner Malt (Moravian) 1.8L
1 lb. munich malt (4-7 L)
8 oz. Flaked Wheat 2.0 L
Mash 90 min at 152F
Add water to 3 gallons.
At this point, with 60% efficiency, the SG should be 1.025.
With a SG of 1.025:
Hops:
0.5 oz. Hallertauer (at SG 1.025 for 45 min 7.7 IBU; at 1.085 for 15 min. 2.4 IBU)
0.75 oz. Saaz (at SG 1.025 for 45 minutes 10.1 IBU; at SG 1.085 for 15 min. 3.4 IBU )
With 15 minutes remaining:
4 lbs. Extra light dried malt extract (1-3 L)
SG now at 1.085
Boil for 15 min more.
Flame off:
1 oz. Saaz (aroma)
Dilute to 5.5 gallons.
OG 1.046
Adding it all up, 23.6 IBU
Yeast:
White Labs Kolsch
Expected FG 1.012 (75% attenuation)
The IBUs are a bit high for a Kolsch, but if it evaporates some this should bring this down (not too much I hope; BU/GU=0.51)
Thanks!! I don't want my Kolsch to come out as dark as molasses like my hefeweizen did.
