I'd like to make a Kolsch for a summer brew, and I'd also like to try and move from Extract and Grain steeping to Partial Mash. I did a search on Jamil's Kolsch, and came up with the following:
9.00 lbs Pilsner
1.00 lbs Munich Malt
.5 lbs Wheat malt
.9 oz Tettnanger Pellet at 60
.4 oz Tettnanger Pellet at 5
BrewTek CL-450 Kolsch yeast.
I multiplied the grain bill by .75 to get appr. 6.6 pounds of Pilsner LME. I then entered into BrewTarget, and my OG was a little high. The recipe above was for 6 gallons, and I'll be doing a 5 gallon partial mash - so I scaled the Pilsner LME down to 6 pounds.
My plan is:
6.0 lbs Briess Pilsner Extra Light
1.0 lbs Munich Malt
.5 lbs Wheat malt
Do a partial mash on the Munich Malt and the Wheat Malt for 45 minutes (at 154 degrees?). Sparge. Bring to a boil. Take the pot off the stove and add the LME (yep, I've boiled over on the glass top stove too many times, and scrubbed too much to want to do that again!). Add 1 ounce of Tettnanger pellets at 60 minutes. Add 1 ounce at 20 minutes. Add .5 ounces at 5 minutes.
Using BrewTarget, if I do a partial mash at 5.5 gallons (with a target boil of 6.34 gallons), the numbers come out right. However, I don't have a pot that big, and my stove is not going to boil that much water. If I do a partial mash and partial boil, then add water at the end to bring it to 5 gallons - do I need to increase my hops?
Adding 1 ounce hops at 60 minutes, 20 minutes and 5 minutes bring the IBU to where it should be (but on the low side). But would that make it not to style? Should I use more hops early in the boil, and less later?
Finally, if I wimp out and decide to just go with LME and steep grains - would I substitute in CaraMunich and CaraWheat at the same weights? Or would that be too sweet, and I'd need to look for other alternatives? (I'm strongly considering trying Partial Mash - so the question is probably just academic).
