Thanks again everyone, the selection has been made and I will be mashing in soon!
When I got to the shop and tasted everything, I found they had another choice, locally-made Skagit Copeland Pils. Staff said it was good and had more of a "hay like" or "grassy" flavor than some others. I had been resistant to that kind of flavor at first ... but since a Kolsch is supposed to be dry and have chardonnay-like notes, that did end up sounding better than a sweeter malt.
So, the final grain bill was 95% Skagit Copeland Pils and 5% Skagit Light Munich. I did want to try Schilling Kolsch malt but my LHBS had stopped carrying it.
I did lot of reading on the style and found more contradictory schools of thought than for most others I have researched.
- 100% pils is all you need!
- Add vienna/munich!
- You'll never taste the vienna/munich, don't bother!
- Add wheat!
- Never add wheat!
- Wheat is not traditional to the style!
- Wheat is traditional if you look back in time far enough!
- Use super soft pilsen-style water!
- Use 50 PPM Ca!
- Use 75 PPM Cl and SO4!
- Use no more than 20 PPM Cl and SO4!
- Use more Cl than SO4!
- Use more SO4 than Cl!
So... I guess there are no wrong answers, and I have a lot of variations to try, hah. Assuming my first batch comes out well I will try upping the percentage of secondary malts on the next run.
For this batch I split the difference on mineral advice, and have about 40 PPM of Ca, Cl, and SO4 in the mash. My tap water is very soft so it is hard for me to have ~50 PPM Ca while keeping those other minerals low, since everything comes from adding gypsum and CaCl2. I'll figure that out on another run.
I'll be using Wyeast 2565 and fermenting it starting at 60F; the yeast advice was pretty consistent.
