I'm going to try my first Kolsch brew on the 1st, and have been taking guidance from Brad's recipe, and reading up on a few others online. Here is what I was aiming for, but I had a few questions..
I'm using Best Malz Pilsner malt, but am out of Vienna. However, I happen to have some Warminster Floor-Malted Maris Otter on-hand. Anyone think that is a bad idea for a substitute? I know that Vienna and Maris Otter are not the same, but I'm wondering if it's worth a trip to the LHBS on Monday to find some Vienna?Recipe: Condign Kolsh

Sparge: Batch sparge with 2 steps (Drain mash tun , 10.25gal) of 168.0 F water
Also, I've seem some recipes use a late hop addition, but I understand that Kolsch is a malty german ale, with some hop character... but not 'hoppy' in the West Coast sense. I have some extra Mt. Hood, and was thinking of putting maybe 1/2 oz at 30-min of the boil left.. Bad idea?
The water chemistry additions that I have up there are from using the various spreadsheets. This is a very light beer and I know my water pH is like 8.1 .. so I do need to acidify my mash water and especially my sparge water.
Any thoughts & suggestions are appreciated!
