General Info
Start with RO water if possible or target a soft water profile (not Pilsen - that's too soft). Cold steep Carafa for 24 hours in 1 quart of water (use a grain bag). Add liquid to boil. If not using floor malted pilsner malt, use the well-modified decoction regimen (skip the protein rest and start at low saccharification temp of 132 - adjust decoction amount or step mash to target 153 full re).
