Hi all - first post on these forums though I've been a casual homebrewer going on 9 years now. I recently switched from propane in the driveway to the Anvil Foundry, and I'm struggling to nail down efficiency and my technique in general with that system. The current issue is, I assume, in regards to the equipment profile for the Foundry that I hope someone can shine some light on. In the Brew Steps under the Mash step it says "Strike water volume is 4.31 gal...", but when I go to the Mash Calculator it only calls for 3.31 gal of strike water. Why the 1 gallon difference? I'm wondering if it's related to the equipment profile for the Foundry, which defaults to 4 quarts for the "Mash-Tun Addition" field. Which one is the correct amount of strike water? Any help with sorting this out would be greatly appreciated.
