Is there a way to do this in BeerSmith (new or old version) like there is using Denny's instructions with ProMash (see below)? I have my process figured out for the most part, but it'd be really nice to dial it in and leverage the software better.

For Mash Tun Thermal Mass, Enter 0. For Total Grain enter 0.00001 pounds. (It won't let you go any smaller - entering 0 will give you a division error.) This should make your water:grain ratio 120000:1. For Total Water, enter 16.00 quarts. For Desired Strike Temp, enter 170. (You can use any temperature but this will more accurately reflect actual mash temperatures.) For Grain Temp, enter the current room temperature. Heat 16 quarts (4 gallons) of water to 170 degrees and pour it quickly into the mash tun. Close the lid and seal it up, and let it sit for about 5 minutes. Measure the temperature of the water in the mash tun. Enter the temperature of the water in the mash tun in the "Desired Strike Temp" field in ProMash. Now look at the "Initial Strike Water Temp Should Be" window. You will note that, with Thermal Mass set to 0, this number will be the same as the "Desired Strike Temp" field. Now, in small (say 0.1 or smaller) increments, increase the Thermal Mass field until the "Initial Strike Water" field reads 170 (or whatever temperature you started with, if you didn't use 170 for some reason.). Ta-da! Whatever the Thermal Mass field says is your mash tun's thermal mass!

Lots of views, but no comments. Anyone? Bueller?

Dunno, but I'd be interested in this too.
