The Ice Mountain Data has a very wide range of values for most of the important ones. They have a few wells and I guess the online data lists the variety of different readings they've taken.

One of these days I'm going to do a full decoction, boiling everything and then drain and chill right into the fermentor. In other words, the sparge will be post boil.

Well that day would have been Sept. 5th. I did it. Boiled all 8.5 lbs of grain after mashing and adding more water. To add another wrinkle, I only boiled for 20 min. and used pellet hops that I fried in 6 Tbsp of canola oil, all of which went into the mash tun along with the grains.

I started another thread with all of the details here AG, sauteed hop pale ale - 20 min. boil, no sparge

The post boil sample had no detectable astrigency, and had a nice bitterness to it. I look forward to the final product.

Kai, I pulled samples to do an iodine test but haven't gotten around to it. I took one after diluting, prior to boiling, and one post boil. However even just visually I can see starches were released during the boil. The post boil sample after settling is still cloudy, while the post mash/preboil sample is much clearer.
