In that table I read:
Temperature ranges for the gelatinization of various starches:
Sorghum: 69-75C. As far as I understand these are usually optimal temps. Thickness and pH of mash also play an important role. I think you simply mash within that range, I don't see why that's not possible.
Potato: 56-71C.
So there is an overlap there!!!
Further it says:
Green zone in the table= common saccharification test range, whatever that is. I suppose that's the standardized testing protocol range.
And:
Starches marked with (*) also benefit from boiling before being used in the mash.
It says "benefit", so that doesn't mean they have to be boiled.
In my bible the test temp for Dari (sorghum) was 30C !!!! That's very low.
Test temps for regular barley malts were 30-60C.
I have no numbers, but from my experience I would say that enzymatic activity probably starts from just above freezing (as in sprouting grains and seeds, that what the enzymes were meant for). The activity will be less and increase with temperature. There are of course optimal temps for the fastest conversion of starch into sugar.
As an example: watch what happens when you make like a pancake batter and leave it at room temp:
liquification > saccharification > alcoholic (yeasts) and bacterial fermentation (lactic acid bacteria etc.) You'll end up in the end with sour dough, but at some point you get a brown liquid on top that tastes very sweet: you've been brewing at a low temp.
I think you guys should just simply try and not be fooled to much by theory.
You'll find out with a simply iodine test if it works or not.
You may not be able to make clones of commercial beers,but who cares, become a beer inventor!!!
Do some very small sample tests...
