Well honestly I'm in a bit of a conundrum there Don.
My fermentations have suffered from terrible attenuation like averaging only 50% + really bad.
All year I've been working on this issue trying to erk more out of the fermentation.
Mashing really long 6hours overnight rising step mash falling step mash adding more Amylase enzymes adding inverted sugars warming up the fermenter adding yeast nutrient pitching on whole yeast cakes all result in similar attenuation limits around 50 -60 %.
Now is it the yeast I thought serially repitching well I used it in a batch of cider and it attenuated down to .004 so not that.
Long story short I've come to the conclusion is it's a conversion issue or unconverted starch issue.
Amyloglucosidase is designed to create glucose a highly fermentable wort used for distilling or high alcohol beers.
I'm thinking of using this in the mash therefore being able to hopefully over time fine a sorta measurement 60 minutes of mash time = X amount of fermentable wort.
Adding it to the fermenter I'm thinking it won't stop until it's broken down all the carbohydrate molecules into Glucose units resulting in a yes heaps attenuated dry beer but with no flavour.
Sorta like a diastaticus nightmare and I'm introducing it on purpose yeah no Thanks lol!
Straight up rice has a high geletanisation temperature 85c so it's hard to break down them starches to begin with.
My last brew day I mashed in at boiling and let it drop to 85c where I added my high temp alpha Amylase enzyme thinking beauty I've geletanised the grains and made way to Amylase to start cleaving at the 1,4 1,6 linkages.
I'm getting great conversion on that batch I hit 1.065 og on a 1.056 ish beer Ozarks Q4 Amber but maybe some of them starches are still un broken.
That's sitting at 1.033 ATM so once again 50% attenuation on the sugars produced from that mash.
The new Deltamalt Enzyme might help as well Who knows it's a different blend than the Ondea Pro I've just been using since start of year.
One last thing I do want to try is a double decoction mash maybe by decocting like the old school brewers did with poorly modified grains might help.
I'm expecting my home maltings arnt nowhere near that good.
Anyhow there's an insight into my Gluten Free brewing Conundrum.
I'm fairly confident this AMG Enzyme will sort it out
