Looking to perform first extraction soon with AANPRB. I've been reading up on it for a while now but I just have a few remaining questions I'm looking to get answered before I give this thing a nudge.

My first question has to do with Earthwalker's tek. I'm looking to add a freeze/thaw cycle to the beginning of the tek and so far I've got the layout like so:
1. Powder 100g bark in coffee grinder.
2. Put in ziplock bag with and cover with 500mL filtered water.
3. Heat mixture lightly in water bath (40-50°C).
4. Return to room temp. and transfer for freeze.
5. When frozen, take out, thaw and refreeze.
6. Repeat steps 4-5 two to four times.
I believe I found a tek incorporating the acidification step during this freeze/thaw cycle but have not been able to find it and was wondering if this would be a possible substitute for the acid bath step.

My second question (or rather questions) has to do with the hot water bathing. What is the best method? What is the best temperature range? If using stove top, what is the ideal way to cycle on/off? In warming NPS, I've heard it is best to do with cap off as to promote evaporation of low-degree NPS, is this true? Will it suffice to put folded cloth at bottom of pot for jar to sit on? Ideally I would like to use a sous vide but if heating via electric stove top is also fine, I'll stick with that.

Thirdly and finally, in reference to this reddit post: https://www.reddit.com/r...inata_extraction_notes/ , it shows evidence to suggest AANPRB doesn't require defatting and I was wondering if that means I could eliminate the mini A/B clean-up stage at the end of Earthwalker's tek as to save on time and resources.

Thanks very much in advance.
