I have made some Aya a few times, this is what I have found.
If you are using whole vine soak it in a slow cooker on low overnight and turn off in the morning and go to work.
When you get home your vine will be ready to process, the bark comes straight off with a good twist and can be broken up easily. Similarly the core can be pulled apart and cut into smaller lengths. I then put everything through the blender with some of the juice from the slow cooker to really shred it down good for best extraction results. And to those that use prepackaged powdered caapi
The shredded vine was extracted 3 or 4 times with a resulting total of about 16 liters which was always being brewed down. 20ml of vinegar was used in each new refill to keep the pH down. 500g of good vine will do anywhere from 5 to 10 people depending on how much light you add. I liked my Aya good and strong.
I can only comment on acumin-ata phyllodes as the source of light, 150g was too much for the brew, 100 would have been more manageable. 2 tablespoons of cats claw powder was added as well and some other secret processing methods.
When the brew was at about the 3 liter mark it was left to cool to room temperature. 2 egg yolks were added and mixed thoroughly and left for 20 minutes then the brew was brought to the boil, the yolks bind the bitter tannins and clarifies the brew, the resulting coagulated egg is filtered out with a stocking. The brew takes a lovely claret colour, a nice sweetness as well and can now be slowly reduced to 500ml. More filtration through a finer cloth may be necessary if you can still see stuff in the brew.
50 ml cup was too much at the 1.5 hour mark, at the 2 hour mark a second cup was 25 ml which extended the full intensity for another hour, nobody would take a third cup.
On a different occasion 35ml cup then at 1.5 hours 30ml this was too much and left me writhing on the floor 1.5 hours, really intense hard work but very worth while.
I reckon 50 to 100g of 12yr old vine is a reasonable dose of power, the light doesn't need to be added but usually is for obvious reasons.
By my calculations a strong dose (3 cups) will contain somewhere between 100mg and 300mg of tryptamines. If you are not familiar with Aya then half of that might be advisable, say 80g of vine and 50mg DMT (shared between 2 or 3 cups spaced over the night).
I don't believe that measuring crystal and adding that to vine brew is any good, use the plant material and not the freebase. You will need to guestimate your light bearing plant material on further research.
On each occasion it took 4 days to cook properly, and the results were worth the effort.
To ms maniac minxx, are you on the Aya forums by any chance as minxx?
