Good post Jagube. When I have in dreams boiled 25 grams of blended up hawaiian psychotria in 1 and 1/4 bottle of spring water for 1/2 hour, then filter thru a coffee filter made of fine wires, then filtred thru a cotton ball stuffed into a large clean automotive funnel, then reduced down to 3oz, the brew will of course be filtered well and a dark tea colored hot liquid that should be used right away -- as I always found it in dreams to be non-gunk looking and very potent.
p.s With so much good hawaiian psychotria floating around, never saw the need to mess with chaliponga, as my few experiences with it were all over the place,--as it can turn on you in an instance and it's very long lasting so if you get into a challenging experience, it can last a while, I found chacruna to be very forgiving, nice, very potent, streamligned with no physical or emotional weirdness, just pure bliss with chacruna. Chaliponga is definately only for very experienced advanced users like Shamans, etc. I will never go near it again, and if you do ever use want to keep the dose very low like less than 3 to 5 grams max. I ventured beyond that and it was not pleasant at all. The UDV, Santo Daime, Shuar Indian, and all of Benny Shanon's 150+ experiences all only use chacruna as admixture, same here.
Now, if you then take that liquid and stick it in the fridge, a wide stringy & floaty looking gunk falls out to the bottom (and it does seem to diminish the strength of the experience, so I had found to never get rid of it, ie don't decant it out), but if you then re-heat that liquid again, the gunk will redissolve into the liquid to be a clear dark looking liquid once again, but the taste is even worse when re-heated back for some reason, more chalky, no explanation for this, but always prefered it fresh and hot after the 1/2 hour of boiling and quick filtering steps, then a quick reduction of the remaining hot liquid down to 2 to 3oz near shot-like.
I think the alkaloids are still evenly distributed 100% throughout the entire liquid and not just in the gunk if left to fall out in the fridge, as I feel the gunk is simply plant matter that will not come out no matter what the amount of cotton ball filtering, but the filtering does get out any heavy sediment that is irritating to the intestines and causes early purging if not eliminated in my past experiments, so stomach nausea and intestinal nausea can be reduced down to zero with these 2 easy filtering steps, but the bad taste of the brew will never go away, but the taste is still way better if used fresh and hot after the initial filtering & reduction, instead of putting back in a fridge which when reheated say days later then seems to take on an additional "chalky" taste which is extra off-putting to the taste buds in my past experience, anyhow thats my 2 cents.
The taste shock to the taste buds alone just from the leaf portion is off-putting to most people and some will never even give Aya a chance thanks to the terrible taste, but it's not that bad if brewed hot and fresh, still filtered hot, then reduced down to 2 or 3 oz, and dreamed immediately after adding caapi to it. For some reason, just putting it back in a fridge to sit for days after this and then re-heating later makes the taste even worst upon reconstitution of the leaf brew. The brew is already sour and bitter, has a taste like forest rot combined with tangy sourness, and that's just the leaf portion.
If you read experiment 3 from Ott in the pharmahuasca section under thread "chart from the literature", you will see one of his first Aya brews was very bad tasting and they all took a taste of ginger to help kill the taste after it. He then describes the exceptional dream experience. The Shaman had first added alot of weak local leaf, but Ott had already planned for just such an occasion, and asked the Shaman if he could add his own potent leaf to the brew for everyone [and the Shaman said "but of course!"], 50 leaf per person dose, which gave the desired effect he was looking for.
If you can get past the taste, you're in for a treat, as the beauty that Ayahuasca shows you is infinite in it's power, breathtaking is the word.
