Can you expand why you want this particular version of ayahuasca and not others?  Why only p. viridis (if chaliponga is also used "traditionally"? What is wrong with a fridge (not that Ive ever seen it used in an ayahuasca brew anyways, except when storing... ) ?  Not trying to challenge you or anything but I think often people have an idealized version of shamans and indigenous cultures, and think there is some sort of consensus amongst them regarding ayahuasca rituals and preparations, and this is not true, some are very different from others so you would just have to arbitrarily chose one tradition over the other. This is of course fine to chose, just know that its not The way but just one way from one particular group (or groups) that you somehow decided to follow

That being said, I think a 3x3 hour aya brew with B. caapi and Psychotria viridis can be amazing and it's very cleansing/learning/beautiful/terrifying/amazing to take such brews

Also Im still wondering if yuo have checked the FAQ and specially if you had experience with other psychedelics.

Be well!
