Haha, it's our humongous San Pedro, lurking curiously at its colleague... He has a bunch of little kids in separate pots spread throughout the house as well!I'm kinda more interested by the cactussy-looking action looming in the background
The precipitate at the bottom looks pale and kind of sparkly... Make sure you don't throw anything away just yet!
Sabnock, how many freeze/thaws do you usually do? Pics below are the brew after the first thaw and after the last one (fifth); after thaw 3 only very small amounts of plant matter dropped out. The brew does remain darker at the bottom than it does at the top, though.If anyone is down for a little experiment, trying making a simple brew from Mimosa or Acacia, and then completely freeze and thaw the brew a few times or so, which will precipitate/crash out all the tannins and plant gunk and oils and such from the brew and cause them to collect at the bottom of the container. The issue with this is that when filtering the liquid, sure a lot of plant gunk can be filtered out pretty easily but tannins can still merge back into the water while it's going through the filter, unless you suck up the clean tea portion with like a syringe and don't disturb the sediment at the bottom. I do this with my teas as to make them palatable, and it can be very effective in producing an easily drinkable Mimosa or Acacia tea, but it's also crossed my mind to try it for extraction as well, although my DMT extraction game isn't nearly as good as other people's and so i'm still getting the hang of it and for the most part i just go with oral DMT-containing plant teas or a full spectrum 99% iso alcohol freebased oil evaporated onto herbs for Changa/enhanced-leaf and haven't really dove into extraction in awhile to test it out, my line of thinking is that it should make a cleaner extraction and with reduced risk of emulsion and nothing in the way of like plant fats or what not as ime the more freezing/thawing you do the more all of the gunk including the fats/oils crash out and fall to the bottom of the container which then the clean portion of tea can be filtered/decanted/siphoned away from the sediment at the bottom.


The tannin removal of MHRB vodka extract proceeds exactly like in the Robert Murray Smith video. The ABV in the range of vodka was found by Chinese researchers to be optimal for tannin precipitation (which is rather fortunate, really!) A brief test, performed by washing the filtered-off tannins with 70% ABV grain spirit revealed that the higher percentage alcohol causes coloured material to redissolve from the precipitate.Also @Transform : In another thread a post of yours seemed to suggest that you de-tanninized your vodka tincture (mentioned earlier in this thread) and consumed it. (Can't find the post.) Or did I misinterpret? If not, can you tell us about the results?
AE = Alcohol extraction. (// common acronym CWE = cold water extraction).AE = Alcohol Extracted? Alcool éthylique? Or something else?
Is there somehow a difference in, say, doing one 'soak' with 300ml of alcohol versus three 'soaks' with 100ml of alcohol?I would still recommend doing three solvent runs on a given portion of of bark, using fresh solvent each time.
You will pull more using 3x100mL than with 1x300mL. Even if more dissolves into the 300mL than can fit into 100mL (which, incidentally, with ethanol doesn't make that much of a difference because of the very high solubility of DMT in that solvent), assuming the volume of solvent is sufficient still to be separated easily from the plant material, the succession of three smaller washes will result in more of the target product being recovered overall.Is there somehow a difference in, say, doing one 'soak' with 300ml of alcohol versus three 'soaks' with 100ml of alcohol?
EDIT: With 'soak' here meaning the MHRB sits in grain alcohol at room temp for a month or so and is swirled around regularly.


Thanks again @Transform
@Sabnock1990: With how much water do you freeze/thaw in the case of a 100g MHRB brew? Is there an ideal amount in the case of water?
At the moment I have a 60g MHRB (96% alcohol) tincture evaporating. I plan to redissolve it in 0,5l of water and was thinking of adding some citric acid to it- but I am clueless as to what an appropriate amount of citric acid would be?one option would be to acidify the tincture before freezing.
If you're planning to evaporate after freezing, it's better to use a volatile acid like vinegar or HCl.At the moment I have a 60g MHRB (96% alcohol) tincture evaporating.

Note also that I intend to evaporate the water at the end of the freeze/thaw process, not sure if this matters or not.

Some further questions:urified DMT. This may have been due to the participant falling asleep and then waking up again once the effects had commenced. As a word of caution, the waking into the jurema visions seemed to have a pre-convulsive edge to it. In that respect it may be wise if this method was reserved for those who have some considerable experience of meditation and consc
Whoops, lost track of this one! Some of the details are a bit vague, maybe in order to encourage experimentation and use of calculation methodsSome further questions:
Hopefully @Denverevolution will be reporting back as well.
- How 'pure' was the lime treated tincture as compared to the not de-tanninized vodka tincture? How was the experience in terms of nausea/body load?
- How much lime did you end up using? Your earlier speculations in this thread would suggest 30g lime for a 60g MHRB tincture, did this prove to be accurate?
- EDIT: And how about potency? How much of the tincture did you consume (with how much rue tea?) and do you think DMT was lost during the precipitation?
Definitely not because of being disorganised and endlessly distracted, no sir.So, 6ml/300ml tincture ~ 60g MHRB would be 1,2g MHRB worth of tincture?6mL of the tincture was sufficient to produce a noticeable effect of brief duration (although it will have started while the subject was asleep, and thus some of the chronology will have been "lost"); the amount of rue seed used was around 2g but with an ongoing background level from daily rue microdosing.
If this were your only option I would advise using white rum rather than a darker-coloured variety if anything, but rum has a distinctive flavour and some of those aroma compounds may react with components of MHRB, whereas vodka is, by definition, neutral grain spirit, i.e. it has minimal levels of these 'congeners', so it's your call but I'd still recommend using vodka.So, 6ml/300ml tincture ~ 60g MHRB would be 1,2g MHRB worth of tincture?
Sounds promising, then!-- Although the post-lime tincture was probably a bit less than 300ml?
I have some lime coming in the mail, will probably be trying this approach in August somewhere.
EDIT:
Just 2 more questions:
-I assume rum would work just as well? Reason I ask is that I have some rum in my cabinet that will never otherwise consume. (It's 37,5%).
-300ml vodka for 60g MHRB strikes me as a low amount of volume? How did you arrive at this amount?
