That was directly from the linked paper.
…and you are correct at 150C they were not using SC H2O
Finally getting some qualified people in the lab!

I hear Eugene has more PhDs serving coffee than anywhere else in the whirled.

If you understood bhang, it would open a whole new world for you.
I don’t want to give the alcohol people any ideas…
did you ever see the you tube video…where an elderly woman, Ph.D. chemist…cooks up a kg buds in a pressure cooker with a bottle of olive oil tossed in? Then makes brownies…two guys totally laid out on the
kitchen floor…she says…“I told them not to eat two brownies”.

just gonna leave these here. used the Strada for a few years and it’s a dream. has all the features mentioned above for retrofitting, built in: programmable water temperature, programmable pressure curves controlled by gear pumps.
the Slayer made big waves, on using variables flow rates at the same pressure, instead of pressure curves–at least that’s what they told me at the trade show, website doesn’t seem to agree. anyway best espresso i’ve ever had was from this machine.
and all you need is a cool $20k laying around! willing to bet some of the brilliant minds on this forum could build a comparable system for half the price.
@moronnabis bhangspresso?

No tea for me…
How about basics.
1/4 lb hemp/cannabis in a pressure cooker for three hours…just over do it.
Strain. Look to see where your neutral cannabinoids are. End of conversation?
The tea is good to drink …actually tasty but No cannabinoids to speak of.
All in the mush. Of course there is infinite variation to this …
First step in bhang prep: boil in H2O throw away water. So nothing new here.
Think about it!

I have heard about that special expresso
And flavor variation.

Threw some flower into my espresso. Because why not. Didn’t turn out the way I thought,I’d bet adding straight terpenes would prove better for flavor.

cool! i wonder if terpenes would survive this process, given the temps and atmospheric pressure?
from what I know, they might not, someone in the thread above pointed to the flavors in coffee coming from compounds other than terps, for exactly that reason. I will say though, if you were to use flower from a grapey strain for example, that has esters, thiols etc. that would have a better chance of surviving and being tasted in the brew.
i wonder if putting the flower in the bottom of the portafilter, with the coffee on top, might yield different results?
love the experimentation, i hope i’m proven wrong re: the additions of terpenes. let us know how that goes(/went)!
Just boil some hemp or Marijuana up in water and strain like tea.
Let the tea cool…it is not bad.
But the cannabinoids are mostly insoluble…due to the decarboxylation by boiling.
See @cyclopath below.
I am waiting for a report of someone drinking enough of this tea to get high.

So I tried it with some steam distillated terps
Added one drop to about a quarter glass of water ~3-4 oz of water then poured about a shot worth into my espresso turned out really nice, I was going for the fruity pebbles taste had a herbal note to it. Definitely a lot more flavor experiments to be done.

That is not what the Dutch (I think, I go find) found.
“Tea” was actually deemed a reliable way of dosing IIRC (this should prove interesting…hope I’m not hallucinating again 
)
not hallucinating. same data. not where I read it initially.
also not the same source.
but more rigorous treatment. Evaluation of cannabinoids concentration and stability in standardized preparations of cannabis tea and cannabis oil by ultra-high performance liquid chromatography tandem mass spectrometry
not particularly efficient…(nor as repeatable as the study I recall claimed).

Certainly “some cannabinoids” will partition into hot water”….
I am speaking relatively here. Well I see from the data it is higher than I thought.
My experience is with like 235 F at 15 psi after prolonged 2-3 hr. CBD will always be higher than THC numbers in water. I will have to look at the details of their procedure.
In my case I was comparing what was left in biomass vs what was in the tea after subjecting the biomass to the hot water.
Also if you immediately strain tea at high temp you may well get a different number than letting it sit and cool prior to straining.
In Bhang production there is a reason why they throw the water away.
Now…there is also the other subject of High Pressure Hot Water extraction,
HPHW, something other than what I speak of here.

Bro, I got like 18% yield…
“no cannabinoids” seemed absolute.
18% efficiency +/- 10% is absolutely terrible…
but presumably an espresso maker will up that a smidge.
I’m also pretty sure you can pack 5g into those strainers…

Did you read the HPHW extraction papers…I have posted reference to?
Just put a fair amount of good rec marijuana in a mason jar cover it with water,
Pop it in the pressure cooker for an hour….let it cool to room temp.
Strain and press out H2O tea.
Extract that tea with pentane and dry.
Take the pressed biomass…extract with ETOH…do your thing and tell me where you find the cannabinoids.
So the bioassay for the THC is easy…drink half the tea…let me know if you get high.
Or, As in Bhang, take the waterextracted- biomass and extract with milk/real cream 1/1 by warming…simmer
Like making hot chocolate and add some honey…mix and drink.
There is a lot to learn from Bhang.
But apparently I have learned there is more measurable THCA/THC in half hour hot water boil than I expected.
Can you vary the internal cup pressure on your machine?
One additional difference between the solvent extraction and espresso extraction…
The espresso is vapor phase with flow…hard to say whether it is a steam distillation…With modest pressure.
However…just for the sake of thought….what do you think the state of the carboxyl is for cannabinoids acids that are soluble. What do you think would happen if you added a carbonate buffer to you expresso water….
Best…
