I'm curious - when you say you couldn't stand the smell or taste, was that FHO?
Yes it was greatwolf. I made that batch in the IP, blending with oil and water then separating the oil and water after straining. It infuses and decarbs fine, but the taste was awful.

Hi Sue, this makes a lot of sense. And I think it will to you too in just a few minutes. If you'll recall, this has bothered me for a while, but I couldn't explain it. Now I figured it out and can explain it by cooking techniques.

When you typically prepare FHO on the stove top, you are basically sauteeing the leaves in EVOO until all of the water has been driven out and the decarb process has been done to your satisfaction. Yes, I know it is a lower temperature then sautee is done at, but the basic principle is the same.

This does not even come close to what is taking place in the Instant Pot (IP). When you add the additional water and close the lid, we can't see what happens but we can make some educated guesses. We know the oil and water won't mix, they will separate. We know the plant material, being made up of mostly water, will enter the water layer. When the water starts to boil, this agitation will further remove oil from the plant material.

[Don't believe me? Chop up a couple of fan leaves, mix with oil, put in a pot of boiling water and see what happens. ]

So in the IP method you are using, you are boiling the material vs the sautee-like method you use on the stove top. This is why you and I got drastically different results: I'm using dry material mixed with oil, separated from the water used to pressurized the IP (mine are in canning jars with the lids loosely on).

What might work is the following:

Place cannabis oil mix in a metal bowl.
Place a heat safe jar/ glass/ can in the middle of the bowl.
Forming foil in the shape of a shallow cone (pointing into the jar), tightly cover the bowl.

Since we're trying to remove water in an extremely humid environment (pressure cooker), we need to set up a water condensing/ collection system, which is what I've tried to describe above. I've no idea of it would work. But I'm sure it would smell and taste better than boiled cannabis buds.

Cheers from the dark side

I can vouch for that. Everyone had to leave the house when I did this to kill botrytis. Boiling water on the bottom and buds above in a steamer pot (lid off in this pic, it was boiled with the lid on):



The smell was was disgusting! Can't even imagine the taste :0

[QUOTE=SweetSue;3880947]I went back to the stove-top method. I couldn't stand the smell or taste of the previous batch done in a pressure cooker. Today I harvested a CBD Critical Cure mand tossed her into the stock pot sitting in the oil bath and went old school. :slide:

200 grams of buds and sugar leaves in 250 ml of EVOO, reduced to an indistinguishable mash?


Hi Sue, a couple of questions for you and a recommendation.

1. Your "formula" for FHO - 200 g bud to 250 ml I get. Dried bud would be ¼ or 50g, correct? Does the amount of oil remain the same?

2. What is the current thinking/practice regarding a two-hour vs eight-hour vs a 36-hour oil? There seems to be movement to less time in a low heat oven. Obviously, decarbing the material needs to be done prior to cooking. But, if decarb is a matter of time and temp: higher temp, shorter time; lower temp, longer time, how long at 140° F would it take to Decarb? Or would it at all?

I only able to press 150 ml of oil from the mash. That 100 ml of infused oil locked in the plant material will be loaded into capsules and dosed like that. It'll extend the harvest and we might squeek through to the next one.


Finally, not sure I've seen this posted, but here is what I use to squeeze out every last drop (well, almost every drop) of oil. I put the mash in silkscreen (or cheesecloth) wrapped in a ball. This is a very heavy duty juicer - cast aluminum, and though at 70 I don't have the strength I once had, I can really crank on this and get most of the oil back. Unfortunately, this was gifted to us and I'm not sure where it came from. A specialty shop, I believe. Couldn't find this one on "the river", but they do have a stainless one for $20+.

Sorry to take so long to get back to you

I have a squeezer very similar to that. I like yours better. Lol! I use silkscreen silk for straining my oils, I believe it's 125 TPI. On a good day I can recover most all the oil, and I fill capsules with the mash and take them too, so no waste.

When I use dried buds the oil measurements stay the same, and I figure dried buds at 1/4 the weight of wet. Your calculation was spot on.

We don't decarb in advance when making FHO. Decarb is the last step with this method, as it is in the making of CCO. I use the pressure cooker to make my oils with dried bud, so all I need do is break the buds down fine enough that I'm certain I'll get a good extraction, cover in oil, cover the pot-in-pot with foil to keep moisture out of the brewing oil, and go.

I did some hot oil bath testing on the 36-hour oil and we discovered it wasn't decarbing anywhere near complete, even after 36-hours at 170 degrees F. That was about the time I invested in the pressure cooker, and it has made my life so easy I can't believe it.

Using buds dried low and slo I'm getting an oil very close to FHO made at the point of harvest. Made that IP worth every penny to be able to set it up and walk away.
