I've gotten used to mixing it. In coffee it's not even noticable. I might try the glycerin though just for a test. I've only recently this year began to do tincture and it's quickly become my favorite way to medicate. I need to find a better way, or more accurate way to decarb so that I know I'm maximizing my potency. I'm trying to get a decarb machine but first I'm saving up for a new 5*5 tent. My wife really likes the tincture as well as it allows her to take medicine to work and dose without odor.
I make alcohol tincture (cold/golden dragon method), then I evaporate out all the fluid down to full-spectrum oil and then add a teaspoon of alcohol back into things to make it easier to work with. Then I can use that in a variety of things. Lately my most favorite is to make chocolate with it, mold it into bars then I have measurable 'squares' to eat. That keeps things quick/easy/convenient to use.
I've done sous vide but it's such a pita for just a small amount to decarb.
I like decarbing by sous vide. I use smaller ziplocs which work pretty well, though I think that the timing is a bit more work to nail down correctly. The other method I use is to decarb by oven in a ball jar. Though I do something like 240f for 50-60 minutes (aka, I add a bit of time for the air in the jar to heat up to temp.) Once I did that, it seemed to be more effective and complete.
With decarb by sous vide, you do have to make sure you've really dried your cannabis out for a few days before the decarb though...unlike other methods where the hot air drys as well as decarbs, sous vide traps moisture with the cannabis and you're working against the water with the rest of your process.
