Sorry, Chris, misread part of your post yesterday. Got to try out a new and exciting combination of meds last night, wheeee ....
Anyway, there is a massive difference between steeping for weeks, and just vigorously shaking, letting it sit for some hours.
While Diacetone has become so unfashionable, good creamy or custardy flavours are getting tricky to find, that is just one of many different "evil chemicals!!" that won't diffuse through your juice in any hurry.
Back when I'd still buy the aromas sold specifically for vaping, and paying the surcharge on there, I'd notice some aromas would come with a steeping recommendation of a few days, with a 50/50 base. Others would be sold "no less than two weeks!!".
I've tried just letting steep either variety for a day or so. Just shake until the layers of stuff with different density had dissolved, one homogenous looking mess, let sit. The flavour could be anything between "Wow! This is what actual nothing tastes like! I now have a new zest for life, I must live every second to the max! Taxi! Vegas!!" and "Wow! This is what my favourite, delicious juice tastes like after it has been weaponized in a Soviet-era chemical weapons lab in Kazakhstan, was used by a central-asian despot to decimate a troublesome province, there polluted the narcotics crop, thus ended up being swallowed by some douchebag-techno-boy and finally being pissed out, into a Soviet era urinal in the greater Petropavlovsk metro area."
Seriously, I'd get hit in the head with something that only faintly resembled one of my favourite flavours at the time, but that made me honestly retch. It was a dirty urinal, too.
I've been using my magnetic stirrer for so long, I couldn't even remember rules-of-thumb for how long to let stuff steep.
I googled, and this sounds about right:
- tobacco and chocolate aromas take longest to steep sans heat, 14 days or more.
- vanilla, nutty things, creamy stuff, 24 to 72 hours.
- most fruity aromas, if used with a base suitable for easy diffusion, can be vaped immediately.
However, like for any rule, there's an exception. Especially for rules of thumb around here.
My favourite Tiramisu aroma, that I ended up with after trying quite a few from different brands. 14 days is the recommended minimum steep time for that. Mad coincidence of chocolatey, creamy and fruity. I did try with just a week once. Not so good. About 12 to 18 hours on the magnetic stirrer, fine as can be.
Stirrer recommendation: pay attention to the magnet. Ideally, you want the poles on opposite sides of the axis, radially speaking. Nice, strong neodymium. I just glued a magnet out of an old harddisk in the middle. It works, and I don't fix what ain't broke. But it could work better.
Trouble: tiny little magnets, they don't do the job very well. Big old magnets don't spin up very quick and don't reach a high maximum speed. You want your magnet to spin as quick as possible, obviously. However, at some point, the fish won't be able to accelerate along with the rotor. At that maximum speed, the fish will "decouple" if you will, and then sit in the dish, just faintly vibrating, while the rotor can now spin up to full power.
You need a little finesse to set that up. After starting up the thing, set at one speed or another, don't alter the speed setting immediately. Wait. It takes a minute, literally a minute, for the fish to accelerate in high-VG, comparatively high-viscosity juice.
You want to find a speed where there is vertical movement of juice. Ideally, the-force-that-shall-not-be-named will create a funnel above the spinning fish, and you can see it all rolling around an annular, horizontally oriented axis, while also spinning around the vertical.
After initially reaching that, the funnel max actually close up a little as more liquid accelerates, but that's okay.
If there were absolutely anything to be afraid of, don't you think I would have worn pants?
I said I have a big stick.
