Papua is not the right bean, I think it should be Mexican or madagascar, but take an old 15ml juice bottle, cut a length of vanilla bean to fit, split it into quarters 90% down the length so it stays in one piece, fill the bottle with PG. Let steep as long as possible, shake nightly and will be ready in about 6 weeks when the color gets dark. It's not very strong, but it does the job.

the nut flavor in this juice is way strong day one, but settles into an uncle junk like flavor after steeping. I know it is not a faithful copy because the UJ version tastes like an ashtray when I drip at 0.35ohms on my mech mod, and this version is good with thick clouds. It works equally well at low heat in a tank.
