Ok then apes, I have some results to report. As a reminder, here’s what I did:
On the 3rd of Feb I mixed up enough flavours and 72mg nic for 50ml each of v5 and custard donut (two bottles, two sets of concs and nic, no vg/pg). I left them to do their thing until Monday the 10th but did change the air in the bottles at least once a day. On the 10th I mixed in the vg and pg and gave them both a vigorous shake to mix the potion up and tried them the next day. Both were delicious but I thought they’d benefit from a few more days to settle down. I can’t exactly pin down why I thought that they needed that, apart from the feeling that the actual custard notes themselves were a bit muted. I tried them again on Friday and have finished the 50mls of donut since then. A properly delicious liquid. I’m no longer thinking about buying a short fill because my mixes are cack. Result.
But I felt like this wasn’t quite clear enough though on whether this technique was really working or not and to what extent it is different to “normal”, all-in steeping.
Slight interlude if you don’t mind; there are two methods/techniques/actions being discussed here - the mix steeping without the pg/vg base and the removal and replacement of air in the bottles. These descriptions are a bit wordy so I’m naming the techniques “pre-steeping” and “venting” respectively. Nobody else has to use these terms but if you read some none sense from me with those words in then that’s what I mean.
Anyway in order to get a better understanding of what does and does not work I’ve mixed up another two bottles of each (100mls each this time as I know I like the mixes). One of each steeping, one of each pre-steeping. Both being vented on a daily basis at least. I mixed them on the 12th. Here’s what they look like now:
I plan to try both on Saturday so a week and a half after first mix. I’ll post back as I get my results if others are interested.
