Look at Mr. Fancy Pants over here with his 9 digit lot numbers and usage of the English language which require me to use Google.
Umm not to be mean or anything but what words or words escaped you grasp of the English language.?
Aliquot most likely. First time I've ever heard it.
A tip for next batch: include some warnings on your labels. If someone other than you has to deal with your stash at some point they should be notified of the danger within.
Also, no need for all that headspace. Like most things, VG's volume will decrease as it becomes colder. The less oxygen the better! Do note, though, that if you use very little headspace there's the possibility of leaking if you let your still-sealed bottle warm up well past the temperature at which it was bottled.
