Maybe in the array of flavors, prune out the '0%' entries, if there's text in the flavor name field and the percentage is 0, then move it to notes. This breaks round-trip-ability but makes for a better recipe (IMHO, not having 0% 'empty' flavors and having the 'by: Somebody' or 'Menthol to taste' type of things moved to Notes is a good thing).
You're right about the multiline notes thing. I actually wrote this, then updated eJuice to the most recent version. The one I developed against didn't support notes at all, so it was a bit of an afterthought. I'll fix that.

Line 18: Line separator is '\r\n' (0x0d 0x0a), maybe this doesn't matter in Python?
Line 30: Notes are multi-line
Line 74: 'flavorless' is '0 PG / 0 VG' flag (to turn off the PG+VG=100 constraint)
