NO reason to toss them, all will last well over a year
Most commercial juices are really heavy on flavor, 20% or more. Most diy recipes are a lot lower, but you can make them as saturated as you want
As said, it may take some time for the taste buds to recover, but in general, the lower the % flavor, the less gunk. (Some flavors will gunk at low percents.) So coils last longer.
Sweetener... many flavors really don't need additional sweetness, but for those that do I use erithritol, acts like any other sweetener at the same dose, but seems to gunk less.
OK! I'll keep the VG unless it tastes bad. It has been refrigerated but not in the freezer.
I'll look for "erithritol" when I go shopping for flavors around the 20th.
