I found a bottle of vanilla custard I mixed at least a year and a half ago. Two yrs even . It is not discolored at all. I'm not a fan of custards, was making this for a friend who eventually gave up vaping and went back to...gag....wintergreen snuff. I tasted of this on my finger and was completely blown away. I've heard custards need time to develop. This stuff is near amazing. I'm cleaning up an rda shortly just to give this stuff a whirl. It may well change my mind toward custard because it smells and tastes so freaking amazing. It's at least a year and half in the bottle steeping away forgotten and unnoticed till today. Any thoughts or ideas on this?
