I'm just starting out and am still sampling things here and there. So far my favorites are butter rum, banana nut bread, and USA mix. I'd really like to get my hands on a good vanilla. So far they've all tasted like a bland vanilla extract which smells great, but I don't want to vape it.
Flavors that I don't care for so far are citrus and cinnamon varieties. Although I have enjoyed adding a few drops of horchata flavored e juice to my banana nut bread.
