I don't know what it is about FA's espresso, but mixed in small quantities, without much else added (maybe a hint of vanilla and some cream fresh). It tastes just like honey smacks to me. Albeit not as sweet as the cereal, but the taste is totally there. I added a Caramel Macchiato recipe awhile back, a decent variety of flavorings to make, but after a 5-7 day steep time, vapes just like a warm, caramel-y sweet coffee drink.
