I have never tried real buttered rum, but this tea is buttery for sure! You know, just the same buttery aroma when you buy popcorn at the cinema. :) I can’t really taste anything like rum in the tea, but this is a sweet-smelling tea and I think rum is on the sweet side too? The tea actually can appear a bit oily because savoury butter and fatty coconut dominate the cup! (And you can clearly see oil droplets floating in the cup :P) But you’ve got to admit that it tastes pretty nice and is a warming winter drink!
