I've never had alcohol in my tea before sounds wild o.o
Almost any alcohol would overpower almost any tea, so I don't know if it would taste all that great.
Rum, only a single teaspoon in a cup of Earl Grey, and a cube of brown sugar. It is fairly delicious.
I cant even drink tea with any sugar added, it just overpowers the delicate flavors, even with the smallest amount. Honey is ok in some herbal teas, and milk/cream in some black teas, like Assam, can be good.
