Brewed with a spoonful of sugar, per chrimabro ’s suggestion. (Thanks for the sample, Christina!)
I’m not sure what if anything the oolong brings to this. I would be perfect without it since I can’t taste it at all. I absolutely loved this. It was yummy, and rich, and sweet.
I’ll have to rebrew without sugar, or less, to see how it compares.
I agree that the oolong flavor isn’t distinctive at all (it brings caffeine, I suppose? :)), but the spices are delicious.
