I think this is one you have to be very careful with when measuring out the leaf. You have to make sure you get enough caramel pieces and I think it does better with a little bit more leaf than less. The first time I had it I underleafed it and it tasted of slightly sweet watery rooibos. This time I used 2tsp for about 11oz of water. It came out smelling like nutty skillet toffee. The rooibos is still there contributing a little dryness and a nutty woody note, but the flavour is of vanilla cream caramels. Pretty nice tonight.
