I had this for the first time from the store. I ordered it as a hot soy tea latte. It was HEAVEN. The balance between root beer tastiness and latte creaminess was perfect. The soy milk added a nice bit of sweet without having to go crazy on the sugar.
I bought some for home but I haven’t had the same success. I’ve brewed it as a regular hot tea, added a bit of cream and sugar. It tastes very weak and bland. I’ve also tried making my own tea latte but I used regular milk and again, bland. I think the trick for a hot latte is to use soy milk. I have yet to try it as a cold drink.
