This flavor is made with organic Oolong tea and then we add mulling spices to it. It tastes delicious chilled but when it is cold out I like to warm it up. It releases the essential oils of cinnamon, all spice, and orange and warms you from the inside out. This is a great alternative when it gets cold out. Be aware that you don’t heat it over 115 degrees to preserve as many beneficial organisms as possible.
