I promised a review after I tried cold-brewing this, so here it is:
I made up a pitcher of sun-tea with 1/2 decaf black tea, 1/4 Irish breakfast caffeinated tea, and a tea ball of Berry Burst.
It is delicious, and I will definitely be repeating this experiment regularly.
Delicately sweet, it tastes just as good as the hot version, and unlike a lot of fruity teas you don't *need* to add sugar to get the flavor to come out.
