Today, I made it, noticed after a few minutes that the color was pale, but the usual time had passed, so I took the bag out. Just now I took a sip, and looked in the cup.... all the color was at the bottom! And would slosh back and forth without mixing.....
Really, really odd.
A spoon took care of the 'problem'. Now the tea tastes like something besides hot water. Imagine that! ;P
