Giving this another shot (although, I haven’t logged it before for some reason…bad Steepsterite!). It’s simply not tart, it’s just bitter. And for a flavored black, especially one named for a fruit, one has greater aspirations. I’ll drink this pot and update if the liquid nearer to the leaves brings some tartness (didn’t mix well post-infuse…which reminds me… new teapot! 34 ounce version of this: http://www.amazon.com/Bodum-17-Ounce-Glass-Stainless-Steel-Filter/dp/B000MWG4CY …love the spout).
