Day 19 of the Plum Deluxe herbal tea advent calendar. I tried this hot. I tried it brewed long and strong, and per instructions. I tried several cups of it. All were extremely unpleasant, I assume because of the horsetail. I’ve never tried it before and don’t particularly care to again! I finally found a way to at least make it drinkable – brew according to steeping instructions and then let cool until it’s iced tea. That seems to mellow the horrible horsetail flavor. The lavender in this is pleasant enough, I just can’t quite get past the other, hard-to-describe flavor. It’s not quite bitterness or tartness… I can’t describe it, it’s more like a sensation than a flavor really. I don’t know that everyone would have the same reaction. This might be some personal quirk.
