Leaves a powdery residue at the bottom of your cup

I just finished my Stash brand box of mint #tea and thought I would give this a go since the only ingredient was peppermint leaves, but not all mint teas are created equal! This one doesn’t taste as good; makes fewer cups of tea per bag and worst bit for me is it leaves a lot more residue in the bottom of my mug. I would not recommend this brand for mint tea and I will most definitely not buy it again for myself. The savings of a few cents to a dollar or two is not worth it, in this case brand does matter.
