I adore blackberry. I knew I would love this from jump street, and I definitely do. I had a sip of it without sweetener first, before adding some as the description recommended. It is pretty naturally sweet on its own, and because it is a honey sweetness, I used honey to add to the flavor. It was jammy and berry-y and lovely. It does have a slight dryness that is reminiscent of booze.
Plus, it tastes great on second steep, just lighter. I preferred the second steep without sweetener as the boozey aspect kind of dissipated anyway, and it just tasted like a good blackberry black tea.
