I am coming to think this is easily the best tea in the herbal sampler. It’s definitely blueberry. It’s not as tart as some of the others, even when steeped at the maximum recommended steep time. Blueberries are a bit tart to begin with so it doesn’t seem overly odd for a blueberry herbal to be tart. As opposed to some of the other herbals in this sampler where the tartness seems more out of place.
I’d already put my computer to sleep last night before I made this herbal so I couldn’t check and see how long I’d steeped it last time. I went with the maximum recommended steeping time because I remembered several of the herbals from this sampler being too light at the minimum (4 min). It stood up to the longer steeping well. A bit too tart and vaguely berried initially, as it cooled the blueberry really came out and blended well with the tartness. I may try steeping it 30 seconds less next time, but I don’t think it will need to go any lower.
