I brewed this weak (lower temperature) and really enjoyed it. Really smooth blood orange taste with a mild/medium taste of earl grey. I like it this way, it blends quite well. I’m not sure what kind of black tea it is that this Japanese company uses, but it brewed nicely with water at 190. I’ll try it with hotter water one morning to see if the earl grey comes out more (I doubt it would, but I also like it on the mild side)
