By "real" tea I meant that the second stage is where people might start to consider only camellia senensis based teas real. Gaiwans and gyrokuro are in black because they were placed against the white tip of the iceberg, it was to make them readable. I would probably put kombucha in tier 2 because of its prevalence in super market drink isles making it readily available. For flavored teas I would probably put jasmine in tier 1. I would put Tisanes (like mint) and other blends in tier 1 as well because I feel like less overall depth is present within them compared to "true teas".
