Rize vs Gilan

Two coastal strips where a mountain range wrings rain out of sea air, producing tea country in countries that are otherwise too dry for it. Both supply enormous domestic tea cultures and almost nothing to the export market.

The short answer

These are two of the largest tea cultures in the world by consumption and two of the smallest by export presence, which is why they are almost absent from English-language tea writing. The preparation method in both cases was designed around a tea that is brewed strong and diluted to order, and the leaf is made to suit it.
