Advice sought!

My brother, who loves all sorts of tea, spends time in different parts of the globe for work. For Christmas, I want to curate a collection of tea from places he’s been, either by purchasing a native brand or by creating a blend at Adagio.

Japan, England, and Hawaii should be fairly simple, though if people have ideas I’ll take them. Any suggestions for Israel, Turkey, Zurich, south Texas, San Diego?
