Rize or Caykur teas are pretty good Turkish teas, available in any supermarket there. The tea is grown on the Black Sea (Trabzon, for instance). It is very low in tannin and therefore doesn't get bitter easily. In Turkey they normally use the Samovar method, with the tea concentrate at the top of a water (boiling) container. After about 20m of brewing this concentrate is ready to be mixed with the water from the lower container. About 1:5 or 2:3 is what I have often seen. There is always sugar in the tea (cubes) or in the mouth before you drink it. The tea is served in small tea glasses (fit into a fist) on a small saucer. Luks means luxury, i.e. premium quality. A long time ago I read that the Turkish grown tea is low in pesticides (as opposed to the Chinese ones at that time). Unfortunately a lot of Ceylon tea is nowadays used as a substitute for proper Turkish tea (higher in tannin).
