Well, i have never been in Poland, and based on postings here, apparently there are few stores selling teas or serving teas. Anyone who has business in his mind and love teas could start thinking of importing teas or introduced the habit of drinking teas.
Poland has a centuries old tradition of drinking tea. Even during the communist times there were always quite a variety of teas available, usually sold under generic names (assam, ulung, madras, ceylon). Green tea and other flavored teas was unknown. It was a custom of flavoring ea with fruit preserves. People who like and know about tea will never touch tea bags, making tea is not a big ritual there, but it takes some preparation. Bergamot flavored teas (Earl Grey) were unknown, occasionally they showed up from Soviet Union, but for purists these as any other flavored teas are not real teas. I lived in the UK some time ago and think that the best of any I ever had is Marks and Sparks "Extra Strong" it is a blend of mainly Assam, and never any milk (I even strong armed my English companion not to have it with milk). Whenever I have a chance I am logging a suitcase full of this stuff.
