Thanks, Ian and Julie—-I too have been able to buy Yorkshire tea in unlikely places, although I cannot recall specifics at the moment.
Update on our trip, now that we are back home: our penultimate three Italian hotels of the trip were in the Dolomites (in Val Gardena, Dobbiaco, and Alta Badia). At each of those, English Breakfast tea was on offer at the breakfast buffet. Then we stayed 5nights in an apartment in Bologna, and I was able to buy English Breakfast tea at the local grocery (although I cannot recall the brand). Fortunately I had extra teabags, as the hotel in Venice, our last stop before flying to London, offered only Earl Grey in the room tea service.
After a short week at home, we flew to California to visit our kids and grandchildren. In San Francisco, our room had a tea kettle but no way to make coffee, so we walked up the street to a nearby local coffee café we knew, to get my husband his morning cappuccino. I decided to be sociable and order my beverage as well, made the mistake of ordering “black tea” (as I was running low on teabags at this point) and did not discover until we returned to our room and I removed the lid that it was—-guess what—-Early Grey.
So it is happening here in the US too.
Now I am starting to plan a trip to Japan, for a year from now, and I will be sure to put my own tea on the packing list!
