When I was in Macedonia, community and friendships revolved around coffee -- Turkish coffee in the villages and espressos in the cities. I thought that was a near-universal aspect of life outside the US, so I tried to build up my tolerance for caffeine before leaving Washington DC for Kazakhstan. I was a bit surprised to learn that it's tea culture in Central Asia, black tea or green tea are commonly offered at meetings and as part of lunch deals at restaurants.
I'm not a fan of the flavor of tea, especially green tea which seems more bitter. Black tea is fine with a few cubes of sugar. It would probably be a bit embarrassing to put as many sugar cubes into green tea as I would need to make it drinkable. However, I've learned that adding milk to tea can create a nice taste, so I occasionally ask for that when I'm offered tea.
During one of our meetings in Aktobe, we were offered tea and graciously accepted. One of the ladies in the office prepared two cups for my colleague, Elvira, and me. Elvira took the first cup, and I took the second. Both had milk, so I didn't think anything of it. Just as I was about to take my first sip of the tea, the woman who had prepared the tea reacted like she realized that she had accidentally poisoned me. I was about to drink green tea with milk.
The woman was clearly embarrassed and troubled by the fact that she had mistakenly offered me such a foul concoction, but I certainly didn't know any different. I told her it was no problem, and I drank it anyway. I thought it was pretty good, actually. Almost a reason to drink green tea.
Afterwards, I was curious to know what the big deal was. People put milk in tea all the time. Elvira said that green tea is only for people who are dieting. I hadn't heard that before, but it also didn't seem to account for the woman's reaction when she realized that I was about to drink it.
Back at the office, I asked some of my local friends. When I asked if they had ever tried green tea with milk, they all gave a face like it was something that wouldn't taste good at all and said that they just don't go together. Of course, they hadn't tried it, so they didn't really know what it tastes like.
One of my friends gave me a more thorough and reasonable explanation (though she had never tried green tea with milk either). She said that black tea leaves and green tea leaves are prepared differently. Black tea is roasted, and green tea is dried. Because of these different preparation methods, milk sours when added to green tea.
Of course, since no one had actually tried green tea with milk in it, one could think that these explanations are just rationalizations for a cultural belief that no one really understands. One of my goals now is to get one of my local friends to try green tea with milk and see what they say.
