A gallon! At first that sounded like a lot, but now that I think about it, I wonder if I drink that much per day--or on some days, anyway. I've never calculated my tea consumption. I know it's lower in summer, since I don't usually want a hot drink when I'm already hot, but I bet I've drunk as much as a gallon on certain days in winter....

I am almost exclusively a black tea drinker. I mostly like Indian blacks like Assam and Nilgiri, but I also love a good Yunnan.
