As for me, I prefer Ceylon tea.
Most Russians prefer drinking black tea. I think most of us like tea that is strong and hot and prefer leaf tea over tea in sachets. I drink tea without sugar, but usually people put some sugar into their tea, or honey. Some like to add a slice of lemon.
As for tea produced in the exUSSR - Georgia used to grow tea and Krasnodar region also. Krasnodar tea actually was not that bad.
