Tea is a nice alternative to water, and I say this as someone who doesn't like most drinks other than water.
There's a huge variety of tastes among green teas, white teas, oolong, black teas... Specific tea variety, different locations where the plants are grown, different manipulations, all concur to a lot of different tastes. However, a lot of people I've met just say it tastes like "earthy/dirty water"
And a lot of those are not "tea" (with theine/caffeine), they're herb infusions such as mint, hibiscus, chamomile, etc. You can drink as much as you want without getting the typical caffeine buzz.
I particularly like the Morocco Mint & Spices that Lipton sells.
Also, caffeine is addictive. As someone who is severely addicted to caffeine, I really recommend not getting addicted. Try to drink tea without caffeine, even if you "don't mind" the caffeine in black/green/white tea.
