Do you reuse tea bags?

[Owlie]

It really depends on the kind of tea. Check for instructions, either on the package or at the shop. My favorite Gyokuro steeps for 45 seconds at 145°. Most of them get bitter if they steep too long, I think, but for some reason, that doesn't happen with successive steeping.

What is it? I've been itching to try gyokuro for a while, now.

I don't reuse tea bags. I find that because they're such small particles, they tend to loose flavor fast and just become nasty--bitter without other flavors in there. I'll make an exception for full-leaf filter bags, though.
I do reuse loose tea, though. I get three steeps out of my jasmine pearl (only green tea I have), and two to three out of my white and oolong teas. I like mine relatively strong (I add about 25% more leaves than they tell you to), so I get fewer steeps out of it.
