Why is tea naturally sweet?

I don't get it, and I'm so curious. I'm not talking about packaged diet Nestea with artificial sweeteners; I'm talking about all natural tea bags, no sugar, no aritfical sweetners-- sweet but zero calories. It's a miracle!

anyone know this? pleaseee

Unless your talking about fruit teas I've never had a sweet tea that wasn't sweetened. 

I'm talking about teas like herbal teas and vanilla teas and roobius and chamomile. 

Green tea, chamomile tea, as well as some red teas taste sweet to me, but it`s a very subtle flavour indeed. If they taste very sweet, check the ingredients for flavourings/colourings, you don`t want any chemicals in your tea even if they call themselves 'natural'.

Probably because they have naturally sweet things in them.
