Ti-Tonics is a new tea based drink - just launched I think. I have not tried it - but will if I see it.
There seems to be a few tea based drinks around these days - such as http://teza.co.nz - and international offerings from the likes of Dilmah (complete with million dollar Hugh Jackman TVC's).
I like the simple (simple but very classy) packaging design and the elegant bottle.
Although it is reduced in sugar - it has quite a large bottle (350ml).
The "message" focuses on the benefits of the anti-oxidants contained in the tea. The website focuses on "Polyphenols" - which are good for you.
I'm into the whole - functional drinks thing. By "functional" I mean - the drinks taste good - fits into a modern life - and has beneficial properties (without looking like hippy juice).
