I drink mate and also mate tea with milk.. I didnt know it was popular outside argentina and uruguay?
Green tea is also good, but still not as refreshnig as an ice cold coca cola!, talking about it makes me really want to drink one actually, sounds crazy does it not?.. I never thought I could be addicted to coca-cola.. but maybe I am.
I've been drinking mate since over a decade.
A couple of years ago a soft drink based on it got famous here in germany (with hackers first, now it's everywhere), I've mostly switched to that since. I only contains 5g of sugar per 100ml, less than carrot juice!
