Apparently, Caffè Nero’s “Chai Latte” is 99% caffeine free. This presumably means that it’s 1% caffeine full, i.e. 1% of it (by mass, I guess) is caffeine. This means that in a typical 300ml cup, there is approximately 3g of caffeine.

Now, your average cup of coffee (made with two shots of espresso) contains on average about 150mg of caffeine. http://bit.ly/vGY8A1 This means that one Caffè Nero “Chai Latte” is equivalent to TWENTY double espressos.
Is anyone else concerned?
