I often wonder would you class an energy drink as a "Soft Drink" ? A soft drink (widely referred to as pop, soda, or soda pop) is a drink that contains no alcohol but is usually referred to as a sugary drink. Soft drinks are often carbonated and commonly consumed while cold and or room temperature. ... Does it's high content of caffeine and taurine rule it out as a soft drink ? Anyone kindly share some facts on this?
