                                Over 205mg of caffeine can be found in some coffee shop 'Zinger' drinks, yet others contain none at all. The term 'Zinger' is used for a variety of products, from herbal teas to energy-infused beverages, meaning there is no single answer to how much caffeine is in a zinger. The caffeine content depends entirely on which product you're referring to, with options ranging from completely caffeine-free to highly caffeinated.
