This is especially true in New Zealand and Australia where coffee culture has bloomed since the development of the flat white in Melbourne in 1993. Tastes have quickly migrated from perked or instant coffee to strong expresso served with warm milk, foam, chocolate or black. caffeine is also not only in coffee you can find caffeine in tea cocoa and energy drinks.

Foods containing caffeine have been used for medicinal purposes for thousands of years. Caffeine is one of the most commonly consumed stimulants in the world. It is absorbed easily and rapidly by both the stomach and small intestine, it then circulates throughout the whole body, including the brain. Thats why that first coffee always creates a stimulating jolt and is often reffered to as a “hit”.
