Explanation of drink ratios, specifications, etymology and history: I became fascinated with the origins of coffee and how it spread across the world, as well as an interest in the different names, and the ratios of milk to coffee - if you buy a giant latte from a high street chain do they really put in a huge quantity of coffee? And wouldn't that be too much caffeine?! According to the Italian Espresso National Institute if the water is not passed through the coffee at - at least - nine bars of pressure, it's not an espresso. Coffee was introduced to England around 200 years before tea.
