Espresso Perfetto

For those who like a supercharged burst of caffeine there is nothing better than an espresso. However, a group of American scientists claim to have cracked the secret of making a perfect espresso. The key ingredient is something that should be added before the beans are ground.

The scientists have found that when coffee is ground, the friction between the beans creates electricity, causing particles to lump together in the grinder. By adding water to the process reduces the amount of electricity produced, resulting in less coffee waste, stronger flavours and a tastier and more drink.

Their next goal is to crack the perfect cup of coffee.

More power to their elbow!
