Around 60 million coffee machines are sold each year. A coffee machine is great for creating a quick drink with a fairly consistent taste, meaning the coffee produced should taste the same each time.

There’s many factors which can influence the variation in a coffee’s flavour: water quality, ratio of coffee to water, temperature. This study focused on the extent to which coffee beans were ground and how this impacted the flavour, and how what implications this would have on industry.
