Mathematicians are trying to make the perfect cup of coffee. It might seem strange that mathematicians are trying to do this, but coffee has 1,800 chemical components. If you combine these with the different ways of making coffee, there are a lot of numbers. The mathematicians had to use many complex calculations to find the perfect method. Researchers focused on what happens to coffee as it goes through coffee machines.

The research could change the way coffee machines are made. A researcher said he wanted, "a complete mathematical model of coffee brewing that you could use to design coffee machines, rather like we use a theory…to design racing cars". Coffee lovers might soon be able change the taste of the coffee as they filter and brew it. They could change the water temperature, the size of the ground coffee, the length of time needed to make it, and more.
