For lovers of tiny burritos and tiny pancakes comes the world’s smallest cup of coffee, made from a single bean.

In the important video demonstration above, we see director and designer Lucas Zanotto brew the mouse-sized cup of joe. On the menu today is the Kenya AA-plus Karindum bean. This very small-batch coffee requires a unique process: Zanotto grinds the bean using a nail file, boils the water using a tea light, and uses a tiny filter and jar to brew the final product.

Sadly, it’s not for sale, but we are certain Zanotto could find people to pay $4 for a cup in the right circumstances.
