About this personality

The Ratio Scientist

Weighs the beans. Weighs the water. Probably weighs the options.

You own a scale that reads to 0.1 g and you use it daily. You change one variable at a time, you know exactly what 1:16 means and you have opinions about water temperature. Every cup is data; the best ones become the recipe.
