Why ratio, temperature, and dose matter
Most of what separates an average cup from a good one comes down to a few measurable variables: how much coffee you use, how much water you use, how hot the water is, and how long the coffee stays in contact with it. Measuring those variables makes your results repeatable, so when a cup turns out well you can make it again.
