Time and temperature. If you break down the essentials of a good cup of coffee/shot of espresso you will arrive at two variables: time and temperature. It doesn't matter how fresh your coffee is or how expertly roasted it was. If your brewing time and temperature are not correct, you end up with something you don't want to drink. So what's the best way to control those two variables? With a PID of course. Especially on a single boiler machine, where the boiler temperature will fluctuate between brew temp and steam temp, a PID will help you dial in a delicious shot of espresso, every time. In the Morning Maintenance video below Gail will show you how to program your PID on the Rancilio Silvia. The PID's we install on the Silvia will allow you to control the brew temperature, pre-infusuion time, pre-infusion wait time, and brew time. Once you know how to program your machine, it's fun to experiment with different temperatures and times for the same coffee. Each variable will bring out different flavors in your cup! Yum!
