A smart precision brew machine showing real-time PID temperature data on its digital screen
Temperature stability is the unsung hero of great coffee. This blog dives into how PID (Proportional-Integral-Derivative) technology in modern coffee machines maintains the ideal 92-95℃ brewing range, eliminating bitter over-extraction or weak under-extraction. We compare machines with and without PID control, share real brewing tests, and explain why this feature is a game-changer for both home baristas and casual users .
