A single degree changes the taste.
+1 °C helps when a shot is under-extracted or too sour—sweetness and body will emerge.
But if you overheat, bitterness and flatness show up, especially with dark roasts.
Drill: pull one shot at your baseline temperature, then at +1 °C and −1 °C.
Taste and write down the differences.
