Espresso should be brewed in the 200ºF range. Our tests have shown that the Office Control brews consistently at 198ºF, so its right on the mark. Please note that this is the temperature of water as it exits the group head and not in cup. Due to being exposed to the air and the heat absorption that can occur from the cup itself, the in-cup temperature tends to be a bit lower. Information like brewing temperature can be found for any of the espresso machines we carry by following the link below to our Compare-O-Matic.
