Tech Tip: Adjusting the Temperature/Pressure on the Rocket Giotto

While Rocket thoroughly calibrates their espresso machines prior to shipping them out, some folks have found that, over time, they can maintain their shot quality by adjusting the temperature of the water that's delivered to the brew group. Gail walks us through the process of popping open the lid of the Rocket Giotto Premium Plus and adjusting the pressure to improve the temperature -- and while we know people love to geek out and mod their machines themselves, following this process will void any warranties still on the machine. If yours is still under warranty, leave this to the pros.
