Think of a Charming Hotel: You come in, sit down at the bar and ask for a coffee. Maybe you don't realize what machine sits on the counter, but the quality of the espresso will show you: It's a Quadrant.
The Quadrant is a traditional single boiler machine that allows the manual control of drink and hot water portions. Groups with Fiamma's static pre-infusion chamber.
Pre-infusion
Group head with static pre-infusion chamber for a soft and even immersion of the coffee
Cup warming
