Steam Wand: Frothing for Your Lattes

For those who enjoy milk-based espresso drinks like lattes and cappuccinos, the steam wand is an essential part of the espresso machine. This component creates steam for frothing and steaming milk to achieve that perfect velvety texture.

Pressure Gauges: Monitoring the Process

Pressure gauges are instrumental in ensuring that your espresso extraction process is finely tuned. These devices provide real-time feedback on the pressure levels within the machine, allowing you to make adjustments for optimal results.

Group Head: Where the Magic Begins
