3. 操作手順
This section guides you through the daily operation of your espresso machine.
- 電源オン: Plug the machine into a 120V grounded outlet. Press the main power switch to turn on the machine. The PID display will illuminate, indicating the machine is heating up.
- 加熱時間: Allow approximately 3-5 minutes for the machine to reach optimal brewing temperature. The PID display will show the current temperature.
- エスプレッソの作り方:
- 研削: 新鮮なコーヒー豆をエスプレッソのきめ細かさになるまで挽きます。
- 投与量: Fill the 58mm portafilter basket with the desired amount of ground coffee.
- Tamping: Tamp the coffee grounds evenly with firm, consistent pressure.
- ポルタフィルターを挿入します: ポルタフィルターをグループヘッドにしっかりと挿入します。
- 醸造: Place your cup(s) under the portafilter spouts. Select your desired shot volume using the volumetric controls (single or double shot). The machine will automatically start and stop the shot based on your programmed settings.
- ミルク蒸し:
- ミルクを準備する: ステンレス製のミルクピッチャーに冷たいミルクを入れます。
- スチームを有効にする: Turn the steam knob to activate the steam wand. Purge any condensed water into the drip tray.
- スチームミルク: Immerse the steam wand tip just below the surface of the milk. Open the steam valve fully to begin steaming. Texture the milk to your desired consistency.
