2. Adding Water:
Unscrew the upper cover and fill the water tank with up to 80ml of water. You can use either cold or hot water depending on your preference and desired brewing method.
3. Brewing Coffee:
- For Hot Espresso (with cold water heating):
Place the prepared coffee adapter into the machine's brewing chamber. Screw it firmly into place. Add cold water to the tank. Press and hold the power button for 2 seconds. The machine will begin heating the water to 92°C (198°F), which typically takes 5-6 minutes for 60ml of coffee. Once heated, it will automatically extract the espresso.
- For Espresso (with pre-heated water):
Place the prepared coffee adapter into the machine's brewing chamber. Screw it firmly into place. Add hot water to the tank. Double-click the power button. The machine will immediately begin extracting the espresso.
- For Iced Coffee:
Prepare your coffee as usual. Place ice and milk (or other desired additions) into your coffee cup. Brew espresso using either the hot or cold water method directly into the cup with ice. Stir gently to combine.
