Step 3: The Brew
Once the water is in the upper chamber:
Stir the Mixture: Gently stir the coffee grounds and hot water together, allowing for the extraction of flavor, oils, and aromatic compounds. The ideal brew time ranges from 1 to 3 minutes, depending on your taste preference.
The Magic of Vacuum: As the brewing time passes and the heat source is turned off, the water in the upper chamber cools down. This cooling causes a drop in pressure, leading to the brewed coffee being drawn back down through the filter and into the lower chamber.
Step 4: Enjoying Your Coffee
Finally, the brewed coffee settles in the lower chamber, leaving behind the solid grounds in the upper chamber. Now all that’s left is to pour your freshly brewed coffee from the lower chamber into your favorite cup, savor the aroma, and enjoy the unique flavor profile produced by this fascinating method.
