Open up filter paper and position 3 layers at the front of the Chemex spout. This prevents the paper from collapsing.
Rinse filter paper. Completely saturate with hot water to remove any papery taste.
Allow the water to warm your Chemex whilst you grind your coffee.
Grind your coffee to produce 30g. For best results, freshly ground coffee is preferred. Aim for a medium coarse grind.
Discard excess water from the Chemex.
Place Chemex onto scales and tare.
Place 30g ground coffee into Chemex. Tap to level out.
Tare scales and start timer.
Saturate coffee with 60g of water.
Wait 25 seconds for coffee to bloom. Blooming releases gasses from the coffee and allows for an even extraction.
Add a steady stream of water until you reach 390g. Aim to finish pouring at 1 minute. Pour a stream of water in a spiral, circulating in and out. Avoid the paper edge. The coffee should flow steadily.
Aim to finish extraction at 2.50 minutes. Remove filter and coffee from Chemex.
Preheat your cup with hot water. Discard. Pour coffe into your cup from Chemex.
Enjoy your coffee!
