    2. Measure & Prepare

    Weigh out 55 grams of freshly roasted coffee beans. Preheat the Chemex with hot water and let it sit.

    Peet's tip: No scale? Measure out 5 1/2 standard coffee scoops—or 11 tablespoons—of beans. Preheating helps the temperature stay more consistent throughout the brewing process.

    Place a paper filter with the 3-ply section facing the spout. Rinse the filter with hot water.

    Discard the water and place ground coffee into the Chemex. Place the Chemex on the scale, zero out the scale, and start a timer. Pour 100 grams of hot water (twice the weight of the grounds) in a spiral pattern so that all of the grounds are saturated. Then wait for the coffee to bloom.

    At 30 seconds, resume pouring water over the grounds, until your scale reaches 800 grams at 3 minutes. Pour first in a spiral pattern, and then straight down. It's okay to pause during your pour, but keep the coffee grounds fully saturated from start to finish.

    Peet's tip: The secret to perfect coffee is the right ratio of coffee to water—1:16, or 1g of coffee for every 16g of water.
