Brewing techniques vary by device, however some fundamental principles appy:
For best results, brew coffee using a French Press, drip coffee maker, or pour-over device such as Chemex
Grind your coffee beans with a burr grinder to a ground particle size appropriate for your brewing device
Use two (2) tablespoons (about 10 grams) of coffee per 6 ounces of water, add more or less ground coffee to suit your taste
Coffee should never be boiled, use R.O. water with minerals added (Third Wave Water, Baby Formula Water from grocery). Water should be at 200-202 degrees F for best extraction.
If you are using a French Press or Pour Over device, apply enough water to wet all the ground coffee and let the coffee bloom for 1 minute. You will see CO2 being released during this process and is THE indication that your coffee is fresh. Stale coffee will not bloom. Add remaining water after the 1 minute bloom period. Technique will vary based on device. If using a drip coffee machine, you may or may not have bloom/pulse options.
Consume your coffee within 1 hour for peak flavor.
