Making coffee can be fun, if you know what you're doing.
Grinder: Burr grinder with adjustable grind size settings. I recommend the grinder here, but make sure that you call and get a price comparable to whatever Amazon is currently at. This grinder is a bit expensive, so it's something to shoot for but is not a "must have" to make great coffee.
Scale: If getting into specialty coffee, a scale is an extremely helpful tool to have. Find a good one buy clicking here.
French Press: Brew Process
Preheat french press with hot water (from the sink). Grind coffee on course setting, about coarse sea salt size. For a 4 cup french press, use 30 grams or about 4 tbsp. Add your ground coffee into the french press, add the water slowly and ensure that you saturate all of the grounds. Add double the grams of water as there is coffee for the bloom stage (30 grams of coffee, add 60 grams of water).
Stir gently after 30 seconds, then add the rest of the water and position to plunger in the carafe but do not plunge yet. Water amount with be 425 to 450 grams, based on your desired strength. 450 grams is perfect for most people. Let it steep for 4 to 4 1/2 minutes (based on your preference) then plunge with a delicate and consistent, slow motion right down to the bottom. Pour your brew into the cup carefully, to not agitate the coffee resting at the bottom.
Serve it right away!
