What's inside
Brew better with the bag you already have.
Start with the ratio, then adjust one thing at a time. Good coffee is not fragile, but it does ask you to pay attention.
Clean and bright
Pour-over
Use 1 part coffee to 16 parts water. Start with a medium-fine grind, water just off boil, and a slow pour that keeps the bed evenly wet.
Good start: 22g coffee and 350g water. If the cup tastes sharp or thin, grind a little finer. If it tastes dry or bitter, grind a little coarser.
Full and forgiving
French press
Use 1 part coffee to 15 parts water. Grind coarse, steep about 4 minutes, stir the crust, then let it settle before pouring.
Do not force the plunger hard through the coffee. Press gently to the surface and pour with a steady hand. Less sludge, better cup.
The machine you own
Auto drip
Use 1 part coffee to 16 parts water. A medium grind is usually right. Rinse the filter if you can, and do not be afraid to use enough coffee.
Most weak coffee is not a roast problem. It is too little coffee, too much water, or a grind that is too coarse for the brewer.
Strong, quick, travel-ready
AeroPress
Use 15g coffee and 220g water. Grind medium-fine, stir well, steep 60 to 90 seconds, and press slowly.
AeroPress is flexible. If it tastes too sharp, lengthen the steep or grind finer. If it gets muddy and heavy, back off a little.
Slow and low-acid
Cold brew
Use 1 part coffee to 8 parts water for concentrate. Grind coarse, steep 12 to 16 hours, strain, then dilute to taste.
Cold brew hides some brightness and brings out chocolate, body, and sweetness. It is good for darker roasts and hot days.
The thing people skip
Water
If your coffee tastes flat no matter what you do, try different water before you blame the beans.
Good water should taste clean on its own. Very hard, very soft, or heavily treated water can make good coffee taste tired.
If it tastes sour Grind finer, brew hotter, or give it more contact time.
If it tastes bitter Grind coarser, shorten the brew, or use slightly cooler water.
If it tastes weak Use more coffee. That solves more cups than people think.
