How to make better coffee in a drip machine

Measure the coffee, grind fresh, use clean water. The machine does the rest.

An automatic drip machine is the coffee maker most people have. It heats water and sprinkles it over ground coffee in a paper filter, and the coffee drips into a carafe. It does most of the work for you, but it still rewards a little care. The biggest improvements come from measuring the coffee, grinding fresh, and using clean water, not from buying a pricier machine.

What you need

• A drip coffee maker and its filters (flat-bottom or cone, whichever your basket takes)
• Whole beans and a grinder
• A kitchen scale that reads in grams (most can switch from ounces)
• Fresh, cold, filtered water. The National Coffee Association says to avoid distilled or softened water.

Sources give a range, from about 1:16 to about 1:18. The Specialty Coffee Association's "Gold Cup" standard, as retailers describe it, is about 55 g per liter (1.9 oz). Start at 60 g and move up or down.

Step by step

1. Rinse the filter. Put the paper filter in the basket and run a little hot water through it. Pour that water out of the carafe. This removes the papery taste and warms the carafe.
2. Fill the reservoir. Add cold, filtered water. Measure by weight once, then mark your carafe or note the line.
3. Grind and weigh. Grind the beans right before brewing. Weigh them on the scale and pour them into the filter. Shake the basket gently so the bed sits level.
4. Brew. Close the lid and start the machine. If yours has a "bloom" or pre-wet setting, use it. It lets the grounds release gas before the main brew.
5. Stir and serve. When it finishes, give the carafe a quick swirl, because the first and last drips differ in strength. Pour.

If it doesn't taste right

Change only one thing at a time, so you know what made the difference.

• Bitter or harsh: the grind may be too fine. Grind coarser, or use slightly less coffee.
• Sour, flat, or watery: try a finer grind, or add more coffee.
• Weak but not sour: add a little more coffee, about 5 g (0.2 oz) per liter at a time.
• Overflow or slow drip: the grind may be too fine and clogging the filter, or the basket is overfilled. Grind coarser and check the fill.

Tips that make a bigger difference than gear

• Buy fresh beans. Look for a roast date on the bag, not just a best-by date.
• Grind right before you brew. Ground coffee goes stale within minutes, not days.
• Clean the machine. Coffee oils and mineral scale build up and make every pot taste worse. Wash the carafe and basket after each use, and descale as the manufacturer recommends.
• Weigh, don't scoop. Scoops vary with the roast and grind. A scale makes the next pot match this one.

This guide describes a widely used starting method, not a single correct way. Machines, beans, and water all vary, so treat the numbers as a starting point and adjust to your taste. The Specialty Coffee Association's own standard is behind a membership wall, so the Gold Cup figure comes from retailers describing it.
