Good coffee at home comes down to a few basics: fresh beans, the right grind, the right amount of coffee for your water, and water at the right temperature. Get those right and almost any brewer makes a good cup. The brewer you choose then decides the style: rich and heavy, clean and bright, or strong and concentrated.
This guide covers the basics first, then each brewing method, with the grind, ratio and time for each, so you can pick one and start.
Better coffee, in four steps
These matter more than which brewer you own.
- Fresh beans: whole beans, ideally used within 2 to 4 weeks of the roast date.
- Grind just before brewing, at the size your brewer needs.
- Weigh it: start at 1:16, one gram of coffee for every 16 grams of water.
- Hot, not boiling: water at 195 to 205°F (90 to 96°C), about 30 seconds off the boil.
The Basics That Matter Most
Fresh beans
Roasted coffee is at its best from a few days to a few weeks after roasting, then slowly goes flat. Buy whole beans with a roast date on the bag, in amounts you will finish in two or three weeks, and keep them in an airtight, opaque container at room temperature. Our guides to how long coffee beans last and how to store coffee beans go into detail. Roast level changes the flavor too: see our guide to coffee roast levels.
Grind size
Ground coffee loses aroma within minutes, so grind just before you brew. Size matters as much as freshness: the shorter the contact between water and coffee, the finer the grind needs to be. Espresso, which takes about 30 seconds, needs a fine grind; a French press, which steeps for 4 minutes, needs a coarse one. Our coffee grind size chart covers every method.
Coffee-to-water ratio
Weigh your coffee and water rather than using scoops. Start at 1:16 by weight, about 15 grams of coffee for a 250-gram (8-ounce) cup, then go toward 1:15 for stronger coffee or 1:17 for lighter. Our coffee-to-water ratio guide has the numbers for each method.
Water
Coffee is about 98 percent water, so use water that tastes good on its own; filtered tap water is fine. Brew at 195 to 205°F (90 to 96°C). Boiling water can taste harsh and bitter, and water much below 195°F tends to give a sour, thin cup. More in our guide to coffee and water.
Coffee Brewing Methods at a Glance
| Method | Grind | Ratio | Time | In the cup |
|---|---|---|---|---|
| French press | Coarse | 1:16 | 4 min | Rich, full-bodied, a little sediment |
| AeroPress | Medium-fine | 1:15 | 1–2 min | Clean and concentrated |
| Clever Dripper | Medium | 1:16 | 3–4 min | Rich but clean |
| Pour-over (V60, Kalita) | Medium-fine | 1:16 | About 3 min | Clean, bright, clear flavors |
| Chemex | Medium-coarse | 1:16 | 4–5 min | Very clean and light |
| Drip coffee maker | Medium | 1:15–1:17 | 4–6 min | Balanced, easy for a crowd |
| Moka pot | Medium-fine | About 1:10 | 4–5 min | Strong, espresso-like |
| Espresso | Fine | 1:2 (coffee in to drink out) | 25–30 sec | Concentrated, with crema |
| Cold brew | Coarse | 1:5 concentrate or 1:8 ready to drink | 12–24 hours | Smooth, low in bitterness |
Ratios are coffee to water by weight. Adjust to taste: more coffee for stronger, less for lighter.
Immersion: French Press, AeroPress and Clever Dripper
Immersion brewers let the grounds sit in all the water at once, then separate them. They are forgiving, because timing and pouring technique matter less, which makes them a good place for beginners to start.
French press. Coarse grounds steep for about 4 minutes, then a metal mesh filter is pressed down. The mesh lets oils and fine particles through, so the coffee is heavy and full-bodied with a little sediment at the bottom. Try 20 g of coffee to 320 g of water. Our French press guide has the full method.
AeroPress. A plastic chamber where coffee steeps briefly and is then pushed through a paper filter by hand. It is quick, nearly unbreakable and easy to clean, and the paper filter gives a clean cup. Try 15 g of coffee to 220 g of water. See our AeroPress brew guide for the standard and inverted methods.
Clever Dripper. A cone that holds water until you set it on a mug, which opens a valve and drains the coffee through a paper filter. You get the ease of a French press with the clean cup of paper. More in our Clever Dripper guide.
Pour-Over: V60, Kalita and Chemex
Pour-over means pouring hot water by hand over grounds in a paper filter. It takes a little practice, but it gives the cleanest, brightest cup, and it is the best way to taste the differences between coffees. A gooseneck kettle makes the slow, steady pour much easier.
A basic pour-over (one mug)
15 g medium-fine coffee and 250 g water at about 200°F (93°C). Total time about 3 minutes.
- Rinse the paper filter with hot water to remove any paper taste and warm the brewer. Pour that water away.
- Add the coffee and pour about 30 to 40 g of water, roughly twice the coffee’s weight, to wet all the grounds. Wait 30 to 45 seconds while it bubbles. This is the bloom.
- Pour the rest of the water slowly in circles, keeping the level steady, until you reach 250 g.
- Let it drain. If it ran much faster than 3 minutes and tastes sour, grind finer next time; if it ran slow and tastes bitter, grind coarser.
The V60 has a cone shape with spiral ridges and a large hole, so your pouring speed controls the brew. The Kalita Wave has a flat bottom that drains more evenly and is more forgiving. The Chemex uses a thick paper filter for an especially clean, light cup and makes several cups at once. Our pour-over guide, V60 guide and Chemex guide cover each in detail, and our guide to the coffee bloom explains that first step.
Drip Coffee Makers
An automatic drip machine does a pour-over for you, and it is the easiest way to make coffee for several people. Use a medium grind and about 60 g of coffee per liter of water (roughly 1:16). The weak point of many cheap machines is water that is not hot enough; brewers certified by the Specialty Coffee Association are tested to brew in the right temperature range. Descale and clean the machine regularly, as our guide to cleaning a coffee maker explains, because old coffee oils and scale quickly make it taste stale.
Espresso and Moka Pot
Espresso forces hot water through finely ground, tightly packed coffee at high pressure. A standard double shot uses about 18 g of coffee to make about 36 g of espresso in 25 to 30 seconds. It needs an espresso machine and a good grinder, and it takes the most practice of any method, but it is the base for lattes, cappuccinos and flat whites. Start with our guide to what espresso is.
A moka pot is the low-cost alternative: a stovetop pot that pushes water up through the coffee with steam pressure. It makes strong, rich coffee, though not true espresso. Fill the basket level without packing it and use water that is already hot. Our moka pot brew guide walks through it.
Cold Brew
Cold brew steeps coarse grounds in cold or room-temperature water for many hours instead of minutes. Without heat, less bitterness comes out, so it tastes smooth and naturally sweet. Make a concentrate at 1:5 and dilute it about 1:1 with water or milk, or brew ready to drink at 1:8. Steep 12 to 18 hours on the counter or 18 to 24 hours in the fridge, strain it, and use it within a week. Our cold brew guide has the full recipe.
French Press vs AeroPress vs Chemex
| French press | AeroPress | Chemex | |
|---|---|---|---|
| How it brews | Steeps, metal mesh filter | Steeps, then pressed through paper | Pour over, thick paper filter |
| Grind | Coarse | Medium-fine | Medium-coarse |
| Time | About 4 minutes | 1–2 minutes | 4–5 minutes |
| In the cup | Full-bodied, a little sediment | Clean and concentrated | Very clean and light |
| Batch | 1–8 cups | 1 cup | 3–10 cups |
| Travel | So-so (glass breaks) | Excellent | Poor |
| Best for | Simple, bold coffee | Speed, travel, tinkering | Bright coffee for several people |
If you want the least fuss, start with a French press. If you brew one cup at a time or travel, get an AeroPress. If you love bright, delicate coffee and brew for two or more, the Chemex is worth the extra attention.
Gear Worth Buying First
- A burr grinder. The single biggest upgrade. Burrs crush coffee to an even size; blade grinders chop it unevenly, so some grounds over-extract while others under-extract. See blade vs burr grinders.
- A digital scale that reads to 0.1 g. It makes your coffee repeatable. Our roundup of coffee scales has options.
- A gooseneck kettle, if you make pour-over. The narrow spout gives you a slow, controlled pour. More in our gooseneck kettle guide.
- A water filter, if your tap water tastes of chlorine.
Quick Fixes When It Tastes Wrong
| It tastes | Usually means | Try first |
|---|---|---|
| Sour, sharp, thin | Under-extracted | Grind finer or use hotter water |
| Bitter, harsh, drying | Over-extracted | Grind coarser or shorten the brew |
| Weak and watery | Too little coffee | Use more coffee (move toward 1:15) |
| Flat, papery, dull | Stale coffee | Fresher beans, ground just before brewing |
| Muddy or gritty | Grind too fine for a mesh filter | Grind coarser, or use a paper filter |
