If your coffee is different every morning - strong one day, thin the next - the problem is almost never the coffee or the brewer. It is how much coffee you use for how much water. Get that ratio right and keep it steady, and most of your coffee problems go away. Here is where to start and how to adjust it to your taste.
What the ratio means
The coffee-to-water ratio is how much ground coffee you use for a given amount of water. It is usually written as a pair of numbers, like 1:16. That means one gram of coffee for every 16 grams of water.
You do not need to think in grams to use it. The point is to pick one ratio, stick to it, and change it on purpose rather than by accident.
A good starting point
For most brewing at home, start at about 1:16. That is roughly:
- 15 grams of coffee for 250 ml of water, which is one mug
- about two level tablespoons of ground coffee per mug
That gives a cup that is neither weak nor heavy, and it is the right place to begin adjusting from.
Pick one ratio, write it down, and change only one thing at a time.
Ratios by brewer
Different brewers suit slightly different ratios. These are starting points, not rules.
French press
Around 1:15. A little more coffee than pour-over, because the coarse grind extracts more slowly. For two mugs, about four tablespoons.
Pour-over
Around 1:16. Clean and balanced. About two tablespoons per mug.
Moka pot
The pot decides for you. Fill the basket level and the water to just below the valve. The ratio is built into the design, which is why a moka pot gives a short, strong coffee.
Cold brew concentrate
Much stronger: around one cup of coarse coffee to four cups of water. You dilute it when you drink it.
Iced coffee made hot
Use the same amount of coffee as usual but about half the water, because the ice adds the rest as it melts.
Spoons or a scale?
A scale is more accurate, because different coffees and different grinds take up different amounts of space in a spoon. But you do not need one to get consistent coffee.
If you use spoons:
- Use the same spoon every time.
- Use level spoons, not heaped ones.
- Use the same mug to measure water.
That alone will make your coffee far more consistent than guessing. If you find yourself adjusting a lot, a cheap kitchen scale is the most useful thing you can buy.
How to adjust to your taste
Taste first, then adjust.
- Too strong or heavy: use a little less coffee, or a little more water.
- Too weak or thin: use a little more coffee.
- Bitter and harsh: often the grind is too fine or it brewed too long, not the ratio. Check the grind first. Our post on choosing the right grind helps.
- Sour and sharp: often the grind is too coarse or the water was not hot enough.
Change one thing at a time. If you change the ratio and the grind together, you will not know which helped.
The coffee matters too
The same ratio tastes different with different coffees.
A light, bright coffee like Colombia, with orange and plum notes, can taste thin at a weak ratio, so give it the full amount. A heavy coffee like Vietnam - a Robusta, earthy and roasted - can taste overpowering at a strong ratio, so you might use a little less.
If you are starting out and want one coffee to set your ratio with, Brazil Rio Minas is forgiving. It is nutty and milk chocolate, low in acid, and good black or with milk, so small mistakes in the ratio do not ruin the cup.
Freshness changes the ratio
Stale coffee tastes weaker, so people add more of it to compensate. In a humid city, ground coffee goes stale faster than you might expect. If you have to keep adding more coffee to get the same taste, the bag may be past its best. Our post on keeping coffee fresh in Pakistani heat has the details.
Set your ratio this week
Start at two level tablespoons per mug, taste, and adjust one step at a time until it is right. Write it down so tomorrow's cup matches today's. If you want a forgiving coffee to set it with, order Brazil Rio Minas, ground for your brewer, delivered across Pakistan with cash on delivery.
