The typical ratio for coffee-to-water is 7.5 grams of ground coffee for every 100-150 ml (about 3.3-5 oz) of water. That is 50g-75g/L or between 1:13 to 1:20.
Good Enough
What you need:
- Freshly roasted coffee that has already been ground
- 1 tablespoon measure
- a drip coffee maker
What you do:
6 Tablespoons of coffee is a good starting point for most drip coffee makers. After that, you can vary your amount to taste.
Important note: Cup size can be deceiving. Surprisingly, most drip coffee makers consider a “cup” of coffee to be less than 8 ounces. For instance, one popular brand advertises that it makes “12 Cups” in a 60oz pot. That’s only 5oz per cup. So you need to measure your coffee and your water in order to get it “Perfect”…
Perfect
What you need:
- Freshly roasted coffee
- a kitchen scale
- a coffee grinder
- a drip coffee maker
What you do:
- Grind coffee to medium size (around the consistency of sand).
- Use a scale to measure out coffee and water for brewing; a good starting ratio is 1oz of coffee (about 3 tablespoons) for every 16oz of water (that’s 30g coffee for every 470ml of water for you metric folks).
- Add coffee to filter and water to the reservoir. Start machine and get ready to enjoy.
