60 grams per litre, or 1:16.7, is the place to start
The Specialty Coffee Association writes a filter brewing ratio as grams of coffee per litre of water, and uses 60 g/L as its example. The same ratio written the other way is 16.7, because 1,000 g of water divided by 60 g of coffee is 16.7. A litre of water weighs 1,000 g, so grams on a kitchen scale work for both.
| Water | Coffee at 60 g/L | Roughly |
|---|---|---|
| 250 g | 15 g | 1 mug |
| 500 g | 30 g | 2 mugs |
| 750 g | 45 g | A small carafe |
| 1,000 g | 60 g | A full pot |
A 1-mug cone needs 15 grams, and the Melitta is the cheap start
One mug is where the arithmetic is simplest: 250 g of water, 15 g of coffee. The Melitta cone sits on the mug, comes with #2 paper filters and rates 4.8 across 1,832 ratings. Owners call it inexpensive and easy to clean, and like seeing the coffee rise in the cup so it never overflows.

Strength is a taste, and tasters split into 2 camps
No single ratio pleases everyone, according to UC Davis research the Specialty Coffee Association published. Its 118 consumer tasters fell into 2 clusters: one liked brews at about 1% dissolved solids, the other preferred stronger coffee above 1.25%. More coffee per litre pushes a cup towards the second camp.
A full litre pot needs 60 grams, and the Cosori carafe takes it
A full litre of water takes 60 g of coffee at the same ratio, so a carafe scales the mug recipe rather than changing it. The Cosori 8-cup carafe brews through a double-layer stainless steel filter, at 4.7 across 6,701 ratings. Owners say it makes consistent coffee, is easy to use and suits a budget; opinions on how long it lasts are mixed.

The Kalita Wave in size 185 sits between the two: its listing says 16 to 26 ounces, which is roughly 470 to 770 g of water, or 28 to 46 g of coffee at 60 g/L. It rates 4.5 across 1,418 ratings, the thinnest owner record here.

Water temperature matters less than the ratio
At matched strength and extraction, brew temperature barely changed the taste. UC Davis brewed the same coffee with water from 87°C to 93°C and adjusted the grind so every cup came out the same strength. Neither trained judges nor consumers found differences that mattered, according to the Specialty Coffee Association’s summary.
What a gooseneck kettle does well is pour slowly and evenly over a cone. The Cosori kettle holds 0.8 L, has 5 temperature presets and a 1-hour hold, and rates 4.6 across 19,562 ratings.

Owners like the presets, the quick heating and a handle that stays cool. The recurring complaint is reliability: some units stopped working early.
Buy it if
- A slow, steady pour over a cone
Don't buy it if
- Brewing a full pot, since it holds 0.8 L
Espresso uses a different ratio, measured in the cup
Espresso is written as a beverage ratio: the weight of the drink against the weight of the dry coffee. The Specialty Coffee Association’s example is 18 g of coffee making a 36 g shot, a beverage ratio of 2. Filter coffee sits near 15 on that scale, so a filter recipe and an espresso recipe are not interchangeable. The grind matters for both; burr against blade grinders explains why.
