A 1kg bag makes roughly 45–65 coffees for most home brewers. The exact number is set by the dose you use for each drink, not by the size of the cup.
An 18g espresso dose gives about 55 double espressos from 1kg before dialling-in and bench waste. Filter at 15g per 250ml cup is closer to 66 cups. The tables below compare doses, brewing methods and realistic wastage so you can estimate how long the bag will last.
The quick calculation
Use this formula:
1,000g ÷ dose per coffee = number of coffees
| Coffee dose | Approximate coffees from 1kg |
|---|---|
| 15g | 66 |
| 16g | 62 |
| 17g | 58 |
| 18g | 55 |
| 20g | 50 |
| 22g | 45 |
The table is theoretical. A little coffee is normally lost while adjusting a grinder, purging retained grounds or spilling the one scoop that was apparently determined to land on the bench. For the grams and water you actually put in, use how much coffee per cup — espresso is coffee in to beverage out; filter is coffee to brewing water added.
How many espresso coffees from 1kg?
Many home espresso baskets are used with 18–20g of coffee. At those doses:
- 18g gives about 55 coffees;
- 20g gives 50 coffees; and
- 22g gives about 45 coffees.
These numbers refer to doses, not cups of liquid. A flat white, long black and cappuccino can all begin with the same espresso dose. Adding milk or water changes the drink, but it does not use more beans unless you add another shot.
If your basket is designed for a smaller or larger dose, use the basket's intended range and calculate from that. Overfilling a basket to chase a stronger drink can create uneven flow and make the result worse rather than stronger.
How many filter coffees from 1kg?
A useful starting ratio for filter coffee is around 60g per litre of water. That works out to 15g for a 250ml cup:
- 250ml cup at 15g: about 66 cups per kilogram;
- 300ml mug at 18g: about 55 mugs per kilogram; and
- 500ml batch at 30g: about 33 half-litre brews per kilogram.
The ratio stays the same as the batch grows. If you brew one litre with 60g and split it between four people, the kilogram still produces about 16 full one-litre batches, or roughly 66 quarter-litre serves.
Pour-over, French press and AeroPress
The method matters less than the dose.
| Method | Practical starting dose | Approximate serves from 1kg |
|---|---|---|
| Pour-over, 250ml | 15–17g | 58–66 |
| French press, 250ml | 15–17g | 58–66 |
| AeroPress | 14–18g | 55–71 |
| Batch brewer, 1 litre | 60g | 16 full batches |
These are starting points, not rules. Your brewer, grinder and preferred strength may lead you to a different dose. Change one variable at a time and keep the recipe that tastes right.
How long will a 1kg bag last?
Divide the number of coffees by the number your household makes each day.
| Household use | At 18g per coffee | Approximate duration |
|---|---|---|
| 1 coffee/day | 55 coffees | 55 days |
| 2 coffees/day | 55 coffees | 27 days |
| 3 coffees/day | 55 coffees | 18 days |
| 4 coffees/day | 55 coffees | 13 days |
| 6 coffees/day | 55 coffees | 9 days |
If two people each drink two coffees a day, a 1kg bag used at 18g per coffee lasts about 13 days. That is often a more useful buying calculation than comparing the sticker price of different bag sizes.
Allow for dialling-in
A new coffee may need a few test shots before the grind and dose suit your machine. If four 18g doses are used while dialling in, that is 72g, leaving 928g for drinking. At the same dose, the practical yield becomes about 51 coffees rather than 55.
That does not mean the coffee was wasted if each test teaches you what to change. It does mean a theoretical yield should not be treated as a promise.
To reduce waste:
- keep the dose consistent while adjusting grind;
- make one change at a time;
- write down the setting that worked; and
- expect a new bag to behave differently from beans that have been open for weeks.
Is a 1kg bag right for you?
A kilogram makes sense when your household will use it while the coffee still suits your taste. A smaller bag can be the better choice for one occasional coffee drinker or anyone who likes changing coffees frequently.
Choose the bag size from your actual dose and daily use:
- Weigh the coffee used in one normal brew.
- Divide 1,000 by that dose.
- Divide the result by the household's daily coffees.
That gives a realistic number of days for your kitchen.
