Choose between convenience and control while accounting for brewing method and storage.
Whole beans offer control
Grinding close to brewing lets you match particle size to the method and reduces the time ground coffee is exposed to air.
Ground coffee is convenient
Pre-ground coffee removes equipment and cleanup, but the selected grind must suit the brewer. Buy quantities that can be used while flavour remains acceptable.
Storage still matters
Keep coffee sealed, dry and away from heat and direct light. Large packs only save money when they can be used before quality declines.
Practical checklist
Check that the grind suits the brewer.
Compare bags by weight after calculating monthly use.

Questions and answers
How does Whole Bean vs Ground Coffee work?
Enter water mass and the recipe’s water-to-coffee ratio. Coffee = water mass ÷ ratio. This plans brew inputs, not finished drink yield; water retained by grounds is not estimated. Espresso uses a different convention, so do not substitute beverage yield for water here.
What does the worked example show?
Inputs: Water mass: 500 g; Water per gram of coffee: 16 g/g. Result: Coffee required: 31.25 g.
What should I check before using the result?
Coffee = water mass ÷ ratio. This plans brew inputs, not finished drink yield; water retained by grounds is not estimated. Espresso uses a different convention, so do not substitute beverage yield for water here.

Questions and answers
How is this example calculated?
Coffee = water mass ÷ ratio. This plans brew inputs, not finished drink yield; water retained by grounds is not estimated. Espresso uses a different convention, so do not substitute beverage yield for water here. In the displayed example, Water mass: 500 g; Water per gram of coffee: 16 g/g. The calculated outputs are Coffee required: 31.25 g. Keep the labels and units with these numbers: they describe this particular combination of inputs, not a result that can be reused after the measurements or assumptions change.
What changes when I edit Water mass?
The table isolates that input while keeping the other displayed settings fixed. For Water mass: 250 g, the result is Coffee required: 15.625 g; for Water mass: 1500 g, it is Coffee required: 93.75 g. Those values come from the same calculator used on this page. They show the effect of changing the input, rather than prescribing which input is right for your own task.
How should I use the different result figures?
Read each named quantity separately: Coffee required: 31.25 g. A value with a different label or unit answers a different part of the calculation. Check the measurements and assumptions before using any figure. The reference cases explain the arithmetic under their stated conditions; they do not verify a product label, a recipe or the conditions of a particular project.
