It's a genuinely simple question with a genuinely simple answer, once you know the standard dose for each brewing method. A kilogram of beans doesn't stretch as far as it might seem, and knowing the real numbers is useful for budgeting whether you're buying for home or for an office.
The math, by method
Espresso, single shots: a standard dose is 7 to 9 grams, giving you roughly 110 to 140 single shots per kilogram.
Espresso, double shots: at 18 to 20 grams per double, expect roughly 50 to 55 doubles per kilogram, most cafes and home baristas now pull doubles as the standard shot.
Filter coffee: using a standard 1:16 ratio with roughly 15 to 18 grams per cup, a kilogram makes around 55 to 65 cups.
French press: at a similar 15 to 18 grams per serve, expect a comparable yield to filter, around 55 to 65 servings.
Why this matters for planning
If you're buying coffee for a household, knowing roughly 55 to 65 filter cups per kilogram makes it easy to estimate how often you'll need to restock based on how many cups your household actually drinks. For an office, the same math scales up quickly, a small team drinking filter coffee daily can work through a kilogram in well under two weeks.
A note on freshness
Coffee loses aroma quickly once ground, freshly ground coffee smells and tastes noticeably better than coffee ground even 15 to 20 minutes earlier. This is part of why grinding just before brewing, rather than buying pre-ground in bulk, makes a real difference regardless of how far your kilogram stretches.
The takeaway
A kilogram of beans makes roughly 50 to 65 servings depending on method and dose, closer to the lower end for double-shot espresso, closer to the higher end for filter and French press. Knowing your own dosing habits is the only real way to calculate it precisely for yourself.
