Every coffee lover asks this question sooner or later. You buy a 1 kg bag of whole bean coffee, look at those beautiful beans and think: how long will this actually last me? Good question. The answer isn’t as simple as it sounds, because it all depends on how you brew, how much you dose, and how strong you like it.
How many cups do you get from 1 kg of whole bean coffee?
Purely on paper, 1 kg of coffee (that’s 1,000 g) gets you somewhere between 110 and 140 espressos. A single espresso is usually 7-9 g of coffee, and a double takes 14-18 g. But you know how it is: nobody at home weighs to the gram. Some days you dose a bit more, some a bit less, so in real terms a kilogram lasts one person about a month to six weeks, if you’re making 2-3 coffees a day. In a café, the rule of thumb is that 1 kg gets you 70-80 coffee drinks.
How does your brewing method affect how fast a 1 kg bag goes?
- Espresso / bean-to-cup machine: about 7-9 g per cup
- Moka pot: around 10-12 g, though this depends on the size of the pot and how firmly you pack it
- French press / drip / filter: 6-8 g per 100 ml, so if you drink from big 250 ml mugs that works out at around 15-20 g a serving, though personally I grind 30-46 g every morning for my own filter brew
So the gentler the brewing method, the less coffee it uses. Espresso eats through the most, but it also gives you the most concentrated flavour.
How long does a kilogram of whole bean coffee actually last?
To put it simply:
- 2 espressos a day: a kilogram lasts around 2 months
- 3 cappuccinos a day (so 3 double espressos): around 3 weeks
- an office with a machine, where coffee flows non-stop: 1 kg a day is genuinely not a joke
Most Colbergcoffee customers describe a 1 kg bag as a safe month’s supply: the coffee doesn’t go stale before you finish it, and you don’t run out too soon either. There’s usually enough left over for when friends drop by at the weekend.
How to store a 1 kg bag of whole bean coffee so it stays fresh
If you’re buying 1 kg at a time, storing it properly matters. Keep it in a sealed container, away from light and moisture. Not in the fridge. Coffee soaks up smells and moisture like a sponge. As soon as you open the bag, reseal the zip straight away and just leave the coffee in its original bag with the one-way valve.
The short version
- 1 kg of coffee = around 110-140 espressos
- Lasts 3-6 weeks, depending on how many coffees you drink a day
- Espresso uses more per cup than filter does
- Better to buy smaller amounts more often than stock up for six months
Want to be sure your kilogram doesn’t disappear too fast? Choose 1 kg whole bean coffee from a roastery that roasts to order, like Colbergcoffee. That way every cup is actually worth it.
Frequently asked questions about 1 kg whole bean coffee
How do you store whole bean coffee so it doesn’t lose its aroma?
Keep it in a sealed, opaque container, away from light and moisture. Coffee doesn’t like the fridge, because it absorbs smells. If you’ve got a 1 kg bag, decant part of it into your grinder’s hopper and leave the rest sealed in the original bag with its one-way valve.
How many coffees can you brew from 1 kg of whole bean coffee?
On average, 1 kg of beans makes 90-140 espressos, depending on how much you dose per cup. If you’re making cappuccinos or lattes with a double shot, a kilogram will comfortably cover around three weeks of daily drinking.
Which 1 kg whole bean coffee from a roastery is best?
The best one is freshly roasted and suited to how you actually drink your coffee. If you like classic espresso, go for the Captain’s Blend. Looking for nutty notes, try our El Salvador or India. At Colbergcoffee we roast in small batches, so you always get a fresh product.
Where can you buy 1 kg whole bean coffee?
Most reliably straight from a small-batch roastery, such as Colbergcoffee. That way you get freshness, a clear roast date and the full flavour profile. Our own shop is online, so ordering is quick and easy.
Does a 1 kg bag work for a bean-to-cup machine?
Yes. A 1 kg bag is a great option for a bean-to-cup machine, especially if you brew every day. Just keep it somewhere dry and grind it right before brewing.
Is a 1 kg bag a good choice for a single person?
Definitely. If you drink 2-3 coffees a day, a kilogram will last about a month. The key is storage: a sealed container and no light will keep the aroma intact for several weeks after opening.
