Buying coffee by the kilo
A 1kg bag is the cheapest way to drink specialty coffee per cup, and ideal for households, offices or anyone getting through 250g a week. The trade-off is freshness: coffee is best within a month of roasting, so only buy big if you’ll drink it in time. Store it sealed and dark, and consider decanting into smaller airtight jars. The kilo format is also where per-kilo comparison bites hardest: roasters usually price a 1kg bag well below four times their 250g price, because packaging, postage and handling are spread across more coffee — that gap, not the sticker price, is the saving this list is built to surface.
Frequently asked questions
- How many cups of coffee is 1kg?
- Around 55–60 double espressos at a 17g dose, or roughly 65 mugs of filter at 15g a cup. For a two-cup-a-day household that’s about a month of coffee — conveniently, also about how long beans stay at their best once the bag is open.
- Why are 1kg coffee bags better value?
- Roasting, packing and posting one kilo costs a roaster much less than doing the same four times over in 250g bags, and kilo formats are often priced with cafés and offices in mind. That efficiency shows up as a lower price per kilo — which is exactly the figure this page ranks on.
- Does a 1kg bag of coffee go stale?
- It can if it sits open. Coffee is at its best for around a month after roasting. If you won’t finish a kilo in 4–6 weeks, buy whole bean (it stales slower than ground) and keep it sealed and cool.
- How should I store a 1kg bag of coffee?
- Keep it airtight, opaque and away from heat. Don’t refrigerate opened coffee — it absorbs moisture and odours. Decanting into a couple of smaller sealed jars limits how much air the bulk is exposed to.
