The cheapest kilogram of coffee is not cheap if you stop enjoying it halfway through. Work out how much you actually use before choosing the bag size. A discount is a poor reason to keep opened coffee around longer than your routine allows.
Calculate consumption from doses
Two 18 g espresso doses a day use 36 g of beans before any dialing-in or grinder losses. A 250 g bag would last about seven days at that rate; a 1 kg bag about 28. Those are arithmetic examples, not freshness deadlines. Filter coffee at 20 g a day uses a very different amount.
Use your own dose and number of brews, then add a realistic allowance for adjustments. If you make coffee only on weekends, a large opened bag has a different life from the same bag in a busy household. The brew-ratio calculator helps determine doses for your filter batches.
Look for information that survives the marketing
Check roast date, roast description and the roaster's brewing advice. A best-before date answers a packaging question but is less useful for judging when the coffee was roasted. Ask the seller if the date or recommended resting period is unclear.
No single number of days after roasting suits every roast, package and brewing method. Very fresh coffee can behave differently in espresso as it releases gas. Use the roaster's guidance and keep a record of when the bag was opened, rather than treating the newest possible roast as automatically ready to brew.
Protect the bag you are using
Keep daily beans dry, sealed and away from heat and direct light. Close the original resealable bag properly or use a clean airtight container. Do not leave a clear jar beside a sunny kettle simply because it looks attractive.
Label a container if moving beans out of the bag: coffee name, roast date and opened date. That prevents mystery leftovers from becoming the next dialing-in problem. Keep whole beans until grinding where your equipment allows it; ground coffee offers less flexibility for adjustment and storage.
Use freezing as a deliberate choice
If you freeze surplus coffee, consult the roaster's advice and package it to exclude moisture and unwanted odours. Small sealed portions are easier to manage than repeatedly opening a large cold container. Avoid condensation on beans you plan to grind by letting a sealed portion reach room temperature before opening it.
Do not make frozen storage an excuse to buy coffee you have not tried. First buy one manageable bag and establish that you enjoy it. Then decide whether buying extra and portioning it is worth the work.
Write next month's order from actual use, not from the amount that unlocked free shipping. Better purchasing often needs no new storage equipment at all.
