Quick answer: how long does coffee stay fresh?
Roasted whole coffee beans stay fresh for about 1 to 3 weeks at room temperature once opened and moved to an airtight container, according to the National Coffee Association. Ground coffee lasts 1 to 2 weeks, and frozen whole beans 3 to 4 months. Sealed bags keep until their best-by date, the NCA says, but coffee starts losing freshness almost right after roasting, so a recent roast date is worth looking for.
| Coffee | Stays fresh, per the NCA |
|---|---|
| Unopened bag of roasted beans or ground coffee | Until the best-by date |
| Pods and instant coffee | Until the best-by date |
| Whole beans, room temperature | 1 to 3 weeks |
| Whole beans, refrigerated | 2 weeks |
| Whole beans, frozen | 3 to 4 months |
| Ground coffee, room temperature | 1 to 2 weeks |
The NCA's times assume opened coffee has been moved into an airtight container. It adds that old beans are rarely unsafe unless moisture gets in and they grow mold. They simply lose aroma and taste flat or stale.
Roast date versus best-by date
A best-by date tells you when the seller thinks the sealed bag stops being at its best. A roast date tells you how old the beans are. The NCA's week counts start once a bag is opened; it says an unopened bag keeps until its best-by date. But it also says coffee begins to lose freshness almost right after roasting, so between two sealed bags, the one roasted more recently is the fresher buy.
Some Oregon roasters put this on the bag. Heart in Portland prints a roast date and batch number on every bag, by its own description. If a bag carries only a best-by date, you cannot tell how long it sat before it reached the shelf.
Is coffee too fresh on roast day?
Freshly roasted beans give off carbon dioxide for a while, a process called degassing. That is why good coffee bags have a one-way valve. For formal tasting, the Specialty Coffee Association's Standard 102-2024 says samples should rest 8 to 24 hours after roasting before they are cupped.
By that measure, a bag that arrives a day or two after roasting is ready to brew, with the NCA's 1 to 3 week window still ahead of it.
Why distance matters
Wikipedia's coffee roasting article explains that coffee tends to be roasted close to where it will be drunk, because green coffee is more stable than roasted beans. The same article puts the typical optimal shelf life of roasted coffee at two weeks, and of ground coffee at about 15 minutes. Green beans can cross an ocean. Roasted beans are on a timer.
That is the practical case for a roaster in your own state. A bag roasted in Portland, Eugene or Bend starts its two weeks near you. A few Oregon examples from the roasters we list, as their own pages describe them:
- Wandering Goat in Eugene roasts to order every week.
- Water Avenue Coffee says 90% or more of what it roasts is hand delivered to partners within 50 miles of its Portland roastery. It has been owned by Harder Day Coffee since August 2024, Willamette Week reported.
- Sterling gives customers within two miles of Northwest Portland a local discount on online orders.
- Roseline buys fresh crop coffees and treats coffee as a seasonal fruit.
How much to buy at once
The NCA's advice is to buy smaller batches more often, enough for one or two weeks. A standard 12 oz bag holds about 340 grams of coffee. At the NCA's pour-over ratio of 1 gram of coffee to 13 to 16 grams of water, that brews roughly 4.4 to 5.4 liters of coffee, our arithmetic. How long that lasts depends on your kitchen: one person drinking a mug a day goes slower than a house of three.
If a bag outlasts two weeks, split it on day one. Keep a week's worth in an airtight, opaque container in the cupboard and freeze the rest in an airtight container, as the NCA describes. Our guide to storing coffee in Oregon's climate covers the damp west side and dry Bend.
Signs your coffee is past its best
- Less smell when you open the container. The NCA says aged beans noticeably lose aroma.
- Beans that look lighter than when you bought them, which the NCA also lists.
- A flat, stale taste in a recipe that used to work. Check the date before you change your grind.
- Any sign of moisture or mold. That is the one case where the NCA treats old coffee as unsafe.
Fresh coffee from Oregon, on a schedule
The roasters named on this page are local favorites we list. A listing does not mean a roaster is part of the club.
The Multnomah Coffee Club matches the NCA's buying advice: a 12 oz bag from a different independent Oregon roaster each box, every 2 or 4 weeks, at $16.99 a bag. Our first promise is "Roasted and shipped within 3 days." Your first bag is free; you pay $7.99 shipping on that first box. Skip or cancel anytime.

Coffee freshness questions
How long do coffee beans last after opening?
About 1 to 3 weeks at room temperature in an airtight container, according to the National Coffee Association. Frozen in an airtight container, whole beans keep 3 to 4 months.
Does coffee expire?
Not in the sense of becoming unsafe, the NCA says, unless moisture gets in and it grows mold. It loses aroma and flavor over time and can taste stale.
How long should coffee rest after roasting?
For cupping, the SCA's Standard 102-2024 calls for 8 to 24 hours of rest after roasting. By that measure, a bag that reaches you a day or more after roasting is ready to brew.
Is ground coffee fresh for as long as whole beans?
No. The NCA gives ground coffee 1 to 2 weeks at room temperature, against 1 to 3 weeks for whole beans. Grind just before brewing if you can.
