You've probably opened a bag of grocery-store coffee at some point and noticed it tastes flat — papery, slightly stale, like the idea of coffee more than the thing itself. There's usually a reason. Look at the bag. If you can find a roast date at all (most don't print one), it's often eight to twelve weeks behind you.
Coffee is an agricultural product with a short flavour window. "Roasted weekly" isn't a marketing line for us — it's the operating constraint that keeps the cup tasting like the lot we sourced. Here's what's actually happening in the days after roast, and why we ship within 5 days of pulling beans off the roaster.
Coffee is alive after it's roasted
When green coffee hits the drum, a long list of reactions kicks off: Maillard browning, caramelisation of sugars, the development of hundreds of volatile aromatic compounds. Roasting also traps a large amount of CO2 inside the bean structure. That trapped gas is what makes a fresh bag of coffee bloom violently when you pour hot water over the grounds.
The bean continues to release CO2 for weeks. This process — called degassing — is the single biggest variable in how a coffee tastes during its first month off the roaster.
The degassing curve, in plain language
For the first 24–72 hours after roast, coffee is too gassy to brew well. Espresso shots gush and channel. Pour overs taste muddy, with a flat finish. The bean is dumping CO2 so quickly that water can't make proper contact with the grounds.
Then the curve flattens. From roughly day 4 onward, the rate of CO2 release slows, the volatile aromatics stabilise, and the cup opens up. This is the window the SCA (Specialty Coffee Association) refers to in their cupping protocol — they recommend resting filter-roast coffees 4 to 14 days post-roast for evaluation, and 5 to 21 days for espresso roasts.
After that window, coffee doesn't go "bad" in a food-safety sense — it just gets quieter. Aromatics fade. Acidity dulls. By 6–8 weeks, even a great lot tastes generic. By 12 weeks, it's the grocery-store experience.
Why the shipping window matters
Here's the math we work with. If we roast on Tuesday and ship Friday, your bag is shipped at day 3. Standard ground shipping inside Canada takes 2–5 business days. That puts the bag on your counter somewhere between day 5 and day 8 — squarely inside the SCA's filter rest window, with weeks of good drinking ahead.
If we roasted on Friday and shipped the following Wednesday (a not-uncommon cadence for larger roasters), the bag arrives at day 7–11. Still drinkable, but you've burned half the peak window in transit.
This is why we don't carry roasted inventory longer than 7 days. Anything older gets pulled, brewed in-house, or donated. We'd rather roast more often than have weeks of buffer stock sitting at the warehouse.
What "fresh" doesn't mean
A bag roasted yesterday isn't necessarily better than one roasted six days ago. In fact, for most home brewers, day 6 will taste better than day 1. Fresh-off-the-roaster coffee is hard to dial in — too much CO2, jagged extraction, and the most expressive aromatics haven't bloomed yet.
If you've ever bought coffee at a roastery the day it came out of the drum and felt disappointed, this is why. The bag wasn't bad; you opened it too early. Let it sit on the counter for three more days and try again.
How we time our week
Roast Tuesday. Pack Wednesday. Ship Wednesday and Friday. Repeat. Limited Editions and large subscription pulls sometimes get a Thursday roast. Every bag we send has the roast date stamped on the seal — open it and check.
For our subscriptions (The Daily, The Rotation, The Numbered), we time the pull so that the bag in your hand is between 3 and 7 days post-roast on the day it lands.
Storing coffee at home so the work isn't wasted
Three things kill coffee faster than time alone: oxygen, light, and heat. The bag we ship in is opaque and one-way-valved (the valve lets CO2 out without letting O2 in), which is most of the battle. Once you open it, do the following:
- Reseal tightly after every use. Air is the enemy.
- Store the bag in a cupboard, not on the counter. Avoid direct sunlight and the heat from your kettle.
- Skip the fridge. Refrigeration cycles condense moisture inside the bag — bad for the bean. Skip the freezer too unless you're storing unopened bags for the long haul (in which case, freeze whole-bean, thaw fully before opening).
- Buy what you'll drink in 3–4 weeks. Two 340g bags spaced two weeks apart beats one 1lb bag for most households.
If you're drinking coffee daily and want the shortest possible roast-to-cup chain, a subscription is genuinely the answer — not because we're selling them, but because the bag is timed to your usage instead of sitting on a shelf.
Frequently asked
Is coffee with a roast date older than 30 days bad?
Not bad — just past peak. It'll still brew a drinkable cup, especially if it was sealed and stored well. You'll notice less complexity and a flatter finish compared to the same bean at day 10.
Why do you ship Wednesday and Friday, not Monday?
We roast Tuesday. Coffee shipped Monday would be from the prior week's roast (day 6–7), which is fine but eats into your window. Wednesday gives a 1-day rest and Friday gives a 3-day rest before transit — both inside the sweet spot.
Should I let the bag sit before I open it?
If it arrives less than 5 days post-roast and you're brewing espresso, yes — give it another 2–4 days. For filter brewing, you can open it the day it arrives.
Does the freezer extend coffee shelf life?
Yes, but only for sealed bags. Freezing whole-bean coffee in its original valve bag, fully sealed, slows aromatic loss significantly. Thaw the bag at room temperature for several hours before opening to prevent condensation. Once opened, treat it like fresh coffee.
What's the best way to tell if my coffee is past its prime?
Smell the dry grounds. Fresh coffee has a vivid, layered aroma — fruit, chocolate, flowers depending on the bean. Stale coffee smells dull and cardboard-y. Brewed, it'll taste flat in the finish and lack the brightness the roaster intended.
