One of the biggest complaints you'll hear from your colleagues in the office is around the quality of coffee. Often the machine is at fault. Low-quality bean-to-cup machines that aren't properly cared for don't often produce high-quality drinks.
However, if you have a premium coffee machine in your office kitchen that occasionally makes good coffees, but you notice flavour changing over time, the problem could lie elsewhere.
Coffee is a perishable product. From the moment it's roasted, it starts to lose the aromatic compounds and oils that give it flavour. Get storage right and you'll notice the difference in every cup. Get it wrong and even the best beans in the world will taste disappointing.
The Importance of Coffee Freshness
Freshly roasted coffee, stored well, gives you the best possible flavour in the cup. It extracts more consistently too, which matters if you're using an espresso machine: even small variations in bean freshness can throw off your dose, grind size, and extraction time.
Fresh beans also produce a better crema, that rich, golden layer on top of an espresso, which is one of the simplest visual signs you're serving a high-quality drink.
Stale coffee is easy to spot once you know what to look for. It tastes flat and empty, often with a papery or woody edge, and loses the brightness and complexity that make good coffee worth drinking in the first place. It's poor value for money too: you're paying for a specialty product and serving something that tastes like a much cheaper one.
The good news is that keeping coffee fresh in a workplace setting isn't complicated. It comes down to three things: buying it fresh, using it quickly, and storing it properly in between.
Buy Your Coffee From a Specialty Roaster
In order to ensure that your coffee is fresh to begin with, it's important to buy high-quality coffee from a specialty roaster that you trust.
Compared to supermarket coffee beans or instant coffee, coffee beans bought from a specialty roaster are typically roasted to order, and delivered fresh.
It's worth ordering from a roaster you trust to roast to order and turn stock over quickly, rather than a supplier selling beans that have already been sitting in a warehouse for months before they even reach you.
A quality specialty roaster will typically get coffee to you within days of roasting. That gives you the longest possible window of freshness to work with.
Order Little and Often
The single biggest factor in coffee freshness is time, specifically the time between roasting and brewing. As a general rule, coffee is best brewed within a month of its roast date. After that, it's still drinkable, but the flavour will noticeably decline.
That means the best thing you can do for your workplace coffee is order weekly or monthly rather than stockpiling months' worth in a stationery cupboard. Ordering smaller amounts more often keeps what's in the cupboard genuinely fresh, rather than letting it slowly stale before anyone gets to it.
Store Your Beans Properly
Once your coffee arrives, how you store it matters just as much as how quickly you use it. Coffee has three enemies: light, heat, and air. Get these right and you're most of the way there:
Keep it out of direct light. UV light breaks down the oils in coffee and speeds up staling, so beans should be kept somewhere dark, in a cupboard rather than on an open shelf near a window.
Keep it at room temperature. Higher temperatures speed up the chemical reactions that cause coffee to go stale, so store beans somewhere cool and stable, away from ovens, hot machinery, or radiators. Room temperature is fine; there's no need for anything more elaborate.
Keep it sealed. Exposure to air is one of the fastest ways coffee loses its flavour. In a workplace, where you're typically ordering in bulk rather than small retail bags, the simplest and most effective approach is to leave beans in their original packaging.
- Good coffee bags are designed to be airtight, and in most cases they'll protect the beans better than transferring them into a separate container, which just introduces another opportunity for air to get in. Just make sure the bag is properly resealed after each use.
Put those together and the ideal workplace setup is straightforward: a cupboard, away from sunlight and heat sources, with beans left sealed in their original bags.
What About Freezing Coffee?
You may have heard that freezing coffee extends its shelf life, and in principle that's true: freezing beans can slow staling significantly by limiting oxidation. It's a legitimate technique some home enthusiasts use when buying coffee in bulk and wanting to preserve it for months at a time.
In a workplace, though, it's rarely practical. Coffee needs to fully return to room temperature before use, or you risk condensation forming on the beans, which introduces moisture and can do more damage than it prevents.
That's hard to manage in a shared kitchen or office environment where people want a coffee on demand, not after a defrosting period. Freezer and fridge space in an office is usually at a premium too, and repeatedly opening and closing a bag to remove portions exposes the beans to temperature swings and moisture each time you do it.
If you're ordering little and often, as recommended above, freezing simply isn't necessary. The coffee will be used well within its fresh window anyway.
Your Key Takeaways
You don't need special equipment or complicated routines to keep workplace coffee tasting its best. To keep coffee fresh in the workplace, simply;
- Buy your coffee from a quality roaster who roasts to order
- Avoid stockpiling. Order weekly to ensure you have a constant supply of freshly roasted coffee
- Store it in a cupboard, away from heat and direct sunlight, and keep it sealed until you are ready to brew.
