Nearly every office has someone who says they’ll just have water. Often it’s not that they don’t like coffee; it’s that they can’t or shouldn’t have any more.
Maybe it’s their third cup of the day. Maybe it’s 3 pm, and they want to get a good night’s sleep tonight. Or maybe they’re pregnant, sensitive to caffeine, or simply trying to cut back.
Whatever the reason, those colleagues deserve a proper cup of coffee too. A good decaf means everyone can join in with coffee breaks, not just the people who can handle another espresso.
In this guide, we look at why decaf coffee for the office matters more than many businesses realise, who in your team is likely to want it, and how to offer a decaf coffee that people genuinely enjoy drinking.
Why does decaf coffee matter at work?
Decaf matters because a large share of your team already drinks it. It is estimated that around 1 in 5 UK coffee drinkers regularly drink decaf, and that number has been growing for years.
Interest in cutting back is growing too. Trade publication Perfect Daily Grind reports that a 2024 Euromonitor survey found interest in drinking less caffeine, or none at all, had reached a record 46%.
In other words, decaf is no longer a niche request. If your office coffee machine only offers full-strength coffee, you could be leaving a significant part of your team with nothing they want to drink.
Who in your team needs decaf coffee?
Most offices have more decaf drinkers than they realise, which is why decaf coffee for the office is worth getting right. They usually fall into a few groups:
- Afternoon coffee drinkers. Caffeine stays in the body for hours. A 2023 review of 24 studies in Sleep Medicine Reviews found that your last cup of coffee should be drunk at least 8.8 hours before bed to avoid losing sleep. With a 10 pm bedtime, that means switching to decaf from around 1 pm.
- Pregnant colleagues. The NHS advises that pregnant women should not have more than 200mg of caffeine a day, including from tea, cola and chocolate. A good decaf lets them keep enjoying their coffee break without adding much to that total.
- People who are sensitive to caffeine. Some people feel jittery, anxious or unsettled after even one strong coffee. Decaf gives them the taste and the ritual without the side effects.
- Anyone cutting back. Plenty of people want to reduce their caffeine for health or wellbeing reasons, but still enjoy a warm drink at their desk.
- Heavy coffee drinkers. Those who get through several cups on a busy, meeting-packed day can switch to decaf later on without giving up their coffee habit.
Offering decaf isn’t about telling anyone what to drink. It’s about giving everyone a choice.
Is decaf coffee actually caffeine-free?
No, decaf coffee is not completely caffeine-free, but it contains very little. Under UK regulations, instant coffee can only be labelled decaffeinated if caffeine makes up no more than 0.3% of its dry coffee content. Water-processed decaf beans go further, with around 99.9% of the caffeine removed.
In the cup, that works out at roughly 2 to 15mg of caffeine for a standard decaf, compared with around 95 to 135mg for a regular filter coffee, according to Swiss Water. That’s a small fraction of a normal cup.
What is the Mountain Water Process?
The Mountain Water Process is a natural way of removing caffeine from coffee using water instead of chemical solvents. It uses pure water from Pico de Orizaba, Mexico’s highest mountain.
Here’s how it works, in simple terms:
- Green (unroasted) coffee beans are soaked in mountain water, which draws out the caffeine along with the flavour compounds.
- The water is filtered to remove only the caffeine, leaving a liquid full of coffee flavour.
- Fresh beans are then soaked in this flavour-rich water. Because it already holds the flavour compounds, it removes the caffeine but leaves most of the flavour in the beans.
- The beans are dried, ready to be roasted.
The result is coffee that is around 99.9% caffeine-free, with no chemical residue. It’s the method we use for our Puro Decaf Coffee.
Does decaf coffee taste worse than regular coffee?
Good decaf coffee doesn’t have to taste worse than regular coffee. In fact, its poor reputation largely comes from older, harsher decaffeination methods and from decaf beans that have sat on the shelf for too long because hardly anyone used them.
Today, a freshly roasted, water-processed decaf can hold its own against a regular blend. Our Puro Decaf coffee, for example, keeps its bold caramel, toffee and nut flavours, so it works just as well in a latte as it does in an espresso.
If your team has tried decaf before and didn’t like it, it may simply be that they haven’t tried a good one yet.
How to offer decaf coffee in your office
The easiest way to offer decaf is to make it as simple to choose as any other drink. There are a few ways to do this:
- Choose a machine with two bean hoppers. Machines such as our Boss and Chief have dual bean hoppers, so you can keep decaf beans in one and your regular blend in the other. Your team simply picks decaf on the menu.
- Keep a decaf option next to the machine. If you have a single-hopper machine, a quality decaf instant or decaf espresso gives people a reliable alternative.
- Label it clearly. Make sure decaf is easy to find on the drinks menu or coffee station, so no one has to ask.
- Keep it fresh. Store decaf beans in an airtight container away from light and heat, just like your regular coffee. Our guide on how to store coffee beans explains more.
- Ask your team. A quick poll or a coffee tasting will show how many people want decaf and which one they enjoy most.

Frequently asked questions
Why should an office offer decaf coffee?
Offices should offer decaf because around 1 in 5 UK coffee drinkers regularly choose it. A good decaf lets afternoon drinkers, pregnant colleagues, caffeine-sensitive staff and anyone cutting back still enjoy their coffee break.
How much caffeine is in decaf coffee?
A standard cup of decaf usually contains around 2 to 15mg of caffeine. A regular filter coffee contains around 95 to 135mg, so decaf has only a small fraction of the caffeine.
Is decaf coffee safe during pregnancy?
The NHS advises pregnant women to have no more than 200mg of caffeine a day. Decaf contains only a few milligrams per cup, so it is a popular way to enjoy coffee while staying well under that limit. Anyone with concerns should speak to their midwife or GP.
What time should you stop drinking caffeinated coffee?
A 2023 review of 24 studies in Sleep Medicine Reviews found that your last cup of coffee should be drunk at least 8.8 hours before bed to avoid reducing sleep. For a 10 pm bedtime, that means around 1 pm, which is why many people switch to decaf after lunch. Everyone is different, though. Some people are happy to stop at 5 or 6 pm, so it’s worth knowing how your own body handles caffeine.
What is Mountain Water Process decaf?
Mountain Water Process decaf is coffee that has had its caffeine removed using pure water from Pico de Orizaba in Mexico, rather than chemical solvents. The process keeps most of the coffee’s natural flavour and leaves the beans around 99.9% caffeine-free.
Can you have decaf in a bean-to-cup coffee machine?
Yes. Bean-to-cup machines with two bean hoppers, such as our Boss and Chief, can hold decaf beans alongside a regular blend, so employees can choose decaf straight from the drinks menu.
