Are coffee bags as good as ground coffee?

Yes, with a small caveat. The coffee inside is the same quality. The only difference is that you cannot control grind size or brew ratio as precisely as you would with a cafetiere or pour-over. For day-to-day drinking, the difference is negligible.

How much caffeine is in a coffee bag?

It depends on the bean. A standard Arabica coffee bag delivers roughly 80 to 110mg of caffeine per cup. Contact Coffee Red On bags use 100% Robusta and hit 1,293mg per 12fl oz brewed, the strongest coffee bag available in the UK.

Can you reuse a coffee bag?

Once, for a weaker top-up. The first brew pulls about 70% of the strength. The second brew gives you a lighter cup, which some people prefer mid-morning. Beyond that, the bag is spent.

How long do you steep a coffee bag?

Two to four minutes. Two for a medium cup, four for stronger. Beyond four minutes, you start to extract bitter compounds without adding much more strength.

Coffee bags vs instant coffee, what is the difference?

Instant coffee is dehydrated brewed coffee, ground into crystals or powder. Coffee bags contain actual ground coffee that you brew at the point of drinking. The flavour difference is significant: instant is fast and weak with a characteristic processed taste, coffee bags taste like real coffee because they are real coffee.

Can you make iced coffee with coffee bags?

Yes. Brew at double strength (125ml hot water for 2 to 3 minutes), then pour over a glass of ice. You can also cold-brew by leaving a bag in 250ml cold water in the fridge for 8 to 12 hours.

How long do coffee bags last unopened?

Sealed coffee bags stay fresh for 6 to 12 months. Once you open the outer pack, drop the bags into an airtight container and use within 3 to 4 weeks for best flavour. Contact Coffee single-serve bags are individually sealed so they hold freshness longer.

What is the strongest coffee bag UK?

Contact Coffee Red On High Caffeine Coffee Bags. 100% Robusta from the Badra Estate, single-origin, delivering 1,293mg of caffeine per 12fl oz brewed. We have not seen a stronger coffee bag on sale in the UK.

Can you use a coffee bag in a flask?

Yes. Add the bag and boiling water to a thermos flask, seal, and leave for 4 to 5 minutes. Remove the bag with a long teaspoon. The coffee stays hot for hours. Useful for early starts when you need a hot brew at 0500 without faffing with a kettle later.

Direct from Contact Coffee. The 100-pack and 300-pack options give the best price per cup, and we offer trade pricing for military units, workplaces, and emergency services. Email hello@contactcoffee.com for bulk and trade enquiries.

Coffee Brew Bags

all coffee | coffee beans | ground coffee | nespresso pods

Real ground coffee in a tea-bag format. Drop one in a mug, pour over hot water, wait two to four minutes. No machine, no mess. British-roasted, military-grade strong.

Coffee brew bags built for strength

Coffee bags work exactly like a tea bag, except the bag is filled with proper ground coffee instead of tea. Drop one in your mug, add boiling water, steep for two to four minutes, squeeze and remove. You get a genuine cup of freshly brewed coffee with no machine, no grinder, no cafetiere and no cleanup. These are not instant coffee. Every bag in this collection contains the same UK-roasted coffee we sell as beans and ground, portioned into a biodegradable filter and individually wrapped to seal in freshness.

We built our coffee brew bags for people who need strong coffee in places where brewing kit does not exist: early shifts, wild camps, hotel rooms, offshore rotations and deployments. If you want the best coffee bags UK roasters can offer without paying supermarket prices for supermarket strength, this is the range.

Choose your blend

Red On is our strongest option: a single origin 100% Robusta from the Badra Estate in South West India, delivering 1,293mg of caffeine per 12fl oz brewed. It scores 5 out of 5 on our coffee strength scale and is the strongest coffee bag we have seen on sale in the UK. Start with the Red On 10-pack if you want to test it before committing.

Battle Prep is the daily driver: a full-bodied blend of coffees from Brazil and Latin America with powerful notes of liquorice and cocoa. Strong enough to wake you up, smooth enough to drink three times a day.

Both blends come in 10-bag boxes at £6.99 for first-timers, a 60-bag mixed bundle at £37.99, and 100-bag resupply boxes at £52.99 for the best price per cup.

Why these beat supermarket coffee bags

Supermarket coffee bags are roasted months before they reach the shelf and packed loose, so the coffee is stale before you brew it. Ours are roasted in the UK, packed fresh, and each 8g bag is individually sealed, so the last bag in the box tastes like the first. The filter material is biodegradable, so a used bag goes in the food waste, not landfill. And every order supports a veteran-owned British business rather than a multinational.

How to brew one

Put the bag in your mug, pour over 250ml of freshly boiled water, and steep for two minutes for a medium cup or four for a strong one. Give it a stir, squeeze the bag against the side of the mug, and bin it. One bag makes one strong mug. In a flask, seal the bag in with the water for four to five minutes and the coffee stays hot for hours.

Real coffee for camping, work and deployment

A box of brew bags weighs next to nothing and needs only hot water, which is why they have become standard kit for hikers, military personnel, emergency services and anyone stuck with bad office coffee. If you brew outdoors, our guide to camping with coffee covers the setups that work in the field. For everything you need to know about caffeine content and what strong actually means, start with the coffee strength scale guide.

Why Choose Coffee Bags

Coffee bags solve a simple problem: how to brew real coffee when you have no machine, no grinder, and no time. Each bag holds speciality ground coffee, freshly roasted and packed in the UK, sealed to lock in flavour. Drop a bag in a mug, add hot water, and in a few minutes you have a strong, smooth brew with no mess and nothing to clean.

These are not instant coffee. They are not flavoured, weak, or gimmicky. They are made for people who still want a proper cup, just without the grinding, measuring, and washing up. Ideal for early shifts, hotel rooms, campsites, kit bags, the office, or a faster brew at home.

Coffee Bags FAQ

How do coffee bags work?

Coffee bags work like tea bags. Each bag holds real ground coffee. Place a bag in your mug, pour over hot water, leave it to brew for two to four minutes, give it a stir, then remove the bag. There is no machine, filter, or grinding involved.

Are coffee bags as good as fresh ground coffee?

Coffee bags use the same freshly roasted, speciality ground coffee you would brew any other way, so the cup quality is far closer to fresh ground than to instant. They are not instant coffee. The trade is a small amount of convenience for the ability to brew real coffee anywhere with just hot water.

How many cups can you get from one coffee bag?

One coffee bag makes one strong mug of coffee. For a larger mug or a slightly weaker cup, many drinkers get a second, lighter brew from the same bag by topping up with more hot water.

Are Contact Coffee coffee bags biodegradable?

Yes. Contact Coffee brew bags are made with biodegradable bag material, so a used bag can go in your food or garden waste rather than landfill.

Are coffee bags good for camping and travel?

Coffee bags are ideal for camping, travel, hotels, and work. Each bag is lightweight, individually sealed for freshness, and needs only hot water, so there is no machine, grinder, or mess to carry or clean.
