Coffee drinkers without a machine
If you have a mug and hot water at home, work or while travelling, compare bags that steep in the mug with filters that sit on top of it. The brewing steps differ even though both make one cup.
Who might use these formats?
Shoppers looking specifically for pyramid bags
If the bag shape matters to you, check the exact product rather than relying on the words “coffee bag”. Raw Bean describes its pyramid bags as containing 12 g of coffee per bag, with a 3–4 minute steep.
People choosing a decaf evening coffee
Look for an explicitly labelled decaf variant. Raw Bean lists a decaf pyramid bag, while M&S lists individually wrapped decaffeinated coffee bags; check the label of the particular pack you choose.
What should you check before buying?
Start with how you want to brew the cup, then compare the flavour description, decaf option and disposal directions on the exact pack.
| Priority | What to check | Your needs |
|---|---|---|
| Brew format | Check whether the product is a pyramid bag, a standard coffee bag or a cup-mounted filter. Raw Bean gives a 3–4 minute steep for its pyramid bags; Rombouts instructs users to set its one-cup filter on a stable cup and pour in hot, not boiling, water to the line. | I want to make one hot cup without a coffee machine. Would I rather leave a bag to steep or pour water through a filter? |
| Flavour | Read the particular blend’s roast and tasting notes. Percol describes milk-chocolate and walnut notes for Rich Americano; tasting notes describe the brand’s intended profile, not how every cup will taste. | For a winter mug, I might prefer chocolate or nut notes to a lighter-sounding blend. |
| Caffeine | Check that the exact variant is labelled decaf if that matters to you. A roast name or flavour description does not identify a decaf product. | I would like the mug-brew routine later in the day, but want to choose the caffeine option deliberately. |
| Wrapping | Check the pack count and whether bags are individually wrapped. M&S describes its decaffeinated bags as individually wrapped; do not assume the same packaging across other products or pack sizes. | If I carry a bag to work or keep one for a trip, individual wrapping may matter more to me than it does for a pack kept at home. |
| Disposal | Read separate instructions for the used bag or filter and its wrapping. Rombouts says its used one-cup filter can be home-composted or put with food or green waste; follow the product directions and local collection rules. | I want to know where each part goes after brewing, rather than assume the bag, filter and packaging share one disposal route. |
What is easy to overlook?
-
Treating every single-serve coffee as a pyramid bag
A standard steeping bag and a filter that rests on a cup call for different brewing steps. Neither name, on its own, confirms a pyramid-shaped bag.
Check the stated format and preparation directions on the exact product before buying.
-
Using flavour descriptions to judge caffeine
Terms such as “rich” or “chocolatey” describe a flavour profile, not whether the coffee is decaffeinated.
Choose an explicitly labelled decaf variant if that is the option you want, and check its pack label.
-
Putting every part of a pack in the same bin
A claim about a used bag or filter does not necessarily cover its individual envelope or outer packaging.
Read the instructions for each component and check the collection rules where you live.
Which brands illustrate the options?
Raw Bean Coffee
A pyramid-bag option with caffeinated and decaf products in the range.
- Raw Bean describes its pyramid bags as containing 12 g of Arabica coffee each.
- The brand’s compostability and bag-shape claims should be checked against the particular bag and packaging format you buy.
Percol
A string-and-tag coffee-bag option rather than a confirmed pyramid-bag format.
- Percol lists Rich Americano as 10 bags of 8 g each, with an individually enveloped format.
- Check wrapping and disposal instructions for the particular pack rather than applying one pack’s details to the whole range.
Rombouts
Its Original One Cup Filter sits on a cup so water can pass through the coffee.
- Rombouts gives preparation directions for a stable cup and hot, not boiling, water poured to the marked line.
- This is not a steeping bag. Rombouts’ disposal advice for the used filter does not automatically cover its packaging.
Taylors of Harrogate
Tesco Groceries lists several Taylors coffee-bag variants, including Decaffe, Flying Start and Italian.
- The Tesco listings identify these as 10-bag packs.
- A coffee-bag listing alone does not establish that a variant has a pyramid construction.
M&S
Its decaffeinated coffee bags offer an individually wrapped, single-serve bag format.
- M&S describes the decaffeinated bags as made with Arabica coffee.
- Read the current pack label for the product information that matters to your choice.

Common questions
Are all coffee bags pyramid-shaped?
No. Raw Bean explicitly describes its cited bags as pyramid-shaped; Percol lists string-and-tag coffee bags, and Rombouts Original is a filter that sits on a cup. Check the exact format rather than using “coffee bag” as a shape description.
How do I prepare a Raw Bean pyramid coffee bag?
Raw Bean says to steep one of its pyramid bags in a mug of hot water for 3–4 minutes, then remove it. Follow the directions on the particular pack you buy.
How is a Rombouts one-cup filter different from a coffee bag?
Rombouts Original sits on a stable cup while hot, not boiling, water passes through the filter; its directions say to pour to the marked line. A coffee bag steeps in the mug before removal.
Does choosing decaf settle caffeine considerations in pregnancy?
No. NHS pregnancy guidance sets a limit of 200 mg of caffeine a day from all sources; choosing a decaf coffee bag does not replace checking the particular product and accounting for other food and drinks.
Can used coffee bags and filters go in food waste?
Follow the instructions for the exact product and your local collection rules. Percol directs users to the local-authority food-waste route for its bag, string and tag; Rombouts says its used one-cup filter can be home-composted or disposed of with food or green waste. Check wrapping separately.
