How to Make Genuinely Good Coffee in a Hotel Room

Hotel coffee is bad for boring, fixable reasons. The machine is usually fine. The coffee is stale, the water is under-heated, the dose is wrong, and the cup is too big for what went into it. You can fix most of that with things that weigh less than a paperback.

Start with what is actually in the room

Before you pack anything, find out what you are dealing with. A pod machine, a drip brewer and a bare kettle each call for a completely different response, and "there is a coffee maker" tells you almost nothing.

That is the entire reason RoomBrew exists. Look up your hotel first — if we have researched it, the page tells you the machine, the format it takes, and how recently anyone checked.

The single highest-return change: bring your own coffee

Whatever the machine, the coffee that came with the room is the weakest link. Hotel pods and packets sit in a housekeeping cart for months, and coffee goes flat within weeks of roasting.

• Pod brewer: bring four pods of something you like. They pack flat and survive being crushed.
• Drip brewer: bring pre-ground coffee in a resealable bag, roughly 10g per cup, plus a spare filter.
• Kettle only: bring whichever brewer below suits you, or coffee bags if you want to carry nothing.

Grind before you leave if you do not want to travel with a grinder. Pre-ground coffee two days old beats fresh-ground coffee you never made because the grinder was too heavy to pack.

Fix the water

Two things go wrong with hotel water, and both are worth thirty seconds.

It is not hot enough. Pod machines and cheap drip brewers often deliver water well below the 92–96°C that gets the sweetness out of coffee. If you have a kettle, boil it and let it stand for about thirty seconds. If you only have a pod machine, run one cycle with no pod first — it warms the machine and gives you a hotter cup.

It tastes of the machine. Any brewer that has sat unused holds stale water in its lines. Run a full cycle of plain water and discard it before you brew anything you intend to drink. This costs you two minutes and fixes more than any other single step.

Get the ratio right

The most common hotel coffee mistake is using one pod or one packet to fill an enormous mug. The dose is calibrated for a small cup.

A reliable starting point is 60g of coffee per litre of water — about 15g of coffee for a 250ml cup. If you are using a pod designed for a 150ml espresso-style serving and pulling 300ml through it, you are drinking hot brown water and blaming the hotel.

If your cup tastes weak, use less water rather than more coffee. Pulling extra water through a spent pod extracts bitterness, not strength.

What to actually pack

In rough order of how much they improve things per gram carried:

1. Your own coffee — pods, grounds, or bags to match the machine.
2. An AeroPress Go — makes genuinely excellent coffee, packs into its own mug, needs only hot water. See using an AeroPress in a hotel room.
3. A collapsible pour-over cone and filters — lighter still, and nearly as good. See pour-over in a hotel room.
4. Specialty instant — genuinely good now, weighs nothing, needs only hot water.
5. A small scale — only if you are the sort of person who already owns one.

Clean the machine before you use it

In-room brewers are cleaned far less often than you would hope, and pod machines in particular hold standing water. A vinegar cycle is not realistic on the road, but a plain hot-water cycle through an empty machine flushes most of what you would otherwise taste.

For a drip brewer, wash the carafe in the bathroom sink with hot water first. It is usually the dirtiest part.

When the room has nothing

If there is no machine and no kettle, you are not stuck. Room service and the lobby will both give you hot water, usually free, and that is all most travel brewers need. See how to get hot water in a hotel and what to do when your hotel has no coffee maker.
