What should you check before buying?
Choose when you will drink the coffee first, then check what you can carry and what you will need to prepare it.
Ready-to-drink cold brew
Choose it when: You want a cold drink without mixing and plan to buy it after security or drink it before screening.
Trade-off: A larger container may not pass through security in hand luggage, and latte-style drinks can contain milk and sugar.
Cold-brew concentrate
Choose it when: You will make several drinks at your destination and have what you need to dilute it.
Trade-off: It is not ready to drink, and opened packs may need refrigeration and use within a product-specific period.
Dry instant coffee
Choose it when: You would rather carry dry coffee and can obtain water and a cup after screening or at your destination.
Trade-off: It is not cold brew; a cold drink needs suitable preparation, and food powders can receive additional screening.

What to check |
Your needs |
| Airport security |
Check container capacity and the rules at each relevant airport. GOV.UK says containers larger than 100ml cannot pass through security at most UK airports; powders may also lead to a bag check. |
I want to take coffee on the journey without relying on a larger drink container being allowed through security. |
| Preparation |
Check whether it is ready to drink, needs dilution or is soluble coffee. Confirm the water, cup and cold-drink directions you will need. |
Will I have time and somewhere to make a drink, or do I want to open one after screening? |
| Ingredients |
Read the current ingredients and allergen label. The Marks & Spencer latte example contains semi-skimmed milk and sugar; product recipes can differ. |
If I am avoiding milk or want coffee without added sugar, I need to check the particular pack rather than assume all cold brew is black coffee. |
| Pack use |
Check the number of portions and instructions after opening. Tesco says its Finest concentrate needs refrigeration and use within four weeks; Grind states seven days for its concentrate. |
A single drink at the gate calls for a different pack from several drinks made during a stay. |

Frequently asked questions
Can I take bottled cold brew through UK airport security?
Check the airports on your journey before packing it. GOV.UK says most UK airports do not allow liquids in containers larger than 100ml through security, so do not assume a larger bottle or can will pass even if partly full. Buying a drink after security avoids taking that drink through screening.
Is an instant-coffee jar a substitute for bottled cold brew?
It is an alternative for making coffee later, but instant coffee is not cold brew or a ready-made drink. Check how to prepare a cold serving and whether you will have water, a cup and any required ice or milk. GOV.UK notes that food and powders can lead to additional bag checks.
Can I save a cold brew bought before security for the flight?
Only plan to take it through screening if its container meets the rules at your departure airport. The Marks & Spencer ready-to-drink latte example is 250ml, above the 100ml container limit that GOV.UK says applies at most UK airports. Otherwise, drink it before security, buy one afterwards or use hold luggage where appropriate.
How long can I keep opened cold-brew concentrate?
Follow the instructions for the particular product. Tesco says to refrigerate its Finest concentrate after opening and use it within four weeks; its Grind listing specifies refrigeration and consumption within seven days for that concentrate.
How do I check whether a cold coffee contains milk or sugar?
Read the current ingredients and allergen information on the pack. The Marks & Spencer latte example contains semi-skimmed milk and sugar, while Tesco describes its Finest concentrate as unsweetened and suitable for vegans. Those details should not be assumed for other cold coffees.
