For quick handover at a car boot sale, individually packaged, ready-to-drink cold brew involves less preparation at the stall than concentrate. Concentrate is an option if you can measure and mix each drink, but first establish whether ‘240’ means sealed units or prepared servings, then confirm the exact product’s pack quantity and directions. A larger bag-in-box format needs its own supply and serving checks.
Who is each format for?
Sellers handing over sealed drinks
A ready-to-drink can keeps preparation away from the stall and lets customers see its original label. Marks & Spencer lists its Classic Latte Cold Brew Coffee as a 250ml ready-to-drink product; check the quantity available to order rather than treating a single can as evidence of a catering case.
Sellers mixing drinks to order
Concentrate suits a stall set up to measure, dilute and serve each drink. Tesco lists a 500ml cold-brew concentrate, but the serving plan must follow that exact product’s directions, including its storage and ingredient information.
Sellers considering a dispenser
A bag-in-box puts the drink in a larger container with a tap rather than individual cans. Amazon UK’s listing describes a Sandows 3L format but marks it unavailable, so confirm a supplier and the product’s handling instructions before planning around it.
What should you check before ordering?
Define the number of packaged drinks or prepared servings you intend to offer, then choose a service format you can manage at the stall.
| Priority |
What to check |
Your needs |
| Order quantity |
Specify whether 240 means sealed drinks, coffee bags or servings after dilution. Confirm the supplier’s case contents and use only the chosen concentrate’s own directions to calculate servings. |
I need a count I can order against, rather than assuming a box size or treating concentrate volume as a serving count. |
| Service method |
Marks & Spencer lists a ready-to-drink 250ml Classic Latte; Tesco lists a 500ml cold-brew concentrate. Check whether you can provide the water, measuring and serving equipment needed for a drink mixed at the stall. |
If customers are collecting a sealed drink, I want to hand it over without mixing. If I am preparing drinks, I need a workable serving setup. |
| Ingredients and labels |
Read the exact product’s ingredients and allergen information. Marks & Spencer describes semi-skimmed milk in its Classic Latte; keep the current product information accessible when serving. |
Customers should be able to check what is in the drink, particularly when the option I stock contains milk. |
| Storage and dispensing |
Check the chosen product’s storage directions, including any instructions for after opening. For a dispenser, establish how it will be carried, set up and served. |
I need a format I can transport and serve in line with its own instructions throughout the event. |
| Trading arrangements |
Check the organiser’s requirements and ask the relevant local authority whether your activity needs food-business registration. Include any drink preparation in your food-safety arrangements. |
Before selling, I want to know which requirements apply to my stall and how I will manage the drinks I serve. |
Ordering mistakes to avoid
-
Assuming ‘240’ describes a standard cold-brew case
Marks & Spencer’s 250ml can, Tesco’s 500ml concentrate and the Sandows 3L bag-in-box are different ways of supplying drinks. None of those pack descriptions establishes a 240-unit case or a 240-serving yield.
Tell the supplier whether you mean individual sealed drinks, coffee bags or finished servings, and ask for the actual case contents before ordering.
-
Applying one brand’s concentrate recipe to another
MONIN UK gives a recipe using 25ml of its own concentrate. That does not establish the dilution ratio or serving yield of Tesco Finest Unsweetened Cold Brew Coffee Concentrate.
Use the directions for the exact concentrate you buy before calculating how many drinks it will make.
-
Separating a milk-based drink from its ingredient information
Marks & Spencer’s Classic Latte contains semi-skimmed milk. Food Standards Agency and GOV.UK event guidance sets out name, ingredient and emphasised-allergen information requirements for prepacked and prepacked-for-direct-sale foods.
Keep the current packaging or legible product information available so customers can check the drink you are offering.
-
Assuming a temporary stall has no food-business duties
Food Standards Agency and GOV.UK guidance for England, Wales and Northern Ireland says selling or handling food can make an operator a food business; the nature and frequency of an event matter to the local assessment. Food Standards Scotland says food businesses in Scotland must register with their local authority.
Ask the event organiser and the relevant local authority before trading. Where registration applies, the cited official guidance calls for it at least 28 days before starting.
Brand and retailer references
M&S
Marks & Spencer lists Classic Latte Cold Brew Coffee as a 250ml ready-to-drink product.
- The product page says to store it in a cool, dry place.
- This latte contains semi-skimmed milk; confirm its current label and the quantity available to order.
Tesco
Tesco Groceries lists Finest Unsweetened Cold Brew Coffee Concentrate 500ml and Finest Brown Sugar Cold Brew Latte 250ml.
- The listings offer a choice between concentrate for preparation and a latte in a single-serve size.
- For the concentrate, check its own dilution, ingredients and storage directions before planning servings.
Sandows
Amazon UK describes Sandows Original Cold Brew Coffee in a 3L bag-in-box with a tap.
- A dispensing tap offers a different service arrangement from handing over individual cans.
- That Amazon UK listing was marked unavailable; confirm supply and handling instructions before relying on this format.
Waitrose
Waitrose & Partners lists coffee bags in its coffee sachets category, including 10-count and 15-count packs.
- These listings give concrete pack counts to compare if ‘240’ refers to coffee bags.
- Check the individual product: the listed coffee bags are not identified as a 240-count cold-brew pack.
Sainsbury's
Sainsbury’s coffee category includes an iced-coffee subcategory.
- The category provides a place to check individual iced-coffee products.
- Confirm a specific product’s cold-brew description and pack quantity rather than relying on the category name.
Joybuy products for stall preparation
This Joybuy option is a portioned cold-brew coffee liquid to mix at the stall, not a sealed ready-to-drink can. Its stated pack of 10 pouches does not itself meet a request for 240 individually packaged units or establish a 240-serving case.

J.ZAO Extra-Strong Americano Cold Brew Coffee Liquid, 25ml × 10 pouches
The individually portioned liquid suits a stall where drinks can be mixed to order rather than handed over ready to drink. The pack is labelled as 10 pouches of 25ml each; check the product’s mixing and ingredient instructions and confirm the order quantity needed for your event.

Questions about buying and serving
Does ‘box of 240’ identify a cold-brew catering pack?
Not by itself: 240 could describe sealed drinks, coffee bags or servings made after dilution. Specify the unit you need and ask the supplier to confirm the product’s case contents or stated serving instructions before ordering.
Do I need to register to sell cold brew at a car boot sale?
Registration depends on whether your activity is treated as a food business. Food Standards Agency and GOV.UK guidance says selling or handling food can make an operator a food business in England, Wales and Northern Ireland; Food Standards Scotland says food businesses in Scotland must register. Ask the relevant local authority about your activity and location before trading; where registration applies, the cited guidance calls for it at least 28 days before starting.
What ingredient information should customers be able to check?
Keep the exact drink’s current packaging or legible product information available. Food Standards Agency and GOV.UK event guidance requires the food name and a full ingredients list with mandated allergens emphasised for prepacked and prepacked-for-direct-sale foods; this matters for Marks & Spencer’s Classic Latte, which contains semi-skimmed milk.
Is a black cold brew automatically a milk-free alternative to a latte?
Do not rely on the drink name alone: check the exact product’s ingredient and allergen label. Marks & Spencer describes semi-skimmed milk in its Classic Latte; a different product needs its own label check before you describe it to customers avoiding milk.
Can I calculate servings from any 500ml concentrate?
No. Use the chosen product’s own dilution instructions to calculate yield. MONIN UK’s recipe is for its concentrate and cannot establish how many drinks Tesco’s 500ml cold-brew concentrate will make.
