Hosts serving coffee quickly
Choose an instant coffee you can portion consistently with hot water. Make a test cup before the sale, especially if you expect to serve it black.
Who is this for?
Hosts expecting a steady queue
Plan quantities around the serving size on the pack, not its weight alone. Sainsbury's lists approximately 111 mugs for NESCAFÉ Gold Blend Intense 190 g and 50 mugs for AZERA Americano Intense 90 g.
Sellers offering refreshments
If you are operating a food business rather than sharing drinks privately, establish the applicable registration and food-information requirements before trading. The Food Standards Agency provides the food-business registration guidance.
What should you check?
Start with the flavour you want to serve, then work out a repeatable portion and how many packs that portion will require.
| Priority | What to check | Your needs |
|---|---|---|
| Bold flavour | Read the roast and flavour description. Kenco rates Rich at intensity 9, but NESCAFÉ's strength guide says intensity numbers describe flavour rather than caffeine content; do not compare different brands' scales as caffeine measures. | I want a pronounced flavour, particularly if visitors may drink the coffee black. |
| Repeatable portions | Check the coffee measure and water volume on the chosen pack. Sainsbury's gives one teaspoon, or 1.8 g, with 200 ml hot water for a mug of Gold Blend Intense. | Each cup should taste consistent even when several people take turns serving. |
| Enough servings | Use the stated yield at its specified serving size. Sainsbury's lists approximately 111 mugs from Gold Blend Intense 190 g and 50 mugs from AZERA Americano Intense 90 g; changing the portion changes the number you can make. | I need enough of the same coffee to serve the expected cups, with some allowance if more visitors stop by. |
| Product availability | Confirm stock before depending on a particular jar. Sainsbury's Carte Noire Intense 100 g listing showed it out of stock, so check availability when you shop. | A coffee I cannot obtain in time will not work as my only event-day option. |
| Selling refreshments | Establish whether your activity is a food business. The Food Standards Agency says a new food business must register with its local authority at least 28 days before trading; prepacked-for-direct-sale food has separate labelling requirements. | If I am selling food or drink, I need to settle the applicable requirements before the sale rather than assume the rules for private sharing apply. |
What could catch you out?

Reading “strong” as “more caffeine”
NESCAFÉ's strength guide says intensity numbers tend to describe flavour, not caffeine content. An intensity score cannot establish which coffee contains more caffeine.
Choose by roast and flavour description when bold taste is the goal; check the exact product information if caffeine matters.
-
Buying a small tin without counting cups
A pack's stated yield depends on its serving measure. Sainsbury's lists 50 mugs for AZERA Americano Intense 90 g, compared with approximately 111 for Gold Blend Intense 190 g.
Estimate the cups you expect to serve, test your portion and obtain enough of the chosen product for that portion.
Using more coffee per cup than the labelled measure means the pack will make fewer cups.
-
Depending on an unchecked listing
Sainsbury's Carte Noire Intense listing showed the product out of stock. A suitable flavour description does not establish that a jar will be available when you need it.
Confirm stock before the event and test an alternative if that particular coffee matters to your plan.
-
Trusting a product title over its ingredients
A Joybuy page titled Kenco Rich Instant Coffee 100 g lists ingredients including milk proteins. Its AZERA Americano Intense 90 g page lists decaffeinated coffee ingredients. Those details can change what you offer visitors.
Check the product details and physical pack before treating either listing as the conventional coffee suggested by its title, particularly when caffeine or milk ingredients matter.
Relevant brand references
Kenco
Kenco Rich is a conventional instant option for a bold-flavour brief.
- Kenco GB gives Rich an intensity rating of 9.

- Sainsbury's lists approximately 111 mugs from Gold Blend Intense 190 g and 50 from AZERA Americano Intense 90 g at their stated servings.

No image available
NESCAFÉ Azera Americano Intense 90 g
Check this 90 g product's identity before choosing it for visitors expecting regular coffee: the Joybuy ingredient information identifies decaffeinated soluble and roast-and-ground coffee despite the title not saying decaffeinated.

Douwe Egberts Pure Indulgence Coffee 190 g
For repeated servings from this 190 g pack, check the physical label for its coffee measure, water volume and caffeine information. Pack weight alone does not establish how many cups your chosen portion will make.
Common questions
Does a higher intensity number mean more caffeine?
No. NESCAFÉ's UK strength guide says coffee strength numbers tend to describe flavour intensity rather than caffeine content. Use the number to understand that brand's flavour description, not to rank products by caffeine.
How can I keep each cup consistent?
Start with the directions on the exact pack and test them in the cups you will serve. For NESCAFÉ Gold Blend Intense 190 g, Sainsbury's lists one teaspoon, or 1.8 g, with 200 ml hot water as one mug; use the same measure and water volume for subsequent cups.
Do I need to register to sell coffee at a car boot sale?
If you are starting a food business, the Food Standards Agency says you must register with your local authority at least 28 days before trading. Whether your particular activity is a food business depends on what you do, so check with the relevant local authority rather than treating a sale as private sharing.
What labelling applies if I pack food to sell at the stall?
For food that falls within prepacked-for-direct-sale requirements, the Food Standards Agency and Food Standards Scotland state that, since 1 October 2021, its label must show the food's name and a full ingredients list with the 14 regulated allergens emphasised. Establish whether each item you pack falls within that category; the rule does not automatically describe an opened jar used to make drinks.
