Choose a ready-to-drink cold brew when people need individual drinks without mixing; choose a concentrate when you can bring cups, ice and the required water or milk to serve several people. An instant-coffee jar is a different preparation route, so check the exact product description if cold brew is what you want. For any pack opened at the festival, plan around its storage instructions and check ingredients and caffeine information before serving.
A concentrate can serve several people from one pack if you have cups, ice and the mixer specified on its label. Tesco Groceries lists up to eight servings for Grind Espresso Cold Brew Coffee Concentrate, using 62 ml per serving with water or milk.
A ready-to-drink pack avoids mixing at the event. Coffee Friend UK lists a 200 ml Sandows ready-to-drink cold brew; Marks & Spencer also lists individual latte-style cold-coffee drinks.
The format alone does not establish dietary suitability or caffeine content. Marks & Spencer says its Oat Latte Cold Brew Coffee is unsuitable for coeliacs or people with a wheat allergy, while Tesco Groceries lists caffeine warnings for Solo ready to go Espresso.
Start with how the coffee will be served, then check the exact pack for portions, ingredients, caffeine and storage instructions.
| Priority | What to check | When it matters |
|---|---|---|
| Preparation | Check whether the drink is ready to consume or must be mixed. For a concentrate, check the serving measure and required water or milk. | I will not have a coffee station, so I need a drink that requires no mixing. |
| Servings | Check the pack’s stated serving count and measure rather than treating its volume as a drink count. Tesco Groceries lists 62 ml per serving and up to eight servings for Grind concentrate. | If I am making drinks for a group, I need to know how many cups one pack is intended to make. |
| Ingredients | Read the exact ingredient and allergen declaration. Marks & Spencer lists semi-skimmed milk in its Classic Latte and says its Oat Latte is unsuitable for coeliacs or people with a wheat allergy. | I need to identify a suitable option for each guest before putting coffee out to serve. |
| Caffeine | Check caffeine per stated measure, the intended dilution and any pack warnings. Tesco Groceries lists Solo at 159 mg per 100 ml and carries warnings for particular groups. | When serving concentrate, I want to measure it as directed rather than pour it like a ready-to-drink coffee. |
| Opened-pack storage | Check whether the opened pack needs refrigeration and when it must be used. Plan how to keep it chilled at the event if the label requires it. | I may have some left after serving, so I need a way to follow the pack’s storage instructions. |
The names do not establish the same preparation method or serving format. Sainsbury’s Groceries separates instant coffee and iced coffee in its categories, while Waitrose & Partners lists a liquid iced-coffee concentrate made with soluble coffee.
Decide whether you want ready-to-drink cold brew, a concentrate to mix or instant coffee, then check the exact product description.
A multi-serve pack may still contain coffee after the first round of drinks, and opened-pack instructions differ by product.
Read the pack’s refrigeration and use-by-opening instructions before taking it to a festival, and arrange chilled storage if required.
Marks & Spencer lists semi-skimmed milk in its Classic Latte; its Oat Latte is labelled unsuitable for coeliacs or people with a wheat allergy.
Keep the exact pack’s ingredient and allergen information available when serving, and check a separate option for anyone whose requirements differ.
Concentrates have product-specific measures and caffeine information. Tesco Groceries lists Solo at 159 mg caffeine per 100 ml and includes warnings for children, pregnant or nursing women, and people sensitive to caffeine.
Follow the serving and dilution instructions on the pack and check its caffeine warning before offering drinks.

For coffee prepared on site without a kettle, stir a portion into cold water and serve in a cup. The title specifies 24 portions of 2 g each; check the pack presentation if you specifically need jars, and read its caffeine information before serving.
No: an instant-coffee jar should not be treated as cold brew solely because its contents can be prepared cold. Sainsbury’s Groceries separates instant coffee from iced coffee in its categories; check the exact jar description if the brewing method matters to you.
A ready-to-drink pack needs no mixing, making it the straightforward choice when you have no serving equipment. A concentrate needs its stated measure, a mixer and a cup; Tesco Groceries directs shoppers to mix Grind concentrate with water or milk.
Follow the exact pack’s instructions for refrigeration and use after opening. Check those instructions before choosing a multi-serve pack if you expect leftovers or cannot keep an opened pack chilled as directed.
