Self-catering festival campers
If you are packing drinks for several campsite meals, decide whether you can carry water, cups and a way to refrigerate an opened concentrate. A ready-to-drink bottle removes the mixing step.
Who is this for?
Campers checking ingredients and allergens
Black coffee, dairy latte and oat latte are different choices. Marks & Spencer lists semi-skimmed milk in its Classic Latte and labels its Oat Latte unsuitable for coeliacs or people with a wheat allergy.
Campers keeping track of caffeine
Check the declared amount and serving size rather than treating every cold brew as equivalent. Coffee may be only one of several sources of caffeine during a festival day.
What matters when choosing?
Start with what you can prepare and store at camp, then decide whether an unsweetened black coffee or a latte suits the food and additions you are bringing.
| Priority | What to check | Your needs |
|---|---|---|
| Preparation | Check whether the drink needs diluting and what you must bring. Tesco Groceries instructs shoppers to mix 100 ml of Tesco Finest concentrate with 100 ml of cold water; its Grind listing gives 62 ml of concentrate per serving, mixed with water or milk. Ready-to-drink black coffee needs no dilution. | I can bring water and a cup if I want to adjust a concentrate. Otherwise, I would rather open a drink that is ready to go. |
| Flavour and food | Compare unsweetened black coffee with drinks containing milk, oats or sugar. Check the particular blend or roast description if its flavour matters to you; format alone does not establish how it will taste. | For savoury food, I may want black coffee. With breakfast food, I might prefer to add my own milk or choose a latte with those ingredients already mixed in. |
| Ingredients | Read the pack’s ingredient and allergen statements. Marks & Spencer lists semi-skimmed milk in Classic Latte and says its Oat Latte is unsuitable for coeliacs and people with a wheat allergy. | Someone in our group needs a suitable drink, so an oat-based or dairy-free description alone will not settle the choice. |
| Caffeine | Compare caffeine declarations on the same serving basis. Coffee Friend UK lists Sandows black cold brew at 40.5 mg per 100 ml; Tesco Groceries lists approximately 45 mg per 250 ml serving for Califia Farms Caramel Oat Cold Brew. | I want to know how much is in the portion I will drink, alongside any other caffeinated drinks or food I bring. |
| Storage | Check both unopened and after-opening instructions, especially if your cool box has limited space. Tesco Groceries says to refrigerate Tesco Finest concentrate after opening and consume it within four weeks; its Grind listing specifies refrigeration and seven days after opening. | If I cannot keep an opened pack refrigerated, its unopened storage instructions are not enough for my trip. |
What should you avoid?
-
Packing concentrate without a way to prepare and store it
Concentrate needs water and a cup, while the Tesco Finest and Grind products listed by Tesco Groceries both require refrigeration after opening.
Check the preparation and after-opening directions before departure. If you cannot meet them, choose a ready-to-drink format with storage instructions that work for your trip.
-
Assuming an oat latte meets every dietary requirement
Marks & Spencer says its Oat Latte is unsuitable for coeliacs and people with a wheat allergy; its Classic Latte contains semi-skimmed milk.
Read the ingredient and allergen statement on the exact pack you buy. If you plan to add milk separately to black coffee, check that addition too.
-
Treating all cold-brew portions as equal
Serving sizes and declared caffeine amounts vary. A concentrate portion and a ready-to-drink bottle cannot be compared by pack size alone.
Use the pack’s caffeine declaration and serving instructions where available, and account for caffeine from other drinks and food.
-
Planning around an unchanged listing
A product’s ingredients, allergen information or availability can change before a festival.
Check the current pack and retailer listing before buying, particularly when choosing for a dietary requirement or planning how to store the drink.
Brand and product-line references
These examples show how concentrate, black ready-to-drink coffee and lattes differ; each storage or ingredient detail applies to the product named, not every drink from that brand.

Frequently asked questions
Which cold-brew format takes the least preparation at a campsite?
Ready-to-drink coffee needs no mixing, making it the simpler format when water and cups are limited. Concentrate lets you adjust a drink if you can bring what it needs: Tesco Groceries specifies 100 ml concentrate and 100 ml cold water for Tesco Finest, while its Grind listing gives a 62 ml concentrate serving mixed with water or milk.
Should I take black cold brew or a latte with camping food?
Take unsweetened black cold brew if you want to decide at camp whether to add milk or keep the coffee black. A ready-mixed latte is the more straightforward choice if you want those ingredients already included: Marks & Spencer lists semi-skimmed milk and sugar in its Classic Latte, and oats in its Oat Latte. Check the particular drink’s flavour description rather than assuming every cold-brew blend tastes alike.
Can I leave an opened cold-brew concentrate in my tent?
Not if its label requires refrigeration after opening. Tesco Groceries gives that instruction for both Tesco Finest and Grind concentrates, with consumption periods of four weeks and seven days respectively. Plan for suitable chilled storage or choose another format whose directions you can follow.
How do I compare caffeine in cold-brew drinks?
Compare declared caffeine amounts alongside their serving sizes, and include other sources of caffeine during the day. Coffee Friend UK lists Sandows at 40.5 mg per 100 ml, while Tesco Groceries lists approximately 45 mg per 250 ml serving for Califia Farms Caramel Oat Cold Brew. Those figures describe different products and portion sizes, not a standard amount for cold brew.
Is an oat cold-brew latte suitable for coeliacs?
Do not assume so from the word “oat”. Marks & Spencer labels its Oat Latte Cold Brew Coffee unsuitable for coeliacs and people with a wheat allergy. Read the allergen statement on the specific drink you buy.
