Guests who want a bolder coffee taste
If you want a portable cold coffee for Bonfire Night, compare the described flavour and the drink format. A strong-tasting coffee is not necessarily one with a higher stated caffeine amount.
Who is this choice for?
Shoppers avoiding dairy
An oat latte and a black cold brew offer different ways to avoid milk. M&S describes its Oat Latte Cold Brew as dairy-free, but says it is unsuitable for people with coeliac disease or a wheat allergy; Coffee Friend UK lists Sandows as a dairy-free black coffee.
Guests checking sugar or caffeine
Compare the nutrition information on the same basis and consider the amount in the whole drink. If caffeine intake matters, check the amount per serving and account for other sources consumed that day.
What should you check?
Choose the drink format first, then check flavour, ingredients, serving information and what you will need to serve it at the gathering.
| Priority | What to check | Your needs |
|---|---|---|
| Coffee strength | Read flavour descriptions separately from any stated caffeine amount per serving. Waitrose explains coffee strength in terms of flavour intensity; a brand's “strong” description is not a caffeine measurement. | I want a more pronounced coffee taste, but I do not want to mistake that description for a caffeine figure. |
| Milk and allergens | Check whether the drink contains milk or oats, and read the current allergen statement. M&S says its Oat Latte Cold Brew is unsuitable for people with coeliac disease or a wheat allergy. | A black coffee or a dairy-free latte could work for me, provided its ingredients and allergen information fit my requirements. |
| Sugars | Compare nutrition figures using the same stated basis, such as per 100ml, before looking at the amount in a whole can or bottle. Do not treat a per 100g figure as a per 100ml figure. | I want to know what is in the full drink, not judge it by the size of the container alone. |
| Caffeine | Look for a figure per serving and check the serving size. If you are pregnant, NHS guidance says to have no more than 200mg of caffeine a day from all sources. | For an evening gathering, I want to account for caffeine I have already had as well as the drink I take along. |
| Serving format | Check whether the product is ready to drink or needs water and stirring, and follow its storage instructions. Count the servings you need before choosing a multipack. | I may need drinks that can be handed out straight away, rather than a concentrate or powder that must be mixed. |
What can catch you out?

Treating “strong” as a caffeine figure
Flavour intensity and caffeine content describe different things. Jimmy's calls Strong its strongest iced coffee and claims an extra hit of caffeine, but that wording does not give an amount per can.
If you need to keep track of caffeine, look for an amount per serving on the current pack rather than relying on the name or flavour description.
-
Assuming cold brew is black coffee
Cold brew can also be sold as a milk or oat latte. M&S Classic Latte contains semi-skimmed milk, while its dairy-free Oat Latte has a stated coeliac and wheat-allergy limitation.
Decide whether you want black coffee or a latte, then check the ingredients and allergen statement for the specific drink.
-
Buying a case without planning how to serve it
A multipack provides several servings, but prepared drinks and products that need mixing call for different arrangements at an event.
Work out how many drinks you need, whether water and cups will be available, and how the chosen product must be stored.
Relevant brand references
These brands illustrate different drink formats and label details; their inclusion does not imply that each product appears in the Joybuy selection below.
Jimmy's Iced Coffee
Its Strong SlimCan is a 250ml milk-based iced coffee for shoppers considering a bolder-tasting, ready-to-drink option.
- Jimmy's describes Strong as its strongest iced coffee, with bold flavour and an extra hit of caffeine; these are the maker's descriptions.
- It contains semi-skimmed milk. The flavour claim does not provide a caffeine amount per serving.
M&S
Its Classic Latte and Oat Latte Cold Brew drinks offer milk-based and dairy-free latte formats.
- M&S describes both products as containing a double shot of espresso.
- Classic Latte contains milk. M&S says Oat Latte is unsuitable for people with coeliac disease or a wheat allergy.
Sandows
A black ready-to-drink cold brew to consider instead of a creamy latte.
- Coffee Friend UK lists the drink as made from coffee and filtered water, and describes it as dairy-free and sugar-free.
- Check the current bottle's ingredients and nutrition information when those details affect your choice.
Emmi Caffè Latte
A chilled, milk-based iced-coffee reference for shoppers considering coffee drinks beyond cold brew.
- Sainsbury's lists 87mg caffeine per 230ml cup for Emmi Caffè Latte Cappuccino.
- Sainsbury's describes it as iced coffee with cocoa, not as cold brew; it should not be treated as a like-for-like cold-brew option.
Joybuy coffee options
These Joybuy options include cold-water coffee to mix before serving and a ready-to-drink iced espresso coffee. Check the preparation and storage requirements if you are taking drinks to a Bonfire Night gathering; the iced espresso option is not identified as cold brew.

J.ZAO Extra-Strong Americano Cold Brew Coffee Liquid, 10 × 25ml pouches
The individual pouches can be taken to a gathering, but this is a concentrate, not a ready-to-drink coffee. The product directions call for one 25ml pouch mixed with about 200ml water; the description lists 0g sugars per 100ml. “Extra-Strong” does not give a caffeine amount per prepared serving, so check the pack if that amount matters.
No image available
J.ZAO Freeze-Dried Instant Black Coffee Powder, 24 × 2g capsules
The 2g capsules make a black coffee with cold or hot water, so you will need water and something to stir it with. This is freeze-dried instant coffee rather than ready-to-drink cold brew. Check the selected pack for its flavour variant and caffeine information before buying if either affects your choice.
No image available
Office Fish Roasted Sweet Potato Flavoured Cold Brew Freeze-Dried Black Coffee Powder, 18g
This flavoured powder offers single servings to prepare at the gathering rather than a plain, ready-to-drink coffee. The directions specify one sachet mixed with 150–180ml cold water; the description identifies sweet potato concentrate alongside Arabica coffee. Check the pack for caffeine information if you need an amount per drink.

Starbucks Doubleshot Espresso Iced Coffee, 12 × 200ml bottles
The 200ml bottles are ready to drink, but this is described as iced espresso coffee, not cold brew. The product information lists milk, 8.5g sugars per 100ml and chilled storage at 2–8°C. It also warns that the drink is unsuitable for children, pregnant or breastfeeding women, and people sensitive to caffeine; check the pack for the caffeine amount.
Common questions
Does “strong” cold brew always contain more caffeine?
No: a strong flavour description does not establish a caffeine amount. Waitrose discusses coffee strength in terms of flavour intensity, while Jimmy's describes an extra hit of caffeine without giving a comparable milligram figure in that claim. Use caffeine information per serving when the amount affects your decision.
What can I choose if I avoid dairy?
M&S describes its Oat Latte Cold Brew as dairy-free, and Coffee Friend UK lists Sandows as a dairy-free black cold brew. They are different drink formats: M&S also says its oat latte is unsuitable for people with coeliac disease or a wheat allergy, so check the current pack against your requirements.
How should I compare sugar information?
Start with nutrition figures stated on the same basis, then consider how much of each drink you will have. Keep per 100g and per 100ml figures distinct rather than treating them as interchangeable, and check the whole-container information where it is stated.
What caffeine guidance applies during pregnancy?
NHS guidance says not to have more than 200mg of caffeine a day during pregnancy. That daily amount includes caffeine from sources other than the coffee taken to the gathering; also follow any warning on the specific product pack.
Can I use an online ingredients list to check an allergy?
Check the current product label and allergen information for the drink you are buying. This matters particularly when choosing an oat latte: M&S states that its Oat Latte Cold Brew is not suitable for people with coeliac disease or a wheat allergy.
