Black cold-brew drinkers
If you want coffee without milk or added sweetener, start with the ingredients rather than the iced-coffee category name. Coffee Friend UK lists Sandows cold brew with coffee and filtered water as its ingredients.
Who is each format for?
Ready-to-drink latte shoppers
If you want the milk base already mixed in, compare plain dairy, oat and flavoured versions. M&S lists Classic, Oat and Caramel Latte Cold Brew drinks, with different ingredients and dietary considerations.
Shoppers who need an exact substitute
If oat rather than dairy, an unflavoured drink or a concentrate is essential, check the retailer’s substitution setting. Tesco, Sainsbury's and Waitrose describe ways to manage alternatives in online grocery orders.
What should you check before ordering?
Choose the drink format and milk base first, then check its label and the delivery settings for the exact item.
| Priority | What to check | Your needs |
|---|---|---|
| Flavour and sweetness | Read the ingredients for milk, sugar and flavouring. M&S lists 3.8 g sugars per 100 g for its Classic Latte Cold Brew and 3.6 g per 100 g for its Caramel Latte version; Coffee Friend UK lists 0 g sugars per 100 ml for Sandows black cold brew. These figures use different measurement bases. | I want either an unflavoured coffee, a latte or a deliberately caramel-flavoured drink—not just any result labelled iced coffee. |
| Milk and allergens | Check the exact ingredients and current allergen statement. M&S says its Oat Latte Cold Brew is dairy-free but is not suitable for coeliacs or people with a wheat allergy. | If I avoid milk or need to check wheat or coeliac suitability, the base and the product-specific warning matter more than a broad dairy-free description. |
| Ready to drink or mix | Confirm whether the item is a finished drink or a concentrate, and read any mixing directions. An iced-coffee category can contain both; not every iced coffee is cold brew. | A carton or can suits me when I want to drink it as supplied. A concentrate suits me when I want to add water, ice or milk myself. |
| Caffeine | Look for a caffeine declaration and check the amount for the portion you will drink. Coffee Friend UK lists 40.5 mg per 100 ml for its Sandows cold brew listing; Food Standards Scotland and the Food Standards Agency advise counting coffee alongside other caffeine sources. | I want to account for this drink alongside any other coffee, tea or caffeinated products I consume. |
| Delivery substitutions | Review whether alternatives are allowed and any shopper-note option. Waitrose describes an “Allow substitution” control; Tesco and Sainsbury's say unwanted substitutes can be refused at delivery. | If a different milk base, flavour or format would not work for me, I would rather control substitutions than accept a broadly similar iced coffee. |
What can go wrong with an online order?

Assuming every iced coffee is cold brew
Retailer iced-coffee categories also contain lattes, flavoured drinks and concentrates, so a category result may not be the black cold brew you intended.
Search for the required format, then confirm the product title, ingredients and preparation directions.
-
Assuming an oat latte meets every dietary requirement
M&S describes its Oat Latte Cold Brew as dairy-free but states that it is not suitable for coeliacs or people with a wheat allergy.
Check the allergen statement for the exact product delivered rather than relying on “oat” or “dairy-free” alone.
-
Leaving substitutions on for a non-negotiable choice
An alternative can change the milk base, sweetness, flavour or preparation format. Tesco, Sainsbury's and Waitrose provide substitution controls or explain how alternatives are handled.
Turn off substitutions where the retailer allows it if you need the exact item, and inspect any alternative before accepting it.
-
Judging caffeine by the drink’s temperature
A cold, ready-to-drink coffee can still contribute to caffeine intake. Coffee Friend UK lists 40.5 mg per 100 ml for its Sandows cold brew.
Check the declared amount and portion size where available, and consider other caffeine sources as advised by Food Standards Scotland and the Food Standards Agency.
