Who is each option for?

Shoppers looking for zero sugars

If zero sugars are essential, read the nutrition panel rather than relying on “cold brew” or “unsweetened” in the name. Coffee Friend UK describes Sandows black cold brew as sugar-free and dairy-free.

Dairy-free or vegan latte drinkers

M&S labels its Plant Kitchen Chilled Cold Brew Oat Latte vegan and dairy-free. Check its sugars separately: a dairy-free label is not a zero-sugar claim.

Shoppers choosing between now and later

A ready-to-drink bottle suits one drink without preparation. Tesco lists a cold-brew concentrate for making drinks at home, where you can choose the liquid to add.

What should you check before choosing?

Decide whether you need a drink now or one to mix later, then check the label for the dietary details that matter to you.

Priority What to check Your needs
Sugars Read the sugars figure and its stated basis, such as per 100 ml or per 100 g. Check ingredients as well as an “unsweetened” name. I want a zero-sugar drink, not just one whose name sounds less sweet. Coffee Friend UK describes Sandows black cold brew as sugar-free; the M&S Classic Latte ingredient list includes sugar.
Dairy and vegan labels Check the dietary label, ingredients and allergen information separately. M&S lists semi-skimmed milk in its Classic Latte and labels its Plant Kitchen oat latte vegan and dairy-free. A plant-based latte might suit me, but I still need to check its sugars. If I am avoiding milk, I need to distinguish the oat latte from the dairy-milk version.
Caffeine Look for caffeine per 100 ml or serving, then account for how much of the bottle you plan to drink. Check any high-caffeine warning. I may have more than one caffeinated drink today, so the bottle size matters as well as the figure on its label. M&S flags high caffeine on its Plant Kitchen oat latte.
Preparation Check whether the coffee is ready to drink or must be diluted. For concentrate, read the mixing and storage directions and consider what you will add. If I want a coffee straight after shopping, I need a ready-to-drink bottle. If I am making several drinks at home, a concentrate gives me a choice of added liquid.

What is easy to overlook?

  • Assuming cold brew means zero sugars

    Cold brewing describes how the coffee is prepared, not the finished drink’s sugar content. The M&S Classic Latte ingredient list includes sugar, while Coffee Friend UK describes Sandows black cold brew as sugar-free.

    For a zero-sugar purchase, check the sugars figure on the particular product’s nutrition panel and note whether it is given per 100 ml, per 100 g or per serving.

  • Treating dairy-free and sugar-free as the same claim

    M&S labels its Plant Kitchen oat latte vegan and dairy-free, but that does not establish that it contains no sugars.

    Read dietary claims, ingredients, allergen information and nutrition values separately against the requirement you are shopping for.

  • Checking caffeine for a serving but drinking the bottle

    A caffeine figure per 100 ml does not describe your total intake unless you account for the amount consumed. M&S gives its Plant Kitchen oat latte a high-caffeine warning.

    Check the pack’s caffeine figure, bottle volume and warning before deciding how much to drink; include other caffeinated drinks you plan to have.

  • Mistaking concentrate for a ready-to-drink coffee

    A concentrate needs mixing, and the liquid you add affects the finished drink’s ingredients and nutrition.

    Choose a ready-to-drink format if you need coffee without preparation. For concentrate, check its own label and mixing directions before buying.

Cold-brew questions

Does “unsweetened” cold brew mean zero sugars?

Not necessarily. Check the finished product’s sugars figure and ingredients rather than treating “unsweetened” in its name as a zero-sugar nutrition value. Tesco Groceries lists an Unsweetened Cold Brew Coffee Concentrate, while Coffee Friend UK explicitly describes Sandows black cold brew as sugar-free.

What can I choose if I want to avoid dairy?

Coffee Friend UK describes Sandows black cold brew as dairy-free and lists coffee and water as its ingredients. If you want a latte format, M&S labels its Plant Kitchen oat latte vegan and dairy-free; check its sugars and high-caffeine warning separately.

How do I compare caffeine between cold-brew bottles?

Use the caffeine figure on each bottle’s label together with the amount you intend to drink, and read any high-caffeine warning. A per-100-ml figure describes a different quantity from a full bottle; other caffeinated drinks also contribute to your daily total.

Should I buy a bottle or a concentrate for a quick top-up?

Choose a ready-to-drink bottle if you want coffee without mixing it. A concentrate suits preparation at home when you can add water, milk or a plant drink; check its dilution and storage instructions, along with the ingredients of anything you add.
