Who is this choice for?

The useful distinction for curry night is not simply black coffee versus latte: sugar, milk ingredients and the way you prepare the drink can each change which product fits.

Hosts watching added sugar

If you plan to serve coffee alongside or after food, an unsweetened concentrate lets you decide whether to add milk or syrup. A ready-to-drink black cold brew avoids the mixing step, but check its own nutrition panel.

Dairy-free or vegan drinkers

Look for suitable wording and ingredients on the particular pack. Tesco Finest’s unsweetened concentrate is labelled suitable for vegans, while the Sandows black cold brew listing describes it as dairy-free. A milk-based latte does not meet the same requirement.

Drinkers who prefer a creamy coffee

If lactose is your concern, a lactose-free milk latte may be an option; it is still a dairy drink. If sugars matter too, read the nutrition panel even when the front says ‘no added sugar’.

What should you check?

Choose the format you would actually serve, then compare the complete drink rather than judging every product by its cold-brew name or a per-100ml figure alone.

Priority What to check Your needs
Sugars and calories Compare sugars and calories for the glass, bottle or can you will serve. For a concentrate, follow its dilution directions and count any milk, plant milk or syrup added. Tesco Groceries lists 0g sugars for its Finest unsweetened concentrate prepared with equal parts concentrate and water; it lists 11.0g sugars for a 250ml Brown Sugar Cold Brew Latte can. I want to know what the finished coffee contributes to the meal, not just what is in the black coffee base.
Milk and lactose Check the ingredient list and the exact dairy-free, vegan or lactose-free wording. Waitrose & Partners describes Starbucks Multiserve Skinny Latte as a lactose-free milk drink with added sweetener and naturally occurring sugars. If I avoid dairy, lactose-free milk is not a substitute. If I can have milk but want to avoid lactose, I still need to check the drink’s sugars.
Caffeine Read the caffeine figure and its unit, then relate it to the amount you will drink. Coffee Friend UK lists 40.5mg per 100ml for Sandows black cold brew. Where a caffeine figure is not on the pack, do not assume that a small serving contains little caffeine. For coffee after an evening meal, I want to judge the serving against my caffeine needs and any other caffeinated drinks I have had.
Current label Check ingredients, allergens, nutrition and preparation instructions on the pack you are serving. GOV.UK notes that traffic-light labels, where provided, help compare calorie, fat, sugar and salt content. When serving guests with dietary restrictions, I need to check the actual pack rather than rely on a product name or an earlier listing.

Common label mistakes

  • Assuming ‘cold brew’ tells you the sugar content

    A cold-brew latte can contain added sugar and milk. Tesco Groceries lists 11.0g sugars and 3.6g saturates per 250ml can of its Finest Brown Sugar Cold Brew Latte, while its unsweetened concentrate lists 0g sugars when prepared with water as directed.

    Compare the serving you intend to drink. If you start with an unsweetened base, include any syrup or milk you add.

  • Treating lactose-free as dairy-free or no-added-sugar as sugar-free

    Waitrose & Partners describes Starbucks Multiserve Skinny Latte as a lactose-free milk drink with no added sugar, but says it contains naturally occurring sugars. Neither claim makes it dairy-free or sugar-free.

    Match the label to the requirement: check ingredients for dairy avoidance, lactose wording for lactose avoidance and the nutrition panel for sugars.

  • Overlooking caffeine in a measured serving

    Caffeine figures can be stated per 100ml rather than per bottle or prepared glass. Tesco Groceries lists 159mg per 100ml for Solo ready to go Espresso and carries a warning for children, pregnant or nursing women, and people sensitive to caffeine.

    Check the amount you will actually drink and follow product warnings. For pregnancy, NHS guidance says total caffeine intake should not exceed 200mg a day, counting sources beyond coffee too.

  • Serving from an older product description

    Ingredients and nutrition information can change, which matters when a guest needs to avoid a particular ingredient.

    Before serving, check the physical pack for ingredients, allergens, nutrition, storage and use-by instructions.

Brand and product-line references

These examples show why the exact drink matters more than the brand name: black concentrates, bottled black coffee and milk lattes answer different needs.

Tesco Finest

Tesco Groceries lists both an unsweetened cold-brew concentrate and a Brown Sugar Cold Brew Latte.

  • The concentrate is labelled suitable for vegans and lists 0g sugars when prepared with water as directed.
  • The 250ml Brown Sugar latte contains whole milk and lists 11.0g sugars and 3.6g saturates; it is a different choice from the unsweetened concentrate.

Sandows

Coffee Friend UK lists a ready-to-drink black cold brew in a 200ml bottle.

  • The listing describes this drink as sugar-free and dairy-free, with 0g sugars.
  • It lists 40.5mg caffeine per 100ml, so check how much of the bottle you plan to drink.

Solo

Tesco Groceries lists Solo ready to go Espresso as a coffee drink without milk or sugar.

  • Its listing distinguishes it from milk-based iced coffees.
  • The listing states 159mg caffeine per 100ml and warns against use by children, pregnant or nursing women, and people sensitive to caffeine. Check the exact Solo product rather than assuming all its coffee drinks have the same strength.

M&S

Marks & Spencer lists a Classic Latte Cold Brew Coffee made with semi-skimmed milk.

  • It is a ready-to-drink, milk-based option for someone seeking a latte rather than black coffee.
  • Its ingredients include sugar and the listing gives 3.8g sugars per 100g. It is not a dairy-free or zero-sugar option.

Starbucks

Waitrose & Partners lists Starbucks Multiserve Skinny Latte No Added Sugar as a milk-based iced coffee with added sweetener.

  • The listing describes it as lactose-free for shoppers who want a milk latte without lactose.
  • It remains a milk drink and contains naturally occurring sugars; ‘no added sugar’ does not mean sugar-free.

Cold-brew questions

Does an unsweetened concentrate stay sugar-free when made into an iced latte?

Not necessarily. Tesco Groceries lists 0g sugars for its Finest unsweetened concentrate prepared with equal parts concentrate and water, but milk, milk alternatives or syrup change the finished drink. Check each addition and the serving you make.

Does ‘no added sugar’ mean a milk-based iced coffee has no sugars?

No. Waitrose & Partners says its listed Starbucks Multiserve Skinny Latte has no added sugar but contains naturally occurring sugars. Read the nutrition panel if the total sugars in your drink matter.

What cold brew can I serve someone avoiding dairy?

Choose a product explicitly labelled dairy-free or suitable for vegans, then check the current ingredients and allergens. Tesco Finest’s unsweetened concentrate is labelled suitable for vegans, and Coffee Friend UK describes Sandows black cold brew as dairy-free. A lactose-free milk latte is still a dairy drink.

What caffeine check matters for cold brew after curry?

Use the caffeine amount on the label and the volume you will drink, rather than assuming all cold brews have the same content. Coffee Friend UK lists 40.5mg per 100ml for Sandows black cold brew. During pregnancy, NHS guidance sets a limit of 200mg caffeine a day from all sources, not just this drink.
