For a TV dinner, an unsweetened black concentrate makes sense if you want to control what goes into the finished drink: Tesco Finest lists 0g sugars per prepared 200ml glass when made as directed. If avoiding caffeine later in the day matters more, a decaffeinated oat latte is another route, but check its sugars and oat ingredients rather than treating “no added sugar” as sugar-free.
The useful distinction for a drink with dinner is whether you want control over the finished coffee, a decaffeinated ready-to-drink option or a latte that meets a particular ingredient requirement.
An unsweetened black concentrate lets you decide what, if anything, to add. Tesco Groceries lists 0g sugars and 12kcal for a prepared 200ml glass of Tesco Finest Unsweetened Cold Brew; milk or syrup would change the finished drink.
A product explicitly labelled decaffeinated is more relevant than choosing an ordinary cold brew by taste or format. Sainsbury’s lists Nolo Decaf Classic Cold Brew Oat Latte as a ready-to-drink decaffeinated option.
Check the requirement separately from the latte’s flavour or texture. Sainsbury’s describes Nolo as dairy-free, but it contains oat; Tesco’s Starbucks Skinny Latte listing describes it as lactose-free but not suitable for people with a milk allergy.
Choose it when: You want to prepare the coffee with water and control any additions.
Bear in mind: It takes preparation, and added milk or sweetener changes the nutrition of the finished drink.
Choose it when: A ready-to-drink, dairy-free coffee labelled decaffeinated fits your evening plans.
Bear in mind: Nolo contains oat and naturally occurring sugars despite its no-added-sugar label, according to Sainsbury’s.
Choose it when: You prefer a single-serve drink without diluting a concentrate.
Bear in mind: Dairy, lactose-free and oat versions address different ingredient needs; their sugar and caffeine information also needs checking product by product.
Start with the requirement that would rule out a drink, then compare nutrition for the amount you will actually pour or drink.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars and energy | Read “of which sugars” and energy for the prepared glass or whole can. Check the ingredients if you want to distinguish unsweetened coffee from a sweetened latte. | I want to know what the coffee contributes alongside dinner, including anything I add. Tesco Groceries lists 0g sugars and 12kcal per prepared 200ml glass of its Finest Unsweetened concentrate. |
| Caffeine | Look for an explicit decaffeinated label or a stated caffeine amount and serving size. Do not treat a concentrate as a ready-to-drink serving. | For a later meal, I may prefer a drink labelled decaffeinated rather than assume every cold brew has similar caffeine content. |
| Milk and oat ingredients | Read the ingredient and allergen statements. Check dairy-free, lactose-free and oat requirements separately on the exact product. | I need the latte base to fit the ingredients I avoid; “lactose-free” alone does not tell me whether a drink contains milk. |
| Preparation and storage | Check dilution directions, pack size and instructions after opening. For a can, compare nutrition for the amount you expect to drink. | Sometimes I want to open a drink with dinner; at other times, I would rather mix a concentrate and choose my own additions. |
A latte can contain naturally occurring sugars even when labelled no added sugar. Sainsbury’s describes Nolo as containing naturally occurring sugars.
Compare “of which sugars” for the whole drink or the amount you will serve, rather than relying on the front-of-pack phrase.
Caffeine information differs between products; Tesco’s Solo espresso listing carries a warning for people sensitive to caffeine and for pregnant or nursing women.
Check the caffeine and serving information on the exact pack. If you want to avoid caffeine with an evening meal, look for a product explicitly labelled decaffeinated.
These labels do not answer the same ingredient question. Sainsbury’s lists Nolo as dairy-free and containing oat, while Tesco says its lactose-free Starbucks Skinny Latte is not suitable for people with a milk allergy.
Read the current ingredient and allergen statement for the particular drink, even if you have bought it before.
A concentrate’s prepared glass and a ready-to-drink can are different amounts of drink. A per-100ml figure does not by itself describe a whole can.
Compare the amount you expect to consume: the prepared serving for a concentrate, or the relevant portion of a can or bottle.
These examples show why it helps to compare individual drinks rather than assume every cold brew from a retailer or maker has the same ingredients.
Tesco Groceries lists both unsweetened and sweetened cold-brew concentrates.
Sainsbury’s lists ready-to-drink cold-brew-style oat lattes, including a decaffeinated Nolo option.
M&S lists a ready-to-drink Classic Latte Cold Brew made with semi-skimmed milk.
Waitrose & Partners lists chilled dairy coffee drinks such as Emmi Caffè Latte Cappuccino.
Sandows London says it makes cold-brew coffee in its London brewery.
This Joybuy option is a portioned black cold-brew concentrate for mixing at home, not a ready-to-drink or decaffeinated latte.

The individual pouches suit mixing a black coffee with water for dinner; the product name labels this dark-roast variant zero sugar. Follow the pack’s dilution directions, and check its caffeine and energy information if either affects your evening choice.
No. A drink labelled no added sugar can still contain naturally occurring sugars, as Sainsbury’s notes for Nolo. Read “of which sugars” for the portion you will drink rather than treating the two phrases as interchangeable.
If you want to avoid caffeine, choose a drink explicitly labelled decaffeinated and check the exact pack. Ordinary cold brew and concentrates should not be assumed to contain the same amount of caffeine. During pregnancy, NHS guidance says not to have more than 200mg of caffeine a day from all sources.
An unsweetened concentrate prepared with water lets you decide whether to add milk or sweetener. Tesco Groceries lists 0g sugars per prepared 200ml glass of Tesco Finest Unsweetened Cold Brew; any additions need to be considered separately.
Not on the strength of “lactose-free” alone. Tesco’s Starbucks Skinny Latte listing says the drink is lactose-free but not suitable for people with a milk allergy. Check the product’s current ingredient and allergen statement for the requirement you need to meet.
