Who is each format for?

Black-coffee drinkers checking carbohydrate

Unsweetened black cold brew keeps milk and sweetened flavourings out of the drink. Check the individual product’s ingredients and its declared carbohydrate and sugars: Coffee Friend UK lists both as 0 g per 100 ml for Sandows Cold Brew Coffee.

Dairy-free latte drinkers

An oat-based cold brew offers a latte format without dairy, but “no added sugar” does not mean zero carbohydrate. Sainsbury’s lists 7 g carbohydrate and 4.8 g sugars per 100 ml for Rodd’s Original Latte, so the serving size matters when reading its nutrition panel.

Shoppers drawn to strong-flavour descriptions

A ready-to-drink latte may appeal if you prefer milk and a robust coffee flavour. Marks & Spencer describes its Classic Latte Cold Brew as robust and containing a double shot of espresso, but those words do not give a caffeine amount to compare with another drink.

What should you check before choosing?

Read the nutrition panel and ingredients first, then check the serving size and any caffeine declaration for the drink you intend to have.

Priority What to check Your needs
Carbohydrate and sugars Read both figures and their per-100-ml, per-100-g or per-serving basis. Coffee Friend UK lists 0 g of each per 100 ml for Sandows black cold brew; Marks & Spencer lists 5.0 g carbohydrate and 3.8 g sugars per 100 g for its Classic Latte Cold Brew. The different bases should not be treated as identical portions. I want to know what the amount I drink contributes to my carbohydrate count, rather than choosing by coffee style alone.
Added-sugar wording Check total sugars and carbohydrate alongside any “no added sugar” claim. Sainsbury’s lists Rodd’s oat latte as no added sugar, with 4.8 g sugars and 7 g carbohydrate per 100 ml. A dairy-free latte appeals to me, but I do not want to mistake “no added sugar” for zero sugars or zero carbohydrate.
Caffeine Look for a caffeine amount in mg and check whether it applies per 100 ml or per serving. Coffee Friend UK gives 40.5 mg per 100 ml for Sandows; Sainsbury’s displays 41 mg for Rodd’s without a clear serving basis in the product information cited here. Do not compare those figures as equivalent portions. By “strong”, I mean a known caffeine amount, not just a dark or robust coffee flavour.
Ingredients and preparation Check for milk, oat drink, sugar, syrups and flavourings. For a concentrate, also check the mixing instructions and the nutrition basis for the amount you prepare. Diabetes UK advises checking food labels or asking for nutritional information when choosing drinks. When I pick up a drink on the go—or mix one at home—I want the figures to reflect what will actually be in my cup.

Common label mistakes

  • Reading “no added sugar” as “no sugar”

    Ingredients can contribute sugars and carbohydrate even when no sugar has been added. Sainsbury’s lists Rodd’s Original Latte as no added sugar, yet its nutrition panel gives 4.8 g sugars and 7 g carbohydrate per 100 ml.

    Use the total sugars and carbohydrate lines, along with the serving size, before deciding how the drink fits your needs.

  • Using flavour words to judge caffeine

    “Strong”, “robust” and “double shot” do not provide a shared caffeine measure. Coffee Friend UK states 40.5 mg per 100 ml for Sandows, while the Marks & Spencer information cited here describes a double shot without giving caffeine in mg.

    If caffeine quantity affects your choice, look for a stated amount and confirm the portion it covers.

  • Comparing a concentrate with a ready-to-drink bottle

    A pouch mixed with water and a bottled latte are prepared differently. Adding milk or other ingredients also changes what ends up in the cup.

    Check the concentrate’s mixing instructions and the nutrition basis for your prepared serving rather than comparing its pouch directly with a ready-to-drink bottle.

Product and brand references

These references describe particular listed drinks, not every product made by each brand.

Sandows

Coffee Friend UK lists Sandows Cold Brew Coffee as a ready-to-drink black coffee made with fresh coffee and filtered water.

  • The listing declares 0 g carbohydrate, 0 g sugars and 40.5 mg caffeine per 100 ml.
  • Check the bottle label when buying, particularly if those figures determine your choice.

Rodd’s

Sainsbury’s lists Rodd’s Original Latte as a dairy-free oat cold-brew drink with no added sugar.

  • The product information describes a 12-hour cold brew and displays a 41 mg caffeine statement.
  • It lists 7 g carbohydrate and 4.8 g sugars per 100 ml; the basis for the displayed caffeine amount needs checking before a numerical comparison.

M&S Food

Marks & Spencer describes its Classic Latte Cold Brew as a milk-based chilled coffee with a double shot of espresso and a robust flavour.

  • Its product information identifies the coffee-and-milk format for shoppers choosing a ready-to-drink latte.
  • Sugar appears in the ingredients, and the nutrition information gives 5.0 g carbohydrate and 3.8 g sugars per 100 g. “Double shot” does not establish a comparable caffeine amount.

Nolo

Sainsbury’s lists Nolo Classic Cold Brew Oat Latte as a decaffeinated oat-based drink.

  • The listing states that it has no added sugar or sweeteners.
  • It still lists 4.2 g carbohydrate and 1.9 g sugars per 100 ml. As a decaffeinated option, it does not address a preference for a caffeine-forward drink.

Joybuy cold-brew option

This portioned black-coffee option is for mixing at home rather than drinking straight from a ready-to-drink bottle. Check the prepared serving if carbohydrate or caffeine quantity affects your choice.

J.ZAO Extra-Strong Americano Cold Brew Coffee Liquid, ten 25 ml pouches

J.ZAO Extra-Strong Americano Cold Brew Coffee Liquid, 25 ml × 10 pouches

The single-serve pouches suit someone preparing a black coffee at home rather than choosing a ready-to-drink latte. The product name states zero sugar, but that does not mean zero carbohydrate: check the carbohydrate figure and its basis for your prepared serving. “Extra-Strong” does not specify a caffeine amount, so check the pack if caffeine quantity matters to you.

Cold-brew questions

Is cold brew automatically suitable for someone managing diabetes?

No: the brewing method alone does not determine the drink’s carbohydrate or sugar content. Diabetes UK says there is no one-size-fits-all diet for people with diabetes, and its cold-brew recipe can be served sweetened or unsweetened. Check the particular drink’s ingredients, nutrition panel and serving size.

Does “no added sugar” mean a cold-brew latte is sugar-free?

No. Sainsbury’s lists Rodd’s Original Latte as having no added sugar, but also declares 4.8 g sugars and 7 g carbohydrate per 100 ml. Read the total figures on the nutrition panel as well as the front-of-pack wording.

What does the Sandows black cold-brew label say?

Coffee Friend UK lists fresh coffee and filtered water, with 0 g carbohydrate, 0 g sugars and 40.5 mg caffeine per 100 ml for Sandows Cold Brew Coffee. Confirm the figures on the bottle you buy, especially if you use them to assess your serving.

Does “double shot” tell me the caffeine amount in a latte?

No. Marks & Spencer uses “double shot” to describe its Classic Latte Cold Brew, but that description is not a caffeine amount in mg. For a numerical comparison, use products that state the caffeine quantity and the portion it applies to.
