Choose sparkling black cold coffee if you want carbonation rather than a creamy breakfast drink; choose a ready-to-drink latte for a milk- or oat-based coffee, or a concentrate if you want to prepare several drinks at home. Waitrose listed Union Sparkling Black Cold Coffee but marked it unavailable when checked on 2 October 2026, so confirm stock before planning around that can. Whichever format you choose, check the exact pack for ingredients, allergens, preparation instructions and caffeine information.
The useful distinction for a weekend breakfast is whether you want a fizzy drink to open, a creamy latte or coffee you prepare yourself.
A sparkling black cold coffee fits the brief if carbonation matters more to you than a milky texture. Waitrose listed Union Sparkling Black Cold Coffee in a 250 ml can, although it was marked unavailable when checked on 2 October 2026.
If you would rather have a creamy coffee than a fizzy one, compare the ingredients of dairy and oat-based options. M&S lists both a Classic Latte Cold Brew Coffee containing semi-skimmed milk and an Oat Latte Cold Brew Coffee.
A concentrate gives you a make-at-home format instead of individual ready-to-drink cans. Check its serving and dilution instructions before deciding how much to buy for the breakfast table.
Choose it when: You want a carbonated, black-coffee drink you can serve straight from a can.
Bear in mind: Waitrose marked its 250 ml Union listing unavailable when checked on 2 October 2026; check current stock and the pack before relying on it.
Choose it when: You prefer a creamy chilled coffee to carbonation.
Bear in mind: Latte recipes differ: M&S lists semi-skimmed milk in its Classic Latte and also offers an oat latte option.
Choose it when: You want to prepare drinks at home rather than serve individual cans.
Bear in mind: It is not a ready-made sparkling drink; follow the specific product’s preparation instructions.
Once you have chosen a format, compare the exact products rather than assuming that all drinks labelled cold brew have the same ingredients or preparation method.
| Priority | What to check | Your needs |
|---|---|---|
| Drink format | Look for an explicit sparkling description if you want carbonation. Distinguish a ready-to-drink can from a latte or a concentrate that needs preparation. | I would choose a fizzy black coffee over a creamy latte for this breakfast—or the reverse, if creaminess matters more. |
| Ingredients and allergens | Read the current ingredient list and highlighted allergens. M&S lists semi-skimmed milk in its Classic Latte Cold Brew Coffee; check any oat option’s own label separately. | Milk ingredients affect which drink I can choose, so the word “cold brew” alone is not enough. |
| Sugars and nutrition | Compare the label per 100 g and per serving, using the same measure across products. Do not assume a latte and a black coffee have the same recipe. | If sugars matter to my choice, I want the figures for the portion I will actually drink. |
| Caffeine | Check the caffeine amount for the serving and account for other sources. NHS guidance during pregnancy is not to exceed 200 mg of caffeine a day. | I may need to keep track of caffeine across coffee and other drinks, not just this breakfast serving. |
| Stock and preparation | Check stock for the retailer and location you will use. For concentrates, read the pack’s dilution and serving directions before making drinks. | I do not want to plan around a particular can without confirming it is available, or buy a concentrate without knowing how to serve it. |
M&S lists semi-skimmed milk in its Classic Latte Cold Brew Coffee. The brewing description does not tell you whether the finished drink contains milk or sugar.
Check the ingredients and highlighted allergens on the exact pack, including when choosing an oat or black-coffee alternative.
Waitrose marked Union Sparkling Black Cold Coffee unavailable when checked on 2 October 2026. A listing does not establish availability for your store or delivery slot.
Check your selected retailer’s current stock before making it part of the breakfast plan.
A concentrate needs preparation, so it does not offer the same open-and-serve convenience as a canned coffee.
Read the individual product’s dilution and serving instructions before using it, particularly if you intend to add sparkling water.
Serving a coffee cold or sparkling does not remove its caffeine. NHS guidance during pregnancy is not to exceed 200 mg of caffeine a day.
Check the product’s caffeine information and consider caffeine from other foods and drinks that day.
These examples show different cold-coffee formats; check each product’s current label and availability before choosing.

Consider these 25 ml × 10 pouches if you want to prepare individual cold-brew drinks for breakfast instead of serving ready-to-drink cans. Sparkling water and preparation are required for a sparkling serve; check the pack directions, caffeine information and nutrition label before relying on them.
No. Waitrose listed Union Sparkling Black Cold Coffee as a sparkling black-coffee drink, whereas M&S lists semi-skimmed milk in its Classic Latte Cold Brew Coffee. Choose by whether you want carbonation or a creamy milk-based drink, and check the exact product label.
Read the ingredient list and highlighted allergens on the pack you are buying. M&S Classic Latte Cold Brew Coffee contains semi-skimmed milk; do not assume another cold brew, including an oat option, has the same ingredients.
NHS guidance during pregnancy is not to exceed 200 mg of caffeine a day. Check the coffee’s caffeine amount with the manufacturer or on the pack, and account for caffeine from other foods and drinks.
Do not assume a concentrate is ready to drink. Read the specific product’s preparation and serving directions first; likewise, check those directions before mixing it with sparkling water.
