Night workers packing separate drinks
Individually portioned cans are convenient to pack for several shifts. Check the preparation description if you specifically want cold brew: a canned iced espresso drink is a different choice.
Who might choose each format?
Shoppers set on cold brew
If cold-brew preparation is the deciding factor, consider whether a ready-to-drink single can or a concentrate you can mix at home or work fits your routine.
Shoppers checking ingredients and allergens
Read the label of the exact drink before stocking up. Tesco’s Starbucks Doubleshot iced coffee contains milk; M&S says its Oat Latte Cold Brew Coffee is not suitable for coeliacs or people with a wheat allergy.
What should you check before buying?
Decide whether preparation method or separate ready-to-drink portions matters more, then check the label and storage instructions against your shift routine.
| Priority | What to check | Your needs |
|---|---|---|
| Preparation method | Look for an explicit cold-brew or cold-water extraction description. Tesco describes its Starbucks Doubleshot multipack as espresso with milk; Tesco Finest describes its concentrate as cold-water extracted. | If I specifically want cold brew, a chilled can or an iced-coffee label alone will not settle the choice. |
| Ingredients and allergens | Compare the exact ingredients, sugars per 100ml and allergy statement. M&S describes its Oat Latte Cold Brew Coffee as dairy-free but says it is unsuitable for coeliacs and people with a wheat allergy. | I need to know whether the particular drink fits my ingredient or allergen requirements, rather than judging it by the words ‘oat’ or ‘cold brew’. |
| Portions and storage | Check the number and size of portions, whether mixing is required and the instructions after opening. Tesco lists a 4 × 200ml Starbucks can pack; its 500ml cold-brew concentrate uses 100ml concentrate and 100ml cold water per glass and must be refrigerated after opening. | Separate cans work for the shifts when I want to pack a drink without mixing it. Concentrate is an option if I can prepare each glass and store the opened bottle as directed. |
| Caffeine timing | Check the drink’s caffeine information and plan when you will have it. NHS Thames Valley and Wessex Intensive Care Medicine School advises stopping caffeine at least four hours before a night shift ends because it may affect daytime sleep. | For a shift that ends before I go to bed, I want to plan my last caffeinated drink rather than opening another can near the end. |
Buying mistakes to avoid
-
Assuming iced coffee means cold brew
That can lead to a different drink from the one you intended: Tesco describes its Starbucks canned multipack as espresso with milk, while its cold-brew concentrate is cold-water extracted.
Check the preparation description on the exact product if cold brew is a requirement.
-
Leaving a convenient can until the end of the shift
Caffeine may affect daytime sleep after night work. NHS Thames Valley and Wessex Intensive Care Medicine School advises stopping it at least four hours before the shift ends.
Plan when you will have a caffeinated drink, including any can packed for later in the shift.
-
Treating an oat-based drink as suitable for every allergy requirement
M&S describes its Oat Latte Cold Brew Coffee as dairy-free but states that it is not suitable for coeliacs or people with a wheat allergy.
Read the current allergy statement on the exact product rather than relying on ‘oat’ or ‘plant-based’ wording.
-
Choosing concentrate without a preparation plan
Concentrate is not a ready-to-drink can. Tesco’s cold-brew concentrate is mixed with cold water and must be refrigerated after opening and consumed within four weeks.
Choose it when you can mix a drink and follow those storage instructions across your shifts.

Questions about coffee for night shifts
Is a multipack of canned iced coffee necessarily cold brew?
No. Tesco describes its Starbucks Doubleshot Espresso Iced Coffee 4 × 200ml pack as espresso with milk. Check for a cold-brew preparation description on the exact drink if that distinction matters to you.
What if I want several servings of cold brew rather than separate cans?
Concentrate is an option if you can prepare and store it. Tesco directs shoppers to mix 100ml of its cold-brew concentrate with 100ml of cold water per glass, then refrigerate the bottle after opening and consume it within four weeks.
When should I stop having caffeine during a night shift?
NHS Thames Valley and Wessex Intensive Care Medicine School advises stopping caffeine at least four hours before the shift ends because it may affect daytime sleep. Consider that timing when deciding which drink to pack for the later part of a shift.
Is an oat cold-brew can suitable for coeliacs?
Do not assume so from the word ‘oat’. M&S states that its Oat Latte Cold Brew Coffee is not suitable for coeliacs or people with a wheat allergy; check the current allergy statement on any drink you are considering.
