If bedtime is close, a caffeine-free drink is the more sensible choice than caffeinated cold brew: the European Food Safety Authority says a 100 mg dose close to bedtime may affect sleep in some adults. If you are drinking earlier, compare caffeine and total sugars for the whole bottle; “no added sugar” does not mean zero sugars.
Who is this choice for?
The useful starting point is whether coffee still fits the time of your supper, then which sugar figure and ingredients matter to you.
Late-supper shoppers who want coffee flavour
A no-added-sugar label does not answer the bedtime question. The European Food Safety Authority says caffeine close to bedtime may affect sleep in some adults, so consider the timing before choosing a caffeinated drink.
Black-coffee drinkers checking total sugars
The Coffee Friend UK listing for Sandows Cold Brew Coffee gives coffee and filtered water as ingredients and lists 0 g sugars per 100 ml. Check its caffeine figure as well if supper is late.
Oat-latte drinkers avoiding added sugar
Rodd’s Original Oat Latte offers a dairy-free cold-brew format with a no-added-sugar description. Sainsbury’s lists 4.8 g sugars per 100 ml, and the oat ingredients contain gluten, so the nutrition and allergen panels still matter.
What should you check before buying?
For a late supper, decide whether caffeine fits your bedtime first. Then compare total sugars and ingredients using the serving you would actually drink.
| Priority | What to check | Your needs |
| Caffeine timing |
Check caffeine per full bottle or prepared serving and when you plan to sleep. The European Food Safety Authority says 100 mg close to bedtime may affect sleep in some adults; Doncaster and Bassetlaw Teaching Hospitals NHS Foundation Trust advises avoiding caffeine in the hours before bed. |
I want a drink after supper, but I may be going to bed soon. A caffeine-free choice avoids adding another caffeine dose at that point. |
| Total sugars |
Read “of which sugars” as well as “no added sugar”, and compare equivalent quantities. Coffee Friend UK lists 0 g sugars per 100 ml for Sandows; Sainsbury’s lists 4.8 g per 100 ml for Rodd’s Original Oat Latte. |
If zero listed sugars matter to me, I need the nutrition figure, not just the front-of-pack claim. A no-added-sugar oat latte can still contain sugars. |
| Full-bottle caffeine |
Check whether the figure is per 100 ml or per bottle. Coffee Friend UK lists 40.5 mg per 100 ml for Sandows, approximately 81 mg in its 200 ml bottle; Rodd’s states 41 mg per 250 ml bottle. |
I might drink the whole bottle, so a per-100-ml figure alone will not tell me how much caffeine that drink contains. |
| Ingredients and format |
Check milk, oat, gluten and sweetener ingredients on the exact pack. Also distinguish a ready-to-drink bottle from a product that needs diluting with water. |
A dairy-free oat latte, black coffee and a milk-based iced espresso meet different ingredient preferences. If I am eating late, I also want to know whether the coffee needs preparing. |
Common buying mistakes
-
Reading “no added sugar” as “zero sugar”
Sainsbury’s lists 4.8 g sugars per 100 ml for Rodd’s Original Oat Latte despite its no-added-sugar description. That is 12 g in a 250 ml bottle.
Compare the nutrition panel’s “of which sugars” figure for the amount you intend to drink, rather than relying on the claim alone.
-
Letting the sugar claim decide a bedtime drink
A no-added-sugar cold brew can still contain caffeine. The European Food Safety Authority says caffeine close to bedtime may affect sleep in some adults.
If bedtime is near, consider a caffeine-free drink. Otherwise, compare caffeine per full serving and account for other caffeinated drinks you have had.
-
Assuming every creamy chilled coffee has the same ingredients
Rodd’s oat latte is dairy-free but contains gluten through its oat ingredients. Starbucks Doubleshot Espresso No Added Sugar contains milk and is described as espresso, not cold brew.
Read the ingredient and allergen information on the exact bottle, particularly when you need to avoid milk, gluten or sweeteners.
Relevant brands and drinks
These examples illustrate different label and ingredient choices; a brand name alone does not establish whether a particular drink suits a late supper.
Rodd’s
Rodd’s Original Oat Latte is a dairy-free, ready-to-drink cold-brew oat latte. Rodd’s states 41 mg caffeine per 250 ml bottle.
- Sainsbury’s describes this oat latte as no added sugar.
- Sainsbury’s lists 4.8 g sugars per 100 ml, and its oat ingredients contain gluten.
Sandows
Sandows makes cold brew; Coffee Friend UK lists its 200 ml black coffee with coffee and filtered water as ingredients.
- The Coffee Friend UK listing gives 0 g sugars per 100 ml.
- Its listed 40.5 mg caffeine per 100 ml works out to approximately 81 mg per 200 ml bottle, which matters when drinking close to bedtime.
Starbucks Chilled Coffee
Starbucks describes its Doubleshot Espresso No Added Sugar as an iced espresso drink with milk.
- Its UK product description confirms espresso, milk and no added sugar.
- It is an espresso option rather than an established cold-brew equivalent; check the pack’s caffeine and ingredients for a late-supper choice.
M&S Food
M&S lists an Oat Latte Cold Brew Coffee in a 250 ml dairy-free format.
- Its product information identifies the oat-latte format and provides a nutrition panel.
- M&S lists 1.5 g sugars per 100 g. If no added sugar is essential, check the claim on the exact product label.

The pouch format suits preparing a coffee with water at home.

Check caffeine per prepared serving before choosing it for late supper.

Questions about late-supper cold brew
Does “no added sugar” mean cold brew contains no sugar?
No. A drink described as no added sugar can still list sugars in its nutrition panel. Sainsbury’s lists 4.8 g sugars per 100 ml for Rodd’s Original Oat Latte, while Coffee Friend UK lists 0 g per 100 ml for Sandows Cold Brew Coffee. Compare the “of which sugars” figures for the quantity you would drink.
Should I have cold brew just before bed?
A caffeine-free drink is the more sensible choice if bedtime is close. The European Food Safety Authority says a 100 mg caffeine dose close to bedtime may affect sleep in some adults; a no-added-sugar claim does not change a drink’s caffeine content.
Which of Sandows and Rodd’s lists less caffeine per bottle?
Rodd’s states 41 mg caffeine in its 250 ml Original Oat Latte bottle. Coffee Friend UK lists 40.5 mg per 100 ml for Sandows Cold Brew Coffee, approximately 81 mg in its 200 ml bottle. Check the current pack when buying, as these figures apply to the specified drinks and sizes.
Is Rodd’s Original Oat Latte suitable if I avoid dairy or gluten?
Rodd’s describes Original Oat Latte as dairy-free, but its oat ingredients contain gluten. Check the current ingredient and allergen statement for the exact bottle if either restriction matters to you.
