Sparkling cold brew is a chilled coffee drink, not a hot bedtime alternative. If you want coffee flavour close to bedtime, an explicitly decaffeinated product is the more relevant choice, but check its pack and preparation instructions rather than assuming that decaf means zero caffeine. A controlled study reported disrupted sleep after a 400 mg caffeine dose taken even six hours before bed; it does not establish the effect of every coffee drink.
If you want coffee flavour before bed, distinguish that preference from a reason to choose caffeinated coffee. A study published in the Journal of Clinical Sleep Medicine found disrupted sleep after a 400 mg caffeine dose taken six hours before bedtime; it did not test every drink or serving size.
Sparkling cold brew is a chilled, carbonated coffee format, not a hot-drink preparation method. Comunicaffe International reported a Sandows sparkling cold-brew soda launch in 2018; that report does not establish whether the product is currently sold.
Tesco lists explicitly named decaffeinated coffee concentrates alongside other iced-coffee concentrates. Check the designation on the exact product rather than relying on a flavour or cold-brew description.
Choose the occasion first: a sparkling cold brew and a still cold-brew concentrate are cold-coffee options, while a decaf product is the route to examine if the aim is an evening coffee-style drink with less caffeine.
| Priority | What to check | Your needs |
|---|---|---|
| Bedtime timing | Check the caffeine quantity for the intended serving, where stated, and when you plan to drink it. In a controlled study reported by the American Academy of Sleep Medicine, 400 mg of caffeine disrupted sleep when taken six hours before bed; that dose cannot be assumed for a particular can or cup. | I want a drink close to bedtime, so I do not want to mistake carbonation or cold brewing for decaffeination. |
| Decaf designation | Look for an explicit decaf designation on the exact pack. Check its serving and preparation instructions; do not interpret “decaf” as a guarantee of zero caffeine. | For an evening coffee-style drink, I would rather select a product labelled decaf than judge it by its flavour name. |
| Drink format | Check whether the product is ready to drink, a concentrate to prepare, or an instant coffee intended for a hot drink. Tesco describes its Finest cold-brew concentrate as cold-water extracted; this does not make it a ready-made hot drink. | A fizzy chilled coffee fits a different occasion from the hot drink I am planning before bed. |
| Product identity | Check the current product listing, ingredients and alcohol declaration. Sainsbury’s and Waitrose list cold-brew coffee liqueurs, which are different products from non-alcoholic sparkling coffee. | I want to be sure the item in my basket is the type of coffee drink I intended to buy. |
Neither term establishes that a coffee drink is decaffeinated. A controlled study published in the Journal of Clinical Sleep Medicine found that a 400 mg caffeine dose taken six hours before bed disrupted sleep, although it did not test every cold-brew product.
For a drink near bedtime, check for an explicit decaf designation and review caffeine information for the intended serving where it is given.
Sainsbury’s lists Tia Maria Cold Brew Coffee Liqueur, and Waitrose lists Mr Black Cold Brew Coffee Liqueur. Their cold-brew descriptions do not make them non-alcoholic sparkling coffees.
Read the full product name, category and alcohol-by-volume declaration before adding a search result to your basket.
Comunicaffe International reported Sandows’ sparkling cold-brew soda launch in 2018. That establishes the format at the time, not its current recipe or availability.
If you want sparkling cold brew, check a current product page for its ingredients, caffeine information and delivery or store options.
These examples help distinguish product formats; a brand’s inclusion here does not mean that a particular drink is suitable before bed.
Tesco Groceries lists both a Finest Unsweetened Cold Brew Coffee Concentrate and explicitly named decaffeinated concentrates in its iced-coffee range.
M&S lists an Oat Latte Cold Brew Coffee 250 ml in its chilled-drinks assortment.
Sandows describes itself as a London cold-brew coffee producer. Comunicaffe International reported its sparkling cold-brew soda launch in 2018.
These decaf coffee products are options to consider for a coffee-style hot drink. They are not sparkling cold brews; check each pack’s preparation directions and caffeine information for your intended serving.

Consider this if you want a portioned decaf cappuccino-style drink rather than a chilled, fizzy coffee. Check the pack’s preparation and allergen information if milk is a concern, and review the caffeine information for a prepared serving if you need to monitor intake.

This 100 g decaf instant coffee is another option for a prepared coffee-style drink rather than a sparkling cold brew. Check the pack for preparation directions and caffeine information relevant to your serving.
No: it is a chilled, carbonated coffee format. Fizz does not establish that it is decaffeinated. A controlled study reported by the American Academy of Sleep Medicine found disrupted sleep after 400 mg of caffeine taken six hours before bed, but that result does not specify the effect of every sparkling coffee serving.
Flavour is not a way to determine its caffeine content. Tesco describes its Finest cold-brew concentrate as less bitter than heat-extracted coffee, but that description does not identify it as decaffeinated. Check the exact product’s caffeine information instead.
Start with an explicit decaf designation, then check the intended serving, preparation directions and caffeine information where supplied. Tesco lists named decaffeinated concentrates, while the Joybuy options above are decaf coffees rather than sparkling cold brews.
UK government food-labelling guidance says drinks containing more than 150 mg of caffeine per litre must carry a high-caffeine warning. Do not treat the absence of that warning as proof that a coffee drink is caffeine-free or suited to your planned bedtime; check the product and serving information.
