Afternoon coffee drinkers watching sugars
If you would rather have black coffee than a sweet latte alongside afternoon tea, compare sugars in the drink as served. Milk, oat drinks and syrups added to a concentrate need to be counted separately.
Who might choose each type
People choosing decaf later in the day
A zero-sugar label tells you nothing about caffeine. Look for a drink described as decaffeinated when caffeine avoidance matters to your afternoon choice.
Dairy-free latte drinkers
An oat-based cold-brew latte may suit someone avoiding dairy, but its sugars, caffeine and other allergen information still need separate checks.
What to check before choosing
Compare the finished serving first, then decide whether caffeine, dairy ingredients or preparation format changes your choice.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Read sugars per 100ml and per prepared serving. Compare a concentrate at its stated dilution and include anything you add; do not treat “no added sugar” as 0g sugars. | I want to know how much sugar is in the coffee I will actually drink, particularly if I add milk or syrup alongside afternoon-tea food. |
| Caffeine | Check whether the drink is decaffeinated and look for a caffeine figure for the bottle or prepared serving. Sugar and caffeine declarations answer different questions. | For a later-afternoon cup, avoiding caffeine matters more to me than choosing a zero-sugar label. |
| Dairy and allergens | Read the exact ingredient and allergen statements. Check any milk or plant-based drink you plan to add to a black concentrate. | I prefer a latte without dairy, but I also need to check whether its other ingredients suit me. |
| Preparation and storage | Check whether the drink is ready to pour or needs dilution. Match bottle size to the stated refrigeration, use-by and after-opening instructions. | Some afternoons call for a ready-to-drink bottle; at other times, I would rather measure and dilute a concentrate myself. |
Cold-brew label traps
-
Reading “no added sugar” as “zero sugar”
Sainsbury's lists 4.8g sugars per 250ml serving for the Nolo decaf oat latte, although it is described as having no added sugar or sweeteners.
If the amount of sugar matters to your choice, use the sugars figure for the serving rather than the front-of-pack wording alone.
-
Comparing concentrate with a finished latte
Tesco Groceries lists 0g sugars for its unsweetened concentrate prepared with water. Adding milk, an oat drink or syrup changes what is in the finished glass.
Start with the stated dilution instructions, then check the nutrition and ingredients of anything you add.
-
Assuming dairy-free also means caffeine-free
Marks & Spencer lists 2.9g sugars and 34.6mg caffeine per 100ml for its vegan chilled oat cold-brew latte.
Check dairy status, sugars and caffeine separately instead of using one label to answer all three questions.
-
Choosing a large bottle without checking storage
Tesco's concentrate needs refrigeration after opening and has a stated four-week after-opening period. A chilled ready-to-drink latte has its own storage instructions and use-by date.
Choose a size you expect to use within the instructions on that product's pack.
Brand and retailer examples
Tesco finest
Tesco Groceries lists an unsweetened cold-brew concentrate for preparing black coffee with water.
- Its listed preparation uses 100ml concentrate and 100ml cold water; Tesco gives 0g sugars for the prepared 200ml glass.
- It is a concentrate, not a ready-to-drink latte. Any additions need to be considered separately.
M&S
Marks & Spencer lists both a cold-brew latte made with semi-skimmed milk and a vegan Plant Kitchen oat version.
- The oat latte offers a dairy-free choice for someone who wants a latte-style drink.
- M&S lists 2.9g sugars and 34.6mg caffeine per 100ml for the oat latte; its Classic Latte contains milk.
Nolo
Sainsbury's lists Nolo's decaffeinated, dairy-free cold-brew oat latte as a ready-to-drink option.
- It is described as decaffeinated and made without added sugar or sweeteners.
- The listed 250ml serving still contains 4.8g sugars from naturally occurring sources.
Sandows
Coffee Friend UK describes a 200ml ready-to-drink Sandows black cold brew made without dairy.
- The retailer lists 0g sugars per 100ml for this black coffee.
- It also lists 40.5mg caffeine per 100ml, so sugar-free does not mean decaffeinated.
Waitrose
Waitrose & Partners lists Vita Coco Cold Brew Coffee with Coconut Milk in a 330ml size.
- Its product name identifies a coconut-milk cold-brew option to consider alongside black coffee and oat lattes.
- Check the current pack's ingredients and nutrition before choosing it for a particular sugar or dietary requirement.
Joybuy cold-brew option
This coffee-liquid option is for measuring and diluting a black afternoon drink, rather than choosing a ready-to-drink oat latte.

J.ZAO Extra-Strong Americano Cold Brew Coffee Liquid, 25ml × 10 Pouches
The 25ml pouches let you measure a black afternoon coffee and dilute it with about 200ml water per pouch, adjusting the water to taste. Its nutrition table lists 0g sugars per 100ml; check any additions when comparing your finished drink. Check caffeine per prepared serving if that affects your choice. The product is named cold brew but is also described as instant-soluble, so check the brewing method if cold-brew extraction matters to you. For energy comparisons, check the pack because the product description and nutrition table give different figures.
Cold-brew questions answered
Does “no added sugar” mean a cold brew has 0g sugars?
No. Sainsbury's describes the Nolo decaf oat latte as having no added sugar or sweeteners, but lists 4.8g sugars per 250ml from naturally occurring sources. Read the sugars figure for the serving you plan to drink.
Will an unsweetened concentrate have 0g sugars once I make it into a latte?
That depends on what you add. Tesco Groceries lists 0g sugars for its concentrate prepared with water; milk, an oat drink or syrup needs to be checked separately when you make a latte.
Is a sugar-free cold brew necessarily decaffeinated?
No. Coffee Friend UK lists 0g sugars and 40.5mg caffeine per 100ml for Sandows black cold brew. Look for a drink described as decaffeinated when avoiding caffeine is the deciding factor.
What should I check about cold brew during pregnancy?
The NHS advises no more than 200mg caffeine a day during pregnancy, counting caffeine from all foods and drinks, including coffee and tea. Check the chosen cold brew's caffeine information as part of that daily total; Marks & Spencer states that its chilled oat cold-brew latte is not recommended during pregnancy.
Is a dairy-free oat cold brew suitable for every restricted diet?
No. Marks & Spencer describes its oat cold-brew latte as vegan and dairy-free, but states that it is not suitable for people with coeliac disease or those with soya or wheat allergy. Read the current product's allergen statement rather than relying on “dairy-free” alone.
