Hosts choosing how to sweeten each drink
An unsweetened concentrate gives you a black-coffee base. Guests can then choose whether to add milk, a plant drink or syrup; those additions change the finished drink’s sugar and allergen profile.
Who is each option for?
Groups with different dairy and caffeine preferences
A plant-based latte can provide a dairy-free choice, but oat content still matters for some guests. If someone avoids caffeine, select a drink explicitly labelled decaffeinated rather than assuming an oat latte is decaf.
Hosts serving children or pregnant guests
Check the warning on each coffee drink and offer a non-caffeinated alternative. M&S labels its cold-brew oat latte as not recommended for children or pregnant or breast-feeding women; NHS pregnancy guidance also addresses caffeine from all sources during the day.
What should you check?
Choose the serving format first, then check the label for the dietary details that matter to your guests.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars and mixers | Check total sugars as well as added ingredients. Tesco Groceries lists 0g sugars for a prepared 200ml glass of its unsweetened concentrate; Sainsbury's lists 4.8g per 250ml for Nolo's no-added-sugar oat latte. Consider anything added after pouring. | I’d like guests to choose their own milk or sweetener rather than receive a pre-mixed latte. |
| Caffeine | Look for an explicit decaffeinated description or a caffeine statement. Sainsbury's describes Nolo as decaffeinated; M&S lists 34.6mg caffeine per 100ml for its oat latte and prints a warning for particular groups. | Some guests avoid caffeine, so I want a clearly identified decaf choice and a non-caffeinated drink. |
| Dairy and oats | Read the current ingredient and allergen information. Tesco Finest labels its black concentrate suitable for vegans; Nolo contains oat, and M&S states that its oat latte is not suitable for coeliacs. | A dairy-free drink would help, but I also need to check whether an oat-based option suits each guest. |
| Chilled storage | Check the pack’s temperature, opening and date instructions. M&S specifies 0°C to +5°C for its chilled latte; Sainsbury's says to refrigerate Nolo after opening and consume it within 24 hours. | I want to open chilled drinks when they are needed and keep the packaging available for storage and allergen checks. |
Common serving mistakes
-
Reading “no added sugar” as “zero sugar”
The terms answer different questions. Sainsbury's labels Nolo as having no added sugar or sweeteners, yet its nutrition panel lists 4.8g total sugars per 250ml. The NHS explains that a total-sugars figure can include naturally occurring sugars.
Check the ingredients and the total-sugars figure, then account for any syrup or sweetened mixer added at the table.
-
Assuming an oat latte suits every guest
An oat-based drink is not necessarily decaffeinated or suitable for someone with coeliac disease. M&S lists caffeine in its cold-brew oat latte and states that the product is not suitable for coeliacs.
Check the current caffeine, ingredient and allergen statements, and keep a separately identified decaf or non-caffeinated choice for guests who need one.
-
Opening chilled drinks well before serving
Storage instructions differ: Sainsbury's says to consume Nolo within 24 hours of opening, while M&S specifies a refrigeration range for its chilled latte. The Food Standards Agency distinguishes use-by dates, which relate to food safety, from best-before dates, which relate to quality.
Follow each pack’s refrigeration and opened-life instructions, and check any use-by date before serving.
Brand and product references
These examples show how particular product labels differ; check the pack of the drink you intend to serve.
Tesco Finest
Its unsweetened cold-brew concentrate is a base for drinks mixed to order.
- Tesco Groceries lists 0g sugars per prepared 200ml glass and labels the concentrate suitable for vegans.
- It requires dilution; milk, syrup or other additions change the finished drink.
Nolo
Its single-serve decaffeinated cold-brew oat latte is a ready-to-drink dairy-free option.
- Sainsbury's describes it as decaffeinated and made without added sugar or sweeteners.
- It contains oat and lists 4.8g total sugars per 250ml, so it is not a zero-sugar drink.
M&S Plant Kitchen
Its chilled cold-brew oat latte is a ready-to-pour vegan, dairy-free option.
- It can be poured without diluting a concentrate or choosing a separate milk.
- M&S lists 34.6mg caffeine per 100ml, says it is not suitable for coeliacs and warns against serving it to children or pregnant or breast-feeding women.
Rodd's
Its oat cold-brew latte is an individual dairy-free drink with caffeine.
- Sainsbury's lists 41mg caffeine per bottle, making its caffeine content identifiable on the listing.
- It contains oat, lists 4.8g sugars per 100ml and needs chilled storage.

J.ZAO Extra-Strong Americano Cold Brew Coffee Liquid, 10 × 25ml pouches
Individual pouches let you prepare black coffee and offer additions separately. The listed nutrition gives 0g sugars per 100ml, and the preparation directions say to add about 200ml water per pouch. Check the current pack’s caffeine and allergen information before serving guests with related requirements; this concentrate is not a ready-to-pour latte.
Frequently asked questions
Does “no added sugar” mean a cold-brew oat latte has no sugar?
No. Sainsbury's labels Nolo as having no added sugar or sweeteners, but lists 4.8g total sugars per 250ml. The NHS explains that total sugars on a label can include naturally occurring sugars as well as free sugars.
How can I serve cold brew with the sweetener left up to guests?
Use an unsweetened concentrate and offer milk and sweeteners separately. Tesco Groceries lists 0g sugars per prepared 200ml glass for its concentrate; check the ingredients and nutrition information for any mixers, as they change the finished drink.
Is a standard cold-brew oat latte suitable for pregnant guests?
Do not assume so: M&S specifically labels its cold-brew oat latte as not recommended for pregnant or breast-feeding women. NHS guidance says pregnant people should not have more than 200mg caffeine a day from all sources. Provide a non-caffeinated choice and retain the pack warning for guests to check.
Does dairy-free mean an oat cold brew is suitable for coeliacs?
No. Dairy-free status does not establish coeliac suitability: Nolo contains oat, and M&S states that its oat latte is not suitable for coeliacs. Check the current packaging and allergen information for the specific drink.
When should I open chilled cold-brew drinks for a party?
Follow each pack’s storage and opened-life instructions rather than opening everything in advance. Sainsbury's says to refrigerate Nolo after opening and consume it within 24 hours; M&S specifies 0°C to +5°C for its chilled latte. Check any use-by date before serving.
