People comparing sugars
If you want a drink with 0g total sugars, check the nutrition panel rather than relying on “no added sugar”. An oat latte can carry that claim while still listing sugars.
Who these choices suit
The useful distinction is between what the drink claims on the front and what its ingredients and full-serving figures say.
People watching caffeine
A decaf option and a caffeinated cold brew answer different needs. Check the amount in the portion you will drink, particularly when the bottle contains several servings.
Plant-based and dairy-avoiding shoppers
Dairy-free or vegan wording can help narrow the choice, but it does not settle oat, wheat, soya or coeliac-related suitability. Read the current product’s allergen statement.
What to check before buying
Start with the requirement that would rule a drink out, then compare figures for the amount you expect to drink—not just the per-100ml panel.
| Priority | What to check | Your needs |
|---|---|---|
| Total sugars | Read sugars per 100ml and for the full can or bottle. Check the ingredients separately for added sugar. | I want to distinguish 0g total sugars from “no added sugar”, which can still describe a drink containing sugars from its ingredients. |
| Caffeine | Check whether the drink is decaf and, for a caffeinated product, whether its figure is per 100ml or per serving. Account for the volume you will drink. | If I am limiting caffeine, the label needs to fit with other caffeinated drinks I have that day. The NHS advises pregnant people not to exceed 200mg of caffeine a day. |
| Ingredients and allergens | Read the named ingredients and current allergen statement; do not substitute a vegan or dairy-free claim for an allergy check. | A dairy-free coffee may suit my dairy-avoidance preference, but I still need to check oat, wheat and soya information where relevant. |
| Lunch format | Check the pack volume, whether it is ready to drink or needs mixing, and any chilled-storage instructions. | For a single lunch, I want a portion I can use as intended. A concentrate needs water, while a multi-serve bottle needs portioning. |
| Food alongside the drink | Check what the purchased serving contains rather than treating coffee flavour, fibre or bottle size as evidence of a complete meal. | I am choosing a drink to go with lunch. The NHS Eatwell Guide describes balance across food groups over a day or week, not as something a coffee bottle establishes on its own. |
Common buying mistakes
-
Reading “no added sugar” as “zero sugar”
Sainsbury’s lists 4.8g sugars in a 250ml Nolo decaf oat latte despite its no-added-sugar description; its Rodd’s oat latte also lists sugars.
Use the total-sugars figure for the amount you will drink. If 0g total sugars is your requirement, check for 0g on that product’s nutrition panel.
-
Assuming cold brew or plant-based coffee is low in caffeine
Caffeine varies by product and portion. Marks & Spencer lists 34.6mg per 100ml for its 750ml oat latte, so drinking the whole bottle would amount to about 259.5mg.
Calculate from the volume you will actually have and include other caffeine consumed that day. The NHS advises pregnant people not to exceed 200mg a day.
-
Treating vegan or oat-based as an allergen guarantee
Marks & Spencer labels its Plant Kitchen oat latte vegan but states that it is unsuitable for coeliacs and for people with soya or wheat allergy.
Check the current ingredients and allergen wording for the exact drink, even if its dietary description otherwise fits.
-
Letting a coffee take the place of lunch by default
A drink’s serving size or added ingredients do not, by themselves, establish it as a complete meal. The NHS Eatwell Guide considers food-group balance across the day or week.
Choose cold brew for its drink characteristics and plan lunch separately. If a coffee-based product is presented as a complete meal, assess that specific product’s intended use and nutritional information.
Brand and product-line references
These examples show why the exact drink matters more than the brand name: black coffee, decaf oat lattes and multi-serve oat lattes have different labels to check.
Sandows
A ready-to-drink black cold brew for someone looking for a coffee-and-water formulation.
- Coffee Friend UK lists 0g sugars per 100ml for its 200ml Sandows cold brew.
- The same listing gives 40.5mg caffeine per 100ml and 0g protein and fibre.
Nolo
A decaf, dairy-free oat latte for someone prioritising reduced caffeine over a black-coffee format.
- Sainsbury’s describes the 250ml can as decaffeinated, with no added sugar or sweeteners.
- The can still lists 4.8g sugars and contains oat.
Rodd’s
A chilled, dairy-free oat latte with a stated caffeine amount for its 250ml bottle.
- Sainsbury’s lists 41mg caffeine per bottle.
- Its per-100ml panel lists 4.8g sugars, equivalent to about 12g for the 250ml bottle; it contains oat.
Grind
A vanilla oat latte whose Waitrose ingredient listing specifies gluten-free oats.
- Waitrose lists 40% cold-brew coffee in the drink.
- Sugar is an ingredient, and the panel lists 4.0g sugars per 100ml. Check the current pack and availability before choosing it.
M&S Plant Kitchen
A chilled, 750ml vegan oat latte suited to portioning rather than treating the bottle as one lunch serving.
- Marks & Spencer labels this product vegan and dairy-free.
- It lists 34.6mg caffeine per 100ml and states that the drink is unsuitable for coeliacs and for people with soya or wheat allergy.
Joybuy cold brew option
This black cold brew comes in individual concentrate pouches. It suits a lunch where you can add water, rather than one that calls for a ready-to-drink bottle.

J.ZAO Extra-Strong Americano Dark Roast Cold Brew Coffee, 10 × 25ml pouches
For a black cold brew when water is available at lunch: the directions describe mixing a 25ml pouch with about 200ml water, hot or cold. The nutrition panel lists 0g sugars per 100ml, and the ingredients list water and Arabica coffee beans. Check the pack’s caffeine amount if you are limiting caffeine; the pouches are concentrate, not ready to drink as supplied.
Cold brew questions
Does “no added sugar” mean a cold brew has 0g sugars?
No. Read the total-sugars line for the amount you will drink. Sainsbury’s lists 4.8g sugars per 250ml Nolo decaf oat latte despite its no-added-sugar description, while Coffee Friend UK lists 0g per 100ml for Sandows black cold brew.
How do I compare caffeine in different bottle sizes?
Compare the caffeine in the volume you intend to drink, then account for other sources during the day. Sainsbury’s lists 41mg in a 250ml Rodd’s bottle; Coffee Friend UK lists 40.5mg per 100ml for Sandows, or about 81mg in 200ml. The NHS advises pregnant people not to exceed 200mg of caffeine a day.
Is a vegan cold brew necessarily suitable for coeliacs or people with allergies?
No. Check the exact product’s current allergen statement. Marks & Spencer labels its Plant Kitchen oat latte vegan but states that it is unsuitable for coeliacs and for people with soya or wheat allergy.
Can cold brew replace lunch?
Do not assume an ordinary cold brew is a complete lunch. Choose it as a drink alongside food; if a coffee-based product is specifically presented as a complete meal, check that product’s intended use and full nutritional information. The NHS Eatwell Guide describes food-group balance over a day or week.
Which pack format works for lunch on the go?
Choose by how you will prepare, store and portion the drink. A ready-to-drink 200ml or 250ml bottle is a single-serving format; J.ZAO’s 25ml concentrate pouches require water, while the 750ml M&S Plant Kitchen latte is a chilled multi-serve bottle.
