Black-coffee drinkers checking sugars
Tesco Finest concentrate lists 0 g sugars per prepared 200 ml glass but needs diluting. A Coffee Friend UK listing describes Sandows as a ready-to-drink, dairy-free black coffee with 0 g sugars per 100 ml.
Who is each option for?
For a desk lunch, the useful distinction is whether you want black coffee, an oat latte or a milk coffee—and whether you can prepare a concentrate.
Shoppers looking for a dairy-free latte
M&S describes its Oat Latte Cold Brew Coffee as dairy-free. It also states that this product is not suitable for coeliacs or people with a wheat allergy, so those requirements need a separate check.
Milk-coffee drinkers avoiding added sugar
Emmi Caffè Latte Zero offers lactose-free milk coffee labelled no added sugar. Tesco Groceries lists 9.2 g sugars and 125 mg caffeine per 230 ml cup; it contains milk and is not a sugar-free option.
What should you check before choosing?
Start with the drink format and dietary requirements, then compare sugars for the amount you will drink. A concentrate’s figures and instructions may describe a different serving from a ready-to-drink pack.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Read the sugars line alongside any unsweetened or no-added-sugar claim. Tesco Groceries lists 0 g per prepared 200 ml glass for Tesco Finest concentrate; its Emmi listing gives 9.2 g per 230 ml cup despite the no-added-sugar label. | I want to know the sugars in the serving I will drink, rather than rely on wording on the front of the pack. |
| Ingredients and allergens | Check milk, oat and wheat information separately. M&S says its dairy-free Oat Latte is not suitable for coeliacs or people with a wheat allergy; Emmi’s lactose-free coffee still contains milk. | A dairy-free or lactose-free label needs to match my particular requirement; the two terms are not interchangeable. |
| Caffeine | Look for an amount per cup or bottle, not just per 100 ml. Tesco Groceries lists 125 mg per 230 ml Emmi cup; Coffee Friend UK lists 40.5 mg per 100 ml for Sandows. | If I also drink coffee or tea later, I want to account for the caffeine in my lunch drink. |
| Preparation and storage | Check whether the coffee needs diluting and how long it keeps after opening. Tesco Finest uses 100 ml concentrate and 100 ml cold water and has a four-week refrigerated opened-life; Tesco lists seven days after opening for Grind concentrate. | With no glass or water at my desk, I would choose a ready-to-drink pack. For a concentrate, I need to be able to store and use it as instructed. |
What is easy to overlook?

Reading ‘no added sugar’ as ‘zero sugar’
A milk coffee can have sugars on its nutrition panel without added sugar. Tesco Groceries lists 9.2 g sugars per 230 ml cup for Emmi Caffè Latte Zero.
Compare sugars for the whole serving and check the ingredients, rather than using the front-of-pack claim alone.

Assuming dairy-free oat coffee meets every allergen requirement
M&S describes its Oat Latte Cold Brew Coffee as dairy-free but says it is not suitable for coeliacs or people with a wheat allergy.
Check the current pack for the specific ingredients and allergen information you need.
-
Buying concentrate without planning to mix or store it
Concentrate needs preparation at the desk. Tesco Finest also requires refrigeration after opening and use within four weeks; Tesco gives Grind concentrate a seven-day opened-life.
Check that you will have water and a glass, and that you can use the carton within its stated opened-life.
An unfinished carton may go to waste if it cannot be used within that period.

Overlooking caffeine in a chilled lunch drink
Tesco Groceries lists 125 mg caffeine per Emmi cup, while Coffee Friend UK lists 40.5 mg per 100 ml for Sandows. Other drinks during the day also contribute to your caffeine intake.
Check the amount for the pack you plan to drink and consider it alongside your other caffeine-containing drinks.

Cold-brew questions
Does ‘no added sugar’ mean a cold-brew latte is sugar-free?
No. Tesco Groceries lists Emmi Caffè Latte Zero as no added sugar, but its nutrition panel gives 9.2 g sugars per 230 ml cup. Check the sugars figure for the whole pack.
What can I choose for vegan black coffee with 0 g listed sugars?
Tesco Groceries lists its Finest Unsweetened Cold Brew Coffee Concentrate as suitable for vegans, with 0 g sugars per prepared 200 ml glass; you need to dilute it. For a ready-to-drink alternative, Coffee Friend UK lists Sandows black cold brew as dairy-free, with 0 g sugars per 100 ml. Check the current pack against your requirements.
Is an oat cold-brew latte suitable for coeliacs?
Not necessarily. M&S explicitly says its dairy-free Oat Latte Cold Brew Coffee is not suitable for coeliacs or people with a wheat allergy. Check the allergen information for the particular drink rather than relying on ‘oat’ or ‘dairy-free’.
How do I compare caffeine in lunch-size cold coffees?
Compare the amount in the portion you will drink. Tesco Groceries lists 125 mg per 230 ml Emmi cup; Coffee Friend UK lists 40.5 mg per 100 ml for Sandows, which is about 81 mg in its 200 ml bottle. Account for other caffeine-containing drinks during the day too.
What should I check on a chilled coffee pack?
Check the ingredients and allergens against your requirements, then read sugars for the serving you will drink. Follow the pack’s storage and preparation instructions, and check any caffeine or sweetener information relevant to your choice.
