Shoppers comparing sugar
If you want a flavoured milk drink for a regular break, compare the total sugars per 100ml as well as any no-added-sugar wording. The size you intend to drink matters too.
Who is choosing a revision snack?
Students choosing a flavour-led break
Chocolate, caramel and fudge brownie flavours may appeal when the drink is an occasional snack. Keep water available rather than relying on a dessert-style milkshake as your only drink during revision.
Households planning several servings
Multipack cartons provide separate portions, while a larger bottle needs a plan for serving and storage. For example, Sainsbury's lists five 200ml servings for Yazoo Strawberry 1L and says to refrigerate it after opening and use it within three days.
What should you check?
Start with the drink's role in your revision break, then compare its sugar information, pack size and ingredients.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar wording | Compare total sugars per 100ml, then consider the amount you will drink. No added sugar does not mean sugar-free: Yazoo lists 4.7g per 100ml for Kids Chocolate and 8.6g per 100ml for its standard Chocolate drink. | I want to tell a no-added-sugar carton from a standard sweetened drink without assuming either has no sugar. |
| Drink or snack | Decide whether the milkshake is a planned snack or your drink for a long session. The NHS describes water as a hydration choice, and King's College London recommends water during exam preparation. | A flavoured drink sounds appealing for a break, but I also want water within reach while I revise. |
| Serving and storage | Check the carton or bottle volume and any instructions after opening. Sainsbury's lists five 200ml servings for Yazoo Strawberry 1L, with refrigeration and use within three days after opening. | For one break, I would rather choose a defined portion; a larger bottle makes sense only if we will use its servings in time. |
| Ingredients | Read the current ingredients and allergen label for the exact drink. GOV.UK says prepacked food and drink must clearly identify any of the 14 regulated allergens present as ingredients. | If milk or another ingredient is a concern in my household, I need to check the particular pack rather than rely on an older online description. |
Common buying mistakes
-
Reading 'no added sugar' as 'sugar-free'
Naturally occurring milk sugars can remain. Yazoo lists 4.7g sugars per 100ml for Kids Chocolate despite its no-added-sugar wording.
Compare total sugars on the nutrition panel per 100ml, then check how much of the carton or bottle you expect to drink.
-
Using a dessert-style milkshake as the only drink
A flavour-led snack serves a different purpose from keeping a drink at your desk throughout revision. The NHS identifies water as a hydration choice; Sainsbury's lists 10.9g sugars per 100ml for Müller Frijj Fudge Brownie.
Keep water available and, if you want the milkshake, make it a separate snack break.
-
Opening a large bottle without planning the servings
Sainsbury's lists five 200ml servings for Yazoo Strawberry 1L and instructs shoppers to refrigerate it after opening and use it within three days.
Choose a smaller pack for a single break, or check that you can store and use the larger bottle as directed.
-
Relying on an old ingredients listing
Ingredients and allergen information can change. For a dairy milkshake, the exact product's current label matters if milk or another ingredient needs to be avoided.
Read the ingredients and highlighted allergens on the pack before choosing it.
Brand and retailer references
Yazoo
Yazoo offers standard flavoured milk, no-added-sugar Kids drinks and an indulgent milkshake range. Compare the exact variety rather than treating them as nutritionally interchangeable.
- Yazoo lists 4.7g sugars per 100ml for Kids Chocolate and 8.6g per 100ml for standard Chocolate.
- Flavour, formulation and pack size differ across the range; check the product you intend to buy.
Müller Frijj
The Fudge Brownie milkshake is a dessert-style option sold in a 330ml bottle in the Sainsbury's listing.
- Sainsbury's lists 10.9g sugars per 100ml, so shoppers can compare it with other drinks on the same volume basis.
- Consider the full bottle size when deciding whether it fits the snack break you have planned.
Mars
Tesco lists a 400ml chocolate, malt and caramel flavour Mars milk drink with sweeteners and no-added-sugar wording.
- The listing also states that the drink contains naturally occurring sugars.
- Check the current nutrition panel before comparing its total sugars with another no-added-sugar drink.
Tesco
Tesco's ready-to-drink milkshake listings provide examples of 200ml cartons, 330ml and 400ml bottles, and 1L bottles. It is a retailer reference, not a single milkshake brand.
- The different pack formats make it useful to compare the serving you intend to drink.
- Tesco advises shoppers to read current product labels because ingredients, nutrition and allergens can change.

Frequently asked questions
Should a milkshake replace water during a long revision session?
Keep water available throughout the session and treat a milkshake as a separate snack or break-time drink. The NHS describes water as a hydration choice, while King's College London recommends it during exam preparation.
Does no added sugar mean a milkshake is sugar-free?
No. Yazoo states that its no-added-sugar Kids Chocolate drink contains naturally occurring sugars, and Tesco says the same of its Mars milk drink. Compare total sugars per 100ml and the serving you expect to drink.
What should I check if someone has a milk allergy?
Check the ingredients and highlighted allergens on the exact current pack; do not assume a standard dairy milkshake is suitable. GOV.UK says prepacked food and drink must clearly identify regulated allergens present as ingredients.
How long can I keep an opened milkshake bottle?
Follow the instructions on that bottle. Sainsbury's listings for Yazoo Strawberry 1L and Müller Frijj Fudge Brownie both specify refrigeration after opening and use within three days, but that timing should not be assumed for other drinks.
