Late-night convenience shoppers
If you want a drink without preparation, check the bottle size and storage instructions. A UHT drink may still need refrigeration once opened, while a chilled milkshake has its own storage and use-by instructions.
Who is this for?
Buyers comparing sugar labels
If a front-of-pack claim catches your eye, compare the total-sugars figures on the same basis—per 100ml or for the amount you plan to drink. “No Added Sugar” does not mean sugar-free.
Buyers looking for a dessert-style drink
If flavour and a larger chilled bottle are the draw, check how much of it you intend to drink. Tesco lists FRijj Chocolate Fudge Brownie in a 471ml bottle with 10.8g sugars per 100ml; that figure applies to this variant, not every FRijj milkshake.
What should you check?
Start with the amount you are likely to drink, then read the nutrition, ingredient and storage information for that exact pack.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar and portion | Compare total sugars per 100ml on the same basis, then check the serving size and bottle volume. Tesco lists 6.5g for Mars No Added Sugar, 8.6g for Yazoo Chocolate and 10.8g for FRijj Fudge Brownie per 100ml; these figures describe only those variants. | I want to know what is in the amount I will actually drink, rather than choosing from a flavour or front-of-pack claim alone. |
| Drink style | Check whether the pack is a UHT flavoured-milk drink or a milkshake that must be kept refrigerated. For a dairy-drink comparison, Tesco lists 3.2g protein per 100ml for Yazoo Chocolate and 3.5g for Mars No Added Sugar. | A ready-to-drink dairy drink suits me, but I may prefer either a familiar chocolate flavour or a chilled, dessert-style milkshake. |
| Ingredients | Read the current ingredient and allergen declarations for the exact variant. The Tesco listings declare milk in Yazoo, Mars and FRijj; the Mars product also lists barley and sweeteners. | If I avoid milk or barley, the exact pack declaration matters more than the drink’s name or a recipe I remember. |
| Storage | Check whether refrigeration is required before opening, after opening or both, and follow the pack’s time limit. Tesco says the named Yazoo and Mars drinks should be refrigerated after opening and consumed within three days; the named FRijj also has a use-by date to follow. | For an occasional late-night drink, I would rather buy an amount I can finish or store as instructed. |
Common buying mistakes
-
Reading “No Added Sugar” as “sugar-free”
Tesco’s Mars No Added Sugar listing also declares naturally occurring sugars. The NHS explains that total sugars on food labels include naturally occurring milk sugar, so the total-sugars figure is not a measure of free sugars alone.
Read the claim alongside the ingredient list and compare total sugars for the amount you intend to drink.
-
Comparing bottles without checking their volume
The named Yazoo and Mars drinks come in 400ml bottles, while Tesco lists FRijj Fudge Brownie in a 471ml bottle. Per-100ml figures do not describe the amount consumed if you drink the whole bottle.
Check the stated serving size and bottle volume before comparing the amount in your usual portion.
-
Overlooking milk or barley
The named dairy drinks declare milk, and the Mars product also lists barley. These declarations matter when an ingredient must be avoided.
Check the current physical pack for the exact variant if you have an allergy, intolerance or another ingredient-related dietary requirement.
-
Opening a larger bottle without a storage plan
The Tesco listings for the named Yazoo, Mars and FRijj drinks give instructions for refrigeration after opening; FRijj also needs to be used by its use-by date.
Choose a portion you can finish, or make sure you can follow the pack’s refrigeration and time instructions.
An unfinished drink may have to be discarded if you cannot store or use it within the stated limits.
Brand references
These examples describe specific listed drinks and brand ranges; check the details of the variant you are considering.
Yazoo
Tesco lists Yazoo Chocolate as a 400ml UHT flavoured-milk drink.
- The Tesco listing gives 8.6g sugars and 3.2g protein per 100ml, with two stated 200ml servings per bottle.
- It contains milk and must be refrigerated after opening. The listed nutrition applies to this chocolate bottle, not every Yazoo flavour or format.
Mars
Tesco lists a 400ml Mars chocolate, malt and caramel-flavour milk drink labelled “No Added Sugar”.
- The listing gives 6.5g total sugars and 3.5g protein per 100ml for this product.
- The drink still contains naturally occurring sugars, as well as milk, barley and sweeteners. The front-of-pack claim does not mean sugar-free.
FRijj
Müller describes FRijj as a fridge-fresh milkshake range. Tesco lists the Chocolate Fudge Brownie variant in a 471ml bottle.
- For that Fudge Brownie variant, Tesco lists 77kcal and 10.8g sugars per 100ml.
- It contains milk and requires refrigerated storage. Do not apply this variant’s nutrition figures to the rest of the range.

These ready-to-drink options include protein shakes and a yoghurt drink in different bottle or can sizes. If you want a conventional chocolate flavoured-milk drink, check each product’s description before treating it as a substitute.

LIGHT UP Zero Control Avocado Kale Chia Seed Milkshake Yoghurt Drink, 220ml

Frequently asked questions
Does “No Added Sugar” mean a milkshake contains no sugar?
No. Tesco’s listing for Mars Chocolate Flavoured Milk Drink No Added Sugar states that it contains naturally occurring sugars and gives 6.5g total sugars per 100ml. The NHS explains that total-sugars figures on labels include naturally occurring milk sugar, so read the claim alongside the nutrition and ingredient information.
Which of these named milkshakes lists the least sugar per 100ml?
Among the exact variants compared in Tesco’s listings, Mars No Added Sugar lists 6.5g total sugars per 100ml, Yazoo Chocolate 8.6g and FRijj Chocolate Fudge Brownie 10.8g. This comparison does not describe other flavours or establish each drink’s free-sugar content; check bottle size too if you plan to drink the whole pack.
Can I save an opened milkshake for another night?
Follow the instruction on the exact pack. Tesco’s listings say to refrigerate the named Yazoo and Mars drinks after opening and consume them within three days; the named FRijj must be kept refrigerated and used within three days of opening and by its use-by date.
Do these dairy drinks contain milk or barley?
Tesco’s listings declare milk in the named Yazoo, Mars and FRijj drinks, and barley in the Mars product. If you need to avoid either ingredient, read the declaration on the current pack of the exact variant rather than relying on the flavour name or an earlier purchase.
