Households sharing a TV dinner
A 1L bottle offers several pours from one pack. Tesco Groceries lists 1L Yazoo milkshakes; check the chosen bottle’s instructions if some will be left for later.
Who is each format for?
The number of diners matters as much as the size of the pack: a shared bottle and a multipack of individual drinks serve different needs.
Shoppers comparing protein-enriched drinks
Check the stated amount per serving, not just the word “protein” on the front. Tesco Groceries lists 57g protein per litre for Arla Protein Chocolate and 75g per 1L carton for Pro Mlk Chocolate.
People buying for one
An individual bottle gives one diner a defined portion without opening a 1L pack. Tesco Groceries lists Müller Frijj Chocolate in 330ml and Mars No Added Sugar chocolate-flavoured milk drink in 400ml.
What should you check?
Start with how many servings you need, then compare the exact drinks on their labels for nutrition, allergens and storage.
| Priority | What to check | Your needs |
|---|---|---|
| Pack size | Compare the pack volume and stated servings. A 1L bottle can be poured for several diners; individual bottles provide separate portions. | Are several people having a drink, or do I only need one bottle? I also need to know whether any remainder will be used within the pack’s instructions. |
| Nutrition label | Compare sugars and protein on the same per-100ml or per-serving basis. Yazoo lists 8.7g sugars and 3g protein per 100ml for Banana; Tesco Groceries lists 57g protein per litre for Arla Protein Chocolate and 75g per carton for Pro Mlk Chocolate. | If I want a protein-enriched drink, I’ll compare the amount in the portion I expect to pour. For a “no added sugar” product, I’ll still read its sugars figure. |
| Milk allergen | Read the ingredients and allergen declaration on the exact flavour. The Food Standards Agency identifies milk as an allergen; a “lactose free” description does not answer a milk-allergy question. | If someone drinking it has a milk allergy, I need a product whose allergen information confirms it is suitable, rather than choosing by flavour or format. |
| Storage | Check the use-by date, refrigeration instructions and time allowed after opening. Tesco Groceries says the Arla Protein carton should be refrigerated after opening and consumed within three days; Pro Mlk specifies 0–5°C storage and use within three days of opening and by its use-by date. | Will I be able to keep an opened carton chilled and finish it within its stated period? If not, separate bottles may be simpler to portion out. |
Common buying mistakes
-
Choosing the largest pack without planning for leftovers
A 1L drink gives several servings, but an unfinished pack must still be stored and used according to its label.
Decide how many people will drink it, then check the opened-pack instructions before choosing between one large bottle and individual portions.
-
Reading “protein” or “no added sugar” as an allergen answer
Those descriptions do not establish that a milk-based drink is suitable for someone with a milk allergy. “No added sugar” also does not mean the nutrition label will show zero sugars.
Check the exact product’s milk allergen declaration, ingredients and nutrition panel before buying.
-
Overlooking storage instructions after opening
Opened-pack instructions differ between drinks. Tesco Groceries states a three-day refrigerated period for Arla Protein and a three-day limit, subject to the use-by date, for Pro Mlk.
Follow the chosen pack’s temperature and timing instructions. GOV.UK explains that a use-by date concerns food safety, while a best-before date concerns quality.
Relevant brand references
These examples show how pack formats and label details differ; they do not indicate which brands are available in the Joybuy products below.
Yazoo
Tesco Groceries lists Yazoo milkshakes in 1L bottles, a format to consider when several diners want a pour from one pack.
- The 1L format allows several servings from one bottle.
- Yazoo lists milk in its Banana drink; its stated sugars are 8.7g per 100ml. Check the label for the flavour you choose.
Müller Frijj
Tesco Groceries lists Müller Frijj Chocolate in a 330ml bottle for an individual serving.
- The separate bottle avoids opening a multi-serve pack for one diner.
- Check the chosen bottle’s nutrition and allergen label rather than assuming details are the same across flavours.
Mars
Tesco Groceries lists a 400ml Mars chocolate-flavoured milk drink labelled No Added Sugar.
- The 400ml bottle is a separate portion rather than a shared 1L pack.
- “No added sugar” does not mean sugar-free; check the sugars figure, ingredients and milk allergen declaration on the bottle.
Arla Protein
Tesco Groceries lists Arla Protein Chocolate as a 1L milkshake with 57g stated protein per litre.
- The carton is described as three 330ml servings, each with 19g stated protein.
- It is milk-based. After opening, Tesco Groceries instructs shoppers to refrigerate it and consume it within three days.
Pro Mlk
Tesco Groceries lists Pro Mlk Chocolate in a 1L carton labelled with 75g protein per carton and No Added Sugar.
- The carton is described as three servings for shoppers comparing stated protein amounts.
- It is milk-based and requires 0–5°C chilled storage; once opened, use it within three days and by its use-by date.

Questions about choosing and storage
Is a 1L milkshake enough for a TV dinner for two?
It can provide a drink for two if both want a portion, though the amount each person pours will determine what remains. Tesco Groceries describes its 1L Arla Protein and Pro Mlk cartons as about three servings; check the chosen product’s instructions for storing any remainder.
How should I store a large milkshake after opening?
Follow the instructions on that pack. Tesco Groceries says to refrigerate Arla Protein after opening and consume it within three days; Pro Mlk specifies storage at 0–5°C and use within three days of opening and by its use-by date. GOV.UK advises keeping food at 5°C or below when its label requires refrigeration after opening.
Are the Yazoo, Arla Protein and Pro Mlk examples suitable for someone with a milk allergy?
No: the checked drinks are milk-based, so someone with a milk allergy should not choose them as an alternative to a milk-free drink. The Food Standards Agency identifies milk as an allergen; always check the exact product’s allergen declaration.
Does “no added sugar” mean a milkshake contains no sugar?
No. A no-added-sugar claim does not tell you that the sugars figure is zero. Read the nutrition panel for the exact flavour and compare figures on the same per-100ml or per-serving basis.
Can I drink a milkshake after its use-by date?
Do not use a milkshake past its use-by date. GOV.UK explains that use-by dates concern food safety, rather than simply a change in quality; follow the pack’s storage instructions as well.
