Who is each format for?

Decide whether the party needs sealed portions, a particular container or drinks poured into cups before comparing flavours.

Hosts handing out individual drinks

Sealed portions avoid pouring and make it easier to count one drink per guest. Ocado lists Yazoo Chocolate No Added Sugar as six individual 200ml cartons, rather than cans.

Hosts who specifically want metal cans

If cans matter to the serving plan or presentation, confirm the container on the exact product. A multipack of cartons or a single bottle does not meet a cans-only requirement.

Hosts checking guests’ allergens

Read the label of every exact pack before serving. Ocado lists milk for the Yazoo cartons, while Tesco lists milk and barley for its Mars 400ml bottle; the bottle’s declaration should not be applied to a different Mars product.

What should you check before buying?

Choose the container and serving size first, then check the drink label and your plans for chilling and opened packs.

Priority What to check Your needs
Pack format Check both the number of drinks and the container type. Ocado lists Yazoo Chocolate No Added Sugar as 6 × 200ml cartons, not cans. I want sealed drinks to hand out, but if my party plan calls for metal cans, cartons will not do the same job.
Serving size Compare the labelled volume per container with the number of guests. Ocado’s Yazoo 1L bottle is described as five servings and requires cups for sharing. Would individual portions be easier to distribute, or can I make room for cups and a bottle on the serving table?
Sugars Read the total sugars value and its basis, such as per serving or per 100ml. A no-added-sugar statement is not the same as a sugar-free declaration. I want to compare what is in the drinks, rather than choose on the front-of-pack wording alone.
Allergens Read the exact pack’s ingredients and allergen declaration. Ocado lists milk for the Yazoo cartons; Tesco lists milk and barley for its Mars 400ml bottle. If guests have food allergies, I need the label for the drink I will actually serve—not another size or format from the same brand.
Storage Check the best-before date and directions for chilling and opened packs. Ocado’s Yazoo carton and bottle listings both say to refrigerate after opening and consume within three days. I can chill drinks before guests arrive, but I also need a plan for any bottles or individual drinks opened during the party.

Common pack and label mistakes

  • Assuming every multipack contains cans

    Ocado’s Yazoo 6 × 200ml multipack contains cartons. Counting the portions without checking the container could leave a cans-only serving plan unmet.

    Check the stated package type and pack images as well as the number and size of servings before ordering.

  • Applying one Mars label to another format

    Tesco lists a Mars 400ml bottle containing milk and barley. Amazon UK’s flavoured-milk bestseller list separately names a Mars 12 × 250ml cans pack; the bottle’s ingredient declaration does not establish what is on the cans’ label.

    Read the ingredients, allergens and storage directions on the exact Mars pack you intend to serve.

  • Reading no added sugar as sugar-free

    The wording describes added sugar, not the drink’s total sugars content.

    Use the nutrition table and its stated serving size when comparing the exact products you are considering.

  • Leaving opened drinks on the serving table

    Ocado’s Yazoo carton and bottle listings and Tesco’s Mars 400ml bottle listing all direct customers to refrigerate the drink after opening and consume it within three days.

    Plan fridge space for opened drinks and follow the storage directions on each pack rather than treating an opened bottle like an unopened one.

Brand and product-line references

These examples distinguish the formats listed for each product; a brand name alone does not identify the container, ingredients or pack size.

Yazoo

Ocado lists Chocolate No Added Sugar as a 6 × 200ml carton multipack and a separate Chocolate Milkshake in a 1L bottle.

  • The carton pack provides six countable, individually sealed servings.
  • The cartons contain milk and are not metal cans. The 1L bottle requires pouring and refrigeration after opening.

Mars

Tesco lists a 400ml Chocolate Flavoured Milk Drink bottle. Amazon UK’s flavoured-milk bestseller list also names a separate 12 × 250ml cans pack.

  • The listed bottle and can formats offer different ways to serve the brand’s drinks.
  • Tesco lists milk and barley for the 400ml bottle; check the cans’ own label rather than assuming they have the same ingredients or directions.

Müller Frijj

Tesco’s milkshake category lists individual 330ml Chocolate, Strawberry Cheesecake and Fudge Brownie variants.

  • The listed 330ml drinks give hosts individual flavour options to consider.
  • An individual 330ml listing is not itself a counted multipack of cans; check the exact product format before planning quantities.

Joybuy can-format option

This selection is for hosts considering individually portioned cans. The REP option is sold as a protein shake and should be assessed as that type of drink, rather than assumed to be a conventional milkshake.

REP Vanilla Flavour protein shakes, pack of eight 250ml cans

REP Vanilla Flavour Protein Shakes, 8 × 250ml

For a party plan built around sealed cans, this eight-pack provides individual 250ml portions without pouring; it is positioned as an adult protein shake rather than a standard milkshake.

It contains milk, so check the exact pack label for guests’ allergens. The listing says to serve it chilled, refrigerate an opened can and consume it within 24 hours. Its adult-use directions also say not to exceed two cans a day unless advised by a healthcare professional.

Frequently asked questions

Are Yazoo’s 6 × 200ml drinks milkshake cans?

No. Ocado lists the Yazoo Chocolate No Added Sugar multipack as six 200ml cartons. If metal cans are essential, check the container type on the exact product rather than treating a carton multipack as interchangeable.

Can I buy unopened UHT milkshakes before the party?

Check the best-before date on the exact pack before deciding when to buy it. Ocado’s Yazoo carton and bottle listings give separate after-opening instructions: refrigerate and consume within three days.

Which allergens should I check before serving milkshakes?

Read every exact pack’s allergen declaration before serving it. Ocado lists milk for the Yazoo cartons, and Tesco lists milk and barley for its Mars 400ml bottle; those details should not be transferred to a different product or format.

Does no added sugar mean a milkshake is sugar-free?

No. No added sugar does not mean the drink contains no sugars. If that distinction matters to your choice, compare the total sugars stated per serving or per 100ml on the exact pack.
