Costco UK lists Mars Chocolate Milk Drink in 12 x 250ml cans, but its advice to serve them chilled does not establish whether unopened cans can be kept in a cupboard. Check the exact case’s storage instructions and best-before date before buying it for pantry stocking. If cans are optional, Tesco’s Yazoo 6 x 200ml UHT carton pack provides smaller individual portions in a different format.
A case keeps portions separate, but the can format alone does not settle whether the drinks belong in a cupboard. For the Mars 12-can case listed by Costco UK, check the unopened storage wording and printed date before planning where to keep it.
If cans are not essential, Tesco lists Yazoo No Added Sugar Chocolate Milk Drink as six 200ml UHT cartons. Compare that portion size with a 250ml can, and check the exact pack’s ingredients if the recipe matters to you.
Pack format and brand name do not replace the ingredient list. Compare sugars per 100ml, the stated serving size, sweeteners and allergens on the drink you intend to buy, rather than using details from another bottle, carton or can.
Start with the unopened storage instructions: a multipack only serves a pantry stock-up if its label fits your storage plan and the portions can be used by the printed date. Then compare formats and recipes on the exact packs.
| Priority | What to check | Your needs |
|---|---|---|
| Unopened storage | Read the exact pack’s unopened storage instructions and best-before date. Costco UK describes the Mars 12 x 250ml cans as best served chilled; serving advice is not a cupboard-storage instruction. | I’m stocking a cupboard, so I need the case label to confirm that my intended storage conditions are suitable and that I can use the portions by their printed date. |
| Pack and portion size | Compare count, volume per container and total volume: Mars is listed as 12 x 250ml cans; Tesco’s Yazoo multipack is 6 x 200ml cartons. Check whether a larger bottle would suit shared servings instead. | Separate portions matter to me more than a bottle I would need to divide. If I prefer a smaller serving, the 200ml carton is worth considering even though it is not a can. |
| Sugars and ingredients | Compare sugars per 100ml and per serving, and read the ingredients for sweeteners. A no-added-sugar claim is not the same as a sugar-free claim. | I want to compare the drinks I would actually serve, without assuming that their front-of-pack claims or different portion sizes mean the same thing. |
| Allergens | Check the exact product’s ingredients list for milk and any other relevant allergens. The Food Standards Agency says allergens in prepacked food must be emphasised in that list. | If an ingredient matters to my household, I need the label for this variant and pack format—not the recipe of another drink from the same brand. |
“Best served chilled” on Costco UK’s Mars case listing describes serving, not the conditions for storing unopened cans. A 12-can purchase may not fit a planned pantry stock-up unless those conditions are clear.
Read the exact case or can for unopened storage instructions and its best-before date. Do not transfer UHT or storage wording from a different bottle or carton.
Mars 12 x 250ml cans and Yazoo 6 x 200ml cartons differ in both container size and pack count. A pack-level comparison alone can obscure how many separate servings you are buying.
Compare the number of containers, millilitres per container and total litres, alongside the date and storage wording on each pack.
A no-added-sugar claim does not tell you the drink has no sugars. It also does not identify every ingredient in the recipe.
Use the exact pack’s nutrition panel to compare sugars per 100ml and per serving, then check its ingredient list for sweeteners and allergens.
The reviewed Mars bottle, Yazoo cartons and Frijj bottle are distinct products and pack formats. Instructions for an opened bottle cannot establish how to store an unopened case of cans.
Check the ingredients, nutrition information and storage instructions on the format and variant you will buy.
These examples show why a brand name alone is not enough to identify the format or storage instructions you need.

No. Costco UK identifies its Mars Chocolate Milk Drink case as 12 x 250ml cans and says it is best served chilled, but that serving advice does not establish unopened storage conditions. Check the actual case’s storage wording and best-before date before using it for pantry stocking.
No. A drink with no added sugar can still contain sugars. Compare the sugars figures per 100ml and per serving on the exact pack, and read its ingredients if sweeteners matter to your choice.
Read the ingredients list on the exact prepacked drink before buying it. The UK Food Standards Agency says allergens present in prepacked food must be emphasised in that list; do not assume another flavour or pack format has an identical recipe.
