What should you check before buying?
Decide whether guests will mix their own drinks or take a ready-made shake, then check where the unopened packs and opened drinks will go.
Filtered fresh milk
Choose when: You want to blend flavours or portions near serving time and can keep the milk chilled.
Plan for: A chilled ingredient and preparation at the party; filtering alone does not establish unopened cupboard storage.
UHT milk base
Choose when: You want to make the shakes yourself but need an explicitly long-life base before the event.
Plan for: Flavour ingredients, mixing equipment and the carton’s storage instructions after opening.
Ready-to-drink shakes
Choose when: You want to avoid blending drinks and the selected unopened pack is labelled for ambient storage.
Plan for: Fridge space after opening and a check of each flavour’s ingredients and pack size.
| Priority | What to check | Your needs |
| Unopened storage |
Read the selected pack’s storage wording and date. Tesco distinguishes filtered fresh milk from UHT long-life milk; Yazoo says its flavoured milk can be kept in a cupboard until opened. |
I want to buy drinks ahead, but fridge space is limited until the party. |
| Serving and chilling |
Check the instructions after opening and how much can be chilled between pours. The reviewed ASDA FRijj 950ml and Tesco Mars 400ml drinks say to refrigerate after opening and consume within 3 days. |
Guests may help themselves over several hours, so I need a way to keep opened bottles cold rather than leaving them on the table. |
| Ingredients and allergens |
Keep the label for each flavour and check its ingredient and allergen statements. Tesco lists milk and barley for the reviewed Mars drink; its Arla Lactofree dairy drink is labelled unsuitable for people with a milk allergy. |
Some guests need to check what is in their drink. I cannot use “lactose-free” as a substitute for checking milk-allergy suitability. |
| Pack and nutrition details |
Compare the stated pack sizes with how you intend to pour drinks. Read the full nutrition panel: the reviewed 400ml Mars drink’s “no added sugar” claim does not mean sugar-free. |
A shared bottle may work for refills, while smaller packs make it easier to plan individual drinks. I also want guests to be able to check the exact flavour’s label. |

Questions about serving milkshakes
Does filtered milk mean long-life milk?
No. Tesco lists filtered fresh milk separately from UHT long-life milk. If you need unopened cupboard storage, check the exact pack for UHT or long-life labelling and its storage instructions.
Can I keep unopened ready-to-drink shakes in a cupboard?
Some selected products allow it: Yazoo says its flavoured milk is long life, while ASDA describes the reviewed FRijj 950ml drink as ambient-stored before opening. Check the individual pack rather than assuming every flavour or format has the same instructions.
What should I do with a shared bottle after opening it?
Refrigerate it if the pack instructs you to do so, and follow its stated use-by-opening period. Yazoo’s guidance and the reviewed FRijj and Mars product information each say to refrigerate after opening and consume within 3 days; keep an opened party bottle cold between pours.
Is lactose-free filtered dairy milk suitable for a milk allergy?
Do not assume so. Tesco’s listing for Arla Lactofree UHT filtered milk explicitly says it is unsuitable for people with a milk allergy. Confirm what the guest must avoid and check the exact product’s ingredient and allergen information.
Should I keep the packaging at a community Halloween event?
Yes, it lets guests check the ingredients in the drinks you serve. GOV.UK guidance for community and charity events in England, Northern Ireland and Wales recommends keeping prepacked-food packaging so people with food hypersensitivities can inspect it.
