What should you check before buying?
Lactose-free cow’s milk
Choose it when: The guest avoids lactose but can have milk, and the dinner calls for dairy milk in cooking or drinks.
Bear in mind: It still contains milk; Arla and M&S warn that their lactose-free dairy products are not suitable for people with a milk allergy.
Dairy-free plant drink
Choose it when: Milk needs to be left out of the meal, including for a vegan guest.
Bear in mind: Plant drinks can contain other allergens, and the Food Standards Agency advises checking allergen information rather than relying on a vegan label.
Once the dietary route is clear, match the carton to the recipe, the amount you will use and when you plan to shop.
| Priority | What to check | Your needs |
| Dietary suitability |
Check whether the guest avoids lactose or milk itself. Read the exact carton’s ingredients and allergen statements; lactose-free cow’s milk still contains milk. |
I need to serve something that fits my guest’s requirements, not assume that lactose-free and dairy-free mean the same thing. |
| Recipe and coffee use |
Check the maker’s stated uses for sauces or baking. For foamed coffee, check whether the particular plant drink is intended for steaming or frothing; Oatly makes these claims for its Barista Edition. |
The drink needs to suit what I am making, whether that is a dinner recipe or coffee afterwards. |
| Milk variety |
If choosing lactose-free dairy milk, compare skimmed, semi-skimmed and whole cartons using their nutrition panels. The Waitrose listing for Arla LactoFREE whole milk states 3.6g fat per 100ml; check the exact carton for other values. |
For a recipe where the milk variety matters, I want to choose deliberately rather than treat every lactose-free carton as interchangeable. |
| Storage and quantity |
Check pack size and storage instructions before and after opening. Arla says its fresh LactoFREE semi-skimmed drink needs 0–5°C storage and is best consumed within three days of opening; follow each long-life carton’s own instructions too. |
If I am shopping ahead, I need a format I can store as directed; for one dinner, I also need to consider how much of a multipack I will use. |

Common questions
Is lactose-free cow’s milk dairy-free?
No. It is still a milk product: Arla LactoFREE semi-skimmed drink lists milk and lactase enzyme. If the dinner must be milk-free, choose a dairy-free alternative and check its own label.
Can I serve lactose-free milk to someone with a milk allergy?
Do not treat lactose-free cow’s milk as suitable for a milk allergy. Arla and M&S warn against that use, and the NHS distinguishes lactose intolerance from food allergy. Check the full allergen information of any dairy-free alternative before serving it.
Is a vegan-labelled drink automatically suitable for someone with a milk allergy?
No. The Food Standards Agency says vegan labelling is not a substitute for allergen labelling because cross-contamination can matter. Check the ingredients and precautionary allergen statement on the exact carton.
What should I choose for coffee after dinner?
If the guest can have milk but avoids lactose, Arla describes its LactoFREE semi-skimmed drink for coffee. If milk must be avoided and you want foam, look for a suitable dairy-free barista drink; Oatly describes its Barista Edition oat drink as micro-foamable and formulated not to separate in coffee. Check the chosen drink’s allergens.
How should I store lactose-free milk for the dinner?
Follow the instructions on the carton you buy. Arla says its fresh LactoFREE semi-skimmed drink should be stored at 0–5°C and is best consumed within three days of opening; do not assume every fresh or long-life product has the same instructions.
