Self-catering holiday households
Sealed cartons can be useful when fridge space is limited before use. You still need room to chill each opened carton and a plan to finish it within the period on its label.
Who is this choice for?
Vegan shoppers comparing fortified drinks
If you are choosing a dairy alternative as part of a vegan diet, check the exact carton for calcium, iodine, vitamin D and B12 rather than assuming every soya drink has the same fortification. The NHS advises choosing fortified dairy alternatives and checking plant drinks for iodine.
Shoppers comparing sugars
For cereal, hot drinks or cooking on holiday, compare unsweetened, no-sugar and original cartons using their nutrition panels. A flavour name alone does not tell you the sugars figure.
What should you check before buying?
Start with storage and carton size for the trip, then compare the nutrition and ingredient labels for everyone who will use the drink.
| Priority | What to check | Your needs |
|---|---|---|
| Storage | Check the unopened storage instructions and whether the carton is labelled long life or UHT. Read its refrigeration and use-up instructions for after opening. | I need to keep sealed drinks in a cool, dry place, but I can make room in the fridge once I open one. |
| Carton size | Compare the number and size of cartons with expected use. Check whether an opened carton can be finished within its stated period. | For a short stay or a small group, I would rather open a carton when it is needed than leave a large one unfinished. |
| Sugars | Compare sugars on the nutrition panels using the same measurement basis, such as per 100ml. Check the exact variant rather than applying one carton’s figures to a whole range. | Lower sugar matters to me, so I want to compare an unsweetened or no-sugar carton with the original version. |
| Fortification | Check the carton for the nutrients relevant to your choice, including calcium, iodine, vitamin D and B12. The NHS notes that only some plant drinks are fortified with iodine. | When I use soya drink as a dairy alternative in a vegan diet, I want to know what the particular carton contains. |
| Ingredients and age guidance | Read the ingredient and allergen declaration; the Food Standards Agency identifies soya as an allergen. If buying for a young child, check the product’s age guidance rather than assuming an adult drink is suitable as their main milk alternative. | Someone in my household has a soya allergy, or I am choosing a drink for a young child, so the exact label matters. |
Common buying mistakes
-
Assuming “long life” applies after opening
The long-life storage instructions apply to sealed cartons. Marks & Spencer and Sainsbury's list three days after opening for the cited cartons; Waitrose lists five days for its cited Alpro carton, with refrigeration required in each case.
Open one carton at a time and follow its own refrigeration and use-up instructions.
An opened carton also takes up fridge space during the trip.
-
Assuming all soya drinks have the same fortification
Fortification varies by product. The NHS advises choosing fortified dairy alternatives for a vegan diet and says only some plant drinks are fortified with iodine.
Check the exact carton for the nutrients that matter to your choice, rather than relying on the brand or the words “soya drink”.
-
Choosing by flavour name instead of the sugars figure
Original, unsweetened and no-sugar variants are distinct products; their names do not replace a comparison of nutrition panels.
If sugars are a deciding factor, compare the exact variants on the same per-100ml basis where the labels allow it.
Brand and own-label references
These examples illustrate label details worth comparing; a brand name does not establish the storage or nutrition of every carton in its range.
Alpro
Its cited long-life soya drinks include original and no-sugar variants. Sainsbury's and Waitrose list added nutrients for the respective products.
- The cited Alpro Original listing names added calcium, iodine and vitamins B2, B12 and D2.
- Waitrose instructs shoppers to refrigerate its cited long-life Alpro carton after opening and use it within five days.
Sainsbury's
Its Unsweetened Long Life Soya Drink is a 1-litre own-label option.
- The product is identified as unsweetened and long life in Sainsbury's listing.
- Sainsbury's instructs shoppers to refrigerate it after opening and use it within three days.
M&S Plant Kitchen
Marks & Spencer lists soya drinks for shoppers comparing unsweetened and other variants.
- Its Plant Kitchen Soya Drink listing states that calcium, iodine and vitamins D and B12 have been added.
- The cited Unsweetened Soya Drink must be refrigerated at 0°C to 5°C after opening and consumed within three days.
Waitrose Essential
Waitrose lists an Essential Unsweetened Soya Drink as a 1-litre long-life carton.
- The listed carton offers an own-label unsweetened format for comparison.
- Check that carton’s nutrition, allergens and post-opening instructions before choosing it for the trip.

Vita Low-Sugar Soy Milk, 6 × 250ml

Questions about holiday soya drinks
Can long-life soya drink stay outside the fridge on holiday?
A sealed carton can be stored outside the fridge when its label permits cool, dry or ambient storage. Once opened, follow its refrigeration instructions: the cited Marks & Spencer and Sainsbury's cartons specify use within three days, while Waitrose specifies five days for its cited Alpro carton.
How many cartons should I take?
Base the number on expected use, carton size and how quickly your group can finish each opened carton. Check the product’s post-opening period and make sure you have fridge space before opening another one.
What should I check if I want a fortified soya drink?
Read the exact carton for the nutrients you want to compare, including calcium, iodine, vitamin D and B12. The NHS advises fortified dairy alternatives for a vegan diet and notes that iodine is added to only some plant drinks.
Can someone with a soya allergy drink soya milk?
No: soya drink contains the allergen relevant to a soya allergy. The Food Standards Agency identifies soya as an allergen; check each product’s ingredients and allergy declaration when choosing drinks for the household.
