Hosts serving guests with different tastes
If the table includes cereal, porridge or smoothies as well as hot drinks, decide whether one unsweetened carton will suit everyone or whether to offer a sweeter option too.
Who is this for?
Shoppers replacing dairy regularly
If soya drink will be more than an occasional brunch extra, compare the exact cartons for added calcium and other stated nutrients. NHS guidance includes unsweetened, calcium-fortified plant alternatives in the dairy-and-alternatives food group.
Hosts buying for a guest with an allergy
Check the guest’s specific allergies before choosing. A dairy-free or vegan description does not settle questions about milk cross-contact, and a soya drink is not suitable for someone who needs to avoid soya.
What should you check before choosing?
Start with the guests’ allergen requirements, then choose the flavour and carton format for the menu. If the drink will regularly replace dairy, compare fortification on the exact product as well.
Unsweetened and fortified
Choose when: You want an unsweetened option and added calcium is important to your choice.
Bear in mind: Check each carton; added nutrients and allergy cautions differ between products.
Original or sweetened
Choose when: Your guests prefer a sweeter drink with cereal or hot drinks.
Bear in mind: Compare the sugar information rather than assuming an original and a no-sugars variant are alike.
Organic with a short ingredient list
Choose when: Organic ingredients and a short ingredient list are your priorities.
Bear in mind: Do not assume that an organic drink has the added nutrients listed on a fortified carton.
| Priority | What to check | Your needs |
|---|---|---|
| Allergens | Read the current ingredients, declared allergens and any precautionary allergen statement. Check for soya as well as milk. | I’m serving someone with an allergy, so I need a carton that meets that guest’s particular requirements—not just a vegan claim. |
| Fortification | Look for stated calcium and, if relevant, iodine and vitamins on the exact carton. Compare unsweetened and original variants separately. | If this will regularly replace dairy, I want to know which nutrients have been added. The NHS identifies unsweetened, calcium-fortified plant alternatives as part of the dairy-and-alternatives food group. |
| Flavour and sugar | Check whether the carton is unsweetened, no sugars, original or sweetened; use its nutrition panel to compare sugars per 100ml. | I’d like a drink that suits the brunch menu, whether guests prefer an unsweetened option or a sweeter flavour. |
| Storage and serving | Check whether the carton can be stored unopened until brunch, how to refrigerate it after opening and when to use it. Follow its directions for hot drinks. | I’m shopping ahead and may have some left over, so the unopened and opened-carton instructions both matter. |
Common mistakes to avoid
-
Assuming vegan means suitable for a milk allergy
A vegan claim does not address every cross-contact risk for a guest with a milk allergy. The Food Standards Agency’s 2024 research cautions against using vegan labelling in place of allergen information.
Read the current pack’s milk-allergen information and any precautionary statement, and ask the guest what precautions they require.
-
Overlooking soya as an allergen
Removing dairy does not remove soya: soya is an ingredient in soya drinks.
If a guest needs to avoid soya, consider a different drink only after checking that product’s own ingredients and allergen information.
-
Assuming every soya drink is fortified
Fortification varies. Waitrose & Partners lists added calcium and vitamins for its Essential Unsweetened Soya Drink, while Sainsbury’s describes Plenish Organic Soya Drink as containing water and organic soybeans.
If the drink will regularly replace dairy, compare the nutrients stated on the cartons rather than relying on the words organic or plant-based.
Brand and retailer references
These examples show why the variant matters: a brand name alone does not tell you whether a soya drink is sweetened or fortified.
Alpro
Alpro has Original and No Sugars soya-drink variants listed by UK retailers.
- Waitrose & Partners lists added calcium, iodine and vitamins for Alpro’s original long-life drink.
- Original and No Sugars are distinct products; check the exact carton’s sugar and allergen information.
Tesco
Tesco Groceries lists own-label unsweetened soya drinks alongside branded options.
- An own-label unsweetened carton gives shoppers another formulation to compare.
- Check the individual product’s ingredients, fortification and allergen details rather than assuming they match a branded drink.
M&S
M&S lists unsweetened and sweetened Plant Kitchen soya drinks.
- M&S states that its Unsweetened Soya Drink is fortified with calcium, iodine, vitamin D and vitamin B12.
- Its product information includes nut and peanut allergy cautions; read the current pack for the variant you buy.
Waitrose Essential
Waitrose & Partners describes its Essential Unsweetened Soya Drink as a long-life, fortified option.
- The product page lists added calcium, vitamin D, vitamin B12, vitamin B2 and iodine.
- The manufacturer warns that this product is not suitable for children under two years old.
Plenish
Sainsbury’s lists Plenish Organic Soya Drink as a long-life drink made with water and organic soybeans.
- Its listed ingredients offer a short ingredient list for shoppers seeking one.
- Check the carton if added calcium, iodine or vitamins are important to your choice; they should not be assumed from its organic description.

Frequently asked questions
Does a vegan or dairy-free claim make a carton suitable for someone with a milk allergy?
Not automatically. The Food Standards Agency’s 2024 research cautions that vegan labelling is not a substitute for allergen information because cross-contact may still matter. Read the current pack’s milk-allergen information and any precautionary statement, and check the guest’s requirements.
Can someone with a soya allergy drink dairy-free soya milk?
No: soya drinks contain soya. If a guest needs to avoid it, check the ingredients and allergen information of a different drink before serving that instead.
Should I choose a fortified soya drink for brunch?
If the drink will regularly replace dairy, an unsweetened, calcium-fortified option is a useful starting point. The NHS includes such plant alternatives in the dairy-and-alternatives food group. Check the exact carton, since fortification varies.
Can soya drink go in tea, coffee or cooking?
Check the instructions for the carton you choose. For Waitrose Essential Unsweetened Soya Drink, Waitrose & Partners advises shaking before use, heating gently for cooking and letting hot water cool slightly before adding the drink to a hot beverage because separation can occur.
How should I store soya drink after opening?
Refrigerate it and follow the period stated on its carton; this differs by product. Waitrose & Partners instructs shoppers to keep its Essential Unsweetened Soya Drink below 5°C after opening and use it within three days.
