For regular afternoon tea, an unsweetened soya drink labelled suitable for vegans is a starting point; check the carton for calcium, vitamin D, vitamin B12 and iodine rather than assuming every soya drink has the same fortification. A long-life UHT carton suits occasional hosting before it is opened, but still needs refrigeration afterwards. Follow the carton’s hot-drink directions to reduce separation, and check allergens with each guest before serving.
The right carton depends on whether the drink is for everyday tea, occasional visitors or guests with particular ingredient requirements.
A regular soya drink can be compared for its stated protein and fortification as well as its flavour in tea. The NHS recommends including fortified dairy alternatives in a vegan diet; a drink is one part of that diet, not a complete substitute for varied food.
Check vegan suitability, the current allergen information and any directions for adding the drink to hot tea. An unopened UHT carton can be useful to keep for an occasional visit, provided its storage instructions suit your plans.
Compare unsweetened and original varieties per 100ml, then check their fortification separately. A lower sugar figure does not establish that two cartons contain the same added nutrients.
Start with suitability and the nutrition label, then consider how the drink will be served and stored.
| Priority | What to check | Your needs |
|---|---|---|
| Vegan suitability and fortification | Look for an explicit vegan-suitability statement. Read the current label for calcium, vitamin D, vitamin B12 and iodine individually; the NHS recommends fortified dairy alternatives for vegan diets. | I want a drink suitable for a vegan guest and need to know which added nutrients this particular carton lists. |
| Sugar and flavour | Compare sugars per 100ml on unsweetened and original cartons. Check fortification too, rather than treating the flavour choice as a nutritional comparison. | For everyday tea, I would prefer a less sweet drink; for a guest who prefers a sweeter flavour, I can compare an original variety. |
| Hot-tea preparation | Read the carton’s hot-drink instructions. Tesco advises adding its soya drink before the hot liquid and not mixing it with boiling water; Sainsbury’s advises allowing water to cool slightly. | I want to serve tea without the drink visibly separating, so I can follow the directions for the carton I choose. |
| Storage after opening | Check whether the carton is UHT and how to store it before opening. Compare its refrigeration instructions and stated use period after opening. | Visitors come occasionally, so cupboard storage before opening helps; afterwards, I need a carton size we can use within its labelled period. |
| Guest allergens | Check ingredients, highlighted allergens and relevant precautionary information on the current pack. A vegan statement does not establish suitability for someone with a food allergy. | I need to ask guests about allergies before serving. In a Food Standards Agency and Ipsos UK online survey in England, Wales and Northern Ireland on 15–20 December 2023, 53% of respondents with hypersensitivity to animal-origin allergens were already aware that vegan products might be unsuitable because of cross-contamination. |
Fortification varies between plant-based drinks. The UK SACN and COT assessment also notes that products labelled organic in the UK are not allowed to be fortified with nutrients.
If the drink will regularly replace dairy milk, compare its label for calcium, vitamin D, vitamin B12 and iodine rather than relying on the words ‘vegan’ or ‘soya’.
The drink may visibly separate, changing how the tea looks when served.
Follow the chosen carton’s method. That may mean adding the soya drink before the hot liquid or allowing the water to cool slightly.
Soya itself is an allergen. Vegan products may also be unsuitable for a guest with another relevant allergy; the cited M&S unsweetened drink carries nut- and peanut-allergy unsuitability information.
Ask guests about allergies and check the ingredients and precautionary information on the carton you will serve.
UHT storage applies before opening. The cited Waitrose Essential carton states three days after opening, while the cited Tesco and Alpro long-life cartons state five days; follow the current pack for the product you buy.
Choose a carton size you expect to use within its refrigerated use period, and mark the opening date if several people share it.
A larger carton may leave unused drink when tea is served only occasionally.
These examples show why it is worth comparing specific varieties rather than assuming every product from a brand has the same sugar level or fortification.
Alpro lists Original and No Sugars soya drinks. Its Original product information lists calcium and vitamins D and B12; the cited long-life No Sugar listing also names iodine.
Tesco lists chilled and long-life unsweetened soya drinks with added calcium, iodine, vitamin B12, riboflavin and vitamin D2.
The cited unsweetened soya drink lists calcium, vitamin D, vitamin B12 and iodine.
The cited Essential Unsweetened Soya Drink is UHT and lists added calcium, vitamin D, vitamin B12, vitamin B2 and iodine.
The cited unsweetened soya drink lists calcium, iodine, vitamin D and vitamin B12 fortification.
This option is an unsweetened, long-life soya-drink multipack for someone who wants unopened cartons available for vegan afternoon tea.

This vegan-suitable UHT drink comes as eight 1L cartons for unopened cupboard storage. The listing states 0.0g sugars and 3.3g protein per 100ml and lists calcium and vitamins D and B12. If iodine matters to your choice, check the current carton; check it also for hot-tea directions. After opening, refrigerate at +1°C to +7°C and use within five days.
Check the current carton for vegan suitability and its listed fortification. The NHS recommends fortified dairy alternatives for vegan diets; compare calcium, vitamin D, vitamin B12 and iodine on the individual product label rather than assuming they are all present.
Choose according to the guest’s flavour preference and compare sugars per 100ml. An unsweetened variety suits someone who prefers less sugar, while an original variety may suit someone who wants a sweeter drink; check each carton’s fortification separately.
Follow the directions on the carton you are serving. Tesco advises adding its soya drink before the hot liquid and not mixing it with boiling water; Sainsbury’s and Waitrose advise letting the water cool slightly.
An unopened UHT carton can be stored as its pack directs, but refrigerate it after opening. The cited Tesco and Alpro long-life products state five days after opening, while the cited Waitrose Essential carton states three days; use the period printed on your carton.
No. Soya is an allergen, and vegan labelling does not replace an ingredients or precautionary-allergen check. Ask guests about their allergies and read the current carton before serving it.
