Bakers following a biscuit recipe
If the recipe already sets the sugar and liquid quantities, check the drink’s ingredients and sugars line before substituting it for dairy milk.
Who is this choice for?
Households keeping a carton for occasional baking
A long-life carton can be kept unopened in the cupboard. Once opened, it needs refrigeration and must be used within the period stated on its pack.
Bakers checking allergens
Soya is an allergen, and some products carry additional suitability warnings. Read the current carton before baking for anyone with an allergy.
What should you check?
Start with the recipe’s sweetness, then check storage instructions and any preparation or allergen information that affects your baking.
| Priority | What to check | Your needs |
|---|---|---|
| Recipe sweetness | Read both the ingredients and sugars per 100 ml. Tesco Groceries lists 0.5 g sugars per 100 ml for its unsweetened long-life drink and 2.5 g per 100 ml, with sugar in the ingredients, for its sweetened version. | I want the sugar measured into my biscuit recipe to remain the main source of sweetness, rather than adding a sweetened drink without adjusting the recipe. |
| Opened-carton storage | Check the exact pack’s refrigeration instructions and use-within period. Tesco Groceries specifies 5 days after opening for its Sweetened drink; Waitrose & Partners specifies 3 days for Essential Unsweetened. | For occasional baking, I need a plan for using the rest of an opened carton within its stated period. |
| Heating | If the preparation involves warming the drink, follow its cooking instructions. Waitrose & Partners advises heating its Essential Unsweetened drink gently and removing it from the heat before it boils. | I may warm the drink during preparation and want to follow the carton’s guidance rather than assume every soya drink handles heating the same way. |
| Allergens | Read the current ingredients, allergen emphasis and suitability warnings. M&S identifies soya in its Unsweetened Soya Drink and states that it is not suitable for people with a nut allergy. | Everyone eating the biscuits needs to be able to have the ingredients in this particular carton, not just avoid dairy. |
| “Filtered” wording | Look for a product-specific explanation of what “filtered” means and any biscuit-baking guidance. UHT or long-life wording describes the storage format, not a demonstrated filtering benefit in biscuits. | If filtering matters to my choice, I need to know what the maker means by it rather than rely on the word alone. |
Common buying mistakes
-
Treating sweetened and unsweetened drinks as interchangeable
Tesco Groceries lists 2.5 g sugars per 100 ml and sugar in the ingredients for its Sweetened long-life drink, compared with 0.5 g sugars per 100 ml for its Unsweetened version. That difference matters when a biscuit recipe already specifies its sugar.
Check the ingredients and nutrition panel. Choose an unsweetened drink for a recipe written around that choice, or review the recipe’s sugar if you deliberately use a sweetened one.
-
Assuming long-life means filtered for baking
UHT and long-life descriptions address the unopened drink’s storage format; they do not establish a filtered specification or a difference in biscuit results.
If you are buying specifically for a filtering claim, check how the maker defines it on that product and whether it provides relevant baking guidance.
-
Using the unopened shelf life after opening
Opened-carton instructions vary: Tesco Groceries specifies 5 refrigerated days for its Sweetened drink, while Waitrose & Partners and M&S specify 3 days for the unsweetened products cited here.
Refrigerate the drink after opening and plan to use the remainder within the period on your carton.
-
Assuming dairy-free covers every allergy need
Soya itself is an allergen. M&S also states that its Unsweetened Soya Drink is not suitable for people with a nut allergy.
Check the current pack’s full ingredient and suitability statements for everyone who will eat the biscuits.

Questions about baking with soya drink
Should I use sweetened or unsweetened soya drink for biscuits?
If your biscuit recipe already sets its sugar quantity, start by checking an unsweetened drink. Tesco Groceries lists 0.5 g sugars per 100 ml for its Unsweetened long-life drink, while its Sweetened version contains added sugar and lists 2.5 g per 100 ml. If you choose the sweetened version, review the recipe’s sugar rather than assuming the drinks are interchangeable.
How long does long-life soya drink keep after opening?
Follow the opened-storage instruction on your carton, not its unopened shelf life. Tesco Groceries says to refrigerate its Sweetened drink and consume it within 5 days; Waitrose & Partners and M&S specify 3 days for the unsweetened products cited here.
Can I heat soya drink while preparing biscuit dough?
Check the product’s cooking instructions if your preparation involves heating it. Waitrose & Partners advises heating its Essential Unsweetened Soya Drink gently and taking it off the heat before it boils. That handling advice does not establish how it compares with other drinks in finished biscuits.
Can someone with a soya allergy have biscuits made with soya drink?
No: soya drink contains soya, an allergen. Check the current carton for any further warnings that matter to the people eating the biscuits; M&S, for example, states that its Unsweetened Soya Drink is not suitable for people with a nut allergy.
