For bread dough that calls for dairy milk, an unsweetened soya drink lets you control the recipe’s sweetness while choosing a carton with clearly stated protein content. Check the allergen label and storage instructions too: a long-life carton can be kept in the cupboard before opening, but must be refrigerated and used within its stated period afterwards.
Who is this for?
Dairy-free bread bakers
If a loaf, bun or roll recipe calls for dairy milk, you need a substitute that fits the dough rather than simply a drink labelled dairy-free. King Arthur Baking identifies soya milk as an option for baking; the result in your own bread will still depend on the recipe.
Bakers controlling sweetness
An unsweetened carton gives you more control when making savoury bread or following a recipe with a set amount of sugar. Check the sugars figure on the exact variant: Alpro Original lists 2.5g per 100ml, while Tesco Soya Drink Unsweetened lists 0.4g per 100ml, according to their product information.
Households checking allergens
Dairy-free does not mean suitable for every food allergy. Soya itself needs consideration, and M&S says its Unsweetened Soya Drink is not suitable for people with a nut or peanut allergy. Read the current pack for the person who will eat the bread.
What should you check?
Start with the recipe and the carton’s formulation, then choose a pack size and storage format that fit how often you bake.

What to check |
Your needs |
| Bread dough |
Compare declared protein per 100ml and follow the bread recipe’s liquid instructions. Tesco Groceries lists 3.5g per 100ml for Tesco Soya Drink Unsweetened; Waitrose lists 3.4g per 100ml for Essential Unsweetened Soya Drink. Those figures do not predict an identical loaf. |
My recipe uses a meaningful amount of milk, so I want to compare cartons before trying a dairy-free substitution. |
| Sweetness |
Look for an unsweetened or no-sugars variant and read the sugars figure per 100ml. Alpro lists 2.5g per 100ml for Original, while Tesco Groceries lists 0.4g per 100ml for Tesco Soya Drink Unsweetened. |
For savoury bread, I would rather decide how much sugar goes into the dough myself. |
| Allergens |
Read the current ingredients and allergen information on the exact carton. Check any additional suitability warnings: M&S says its Unsweetened Soya Drink is not suitable for people with a nut or peanut allergy. |
The bread needs to meet someone’s particular allergen requirements, not just be dairy-free. |
| Storage |
Check whether the unopened carton needs chilling, then read its after-opening instructions. Waitrose says to refrigerate Essential Unsweetened Soya Drink and use it within three days of opening. |
I bake occasionally, so a cupboard carton is useful only if I can use it within the stated period once opened. |
What can go wrong?
-
Treating every soya drink as interchangeable
Original and unsweetened variants can have different sugars figures, and the compared cartons also declare different protein amounts. A change of carton can therefore change what you put into the dough, even when both products are soya drinks.
For a first attempt, choose the formulation your recipe calls for, compare the per-100ml label and note the result before changing another ingredient.
-
Assuming dairy-free covers every allergy
Soya is an allergen. Individual products can carry further warnings; M&S states that its Unsweetened Soya Drink is not suitable for people with a nut or peanut allergy.
Check the ingredients, allergen declaration and suitability warnings on the carton you are using, particularly if it replaces a previously familiar product.
-
Overlooking the opened-carton instructions
Long-life describes storage before opening. The time allowed after opening differs by product: Waitrose specifies three days for Essential Unsweetened Soya Drink, while Alpro’s No Sugars product information specifies five days.
Choose a pack size that fits your baking plans, refrigerate opened cartons and note when you opened them.
A carton left unused beyond its stated after-opening period may have to be discarded.
-
Using an online listing in place of the pack
The carton you receive is the one that matters when checking ingredients, allergens and storage directions, especially for a household with food allergies.
Use listings to narrow your choice, then read the current physical label before adding the drink to the dough.
Brand and product references
These details concern the named soya drinks, not every product made by each brand.
Alpro
Alpro has Original and No Sugars soya drink variants. Check which one a bread recipe calls for rather than treating their names as interchangeable.

- Tesco Soya Drink Unsweetened lists 3.5g protein and 0.4g sugars per 100ml.

Frequently asked questions
Can I replace dairy milk with soya drink in bread dough?
Soya drink is an option for bread recipes that call for milk; King Arthur Baking identifies it as a non-dairy baking substitute. Start with the liquid quantity in your recipe, then assess the dough and finished loaf rather than assuming every carton will produce the same result.
Should I buy unsweetened or original soya drink?
Choose unsweetened if you want to control the sweetness specified in your bread recipe. Check the exact label: Alpro lists 2.5g sugars per 100ml for Soya Original, while Tesco Groceries lists 0.4g per 100ml for Tesco Soya Drink Unsweetened.
Does dairy-free soya drink suit every food allergy?
No. Soya drink is not suitable for someone who must avoid soya, and other warnings depend on the product. M&S says its Unsweetened Soya Drink is not suitable for people with a nut or peanut allergy, so read the current carton before baking for anyone with an allergy.
How should I store an opened carton?
Refrigerate it and follow the period stated on that carton. Waitrose Essential Unsweetened Soya Drink and Sainsbury's Unsweetened Soya Drink specify use within three days of opening; Tesco Soya Drink Unsweetened and Alpro No Sugars specify five days.
