Bakers controlling the sugar in a vegan dough
If your recipe specifies its own sugar quantity, compare unsweetened and no-sugars cartons rather than assuming every soya drink contributes the same amount.
Who is this choice for?
Bakers making sweet or enriched rolls
An original or sweetened drink may fit a dough where that sweetness is intentional. The Great British Bake Off’s vegan milk-bread recipe uses room-temperature soya milk, but it does not establish a preferred retail carton.
Households checking food allergies
Check the exact carton before baking for someone with an allergy. GOV.UK identifies soya beans among the 14 regulated allergens, while the sampled M&S soya-drink listings also carry nut and peanut suitability warnings.
What should you check before baking?
Choose the sweetness that fits the recipe, then check how you will use and store the carton.
| Priority | What to check | Your needs |
|---|---|---|
| Recipe sweetness | Read sugars per 100 ml, or per 100 g where that is how the carton declares them. Alpro UK lists 0 g per 100 ml for Soya No Sugars and 2.5 g per 100 ml for Soya Original; compare like units. | I’m following a dough formula with a set sugar quantity and don’t want the liquid to change it unexpectedly. |
| Bread method | Check whether your recipe calls for soya drink and specifies its temperature or quantity. The Great British Bake Off’s vegan milk-bread recipe uses 260 ml at room temperature in a yeast dough; it does not establish a substitution rule for every loaf. | I want to use a plant-based liquid in a recipe that gives clear instructions for it. |
| Allergy information | Read the current ingredients list and any additional suitability warnings. GOV.UK says regulated allergens such as soya beans must be clearly labelled in the ingredients list of prepacked food containing them. | When I bake for someone with an allergy, I need to check that particular carton, not rely on a vegan or dairy-free description. |
| Storage | Distinguish unopened long-life storage from instructions after opening. Waitrose & Partners says its Essential Unsweetened drink should be refrigerated below 5°C and used within three days of opening; its listing for Alpro Soya Long Life No Sugar says refrigerate and use within five days. | I bake occasionally, so I need a carton size and opened-carton timeframe I can manage. |
| Protein declaration | Compare the same nutrition measure on the cartons you are considering. Tesco Groceries lists 3.5 g protein per 100 ml for Tesco Unsweetened; Sainsbury’s lists 2.2 g per 100 ml for its Unsweetened drink. Neither figure establishes how a loaf will turn out. | I may want to compare labels, but I won’t use protein alone as a prediction of rise or crumb. |
Common mistakes to avoid
-
Assuming all soya drinks have the same sweetness
Alpro UK declares 0 g sugars per 100 ml for Soya No Sugars and 2.5 g per 100 ml for Soya Original. Swapping between them changes the declared sugars contributed by the liquid.
Read the exact carton’s sugars line and ingredients before using it in a recipe with a specified sugar quantity.
-
Using protein as a guarantee of a better loaf
Protein declarations help distinguish cartons, but they do not establish which drink will give your recipe a particular rise, crumb or flavour.
If you want to compare results, keep the rest of an established recipe the same when trying a different carton.
-
Assuming dairy-free covers every allergy
GOV.UK identifies soya beans as a regulated allergen. The sampled M&S unsweetened and sweetened soya-drink listings also warn that those products are not suitable for people with nut or peanut allergy.
Check the current product’s ingredients and suitability warnings for the person who will eat the bread.
-
Treating long-life as an after-opening instruction
A long-life carton can still require refrigeration and prompt use once opened. Waitrose & Partners gives different after-opening timeframes for its Essential Unsweetened drink and the Alpro long-life drink in its listings.
Plan around the carton size you will use and follow its own storage instructions after opening.

Bread-baking questions
Can soya drink be used in yeast bread?
Yes, in a recipe designed to use it: The Great British Bake Off’s vegan milk-bread recipe specifies 260 ml of room-temperature soya milk in a yeast dough. That example does not establish a one-for-one substitution for every bread formula.
Should I use unsweetened or original soya drink?
Start with unsweetened or no-sugars soya drink when you want the recipe’s sugar quantity to determine sweetness. Use an original or sweetened drink when its declared sugars are part of your intended dough: Alpro UK lists 0 g sugars per 100 ml for Soya No Sugars and 2.5 g per 100 ml for Soya Original.
Does long-life soya drink need chilling after opening?
Yes, for the sampled products: Waitrose & Partners says to refrigerate Essential Unsweetened below 5°C and use it within three days of opening. Its Alpro Soya Long Life No Sugar listing says to refrigerate after opening and use within five days. Follow the instructions on the carton you buy.
What allergy information should I check?
Check the current carton’s ingredients and additional suitability warnings before baking for someone with an allergy. GOV.UK lists soya beans among the 14 regulated allergens and says allergens in prepacked food must be clearly labelled within the ingredients list; individual drinks may carry further warnings.
