Bakers comparing fat
If you are adapting a cake, muffins, pancakes or a sauce, check the fat declaration rather than assuming all unsweetened soya drinks have the same composition.
Who is choosing a soya drink?
Vegan or dairy-free home bakers
If a recipe calls for a plant-based liquid, check the chosen carton’s ingredients, suitability statement and storage instructions before you start baking.
Bakers controlling sweetness
If the recipe already includes measured sugar, dried fruit or icing, distinguish an unsweetened soya drink from an original sweetened version.
What should you check before buying?
Compare fat and sugars using each label’s stated unit, then choose a carton whose storage and preparation instructions fit your baking plans.
| Priority | What to check | Your needs |
|---|---|---|
| Fat declaration | Read fat per 100g or per 100ml, keeping the declared unit. Marks & Spencer lists 1.4g per 100g for M&S Unsweetened; Tesco lists 1.5g per 100ml for its chilled Unsweetened drink. Do not treat the two bases as identical. | I want to know how much fat the liquid ingredient contributes before changing my recipe. |
| Sugars | Check both the variant name and sugars declaration. Waitrose & Partners lists 0.0g sugars per 100ml for Essential Unsweetened, compared with 2.5g per 100ml for Essential Original. | If my bake already contains sugar or sweet fillings, I would rather measure that sweetness in the recipe than overlook sugar in the drink. |
| Storage and heating | Check whether the carton is chilled or long-life, its instructions after opening and any cooking directions. Waitrose advises gentle heating rather than boiling its soya alternative, which can separate. | For baking planned in advance, cupboard storage may be useful; for a sauce or custard, I also need to follow the chosen carton’s heating guidance. |
| Allergy suitability | Read the current ingredients and allergen statement for every ingredient. M&S states its unsweetened soya drink is not suitable for people with nut or peanut allergies. | Before sharing a bake, I need to check that the exact products I used suit everyone who will eat it. |
What can go wrong in a bake?

Assuming “unsweetened” also means lower fat
Unsweetened describes the formulation, not a common fat figure: the checked cartons declare different amounts and do not all use the same per-100 unit.
Compare the fat line on the carton you intend to use, preserving its stated unit rather than estimating from a serving size.
-
Swapping an original drink for an unsweetened one
Waitrose & Partners lists 2.5g sugars per 100ml for Essential Original and 0.0g per 100ml for Essential Unsweetened. That difference changes what the liquid adds to a sweet bake.
If the recipe assumes an unsweetened liquid, check the exact variant before deciding whether to adjust the recipe’s sugar.
-
Boiling the drink or overlooking storage directions
Waitrose says its soya alternative can curdle or separate when heated; an opened carton also has its own storage instructions.
Follow the heating and after-opening directions on the product you buy, particularly when making a sauce or custard.
-
Assuming plant-based means suitable for every guest
Soya remains an allergy consideration, and M&S specifically says its unsweetened drink is unsuitable for people with nut or peanut allergies.
Check the current allergen statements for the drink and every other ingredient before sharing the finished bake.
Which brand ranges are relevant?
These brand examples describe particular soya drinks, not every product sold under each name; check the variant on the carton.
M&S Plant Kitchen
Its unsweetened 1-litre soya drink is an own-label option with nutrition declared per 100g.
- Marks & Spencer lists 1.4g fat and 0.4g sugars per 100g.
- M&S states this drink is not suitable for people with nut or peanut allergies.
Tesco
Tesco lists chilled and long-life versions of its own-label Unsweetened Soya Drink.
- Tesco lists 1.5g fat and 0.4g sugars per 100ml for the chilled version; its long-life version lists 2.1g fat and 0.5g sugars per 100ml.
- Check which format you are buying and read the current pack, as Tesco notes that product information can change.
Waitrose Essential
Essential Unsweetened is a UHT soya drink to consider when the sugars declaration matters to a sweet recipe.
- Waitrose & Partners lists 0.0g sugars and 1.9g fat per 100ml for Essential Unsweetened.
- Waitrose advises heating its soya alternative gently rather than boiling it because it can curdle or separate.
Alpro
Alpro Soya Light is a branded reduced-fat soya drink listed by Tesco.
- Tesco describes Soya Light as a reduced-fat drink with added calcium, iodine and vitamins B2, B12 and D2.
- For a recipe where the fat figure is decisive, compare the current carton’s per-100ml declaration with the other drinks you are considering.

Christmas baking questions
Which checked soya drink has the lowest fat figure?
Marks & Spencer lists 1.4g fat per 100g for M&S Unsweetened, while Tesco lists 1.5g per 100ml for its chilled Unsweetened drink. Because those are different measurement bases, the figures alone do not establish which has less fat on a like-for-like basis; use the current carton’s declaration when choosing.
Should I use unsweetened soya drink in a Christmas cake?
Choose an unsweetened variant if you want to account separately for the sugar in the recipe and the sugars in the liquid. Waitrose & Partners lists 0.0g sugars per 100ml for Essential Unsweetened, whereas Essential Original lists 2.5g per 100ml.
Can I heat soya drink for a sauce or custard?
For Waitrose Essential soya drink, follow Waitrose’s advice to heat gently and remove it from the heat before boiling, as it can curdle or separate. Check the directions on a different carton rather than assuming it will behave the same way.
Can I share a soya-drink bake with someone who has a soya allergy?
Do not serve a bake containing soya drink to someone with a soya allergy. Check every ingredient’s current allergen statement; M&S also states that its unsweetened soya drink is unsuitable for people with nut or peanut allergies.
How should I plan around an opened carton?
Follow the storage and use-after-opening directions for the exact carton. Tesco chilled Unsweetened says to consume it within five days of opening, while Waitrose Essential Unsweetened states three days; neither window is a rule for all soya drinks.
