What to check before buying
Start with the volume the recipe actually requires, then choose a carton whose sweetness and ingredients fit that recipe.
| Priority | What to check | Your needs |
| Recipe volume |
Confirm whether four pints is the liquid quantity, not a requested pack size. Four UK pints are about 2.273 litres; check each product’s total volume and pack count. |
I need enough for the full batch. If the recipe calls for at least four pints, three 1-litre cartons exceed that volume, while two fall short. |
| Sweetness |
Read both the ingredients and sugars per 100 ml. A no-added-sugar description and the declared sugars value answer different questions. |
My recipe already measures out sugar, so I want to know whether the drink brings additional sweetness. A sweetened drink may be suitable when that fits the recipe. |
| Ingredients and fortification |
Compare the exact ingredient lists and any declared added calcium, iodine or vitamins. The UK SACN and COT assessment notes that plant-based drinks vary considerably in nutrient content. |
I might prefer a short organic ingredient list, or I might want a carton with specified added nutrients; I should not assume one has the other’s composition. |
| Allergens and leftovers |
Read the soya declaration and any precautionary nut statement. Check the carton’s refrigeration and use-after-opening instructions before opening several. |
If I am baking for someone with an allergy, the current allergen label matters. For a large batch, I also want a plan for drink left in opened cartons. |
Brand and product-line references
These examples show why the exact variant matters: an original, unsweetened or organic drink can have a different ingredient and nutrient declaration.
Alpro
Alpro has Original, no-sugars and organic soya-drink variants; check which one a recipe calls for rather than relying on the brand name alone.
- Alpro’s Original product lists sugar as an ingredient, making the variant important when sweetness is measured separately.
- Do not carry the Original product’s ingredients or nutrient declaration across to Alpro’s other variants.
Sainsbury's
Its Unsweetened Long Life Soya Drink is a 1-litre UHT option with declared added calcium, iodine, vitamin D and B12.
- The unsweetened declaration is relevant when a cake recipe specifies its sugar separately.
- The product instructions call for refrigeration after opening and use within three days; check the current carton.
Essential Waitrose
Essential Unsweetened Soya Drink is a 1-litre long-life option with declared added calcium, iodine and selected vitamins.
- Its product information declares 0.0 g sugars per 100 ml.
- Waitrose cautions that soya alternatives can separate during cooking and advises gentle heating rather than boiling; this is not a prediction of cake-baking results.
Plenish
Plenish Organic No Added Sugar Soya lists spring water and organic soya beans for shoppers comparing ingredient lists.
- The product declaration lists no added sugar, oils or additives.
- Its product information includes a may-contain-nuts statement. Check its nutrient declaration rather than assuming it matches a fortified drink.

Alpro Soya No Sugars Long Life Drink 8 x 1L
The no-sugars variant is worth considering when the cake recipe measures sugar separately. Its stated 8 x 1L pack exceeds a four-pint volume requirement by a considerable margin, so plan how you will use the remaining cartons. Contains soya.

6 Alpro Soya Drink OG
Consider this variant if you are comparing Alpro soya drinks by their ingredient declarations. Confirm what the leading “6” means for the pack count and total volume before relying on it for a four-pint recipe. Check the current carton’s allergen information.

Yeo's Soy Bean Drink 1L
A 1-litre carton is relevant if the recipe allows this drink’s declared ingredients and sweetness. One carton does not cover four UK pints: check how many units you need and read the current sugar and soya-allergen declarations.

6 Alpro Plant Protein 1L
If you are considering this soya drink for a cake, check its sugar declaration against the recipe. The name specifies 1L but does not establish what the leading “6” represents; confirm the total volume before buying for a four-pint batch. Contains soya.

Yon Ho Original Soy Milk 300 ml x 3
The three 300 ml units total 900 ml, so one pack falls well short of a four-pint recipe. Check the quantity you would need, the drink’s sugar declaration and the current soyabean-allergen information before choosing these smaller units for baking.

Questions about baking with soya drink
Do I need a four-pint bottle of soya drink?
No, if four pints is the amount your recipe requires, you can add up the volume of smaller cartons. Legislation.gov.uk defines a UK pint as 0.56826125 litres, making four pints about 2.273 litres; three 1-litre cartons provide more than that amount. Check whether the recipe genuinely calls for four pints of liquid.
Should I use unsweetened or original soya drink in a cake?
Choose an unsweetened drink when you want the recipe’s measured sugar to set the sweetness. An original drink can differ: Alpro Soya Original lists sugar as an ingredient and reports 2.5 g sugars per 100 ml. Check the exact variant if the recipe allows sweetness from the drink.
Does an organic soya drink have the same added nutrients as a fortified one?
Do not assume their nutrient declarations match. The UK SACN and COT assessment notes considerable variation among plant-based drinks; check the exact carton for declared calcium, iodine and vitamins if those details matter to your purchase.
Can someone with a soya allergy have a cake made with soya drink?
No: soya drink contains soya, so do not use it for someone with a soya allergy. Check the current pack for other relevant warnings too; the Plenish organic product, for example, carries a may-contain-nuts statement.
What should I do with soya drink left after baking?
Follow the storage instructions on the carton you opened. The Sainsbury's and Essential Waitrose products described here specify refrigeration and use within three days after opening, while the Plenish product specifies four days. Leaving unopened cartons sealed until needed can avoid opening more than the recipe requires.
