For roughly six imperial pints of soya drink, four 1L cartons cover the planned volume; three do not. Choose an unsweetened recipe if the drink needs to work in both sweet and savoury brunch dishes, and check fortification if it regularly replaces dairy. Long-life cartons make it easier to buy ahead and leave spare cartons sealed, but every opened carton still needs to be stored and used as its label directs.
If guests will use it for cereal, hot drinks and cooking, calculate the total volume before choosing cartons. The Sainsbury's and Waitrose Essential products described here specify use within three days of opening, while the cited Alpro Original listing specifies five days. Leaving spare cartons sealed gives you more flexibility after the meal.
An unsweetened carton may fit both sweet toppings and savoury recipes. Compare sugars per 100ml on the exact product: Waitrose Essential Unsweetened lists 0g, Sainsbury's Unsweetened lists below 0.5g, and the cited Alpro Original listing lists 2.5g.
Check the nutrients on the particular carton rather than assuming all soya drinks have the same formulation. The UK government's SACN/COT assessment says nutrient content varies considerably between plant drinks and identifies calcium, iodine, vitamin A, riboflavin and vitamin B12 when discussing fortification comparable with semi-skimmed cows' milk.
Work out how much drink the table needs, then compare recipes and storage instructions on the cartons you intend to serve.
| Priority | What to check | Your needs |
|---|---|---|
| Volume and storage | The explanatory notes to the Product Regulation and Metrology Act 2025 give an imperial pint as about 0.568L. Six pints are therefore about 3.41L: check carton size, whether unopened cartons need chilling, and the instructions after opening. | I need enough for several brunch uses without opening every carton. Four 1L cartons cover a roughly six-pint plan; three fall short. |
| Sugars and flavour | Compare sugars per 100ml and whether the carton says unsweetened, original or sweetened. Waitrose Essential Unsweetened lists 0g, Sainsbury's Unsweetened below 0.5g, and the cited Alpro Original listing 2.5g. | For cereal with sweet toppings and for savoury cooking, I would rather choose a recipe that does not add sweetness. |
| Nutrients | Read the exact carton for calcium, iodine and vitamins, as well as protein per 100ml if that matters to your choice. The UK government's SACN/COT assessment notes that nutrient content varies considerably between plant drinks. | If soya drink regularly replaces dairy in my household, I want to check its fortification rather than treat an organic and a fortified carton as interchangeable. |
| Allergens | Read the current pack's soya declaration and any precautionary allergen statements before serving. Recheck the pack even if you have bought the product before. | Someone at the table may need an allergen check; a dairy-free description does not answer whether a soya drink is suitable for them. |
The UK government's SACN/COT assessment says plant-drink nutrient content varies considerably. Protein content or a dairy-free description does not establish which vitamins and minerals have been added.
If the drink regularly replaces dairy, compare the exact carton's calcium, iodine and vitamin declarations. Check an organic carton separately rather than assuming it has the same fortification as another recipe.
The cited Waitrose Essential Unsweetened, Sainsbury's Unsweetened and Alpro Original listings give different sugars-per-100ml figures: 0g, below 0.5g and 2.5g respectively.
Check both the recipe name and the sugars line if one drink needs to work across cereal, hot drinks and savoury dishes.
Opening a carton starts its refrigerated use period. The cited Sainsbury's and Waitrose Essential products specify three days after opening; the cited Alpro Original listing specifies five.
Keep spare cartons sealed and note when you open each one. Follow the storage instructions on the cartons you actually buy.
Unused opened drink may need to be discarded when its stated use period has passed.
Soya drink contains soya. A dairy-free or vegan description does not make it suitable for someone with a soya allergy.
Before serving, read the current carton's allergen declaration and precautionary statements rather than relying only on an online listing.
These ranges illustrate different recipes and storage formats; check the particular carton rather than applying one product's details to a whole brand.
Alpro has original, no-sugars and organic soya-drink variants, so the variant name matters when comparing cartons.
Its Unsweetened Soya Drink 1L is a chilled own-label option.
Essential Unsweetened Soya Drink is a 1L UHT option for buying ahead.
Tesco lists separate 1L long-life own-label soya drinks labelled Unsweetened and Sweetened.
These soya drinks include a long-life multipack and 1L options relevant to planning brunch volume. Check the sale-unit quantity before using any listing to work out how many cartons you will receive.

The stated 8 x 1L pack gives a brunch host separate long-life cartons to open as needed. It exceeds a roughly six-pint volume plan, so keep any spare cartons sealed and follow the pack's instructions once a carton is opened. Check the current allergen declaration before serving.

This long-life soya drink is an option to consider for cereal or hot drinks. Its listing title includes “6”, while its description states 1L; confirm the sale-unit quantity before counting it towards a six-pint brunch. Compare its sugars and nutrient panel with your preferred recipe.

A 1L carton can contribute to the brunch volume, but one carton will not cover a roughly six-pint plan. If you want an unsweetened drink or use soya drink regularly instead of dairy, check this carton's sugars and nutrient declarations before choosing it. Read the soya allergen declaration before serving.
No. Four 1L cartons cover a target of roughly six imperial pints, while three do not: the explanatory notes to the Product Regulation and Metrology Act 2025 define an imperial pint as about 0.568L, making six pints approximately 3.41L. Open only the cartons you need at brunch and follow each product's storage instructions.
Choose long-life cartons if you want to buy ahead and store them as the unopened pack permits; a chilled product needs refrigerator space from purchase. Neither format removes the need to refrigerate opened cartons: the cited Sainsbury's and Waitrose Essential products specify use within three days of opening, while the cited Alpro Original listing specifies five.
Check the exact carton's fortification and nutrition panel. The UK government's SACN/COT assessment says plant-drink nutrient content varies considerably and identifies vitamin A, riboflavin, vitamin B12, calcium and iodine when discussing fortification comparable with semi-skimmed cows' milk.
Do not assume so. The UK government's SACN/COT assessment distinguishes organic plant drinks from fortified alternatives, while nutrient content varies between products. Read the particular organic carton's nutrient declaration if fortification matters to your choice.
A drink containing soya is not suitable for someone with a soya allergy; check the current pack's allergen declaration before serving. Also read product-specific age guidance: the cited Sainsbury's product says it is not suitable as a main milk-drink alternative for children under two, and Waitrose Essential states it is not suitable for children under two.
