Hosts serving several guests
If you are aiming for roughly four pints, plan the total volume across cartons and consider how many you can keep chilled once opened.
Who is this for?
Shoppers comparing sugar levels
Unsweetened, no-sugars and original soya drinks have different nutrition figures. Compare the per 100ml sugar value on the exact carton you intend to serve or use in a recipe.
Hosts checking guests’ dietary needs
Keep each carton available so guests can check its current allergen statement. Check any age-suitability information and storage directions before serving, too.
What should you check?
Work out the quantity first, then compare cartons for the recipe or guests and plan how you will keep opened drinks cold.
| Priority | What to check | Your needs |
|---|---|---|
| Quantity | Four UK pints are about 2.27 litres. Check each pack’s total volume, especially when a listing could describe multiple 1L cartons. | I need enough for the guests and recipes, without opening every carton at once. |
| Sugar and flavour | Compare sugars per 100ml on the exact variant. Alpro UK lists 0.0g for Soya No Sugars and 2.5g for Soya Original. | For this drink or recipe, would I rather use an unsweetened carton or one with a sweeter flavour? |
| Protein and fortification | Compare protein per 100ml and the nutrients listed on each carton. Sainsbury's lists 2.2g protein for its Unsweetened Soya Drink and 5.0g for its Sweetened High Protein Soya Drink. | Protein content or particular added nutrients may matter to my choice, so I want to compare the actual products rather than assume all soya drinks match. |
| Cold storage | Read the after-opening instructions. Sainsbury's, Waitrose and M&S product pages instruct shoppers to refrigerate the cited cartons and use them within three days. The Food Standards Agency advises keeping foods normally refrigerated cool outdoors. | Can I keep the cartons I open cold throughout preparation and serving? |
| Guest suitability | Check the current carton’s allergen statement and any age-suitability information; do not assume different brands or variants carry identical instructions. | Guests need to be able to check whether the particular drink being served is suitable for them. |
BBQ shopping pitfalls
-
Shopping for a four-pint bottle without checking volume
Four UK pints are about 2.27 litres, while the cited Alpro and retailer products are 1L cartons. A single carton will not meet that quantity target.
Calculate the total you need, then check the number and volume of cartons in each pack before ordering.
-
Assuming every soya drink has the same nutrition figures
Sainsbury's lists 2.2g protein per 100ml for its Unsweetened Soya Drink and 5.0g per 100ml for its Sweetened High Protein Soya Drink; the latter is sweetened.
Compare sugars, protein and listed fortification on the exact variants you are considering.
-
Opening all the cartons before guests arrive
The cited Sainsbury's, Waitrose and M&S cartons require refrigeration after opening and use within three days. The Food Standards Agency advises keeping foods normally refrigerated cool outdoors.
Open cartons as needed and use a cool box or cool bag with ice or frozen gel packs for items that need to stay chilled.
Cartons opened unnecessarily may go unused within their stated after-opening period.
-
Putting out drinks without their cartons
Guests may need to check the exact product’s allergen and suitability information before accepting a drink.
Keep the current carton label available alongside anything you pour or use in a recipe.

Frequently asked questions
Do I need a four-pint soya milk bottle for a BBQ?
No: you can plan the required volume using cartons. The cited Alpro, Tesco, Sainsbury's, Waitrose and M&S examples are 1L products; four UK pints are about 2.27 litres, so three 1L cartons exceed that quantity. Check the total volume of any multipack before ordering.
Which cartons should I compare if I want less sugar in the drink?
Start with unsweetened or no-sugars variants and compare their labels. Alpro UK lists 0.0g sugars per 100ml for Soya No Sugars, while Sainsbury's lists less than 0.5g per 100ml for its Unsweetened Soya Drink; sweetened variants have different figures.
How should I keep opened cartons cold at an outdoor BBQ?
Follow each carton’s after-opening directions and refrigerate it when it is not being served. The cited Sainsbury's, Waitrose and M&S pages specify use within three days of opening. For foods normally kept in the fridge, the Food Standards Agency advises a cool box or cool bag with ice or frozen gel packs; in extremely hot weather, it advises using food that has been out of the fridge within two hours.
What should I check before serving soya drink to guests?
Check the current carton’s allergen statement, ingredients and any age-suitability directions for the particular guest. Keep the carton available when pouring drinks or preparing recipes so guests can inspect the information themselves.
