Hosts serving dairy-free guests
Choose a format that covers likely use in drinks or recipes while allowing spare cartons to stay unopened. Ask about allergies separately: dairy-free soya drink still contains soya.
Who needs which format?
The serving format matters as much as the number of cartons: shared drinks, coffee service and child-specific portions call for different checks.
Hosts making coffee after dinner
A barista-labelled case is worth considering if you plan to make cappuccinos or lattes. Plenish describes its 6 × 1L barista soya case as foamable; that is the manufacturer’s description, not an independent comparison with standard cartons.
Parents choosing cartons for a child
Check the stated age group rather than choosing by carton size alone. The Alpro Growing Up 3 × 250ml multipack listed by ASDA is marketed for children from age 1.
What should you check?
Start with how guests will use the drink, then compare carton size, the label and storage instructions.
| Priority | What to check | Your needs |
|---|---|---|
| Carton format | Compare 1L cases with individual cartons; check the carton count against your guest plans and storage space. Keep reserve cartons unopened until needed. | I’m serving soya drink to several adults, but I don’t yet know how many will ask for it. |
| Coffee service | Check whether the named product is intended for foaming. Plenish calls its 6 × 1L barista case foamable, but this is its own product claim. | Cappuccinos or lattes are part of the evening, so I want to choose a carton intended for that use. |
| Ingredients and nutrients | Read the individual carton’s sugars and nutrient information. The UK SACN and COT’s 2025 assessment notes that plant-drink nutrient content varies and that UK products labelled organic cannot be fortified. | A guest has asked for a particular sugar level or a fortified dairy alternative; I need to compare the actual labels. |
| Allergens | Check the physical carton’s ingredient and allergen declaration before serving, including when the drink is described as dairy-free or vegan. | Someone may need to avoid soya, so I need their requirements before deciding what to serve. |
| Small portions | Check who the product is intended for. ASDA lists Alpro Growing Up 3 × 250ml as a drink for children from age 1. | Individual cartons would be convenient, but I don’t want to mistake a child-specific drink for a general adult serving. |
What can catch hosts out?
-
Choosing small cartons by size alone
The Alpro Growing Up 3 × 250ml multipack is marketed for children from age 1; its small-carton format does not make it a general adult dinner-party drink.
For adult guests, compare shared 1L cartons first. Check the intended user on any individual-carton product you consider.
-
Assuming an organic carton is fortified
The UK SACN and COT’s 2025 assessment says nutrient content varies between plant drinks and that products labelled organic in the UK cannot be fortified.
If added calcium, iodine or vitamins matter to your choice, compare the nutrient information on the exact cartons.
-
Opening the whole case before guests arrive
Once a carton is open, its own refrigeration and use-by-opening instructions become relevant, even if it was stored unopened beforehand.
Open cartons as needed and follow the storage instructions printed on each one.
Unfinished opened cartons can mean avoidable waste.
-
Treating dairy-free as suitable for every allergy
A soya drink can suit a guest avoiding dairy while still being unsuitable for someone with a soya allergy.
Ask guests about allergies in advance, check the carton’s allergen declaration and arrange a non-soya option where needed.
Relevant brand references
These named products illustrate different formats and labels; the brand references do not imply that every product in a range has the same ingredients.
Alpro
Alpro has a standard 1L Soya Original drink and a separate Growing Up small-carton multipack.
- Alpro UK lists 3.3g protein, 120mg calcium and 22.5µg iodine per 100ml for Soya Original 1L.
- The Growing Up 3 × 250ml multipack listed by ASDA is marketed for children from age 1; do not apply the standard drink’s figures to it.
Plenish
Plenish lists an 8 × 1L standard soya case and a 6 × 1L barista soya case.
- Plenish describes its barista case as foamable for coffee drinks.
- Both named cases are labelled organic. The UK SACN and COT’s 2025 assessment says products labelled organic in the UK cannot be fortified; check their labels if added nutrients matter.
M&S Plant Kitchen
The M&S Unsweetened Soya Drink is a 1L carton to consider when buying cartons individually rather than choosing a case.
- Marks & Spencer lists added calcium, iodine, vitamin D and vitamin B12 for this named drink.
- Check the carton you buy for its current ingredients and nutrient information.
Waitrose Essential
Essential Original Soya Drink is a 1L long-life carton for hosts choosing the number of cartons individually.
- Waitrose & Partners describes this named drink as sweetened and fortified with calcium, vitamins D, B12 and B2, and iodine.
- Follow the post-opening storage instructions on the carton purchased.
Joybuy soya drink multipacks
These options cover a shared 1L-carton case and a case of individual 250ml cartons. Choose between them according to how you plan to serve guests, rather than assuming the smaller carton is the smaller overall purchase.

Alpro Soya No Sugars Long Life Drink, 8 × 1L
For shared service, this pack contains eight 1L long-life cartons, so spare cartons can stay unopened until needed. Check the carton’s soya allergen declaration and follow its storage instructions after opening.
No image available
Vitasoy Soya Drink Regular, 8 × 6 × 250ml
For separately opened portions, this box is listed as eight packs of six 250ml cartons. Check whether that quantity fits your guest plans and storage space, and read the cartons for intended use and allergen information before serving.
Dinner-party questions
Should I choose 250ml cartons for an adult dinner party?
Choose them if separate portions suit your plans, but check the intended user of the exact product. ASDA lists Alpro Growing Up 3 × 250ml as a child-specific drink for ages from 1 year; its format alone does not establish suitability as a general adult party drink.
Is organic soya drink necessarily fortified?
No. The UK SACN and COT’s 2025 assessment says products labelled organic in the UK cannot be fortified and that plant-drink nutrient content varies. If added nutrients matter, read the exact carton’s nutrition information.
What should I do with a carton after opening it?
Follow the refrigeration and consumption instructions on that carton rather than applying one brand’s instructions to another. Keep reserve cartons unopened until you need them.
How can I check whether soya drink is suitable for a guest?
Ask about allergies before serving and check the physical carton’s ingredient and allergen declaration. Dairy-free does not mean soya-free; have another option available if a guest needs to avoid soya.
