Small households making a short top-up
A 1L carton lets you open one carton at a time. The Waitrose Essential and M&S Plant Kitchen unsweetened cartons both instruct you to refrigerate after opening and use within three days.
Who is each format for?
Shoppers looking for unsweetened soya drink
Compare the exact variant rather than relying on the brand name. Alpro Unsweetened and Waitrose Essential Unsweetened are distinct choices from sweetened or Original formulations; check each carton’s nutrition and fortification labels.
Households keeping sealed cartons in reserve
Long-life cartons can be bought for later use, but the total quantity still matters. Tesco Groceries lists Alpro Unsweetened as 6 × 1L, not as a six-pint bottle; check the pack size and current stock before planning around it.
What should you check before buying?
Start with the total pack volume, then compare the formulation and instructions on the exact cartons you would use.
| Priority | What to check | Your needs |
|---|---|---|
| Pack quantity | Read the total volume and carton count. Six UK pints are about 3.4L; Tesco Groceries lists its Alpro Unsweetened 6 × 1L pack as 6L. | For a short top-up, I would rather open one carton at a time. A larger pack only makes sense if I will use its full quantity. |
| After opening | Check the exact carton’s refrigeration and use instructions. Waitrose Essential and M&S Plant Kitchen Unsweetened specify three days; Tesco’s Alpro Unsweetened multipack listing specifies five days per opened carton. | If I use soya drink slowly, the opened-carton period matters more than how many sealed cartons I can store. |
| Formulation | Compare the variant name, ingredients and sugars on the nutrition label. Sainsbury’s lists separate 1L sweetened and unsweetened own-label drinks; Alpro Original is a different variant from Alpro Unsweetened. | I want to know whether I am picking an unsweetened drink, rather than assuming every soya carton has the same formulation. |
| Fortification | Check the named nutrients on the exact carton. Waitrose Essential Unsweetened lists added calcium, vitamins D, B12 and B2, and iodine; the Alpro Original listing names calcium, iodine and vitamins B2, B12 and D2. | Where particular added nutrients matter to me, I need to compare the individual labels, not just the words ‘soya drink’. |
| Allergens | Read the current ingredients and allergen statement on the physical pack. The Food Standards Agency identifies soya as an allergen; M&S also labels its Plant Kitchen Unsweetened drink unsuitable for people with a nut or peanut allergy. | If an allergy applies in my household, the specific pack’s allergen information is essential before anyone uses it. |
Common buying mistakes
-
Reading ‘6 × 1L’ as ‘six pints’
Tesco Groceries lists the Alpro Unsweetened multipack as 6L. That is more than the roughly 3.4L represented by six UK pints and takes more storage space than the intended size.
Check both the number of cartons and the total net contents before choosing a pack.
-
Buying several cartons without planning when to open them
Opened-carton instructions differ: the Waitrose Essential and M&S Plant Kitchen unsweetened cartons specify three days, while Tesco’s Alpro Unsweetened multipack listing specifies five days.
For a brief top-up, choose a quantity you expect to use and follow each opened carton’s refrigeration instructions. Confirm current stock before relying on a particular multipack.
An opened carton left beyond its stated use period may need to be discarded.
-
Assuming every soya drink has the same formulation
Alpro Original and Alpro Unsweetened are different variants, and Sainsbury’s lists separate sweetened and unsweetened 1L drinks. Added nutrients also differ by product.
Compare the exact carton’s ingredients, sugars and named added nutrients rather than relying on the brand or category alone.
-
Overlooking the allergen statement
Soya is an allergen, according to the Food Standards Agency. M&S also marks its Plant Kitchen Unsweetened carton as unsuitable for people with a nut or peanut allergy.
Do not use a soya drink where a soya allergy applies, and check the current pack for any other relevant allergen warnings.

This Alpro Plant Protein listing is marked 1L and may be relevant to a top-up, but its leading ‘6’ makes the total carton count worth confirming before you choose it.

6 Alpro Plant Protein 1L
Check the total carton count and pack volume before treating this as either a single-carton top-up or a multipack: ‘6’ and ‘1L’ both appear in the name. This is not the unsweetened option. It contains soya, so check the current pack’s allergen information where relevant.
Questions about soya-drink packs
Is a 6 × 1L soya-drink pack the same as six pints?
No. Tesco Groceries lists Alpro Unsweetened 6 × 1L as 6L, while six UK pints are about 3.4L. If you need that particular family size, check the total volume stated on the pack rather than the number of cartons.
How long can I keep a carton after opening it?
Follow the instructions on the exact carton. Waitrose Essential Unsweetened and M&S Plant Kitchen Unsweetened say to refrigerate after opening and consume within three days; Tesco’s Alpro Unsweetened 6 × 1L listing says to refrigerate and use an opened carton within five days.
Which label details help distinguish fortified soya drinks?
Compare the named added nutrients and the nutrition panel on each variant. Waitrose Essential Unsweetened lists added calcium, vitamins D, B12 and B2, and iodine; the Alpro Original listing names calcium, iodine and vitamins B2, B12 and D2. Do not assume every soya drink has the same formulation.
Is soya drink suitable for someone with a soya allergy?
No: soya is an allergen, as identified by the Food Standards Agency, and soya drinks contain soya. Check the current physical pack for its full allergen statement, including any other warnings relevant to the household.
