For a strict low-fat choice, look for a low-fat claim and check the current label against the Food Allergen Information Association’s criterion of no more than 1.5 g fat per 100 ml for a liquid; ‘unsweetened’ alone does not establish this. Six UK pints are approximately 3.41 litres using the pint measure cited by Ratatouie, so four 1-litre cartons cover the quantity, provided their storage and after-opening instructions suit your household.
An unsweetened or plant-based description is not enough to establish total fat content. The Food Allergen Information Association gives 1.5 g fat per 100 ml as the limit for a low-fat claim on liquids; check the current carton’s claim and nutrition declaration.
The M&S, Tesco and Waitrose examples here are 1-litre cartons. Four provide 4 litres, more than the approximately 3.41 litres in six UK pints calculated from the pint measure cited by Ratatouie. Consider how many cartons you can store and finish.
Check fat and sugars separately, then read the exact carton if added calcium, iodine, vitamin D or vitamin B12 matters to you. Fortification varies between the products described by M&S, Tesco and Waitrose.
Establish whether low fat is essential before choosing a quantity or storage format: sugar wording and pack size answer different questions.
| Priority | What to check | Your needs |
|---|---|---|
| Total fat | Read fat per 100 ml on the current label. The Food Allergen Information Association gives no more than 1.5 g per 100 ml as the criterion for a low-fat claim on liquids; do not substitute an unsweetened claim. | If low fat is non-negotiable for my household, I need the total-fat figure rather than an assumption based on sugar wording. |
| Household quantity | Check the volume of each carton and the total pack volume. Using the UK pint measure cited by Ratatouie, six pints are approximately 3.41 litres; four 1-litre cartons provide 4 litres. | I want enough for the household without buying considerably more than we can use. |
| Sugars and fortification | Compare the sugar declaration separately from fat. Check the exact carton for added calcium, iodine, vitamin D and vitamin B12 if these are part of your selection. | Alongside fat content, I may prefer an unsweetened drink or particular listed additions. |
| Storage | Check whether the carton is chilled or long-life, where unopened cartons should be kept, and its refrigeration and use-within directions after opening. | Some cartons may need to wait unopened while we work through the household supply. |
| Soya allergen | Read the allergen declaration on the exact product. The Food Standards Agency identifies soya as an allergen. | If anyone in my household has a soya allergy, a soya drink is not a suitable purchase for them. |
The two descriptions refer to different nutrients. Joybuy lists 1.8 g fat per 100 ml for Alpro Soya No Sugars Long Life Drink 8 × 1 L, above the Food Allergen Information Association’s 1.5 g per 100 ml criterion for a liquid low-fat claim.
If low fat is essential, check total fat per 100 ml first; consider sugars separately.
The M&S, Tesco and Waitrose examples described here are 1-litre cartons. Six UK pints are approximately 3.41 litres using the pint measure cited by Ratatouie: three cartons fall short, while four provide 4 litres.
Choose the number of cartons from their stated volume, then consider storage and how quickly you will use them.
Tesco Longlife Soya Drink Unsweetened and Waitrose Essential Unsweetened Soya Drink are described as unsweetened and fortified. Those descriptions do not, by themselves, establish their total fat per 100 ml.
Check the current nutrition declaration before choosing either for a strict low-fat requirement.
The Food Standards Agency identifies soya as an allergen. Storage also changes after opening: the Joybuy listing for Alpro Soya No Sugars Long Life Drink 8 × 1 L instructs refrigeration and use within five days.
Avoid soya drinks for someone with a soya allergy. For other household members, open cartons as needed and follow the directions on each product’s label.
These examples illustrate different label and pack checks; a statement about one drink should not be assumed to apply across its brand’s range.
M&S describes its 1-litre Unsweetened Soya Drink as naturally low in fat and sugar, with added calcium, iodine, vitamin D and vitamin B12.
The Alpro range includes formulations with different fat and sugar descriptions; the variant matters.
Tesco describes its 1-litre Longlife Soya Drink Unsweetened as a UHT drink with added calcium, iodine, vitamin B12, riboflavin and vitamin D2.
Waitrose lists Essential Unsweetened Soya Drink as a 1-litre UHT carton with added calcium, vitamin D, vitamin B12, vitamin B2 and iodine.
This Vitasoy multipack offers individual cartons, but its 12-litre total is substantially more than a six-pint household quantity. Check its current fat declaration before choosing it for a strict low-fat requirement.

The stated 8 × 6 × 250 ml box totals 12 litres, so consider whether your household can store and use that much when you need roughly six pints. Check the current fat per 100 ml, the soya allergen declaration and the carton’s after-opening instructions.
The Food Allergen Information Association gives no more than 1.5 g fat per 100 ml as the criterion for a low-fat claim on liquids. Check total fat on the current carton; ‘unsweetened’ and ‘no sugars’ describe something different.
Six UK pints are approximately 3.41 litres using the 568.261 ml pint measure cited by Ratatouie. Four 1-litre cartons provide 4 litres; three provide less than the target.
No. Unsweetened wording does not establish total fat content. For example, Joybuy lists Alpro Soya No Sugars Long Life Drink 8 × 1 L at 1.8 g fat per 100 ml, above the Food Allergen Information Association’s 1.5 g per 100 ml criterion for a liquid low-fat claim.
Read the exact carton if added calcium, iodine, vitamin D or vitamin B12 matters to you, because the listed additions differ by product. Soya is also an allergen, as the Food Standards Agency notes, so a soya drink is unsuitable for someone with a soya allergy.
Check each carton’s unopened storage directions: UHT or long-life products and chilled products have different requirements. After opening, follow that product’s label; the Joybuy listing for Alpro Soya No Sugars Long Life Drink 8 × 1 L specifies refrigeration at +1°C to +7°C and use within five days.
