Who is this choice for?

People who prefer an unsweetened evening drink

If the sugar figure matters to you, compare labels per 100ml. Waitrose & Partners lists 0g sugars for Essential Unsweetened; Sainsbury's lists less than 0.5g for its Unsweetened Soya Drink.

Households that use soya drink regularly

A larger supply may suit you if you use cartons across drinks, cereal or cooking. Check where unopened cartons must be kept and how soon each one must be used after opening.

People who prefer a sweeter drink

A sweetened carton is a distinct choice rather than an equivalent unsweetened option. Tesco Groceries lists 2.5g sugars and 42kcal per 100ml for Tesco Longlife Sweetened Soya Drink.

What should you check?

Start with the label on the drink you would actually use, then consider whether the pack and opened-carton instructions fit your routine.

Priority What to check Your needs
Sugars and flavour Compare sugars per 100ml on the same basis. Waitrose & Partners lists 0g for Essential Unsweetened, Sainsbury's lists less than 0.5g for Unsweetened, and Tesco Groceries lists 2.5g for Longlife Sweetened. I would choose an unsweetened carton if a lower listed sugar figure matters more to me than a sweeter flavour.
Added nutrients Read the exact carton for added calcium, iodine, vitamin D and vitamin B12; do not assume an organic soya drink has the same fortification as another product. If soya drink is a regular choice for me, I want to know which nutrients the particular carton lists.
Pack and storage Check carton count, unopened storage instructions and the refrigerated use-within period after opening. The cited retailer labels give different periods: three days for Sainsbury's Unsweetened and Waitrose Essential Unsweetened, and five days for Tesco Longlife Sweetened. A multipack only fits my routine if I have room for the unopened cartons and can finish each opened one within its label period.
Allergens and age labels Read the physical pack for its soya allergen declaration and any age-related warning. The Food Standards Agency identifies soya as an allergen. I need to check suitability before serving soya drink to someone with a soya allergy or buying it as a main milk drink for a young child.

Mistakes to avoid

  • Assuming all soya drinks have the same added nutrients

    Waitrose & Partners lists spring water and organic soybeans as the two ingredients in Plenish Organic Soya, while its Essential Unsweetened drink lists added calcium, iodine and vitamins.

    If fortification matters to you, compare the ingredient and nutrition panels of the exact cartons rather than relying on an organic or plant-based description.

  • Picking sweetened soya drink without checking the label

    Tesco Groceries lists 2.5g sugars per 100ml for Longlife Sweetened Soya Drink; the cited unsweetened Waitrose and Sainsbury's products list 0g and less than 0.5g respectively.

    Compare the per-100ml figures and choose a sweetened carton when that flavour is what you want.

  • Treating a multipack as one long-lasting opened carton

    Opening one carton starts that carton's refrigerated use-within period. The cited product labels specify periods ranging from three to five days.

    Check storage directions for unopened cartons and plan to use each opened carton within its own label period.

    Buying more than you can use may leave opened drink to discard.

  • Overlooking the soya allergen declaration

    The Food Standards Agency identifies soya as an allergen that can pose a risk to someone with a soya allergy.

    Anyone with a soya allergy should not drink soya drink. Check the current physical-pack label, particularly if the product is unfamiliar or has changed.

Questions about soya drink

Should I choose unsweetened soya drink for a midnight snack?

Choose unsweetened if a lower listed sugar figure is your priority. Waitrose & Partners lists 0g sugars per 100ml for Essential Unsweetened, Sainsbury's lists less than 0.5g for Unsweetened, and Tesco Groceries lists 2.5g for Longlife Sweetened.

Does organic soya drink have the same added nutrients as fortified soya drink?

Not necessarily; check the exact carton. Waitrose & Partners lists spring water and organic soybeans as the two ingredients in Plenish Organic Soya, whereas the cited fortified supermarket drinks list added calcium, iodine and vitamins.

How soon should I use an opened carton?

Follow its own label. Sainsbury's Unsweetened and Waitrose Essential Unsweetened specify three days after opening, Tesco Longlife Sweetened specifies five days, and Waitrose & Partners lists four days for Plenish Organic Soya. Follow each product's refrigeration instructions too.

Can someone with a soya allergy drink soya milk?

No. The Food Standards Agency identifies soya as an allergen that can pose a risk to someone with a soya allergy. Read the allergen declaration on the current pack.

Can a standard soya drink be a young child's main milk drink?

Do not assume that every carton is suitable: check its age warning and seek appropriate healthcare advice for a child with an allergy or particular nutritional needs. Waitrose & Partners states that Essential Unsweetened is not suitable for children under two. In guidance dated February 2026 for children with cow's-milk protein allergy, NHS North West Knowledge Now notes that soya may not suit some children because of cross-reactivity.
