Who is each drink for?

Students drinking with lunch between lectures

Choose by the drink you want with your meal: fruit-purée texture from a smoothie or carbonation from a sparkling fruit drink. For fruit juice and smoothies, the NHS advises a maximum of 150ml a day, taken with a meal.

Students who specifically want fizz

Look for carbonation in the description rather than relying on fruit imagery or a smoothie-related search term. Tesco describes Appletiser as sparkling apple juice from concentrate; compare its serving size and sugars with any smoothie you are considering.

Students buying for several lunches or to share

A 750ml bottle calls for a plan for the remaining drink. Check its refrigeration and after-opening instructions: Tesco’s listing for Naked Blue Machine says to keep it refrigerated and consume it within five days of opening.

What should you check before buying?

Still fruit smoothie

Choose when: You want a fruit-purée drink rather than carbonation with lunch.

Trade-off: A smoothie can still contain sugars; Tesco lists 15g per 150ml serving for Strawberry Sensation.

Sparkling fruit drink

Choose when: Fizz matters more to you than smoothie texture.

Trade-off: Carbonation does not tell you the sugar content; Tesco lists 26g sugars per 250ml serving for Appletiser sparkling apple juice.

Priority What to check Your needs
Drink format Read the product description for fruit purée or crushed fruit, or for carbonation. The cited supermarket listings place smoothies and sparkling drinks in separate categories. If I want a smoothie’s texture, a fizzy fruit drink will not serve the same purpose. If fizz is the point, I should look for a sparkling drink.
Sugars and serving Compare sugars using the same nutrition basis and the amount you plan to drink. Tesco lists 15g per 150ml for Strawberry Sensation smoothie and 26g per 250ml for Appletiser; those are different serving sizes. The NHS advises limiting fruit juice and smoothies to 150ml a day with a meal. I may drink the whole bottle or can at lunch, so I want to check its volume as well as the sugars shown on the label.
Pack size Check the bottle or can volume, the number of units in a multipack and any stated serving size. A pack quantity is not a suggested amount to drink at one lunch. For a short break, I might want one container; a larger bottle or multipack makes more sense if I can use the rest later.
Storage Read the unopened and after-opening directions on the pack. Tesco’s Naked Blue Machine listing specifies refrigeration and consumption within five days after opening. If I am carrying a partly used bottle between lectures, I need to know whether I can follow its chilled-storage instructions.

Common buying mistakes

  • Assuming a sparkling fruit drink is a smoothie

    The cited Sainsbury’s and M&S listings describe smoothie ranges separately from sparkling drinks, while Tesco describes Appletiser as carbonated apple juice. A fizzy choice may therefore miss the fruit-purée texture you wanted.

    Decide whether texture or carbonation matters first, then check the individual product description.

  • Reading “no added sugar” as “no sugar”

    Waitrose lists 10g sugars per 100ml for the cited Innocent smoothie, despite its no-added-sugar description. Tesco lists 26g per 250ml serving for Appletiser sparkling apple juice.

    Read the sugars figure alongside the serving volume rather than judging either drink by wording on the front of the pack.

  • Buying a large bottle for one short break

    A 750ml bottle leaves some drink for later if you do not finish it at lunch. For Naked Blue Machine, Tesco specifies refrigeration and consumption within five days after opening.

    Check the pack size and storage directions before choosing a bottle to carry or share.

    Without suitable storage, some of an opened bottle may go unused.

Brand and retailer references

These examples help distinguish the drink formats and label details; a brand’s inclusion does not make every product in its range suitable for the same lunch.

Innocent

Innocent describes its smoothies as crushed fruit drinks and says they have no added sugar.

  • A reference point if you are looking for a conventional smoothie rather than carbonation.
  • No added sugar does not mean sugar-free: Waitrose lists 10g sugars per 100ml for Innocent Mangoes, Passionfruits & Apples.

Tesco

Tesco’s Strawberry Sensation is a 750ml smoothie to consider when a larger bottle suits your plans.

  • Its Tesco nutrition listing gives figures per 100ml and per 150ml glass.
  • The listed 15g sugars per 150ml applies to that smoothie, not to every Tesco drink.

Sainsbury’s

Sainsbury’s lists own-label 750ml smoothies alongside branded smoothie options.

  • Its smoothie category includes Mango & Passionfruit and Strawberry & Banana options.
  • A smoothie listing does not establish that the drink is carbonated; check the individual description if you want fizz.

M&S

M&S describes ready-made smoothies made with fruit juice and purées.

  • Its smoothie range is described in 350ml and 750ml bottle formats.
  • Check the particular drink rather than treating the smoothie range as a sparkling one.

Waitrose

Waitrose places Appletiser in its sparkling juice drinks category, providing a clear contrast with smoothie listings.

  • Its Appletiser listing identifies the drink as sparkling apple juice from concentrate.
  • Sparkling juice should not be assumed to contain less sugar than a smoothie; compare equivalent volumes on the labels.

Naked

Naked Blue Machine is listed by Tesco as a 750ml fruit juice drink with added vitamins, rather than a carbonated option.

  • Tesco lists its sugars as 11g per 100ml.
  • Tesco specifies refrigeration and consumption within five days after opening, which matters if the bottle is for several lunches.

Joybuy drinks for the two choices

These options include sparkling fruit drinks for a fizz-led lunch choice and one coconut-milk-and-papaya smoothie for someone seeking a non-sparkling format. Check each pack size against whether you are buying for one break or for later use.

J2O Orange & Passion Fruit 12 x 250ml cans

J2O Orange & Passion Fruit 12 x 250ml

A sparkling soft drink for a lunch choice led by fizz, not fruit-purée texture. The pack contains twelve 250ml cans, so check whether that quantity fits your plans.

De Vina Sparkling White Grape 750ml bottle

De Vina Sparkling White Grape 750ml

A sparkling grape drink rather than a fruit-purée smoothie. Consider how you will portion or share the 750ml bottle; its product information says it contains sulphites and should be refrigerated and consumed within 2–3 days after opening.

De Vina Sparkling Peach 750ml bottle

De Vina Sparkling Peach 750ml

A fizzy peach drink, not a smoothie. The 750ml bottle may need portioning for one lunch; its product information says it contains sulphites and should be refrigerated and consumed within three days after opening.

Nootz Coconut Milk Smoothie Papaya 180ml

Nootz Coconut Milk Smoothie Papaya 180ml

A non-sparkling smoothie option in a 180ml container if you prefer that format to fizz. It contains coconut milk; check the pack for ingredients and dietary suitability. Its nutrition figures use a per-100g basis, which should not be directly compared with other drinks’ per-100ml figures.

De Vina Sparkling Pineapple Coconut 750ml bottle

De Vina Sparkling Pineapple Coconut 750ml

A sparkling pineapple-and-coconut beverage, not a fruit-purée smoothie. Plan how to use the 750ml bottle after opening and check its ingredient label if coconut, soy or wheat matters to you. Its nutrition figures are stated per 100g, not per 100ml.

Frequently asked questions

Are sparkling fruit drinks and smoothies the same thing?

No: the cited UK listings describe smoothies using fruit purée or crushed fruit, while Tesco describes Appletiser as carbonated apple juice from concentrate. Check the individual drink if you want either smoothie texture or fizz.

Does “no added sugar” mean a smoothie contains no sugar?

No. Waitrose says the sugars in its listed Innocent Mangoes, Passionfruits & Apples smoothie occur naturally in the fruit and vegetables, and lists 10g sugars per 100ml. Check the nutrition panel for the amount you intend to drink.

What size should I choose for one lecture lunch?

Choose by the amount you intend to drink, not just the container size. Tesco gives a 150ml glass as the serving on its Strawberry Sensation smoothie listing, while its Appletiser listing gives figures for a 250ml serving. The NHS advises limiting fruit juice and smoothies to 150ml a day and having them with a meal.

Can I keep an opened bottle for another day?

Follow the particular bottle’s storage and after-opening directions. Tesco’s listing for Naked Blue Machine says to keep it refrigerated and consume it within five days after opening; do not apply that period to a different drink.

Should I check the label for ingredients and allergens?

Yes, particularly when an ingredient affects what you can drink. Check the physical pack of the product you choose rather than assuming that a similarly named smoothie or sparkling drink has the same ingredients.
