Who is buying for?

Hosts planning at least 2 litres

If smoothies are the shared drink, plan the total volume across bottles rather than assuming one large bottle will meet the target. Three 750ml bottles provide 2.25 litres.

Shoppers comparing supermarket options

Own-label and branded 750ml smoothies give you different ingredient descriptions and serving information to compare. Check the exact bottles you intend to buy.

Hosts checking ingredients and storage

Read the current ingredient and allergen labels for guests, and make sure chilled bottles can be stored as their labels direct before and after opening.

What should you check?

Decide whether you need smoothie specifically or simply a 2-litre container, then calculate the bottle count and check the labels you will be serving from.

Priority What to check Your needs
Volume Check the volume on each bottle and add the totals: two 750ml bottles give 1.5 litres; three give 2.25 litres. Treat labelled servings as a planning reference, not a prediction of how much guests will pour. I need at least 2 litres of smoothie, so two 750ml bottles would leave me short.
Drink type Read the product description and ingredients. Tesco lists 2-litre juice and juice-drink products separately from smoothies; bottle size alone does not establish the same ingredients or texture. A single 2-litre container would be convenient, but I do not want to substitute juice unless that works for the group.
Ingredients Compare the exact ingredient list and nutrition basis. Sainsbury’s lists 16.5g sugars and 1.2g fibre per 150ml serving for its Mango & Passionfruit Smoothie. I want to know what is in the drink and what the figures mean for the portion being poured.
Chilled storage Check the use-by date, storage temperature and instructions after opening. Sainsbury’s listing for Innocent Mangoes, Apples & Passion Fruits says to refrigerate it at 0–8°C and drink it within four days of opening. I need room to keep the bottles chilled before guests arrive and to store any opened bottles as directed.

Common buying mistakes

  • Choosing a 2-litre juice because the bottle says “smooth”

    “Smooth” can describe juice without making it a smoothie. Tesco’s listed 2-litre smooth orange juice and tropical juice drink are different product types from its listed smoothies.

    Check the product description and full ingredients list; choose juice only if the group is happy with that substitution.

  • Buying two 750ml bottles for a 2-litre plan

    Two bottles provide 1.5 litres, which is 500ml below a 2-litre target.

    If you need at least 2 litres of smoothie, three 750ml bottles provide 2.25 litres. Allow fridge space for them and follow the labels for any leftovers.

  • Counting every smoothie serving separately towards 5 A Day

    The NHS says smoothies can contribute a maximum of one 150ml portion towards 5 A Day per day, even if someone drinks more.

    Use the bottle’s serving information to plan the drinks, but do not present larger pours as additional 5 A Day portions.

  • Leaving opened chilled bottles out

    The Food Standards Agency warns that keeping food for too long or at the wrong temperature can cause food poisoning. The listed Innocent 750ml smoothie specifies refrigeration at 0–8°C and use within four days of opening.

    Keep bottles chilled until serving, use cups for guests, and follow the storage and opened-life instructions on each bottle.

Questions about buying and serving

Should I look for one 2-litre smoothie bottle?

If you need at least 2 litres of smoothie, three 750ml bottles provide 2.25 litres. Tesco, Sainsbury’s, M&S and Waitrose list 750ml smoothie options; if you find a single 2-litre bottle, check its description and ingredients rather than assuming it is a smoothie.

Is 2-litre smooth orange juice the same as a smoothie?

No. Tesco lists 2-litre smooth orange juice and juice drinks separately from smoothies. Read the product description and ingredients if smoothie ingredients and texture matter to your group.

How many 750ml bottles provide about 2 litres?

Buy three if you need at least 2 litres: they provide 2.25 litres, while two provide 1.5 litres. Sainsbury’s labels its 750ml Mango & Passionfruit Smoothie as five 150ml servings per bottle, but guests may pour different amounts.

Does a larger glass of smoothie count as more of my 5 A Day?

No. The NHS says smoothies can count as a maximum of one 150ml portion towards 5 A Day per day, regardless of how much is consumed.

What should I check before serving smoothies to guests?

Check each bottle’s current ingredients and allergen information, use-by date and storage instructions. For example, the Innocent 750ml smoothie listed by Sainsbury’s specifies refrigeration at 0–8°C before and after opening and use within four days of opening.
