If glass is essential, an empty glass container for a homemade smoothie is a more dependable starting point than assuming a ready-to-drink smoothie comes in glass: Ocado lists the sampled Innocent and M&S drinks in plastic bottles. A chilled ready-to-drink smoothie involves less preparation, but whichever route you choose, check the portion, ingredients, sugars and storage instructions; for a container you will carry to work, check its closure and cleaning instructions too.
Making a smoothie and filling a separate glass container lets you prioritise the material. Check that the particular lid, capacity and cleaning method suit your journey and desk routine; a glass container is not automatically suitable for carrying in a bag.
A ready-to-drink chilled smoothie avoids preparation. Before choosing a flavour, compare its stated serving size, sugars per 100ml and per serving, refrigeration instructions and time allowed after opening.
A multi-serving bottle can be divided among colleagues if there is suitable fridge space. Check the number of servings, the opened-life instruction and the exact recipe’s ingredients and allergen information before sharing.
Decide whether glass or a ready-made drink matters more, then compare the amount you will serve and how you will store it at work.
| Priority | What to check | Your needs |
|---|---|---|
| Container material | Check the exact drink’s packaging description, or the material and closure of an empty container. Ocado identifies the sampled Innocent and M&S smoothies as plastic-bottled; GlassBottles.co.uk lists empty glass bottles with selected twist-off closures. | If I specifically want glass, I would rather fill a suitable container myself than judge a ready-made drink by its bottle shape. |
| Portion and sugars | Read the declared serving count and compare sugars on the same basis. Ocado lists 14g per 150ml serving for Innocent Cucumber, Lemon, Apple & Spinach and 18g per 150ml serving for M&S Super Berry; the sampled 750ml bottles each state five servings. | For one desk snack, I want to know how much I will pour, rather than treat a multi-serving bottle as one portion. |
| Cold storage | Check the exact drink’s refrigeration temperature and instructions after opening. Ocado lists 0–8°C for the sampled Innocent drink and 0–5°C for M&S Super Berry; other recipes may have different opened-life instructions. | Can I put the drink in a workplace fridge and finish or share an opened bottle within its labelled period? |
| Ingredients and allergens | Read the current pack’s full ingredient list and allergen declaration for the particular recipe. Front-of-pack fruit imagery and “no added sugar” wording do not replace the nutrition panel. | When buying for colleagues, I want everyone to be able to check the ingredients in the drink they will be offered. |
Ocado identifies the sampled Innocent and M&S ready-to-drink smoothies as packaged in plastic bottles. A bottle-shaped product photo does not establish its material.
Check the packaging description for the exact flavour and size. If glass is essential, consider a separately filled glass container unless the ready-made drink explicitly confirms glass packaging.
The sampled 750ml smoothie bottles state five servings. Their nutrition figures per serving are not figures for the entire bottle.
Compare labels per 100ml and per stated serving, then decide how much to pour or whether to share.
The sampled ready-to-drink products require refrigeration, and instructions after opening differ between products.
Check the label against the fridge facilities at work and your plan for any drink left in the bottle.
A listed capacity and twist-off cap do not, by themselves, establish how a bottle will perform when carried in a work bag.
Check the exact container’s closure, food-contact information, cleaning instructions and any stated transport guidance before using it for a homemade smoothie.
These examples illustrate different drink and container formats; packaging and instructions should be checked on the exact product, not assumed across a brand.
A ready-to-drink chilled smoothie option when avoiding preparation matters more than glass packaging.
The sampled Super Berry Smoothie is a chilled, multi-serving ready-made drink.
Green Machine is another chilled, multi-serving smoothie to compare by its own label.
The sampled Energise Smoothie is a chilled, five-serving drink rather than a confirmed glass-bottled option.

This glass tumbler is an option for drinking a homemade smoothie at a desk. Its lid and straw make it a different format from a capped bottle intended to be carried in a bag.

For a homemade smoothie at your desk, this is a 400ml glass tumbler with a lid and reusable straw, rather than a dedicated capped bottle. Check the lid seal before carrying it in a bag, along with the product’s cleaning instructions.
Do not assume they do: Ocado identifies the sampled Innocent Cucumber, Lemon, Apple & Spinach and M&S Super Berry smoothies as plastic-bottled. If glass is a requirement, check the packaging of the exact drink or choose a suitable empty glass container to fill yourself.
A 250ml or 300ml bottle is a starting point if you want to carry one modest amount of homemade smoothie; GlassBottles.co.uk lists both sizes with twist-off closure options. Choose the capacity for the amount you intend to drink, and check the exact bottle’s closure and cleaning instructions before commuting with it.
No. Check the “of which sugars” line on the exact product’s nutrition panel: Ocado lists 14g per 150ml serving for the sampled Innocent smoothie and 18g per 150ml serving for M&S Super Berry.
Follow its own label and use a suitable fridge. Ocado lists 0–8°C for the sampled Innocent drink and 0–5°C for M&S Super Berry; check the particular product’s instructions for how long to keep it after opening.
Check the current pack’s ingredients, allergen declaration, serving count and storage instructions for the exact recipe. GOV.UK’s allergen guidance for food businesses in England, Northern Ireland and Wales explains the information businesses must provide; do not assume two flavours from the same brand have identical ingredients.
