Families packing several lunches
If several people will share a carton, work out how much they are likely to drink before deciding how many 1L cartons to take. Plan to keep any opened remainder chilled.
Who is this for?
Families comparing added nutrients
Check the nutrition panel if calcium, iodine or added vitamins matter to your choice. Alpro and Sainsbury’s list fortified oat drinks, while M&S describes its Only 3 Ingredients Oat Drink as unfortified; those descriptions do not apply to every product from each brand.
Families checking allergens
Read the label of the carton you will serve, particularly where gluten or wheat is a concern. Minor Figures labels Everyday Oat gluten free; M&S says its Only 3 Ingredients Oat Drink is not suitable for people with coeliac disease or a wheat allergy.
What should you check?
Decide how much drink the picnic needs, then check storage and the exact carton label before choosing between a single carton, a case or a chilled product.
| Priority | What to check | Your needs |
|---|---|---|
| Storage | Read the unopened-carton storage instructions. Keep chilled drinks and opened cartons cool in a cool bag or box with ice or frozen gel packs, as the Food Standards Agency advises for foods normally kept refrigerated. | I want to pack the drink before leaving without losing track of what needs chilling once it has been opened. |
| Pack size | Compare the number of 1L cartons in a case with the number you expect to open. Check the carton’s instructions for refrigerating leftovers. | We may use one carton at this picnic, even if a multi-pack suits several outings. |
| Nutrition label | Compare listed nutrients per 100ml and distinguish “no added sugars” from “no sugars”. Check age guidance when choosing a drink for a young child. | I want the carton’s nutrient information to fit its role in our usual meals, rather than choosing by the ingredient count alone. |
| Allergens | Read the current gluten, wheat and other allergen statements on the exact product. An oat-drink name alone does not establish suitability for someone with an allergy or coeliac disease. | Someone sharing the picnic needs a clearly labelled option that meets their requirements. |
Picnic packing mistakes
-
Treating a family pack as individual portions
A case contains separate cartons, but each 1L carton may be more than a small group will finish at lunch.
Estimate how much the group will drink and take only the cartons you expect to open. If you expect leftovers, plan how to chill them.
-
Assuming every oat drink is gluten free
Product labels differ: Minor Figures calls Everyday Oat gluten free, while M&S says its Only 3 Ingredients Oat Drink is unsuitable for people with coeliac disease or a wheat allergy.
Check the current carton’s full allergen statement before serving someone with a relevant dietary restriction.
-
Equating a short ingredient list with fortification
M&S describes its three-ingredient oat drink as unfortified. Other oat drinks list added nutrients, so the recipes are not interchangeable on that basis.
Compare the nutrition panels if fortification matters to the choice, and read any age guidance on the product.
-
Leaving chilled drinks or opened cartons in the sun
The Food Standards Agency advises keeping foods normally refrigerated cool on a picnic and out of direct sunlight; warm exposure increases food-safety risk.
Use a cool bag or box with ice or frozen gel packs for chilled drinks and opened cartons, and follow the carton’s post-opening instructions.
Brand and product references
Alpro
Alpro UK lists distinct 1L oat drinks, including Oat Original and Oat No Sugars.
- Alpro lists added calcium and vitamins for Oat Original. Its Oat No Sugars nutrition table states 0.0g sugars per 100ml.
- The no-sugars figure belongs to Oat No Sugars, not every Alpro oat drink. Check the chosen carton’s storage and allergen instructions.
Minor Figures
Minor Figures sells Everyday Oat as a 6 x 1L case for households that expect to use several cartons over time.
- The Everyday Oat product page labels this drink gluten free and lists added calcium and vitamins.
- A six-carton case is household stock, not six individual picnic portions; check the label before serving anyone with an allergy.
Sainsbury’s
Sainsbury’s Long Life Oat Drink is a 1L UHT option with stated pre-opening and post-opening storage instructions.
- Sainsbury’s lists added calcium, iodine, vitamin D and vitamin B12, and says to store the unopened carton in a cool, dry place away from sunlight.
- Its product instructions say to refrigerate after opening and use within 3 days. Read the carton’s allergen and age guidance before serving it.
M&S
M&S has differently formulated oat drinks: Only 3 Ingredients Oat Drink and Plant Kitchen Whole Oat Drink should not be treated as the same product.
- M&S lists water, oats and sea salt for Only 3 Ingredients Oat Drink. The Plant Kitchen Whole Oat Drink listing describes added calcium, iodine and vitamins.
- M&S says the three-ingredient drink is unfortified and unsuitable for people with coeliac disease or a wheat allergy. Check each product’s own storage instructions.
Oatly
Oatly has distinct chilled, long-life and barista-labelled oat drinks; choose by the exact variant rather than the brand name alone.
- Tesco Groceries lists both chilled and long-life Oatly 1L variants. Oatly describes its Barista Organic drink for use in coffee and tea.
- Oatly notes that ingredients can differ between markets, so check the UK carton’s ingredients, nutrition and storage information.

The eight 1L cartons suit a household planning to take separate cartons on several outings, rather than individual portions for one picnic.

Oatly Long Life Barista Oat Drink, 6 x 1L
This case gives you six separate 1L cartons if the family will use oat drink across several picnics or for drinks at home.
The variant is labelled long life and barista. Check the exact carton’s nutrient, allergen and post-opening storage information before packing it.

Alpro Oat Original Long Life Drink, 8 x 1L
The eight-carton case suits repeated use; take a 1L carton to the picnic only when its contents are likely to be used or leftovers can be chilled.

No image available
Alpro Barista Oat Long Life Drink, 8 x 1L
This barista-labelled case offers eight separate 1L cartons for a household planning more than one outing.
Do not assume it has the same nutrient profile as Alpro Oat Original or Oat No Sugars. Read this variant’s carton for ingredients, allergens and storage after opening.

Oatly Organic Barista Oat Drink, 6 x 1L
The six 1L cartons provide separate drinks to take as needed across outings, rather than single-serving picnic packs.
Check this Organic Barista variant’s carton for pre-opening storage, added nutrients, allergens and how to handle it after opening; do not apply another Oatly variant’s instructions to it.
Picnic oat-drink questions
Does oat drink need to go in the picnic cool bag?
A chilled oat drink or an opened carton needs to be kept cool; follow the exact product’s storage instructions. An unopened long-life carton can be stored as its label directs: Sainsbury’s, for example, specifies a cool, dry place away from sunlight before opening. The Food Standards Agency advises using a cool bag or box with ice or frozen gel packs for foods normally kept refrigerated.
Can I keep an opened carton after the picnic?
Keep it only if it has remained appropriately chilled and you can follow its post-opening instructions. Sainsbury’s says to refrigerate its Long Life Oat Drink after opening and use it within 3 days. The Food Standards Agency advises keeping foods normally refrigerated cool throughout a picnic, so do not rely on the stated number of days if the carton has been left warm.
Is every oat drink suitable for someone with coeliac disease?
No. Minor Figures labels Everyday Oat gluten free, while M&S says its Only 3 Ingredients Oat Drink is not suitable for people with coeliac disease or a wheat allergy. Read the current label of the exact carton you intend to serve.
Can a simple-ingredient oat drink replace milk for a young child?
Do not assume that it can. M&S states that its unfortified Only 3 Ingredients Oat Drink is not recommended as a dairy replacement for children under 36 months. Check the chosen drink’s nutrient information and age guidance; seek appropriate professional advice about an individual child’s diet.
