For a picnic without reliable cooling, choose an oat drink whose unopened carton is labelled for ambient storage; a chilled drink needs to stay cool. If total fat matters, compare nutrition figures on the same basis before choosing: Alpro lists 1.5g per 100ml for Oat No Sugars, while M&S lists 0.5g per 100g for Only 3 Ingredients, which is chilled and unfortified. Check the carton’s storage and allergen instructions before packing or serving it.
If lower total fat is a priority for lunch, read the nutrition panel rather than assuming all oat drinks have the same fat content. Check the unit as well as the number: a figure per 100g is not directly interchangeable with one per 100ml.
Look for an unopened carton whose own instructions permit ambient storage. If you choose a chilled drink, plan how to keep it cool alongside the other picnic food that normally stays in the fridge.
Read the particular carton for fortification, ingredients, allergens and gluten-related suitability. A dairy-free description does not answer every allergy or coeliac question.
Start with the carton’s storage instructions for your picnic, then compare nutrition figures and suitability statements for the people drinking it.
| Priority | What to check | Your needs |
|---|---|---|
| Total fat | Read total fat and its stated unit on each nutrition panel. Compare figures on a consistent per-100ml basis where the labels allow it; do not treat per-100g and per-100ml figures as identical. | I’m looking for a lower-fat drink for lunch, so I need to compare the actual cartons rather than choose by the word “oat”. |
| Storage | Check whether the unopened carton is ambient or chilled, then read its instructions for after opening. The Food Standards Agency advises keeping picnic food that normally needs refrigeration cool. | Without dependable cooling, I need a carton labelled for storage outside the fridge before opening. If I take a chilled drink, I need a way to keep it cool. |
| Fortification | Check the label for added calcium, iodine and vitamins if those ingredients matter to your choice. M&S says its Only 3 Ingredients Oat Drink is not fortified; Alpro lists calcium and iodine for Oat No Sugars. | I want to know what is added to this particular drink, not assume that a shorter ingredient list or a lower fat figure tells me. |
| Allergens and suitability | Read the current ingredient and allergen statements, including any gluten-free or coeliac suitability wording. The Food Standards Agency notes that oats remain an allergen even in food labelled gluten-free. | If I’m serving someone with an allergy or a coeliac requirement, I need to check the exact carton before it goes into the picnic bag. |
Product figures differ, and a serving-sized value can obscure the basis of comparison. M&S lists 0.5g per 100g for Only 3 Ingredients, while Minor Figures lists 4.3g per 200ml for Barista Oat; those units should not be read as though they match.
Check total fat and the unit on each carton. Use like-for-like nutrition figures when making a lower-fat choice.
Oatly says its chilled Semi must not be stored at room temperature. The Food Standards Agency advises keeping foods normally refrigerated at home cool during a picnic.
Pack chilled food in a cool bag or cool box with ice or frozen gel packs, and take the drink out when it is needed.
Oats remain an allergen even when a product is labelled gluten-free. M&S also states that its Only 3 Ingredients Oat Drink is not suitable for people with coeliac disease or wheat allergy.
Check the physical carton’s ingredients, allergen emphasis and product-specific suitability statement before serving others.
M&S states that its Only 3 Ingredients Oat Drink is not fortified, whereas Alpro lists added nutrients for Oat No Sugars. Ingredient simplicity and fortification answer different buying questions.
Decide whether fortification matters for this purchase, then check the particular drink’s label alongside its fat and storage information.
A brand name alone does not settle the picnic choice: storage, nutrition and suitability can differ between drinks in the same range.
Alpro lists Oat No Sugars at 1.5g fat and 0g sugars per 100ml. Tesco describes its long-life version as UHT sterilised.
Oatly describes both ambient and chilled versions of Oat Drink Semi, each stated at 1.5% fat.
Tesco lists Long Life Oat Original in a 1L UHT format, with 1.6g fat per 100ml.
M&S lists 0.5g fat per 100g for its chilled Only 3 Ingredients Oat Drink and 1.5g per 100g for its Semi Oat Drink.
Minor Figures positions Barista Oat for coffee and lists 4.3g fat per 200ml serving.
These oat-drink listings include long-life options and a barista variant. Check each product’s current nutrition panel and storage instructions against your picnic plan; the titles alone do not establish a like-for-like fat comparison.

This long-life barista variant is worth checking if the picnic includes coffee. The listing is for 8 x 1L; compare the carton’s total fat with other drinks on the same basis and follow its storage instructions.
Yes, if you can keep it cool. The Food Standards Agency advises keeping picnic foods that normally stay in the fridge cool, so use a cool bag or cool box with ice or frozen gel packs and take the drink out when needed.
An unopened carton labelled for ambient storage is more practical when you cannot keep a chilled drink cool. Oatly says its ambient Semi can be stored at room temperature before opening, while its chilled Semi cannot; follow the particular carton’s instructions after opening.
No. Total fat and sugars are separate entries on the nutrition panel. Alpro lists 1.5g fat and 0g sugars per 100ml for Oat No Sugars; check both figures on any other drink you are considering.
No; suitability depends on the particular product. Check its gluten-free and coeliac statements before serving it. M&S says its Only 3 Ingredients Oat Drink is not suitable for people with coeliac disease, and the Food Standards Agency notes that oats remain an allergen even in food labelled gluten-free.
No. Alpro lists calcium and iodine for Oat No Sugars, while M&S says its Only 3 Ingredients Oat Drink is not fortified. Check the individual carton if added nutrients matter to your choice.
