Oatly Oat Drink Whole and Oatly Barista list rapeseed oil as the third ingredient. If you want a plant drink without seed oils, there are oat, soya, almond and cashew drinks in UK shops that list no oil at all. Many are just water, the main ingredient and salt.

Here is Oatly Oat Drink Whole, from the Oatly UK website:
Water, Oats 10%, Rapeseed Oil, Acidity Regulator (Dipotassium Phosphate), Minerals (Calcium Carbonate, Potassium Iodide), Chicory Root Fibre, Salt, Vitamins (D2, Riboflavin (B2), B12)
The Barista Edition is much the same. It also lists rapeseed oil and dipotassium phosphate.
Oats on their own make a thin drink. Oil makes it creamier. It also helps it act more like cow's milk in tea and coffee.
The acidity regulator (dipotassium phosphate) helps stop the drink from splitting in hot coffee.
Rapeseed oil is allowed in food in the UK. Some people still want to avoid seed oils. That is a personal choice. Our job is to show you the label. For more, read our guide: is rapeseed oil a seed oil?
Yes, but there are not many. Many oat drinks in UK shops list rapeseed or sunflower oil. In our catalogue, we found one oat drink with no oil:

It lists water, oats, a seaweed calcium and salt. It is thinner than Oatly. Shake it well.
Soya drinks don't need oil to be creamy. Soya beans have their own fat. Many plain soya drinks are just water, soya and salt.

See the full list on our plant milks without seed oils page.
Plant drinks can have long lists. Here is what to check:
A short list, like water, oats and salt, has none of these.
Oatly adds vitamins D2, B2 and B12, plus calcium and iodine. Some of the drinks below have calcium added. Most of them do not have added vitamins.
If added vitamins matter to you, check the label. Look for "vitamins" or "minerals" in the list. The drinks with the shortest lists usually have none added.
Yes. Blend oats with cold water, then strain it through a fine cloth. Add a pinch of salt. Don't blend it for too long, or it can turn slimy. It will keep for a few days in the fridge. Shake it before you use it.
A drink without oil may act a bit differently in hot coffee. Here are some tips:
Soya drinks tend to froth best. Almond and cashew drinks are lighter.
Any of these work well in porridge or overnight oats. See our porridge oats and muesli with no added sugar page for oats to go with them.
Does Oatly have seed oil in it? Yes. Oatly lists rapeseed oil. Rapeseed is a seed oil.
Is there an oat milk without rapeseed oil? Yes, a few. In our catalogue, we found one oat drink with no oil. Check the label, as recipes change.
Why do plant drinks have calcium added? Cow's milk has calcium, so many brands add it to plant drinks. It may say calcium carbonate or seaweed calcium.
Which plant drink is closest to cow's milk in coffee? Soya tends to froth best. Drinks without oil can be thinner, so warm them first.
