About Oatly Creme Fraîche. Luckily for me, I'm gluten intolerant, not coeliac. Oatly products contain less than 100 ppm (mg/kg product) gluten from wheat, rye and barley, meaning they are 'very low gluten'. But they're not 100% gluten free. To be gluten free, products have to have less than 20 ppm (mg/kg product).
If you're in the USA, you'll be able to find gluten free Oatly products. But if you're in the UK or Europe, sadly not yet. If you can tolerate dairy, simply use normal Creme Fraîche for the same result.
