Oatly Barista 1.5L

it's micro-foamable!
Oatly took inspiration from their normal sized US-packs and made an extra-large pack for all true baristas, pretend-baristas and other coffee lovers who likes their rich, creamy, and micro-foamable oats in abundance. The neutral taste comes from a combination of premium oats and unsaturated fat that will make any hot drink, like coffee, tea, or hot chocolate, seem like it's undergone some kind of upgrading process.

For the pros (and non-pros too):
The acidity regulator Oatly uses is to help the Oat Drink Barista Edition perform to the professional expectations of coffee experts, so it should answer your needs, too, even if you happen to be more of a breakfast brewer. Oatly put the same vitamins and minerals in the Barista as in their other oat drinks, something they thought you might appreciate. It can be stored for a long time before opening. No dairy, no nuts, no soy, and no separating in the coffee.

Water, OATS 10%, rapeseed oil, acidity regulator (dipotassium phosphate), minerals (calcium carbonate, potassium iodide), salt, vitamins (D2, riboflavin, B12).
