Did you know?

Oat milk was invented in 1994 by Swedish scientist Rickard Öste who was researching sustainable food production alternatives to dairy. He founded Oatly in 1996. Oat milk produces approximately 80% less greenhouse gas emissions than dairy milk and uses significantly less land and water. The rise of oat milk as a coffee shop staple is largely attributed to its ability to froth well without separating — a property that makes it popular for lattes. For dogs this elaborate origin story is irrelevant — tiny amounts of plain oat milk are simply a lactose-free liquid with minimal nutritional value.
