Oat milk
Mildly sweet and creamy with a subtle oat flavor and a thicker mouthfeel than most nut milks.
Lens analyzedOat milk is a plant-based milk alternative made by blending oats with water and straining out the solids, leaving a naturally sweet, creamy liquid. It froths well, which has made it popular in coffee drinks alongside its use as a dairy substitute in cereal and baking. Its texture tends to be thicker than almond or soy milk.
Where it comes from
Oat milk was developed in Sweden in the 1990s as researchers looked for a plant-based milk alternative that didn't rely on soy or nuts, later growing into a major category across North American grocery stores. Its rise tracked alongside broader interest in dairy-free alternatives over the past couple of decades.
Buying it
Check whether a carton is labeled 'barista' if you want one formulated to froth well in coffee. Compare added sugar between brands, since some are sweetened and others are plain.
Storing it
Refrigerate oat milk once opened, where it keeps for about ten days; shelf-stable cartons can sit in the pantry unopened until their printed date.
Keeps about 10 days in the fridge.
