What's the difference between all these oat milk brands?

How different can they be?

Goodmylk sells frozen oat milk concentrate that can be diluted with water at home.


Oat milk’s star is rising. In September 2020, it officially overtook soy – considered by many to be the original alt-milk – and settled comfortably into the second-top-selling spot in the US plant-based milk category.

While almond milks dominate 63% of the US plant-based milk market, sales of oat milk have risen a whopping 303.7% year-on-year, according to market research firm SPINS.

Data from Glimpse, a trend forecaster that analyses search and social media platforms, also reflects a significant uptick in oat milk interest in 2020.

It’s a staggering shift in consumption habits considering Oatly only made its US debut five years ago. And as for 2021, rumour has it we may witness the world’s first oat milk IPO, as Oatly reportedly gears up for a stock listing in the first half of this year. Whatever you think of its investors, a market debut of this nature would be a watershed moment for brands that have built identities around sustainability.

The popularity of oat milk among vegan, vegetarian and flexitarian consumers has given rise to a number of new product launches in the space, with each brand presenting its idea of what makes their oat milk just right. So what’s the difference between them? Five brands offer their explanations.
