Pastry Stouts (or Dessert Stouts) and New England-style IPAs often utilize lactose, or even milk, as an ingredient to lend a creamy mouthfeel to beer. As a vegan myself, this is a fact that can be difficult to deal with at times. Thankfully, Dogfish Head’s Sam Calagione has a new solution: oat milk.

Dogfish Head is known for blazing trails in craft beer. And that’s especially true when it comes to IPAs (continuous hopping and Imperial IPAs can be attributed to Sam’s ingenuity). But oat milk? Oats and oatmeal have been putting in beers for a while now, but oat milk is different, and Dogfish Head’s new beer Hazy-O!, released in Dogfish Head’s home state of Delaware on October 2 and available nationwide in early 2021, is one of the first beers to take a swing at it. It may be a game-changer.

Plenty of studies have shown that our diets, specifically meat and dairy, have played a large part in climate change. A report from the Yale Program on Climate Change Communication earlier this year stated: “The production of livestock generates the highest levels of greenhouse gas emissions, whereas the production of fruit and vegetables generates the lowest levels.”

Plant-based diets, of which oat milk squarely fits into, are one of the smartest choices we can make to have as little impact on the environment as possible. And oat milk has one of the smallest carbon footprints of any milk alternative — it’s also one of the easiest to make yourself at home.
