There is no shortage of plant-based milks on the market these days. Recently, oat milk, in particular, has been increasing in popularity, in part because it’s one of the more sustainable plant-based milks out there (one glass of oat milk contributes fewer greenhouse gas emissions than soy or dairy milks, according to research). Whether you like it in smoothies, coffee, baking, or just to drink straight-up, this fast-growing beverage is as versatile as it is tasty. With so many new options on shelves, we’re breaking down the choices to keep you informed and ready for your next grocery trip.
Ahead, find the best oat milks on the market.
Best Overall: OATLY! Oat Drink Organic
Oatly!’s original oat milk is the winner of the batch due to its consistency, color, and texture. This Swedish company, which started out in the 90s, is eco-conscious and remains independent. Keeping with its namesake, Oatly! does, in fact, just sell oat-based products.
According to the brand's website, “The original idea behind Oatly was to find a way to make a nutritious liquid product for people who just didn’t like cow’s milk or were unwilling to use it for personal reasons.” Thirty years later, its products are flying off the shelves, as the oat milk craze catches on (it's also expanded its offerings beyond just milks—you can now find Oatly! ice creams, yogurts, and more). Also noteworthy: Its milk is certified gluten-free and does not curdle when added to coffee—a major bonus.
Best Budget: Dream Oat Beverage Oat Original
Dream’s oat beverage wins the best budget category due to its very reasonable price point. Alternative milks are notoriously pricey compared to cow’s milk, but Dream Oat's price tag is not too far off (and you can probably score an even better deal buying in bulk, as Dream’s beverage is shelf-stable). And for that low price, you’re still getting all the goodness that comes with this nutrient-dense drink. lt sells an unsweetened version as well for those who like a milder flavor.
Best Gluten-Free: OATLY! Low Fat Oat Milk
Oats are naturally gluten-free, but those who have celiac disease or other gluten sensitivities should always check labels for certified gluten-free products to guarantee a product wasn’t processed in a plant where it could’ve been cross-contaminated. Although several oat milk brands claim their products are gluten-free, Oatly!’s products are certified via a third party, which is the gold standard for label claims and certifications.
There is also no added sugar, soy, nuts, thickeners, gums, or GMOs in this milk. This low-fat version is not as thick and creamy as Oatly’s Original, but for those who like the consistency of low-fat or skim milk and are seeking a plant-based alternative, this is a solid choice.
Best High-Protein: Califia Farms Protein Oat Milk
Califia Farms protein oat milk is a nutritional powerhouse, perfect for those not only seeking a tasty plant-based milk but also an extra nutrient-dense boost. This unsweetened milk contains all nine essential amino acids, thanks to pea, oat, and sunflower protein. In addition to protein, this milk is rich in calcium, potassium, vitamin D, and vitamin E, all while tasting delicious and boasting a thick, creamy texture. You can use it as you would any other oat milk—in baking, cereal, smoothies, coffee, or just plain in a glass.
Best Chocolate: OATLY! Chocolate Oat Milk
Who doesn’t love the indulgence of a glass of chocolate milk every once in a while? This childhood favorite has gone vegan-friendly, and now there are plenty of oat-based chocolate milks on the market to satisfy adults and children alike. Our favorite is Oatly!’s chocolate oat milk, which is great on its own but would also work well in baking or smoothies. Cocoa powder and cane sugar provide the sweet chocolaty flavor we know and love. Note that it is higher in calories and sugar than its original milk, as one would expect in a sweet chocolaty treat.
Best Vanilla: Planet Oat Oatmilk Vanilla
For those seeking an indulgent vanilla-infused oat milk, Planet Oat has you covered. Perfect for your cereal, coffee, tea, or smoothies, this milk is as versatile as it is satisfying. It’s also a great find for those who have a sweet tooth but are trying to watch their diet because it is surprisingly low in calories (90 in 1 cup) and sugar (4 grams in 1 cup), so it’s not overly saccharine but rather subtly sweet. It also offers all the other benefits of milk—plenty of vitamin D, calcium, and vitamin A, and it's available in original, extra creamy, and dark chocolate.
Best Clean: Thrive Market Organic Oat Non-Dairy Beverage
Made of just oats and water, Thrive Market’s organic oat beverage has no hidden ingredients. It's perfect for those who are trying to eat clean or minimize processed foods with unpronounceable ingredients and way-too-long ingredient lists. It is unsweetened but does have a natural pleasant sweetness to it, and it can be used in coffee, smoothies, overnight oats, and baked goods. It’s shelf-stable and does not have a weird aftertaste, though it’s on the more watery side, so less ideal for adding to coffee.
Best for Coffee Drinkers: Oatly Oat Milk Barista Edition
Oatly! has winners in several categories and also has a great coffee option, thanks to its popular Barista Edition product that has been specifically created with coffee-drinkers in mind. Whether you work as a barista or make your own coffee at home, this oat milk has a creamier consistency and will even form foam, thanks to an “acidity regulator” in the recipe.
“Just heat this Barista Edition Oat Drink in a container while giving it a whirl until it foams up nicely and then pour yourself a latte," says Oatly!'s site. You can also use this product in tea and cold brew, and it will not separate.
If you’re a purist who would like an all-around winner in terms of taste, texture/consistency, and nutrition while supporting an eco-conscious brand, you can’t go wrong with Oatly!’s Original Oat Milk (view at Amazon). For a more budget-friendly option, we recommend Dream Oat's Original Oat Beverage (view at Walmart). It’s priced pretty closely to cow’s milk, making it a more affordable option if your household goes through a lot of milk.
