Best Overall: OATLY! Oat Drink Organic

OATLY! Original OatMilk

Oat milk is having a moment. With plenty of people tired of additive-laden soy milk and sometimes-watery almond milk, oat milk is the new plant-based beverage on the block that boasts a creamy texture, plus an allergen-free profile. Just take this original oat milk from Oatly.

Oatly was one of the first brands to bring oat milk to a coffee shop near you. Now the company’s signature cartons can be found in kitchens across the country—if you can get your hands on it. Consumers have been known to buy out Oatly’s online offerings. Most people love Oatly’s original oat milk for its smooth texture and rich flavor. Best of all, it’s naturally sweet, with no added sugars. 

Best Budget: Silk Oat Yeah Oatmilk The Vanilla One

Silk Oat Yeah Oatmilk The Vanilla One

Widely available and more affordable than other options on the market, Silk’s vanilla oat milk serves up satisfying sweetness. Though this option does contain added sugars, it’s not sky-high in the sweet stuff. Each serving delivers 6 grams of total sugar. To keep your added sugar intake in check, just add a touch to your a.m. coffee.

If you’re looking for a minimalist ingredient list, Silk may not be for you. The package lists a handful of less-than-ideal ingredients, including cane sugar, sunflower oil, and “natural flavors.” Sunflower oil is high in omega-6 fatty acids, which may increase inflammation in the body, while the term “natural flavors” is basically a catchall term that can include highly processed ingredients. 

If you’re all about flavor, rest assured you’ll like this milk. Silk sippers say the vanilla oat milk tastes delicious and doesn’t feel as heavy as whole milk. It’s also a great addition to smoothies or homemade “nice cream.” Yum.

Best Ingredients: Thrive Market Organic Oat Non-Dairy Beverage

Thrive Market Organic Oat Beverage

Thrive Market wins the award for best ingredient list on the oat milk market. The dairy-free beverage is made from water and oats, nothing else. Also important: Thrive’s blend is made exclusively from organic oats, which is actually pretty important these days. Why? Oats are among the crops most commonly treated with glyphosate, a highly controversial weed killer. Though the US Environmental Protection Agency maintains that glyphosate is safe, the World Health Organization calls the pesticide “probably carcinogenic” and a recent study reported that exposure to glyphosate could increase cancer risk by more than 40%.

The bottom line: when it comes to buying oats and oat-based products, opt for organic if you can. Tests show that organic oats contain far lower levels of glyphosate residue compared to conventional oats.

Best Low-Fat: Pacific Foods Organic Oat Original Plant-Based Beverage

This soy-free and vegan oat beverage from Pacific Foods offers just two grams of fat per 1-cup serving, less than most options on the market. Reviewers love the versatility of this organic formula from Pacific Foods. Use it to make dairy-free hot chocolate, lattes, smoothies, pancakes, or oatmeal. 

One note: though there is no sugar added to this blend, each serving is high in natural sugar, with one cup offering up 17 grams. The high sugar content results when whole oats get broken down into simple sugars. Avoid guzzling the stuff, especially if you’re insulin resistant or watching your carb intake.

Best Tasting: Califia Farms Oat Barista Blend Milk

Because oat milk seems to be everyone’s favorite add-on at their coffee shop, brands have crafted barista-friendly versions of their classic oat milks. These blends tend to contain dipotassium phosphate, a salt that aids in frothing. The result is an ultra foamy, seriously satisfying consistency that elevates your coffee stat.

This barista blend from Califia Farms often tops customers’ lists for the best tasting oat milk on the market. It’s super creamy and froths perfectly, plus it’s made from relatively few ingredients and zero added sugars. Reviewers love its mild flavor and creamy texture, with some even comparing its consistency to half and half (minus the saturated fat, of course). Whether you’re sipping it in coffee, smoothies, or using it for cereal, you’re sure to love this oat milk’s decadent taste.

Best Gluten-Free: Califia Farms Unsweetened Oat Milk

Califia Farms Unsweetened Oat Milk

Yes, oats are naturally free from gluten. But most oats get processed in the same facilities as gluten-containing grains, like wheat, barley, and rye. As a result, oats are often subject to contamination. If you suffer from celiac disease or severe gluten intolerance, be sure to choose oats that are certified gluten-free, like the ones used in this unsweetened oat milk from Califia Farms. 

Califia customers love that this option contains no gums, no stabilizers, and no gluten. Each serving contains only 2 grams of natural sugar and 9 grams of carbohydrates, far fewer than most grain-based milks on the market.

Best for Coffee: Oatly Oat Milk Barista Edition

If you’re a fan of foam, Oatly’s barista edition oat milk is bound to be your jam. Formulated to froth, this perfectly foam-able oat milk is best used for coffee-based beverages. Simply steam some for your brewed coffee or get fancy and use it to make a DIY latte. It all works.

The oats used in Oatly’s barista edition oat milk are certified gluten-free and the blend is fortified with nutrients such as riboflavin, and vitamins B12 and D. Each serving delivers 7 grams of fat (Oatly adds rapeseed oil to this milk), 3 grams of protein, and zero added sugars. One cup contains 140 calories. Customers love it so much that reviews on Oatly’s website are mostly made of love letters to the barista blend...and requests that the oat milk be made more widely available. Grab a carton (or four) while you can!

Best Chocolate Oat Milk: Planet Oat Oatmilk Dark Chocolate

Planet Oat Dark Chocolate Oatmilk

Does chocolate milk bring you back to your youth? You’re not alone. The creamy sip is undeniably reminiscent of childhood. That’s why we like to think of this oat milk from Planet Oat as chocolate milk, all grown up. Made from non-GMO ingredients and free from artificial colors, flavors, and preservatives, this isn’t exactly like the Nesquik you used to drink.

Still, Planet Oat’s chocolate oat milk is definitely more energy-dense than other oat milk options: there are 140 calories and 12 grams of sugar (8 added, 4 natural) in every 1-cup serving. Cocoa powder and cane sugar lend the beverage its signature sweetness. Use the decadent dairy-free beverage as a substitute for regular milk while baking, or mix it into a chocolate smoothie as an occasional treat.
