Acai berries have been gaining popularity in the United States as a so-called “superfood” since they first entered the market in the early 2000s.
They are best known as the star ingredient in acai bowls, a type of smoothie that is served in — you guessed it — a bowl, and topped with fresh fruit, granola, and seeds.
But what are acai berries, and what makes them so special? Keep reading to find out!

What are acai berries?
Acai berries are the fruits produced by two particular species of palm trees — Euterpe oleracea and Euterpe precatoria — also known as acai palm (1).
Acai is pronounced “ah-sigh-ee.”
Is acai a fruit?
Acai is a fruit, and despite being referred to as a berry, it is actually a drupe (2).
Drupes (also called stone fruits) are fleshy fruits that contain a single large seed, while berries have lots of smaller seeds.
Other drupes include apricots, cherries, coconuts, dates, mangoes, olives, peaches, and plums (3).
What does acai look like?
Acai berries are small (about 1 centimeter in diameter) and round, with dark purple skin and soft, juicy flesh that surrounds a single large seed in the middle (1).
There is also a less common variety — called white acai — with bright yellow-green skin, but it’s usually not available outside of South America (4).
What does acai taste like?
Acai tastes slightly sweet and tart with an earthy or bitter undertone — its flavor is often described as a cross between blackberries, red wine, and dark chocolate.
It pairs well with other fruits, especially berries and tropical fruits like banana, mango, and kiwi, but can also be used in sauces and dressings for savory dishes.
Where does acai come from?
Acai berries are produced by acai palm trees found in the rainforests of South America (1).
They have served as a major food source for indigenous people there for centuries.
Another popular dish from the Amazon region of Brazil is açaí an tigela, which means “acai in the bowl” in Portuguese.
It is made from frozen acai pulp, blended and sweetened with guarana syrup, then topped with other fruits, nuts, and seeds.
In the United States, acai pulp first arrived in the early 2000’s, and the acai bowl became trendy as a healthy breakfast or snack option.
Today, Brazil is the largest producer and exporter of acai, generating an estimated 9 billion dollars in revenue each year (4).
Where does acai grow?
Acai palm trees are grown almost exclusively in South America, mainly in floodplains along the Amazon River (1).
They look similar to other palm trees, with a slender trunk that grows to an average height of 20 meters, and large, green leaves.
What makes them unique is the clusters — each holding hundreds of acai berries — that branch out from underneath its leaves.
Acai palms are difficult to grow outside of the Amazon rainforest because they require warm, humid weather, consistently moist soil, and partial shade.
However, some plant hobbyists have been able to grow them in tropical environments with proper care.
Interestingly, acai palm trees are also harvested for hearts of palm — a tender, mild-flavored vegetable obtained from the edible inner portion of the tree’s trunk.

How to select
Fresh acai berries are highly perishable, so they aren’t typically available in the United States.
Instead, they can be found in the form of frozen pulp, freeze-dried powder, juice, and premade acai bowls at many supermarkets and health food stores.
1. Frozen acai puree
The most readily available form of acai is frozen pulp that has been pureed and packaged into single-serving packets.
Frozen acai is the best choice for making acai bowls and smoothies, as well as frozen desserts like sorbets and popsicles.
Look for the following frozen acai products in the freezer section of your local supermarket:
- Acai Roots Acai Organic Pouch
- Amafruits Acai Berry Frozen Puree (contains added sugar)
- Explore Superfoods Acai Organic Berry Pulp
- Pitaya Foods Organic Acai Berry Smoothie Packs
- Sambazon Frozen Acai Superfruit Packs
- Tambor Premium Organic Traditional Acai
Note that some acai purees contain added sugar, so read labels carefully.
2. Acai berry powder
Acai powder is made from freeze-dried acai berries that have been processed into a fine powder — it is a very concentrated source of nutrients but has a milder flavor than acai puree.
This form of acai is ideal for adding to baked goods and energy bites but can also be substituted for frozen acai pulp in acai bowls and smoothies.
Check out the following acai berry powder products:
- Feel Good Organics Organic Acai Powder
- KOS Organic Acai Berry Powder
- Navitas Organic Acai Powder
- Pitaya Foods Organic Acai Berry Powder
- Terrasoul Acai Berry Powder
3. Acai berry juice
In its purest form, acai juice is made from pureed acai berries, but most brands add some sweetener or other juices to counteract the bitterness, along with preservatives like citric acid.
Acai juice can be mixed into drinks for a splash of flavor, added to smoothies, whisked into salad dressings and sauces, or even reduced to make acai syrup.
Look for acai juice at your local health food store, or purchase some online here:
4. Premade acai bowls
Most grocery stores carry premade acai bowls in the frozen section for those who need a convenient, on-the-go snack or don’t have access to a blender.
These premade options typically include acai berries blended with other fruits and topped with granola and shredded coconut.
Here are some of the most popular premade acai bowls on the market:
- Dole Acai Bowls (available in 3 flavors: Original, Protein, and Tropical)

These products can be more difficult to find, but are available at certain supermarkets and can sometimes be purchased online:

How to store
Acai berries are stored differently based on which form you’re using.
Store frozen acai puree in the freezer in its original packaging. Most products stay fresh for at least 3 months, but make sure to check the expiration date on the box.
Powdered acai should be kept in an air-tight container and stored out of direct sunlight in a cabinet or pantry. It can stay fresh for up to 2 years.
Unopened acai juice is shelf-stable and should be enjoyed by the best-by date printed on the bottle. After opening, store acai juice in the refrigerator and use within 7-10 days.
For other acai products, check the packaging for storage instructions.
