The fruit, commonly known as açaí berry, is a small, round, black-purple drupe about 1 inch (25 mm) in circumference, similar in appearance but smaller than a grape and with less pulp, and produced in branched panicles of 500 to 900 fruits. The exocarp of the ripe fruits is a deep purple color, or green, depending on the kind of açaí and its maturity. The mesocarp is pulpy and thin, with a consistent thickness of 1 mm or less. It surrounds the voluminous and hard endocarp, which contains a single large seed about 0.25–0.40 inches (7–10 mm) in diameter. The seed makes up about 80% of the fruit (Schauss, 2006c). Two crops of fruit are produced each year. The fruits can be harvested and consumed.
