The tree is definitely unique, but it’s the fruit that makes it worth growing. The grape-shaped nodules that project from the trunk and branches are about 1-2 inches in diameter. Much like the muscadine grapes of the southern regions of North America, the Brazilian grape has larger seeds, usually 1-4 per fruit. When ripe, the grape ranges in color from bright green to purple-black, red-purple, and burgundy-purple. It tastes spicy and slightly acidic.
