A new distinct variety of grapevine named ‘ARRAEIGHTEEN’ abundantly forms attractive large berries having deep blue/black skin coloration in medium clusters. The fruit displays a naturally sweet flavor and is juicy and meaty in texture. The fruit commonly is ready for harvesting during July in San Joaquin Valley of Central California, U.S.A, and displays good eating qualities as a table grape. The fruit firmness renders the fruit well amenable for handling, shipping, and storage.
