Adora seedless grapes, also known as the sugrathirtyfour variety, is a type of seedless black table grape. These berries are seasonally available in late autumn and winter. Adora grapes are purple-black, immensely large in size, meaty, and firm in texture. The thin skin houses a center that is juicy, mild, and sweet with virtually no seed trace. These grapes are often dubbed as the "two-bite grape" due to their large size and rich texture.
