Sour Grape is a pungent hybrid strain created by crossing Sour Diesel and Granddaddy Purple. It has a sour, fuel-like scent with fruity aftertones and a mouth-watering flavour of sweet yet sour grapes.0 It is an evenly-balanced strain with a smooth and rich smoke that leaves a sweet treat lingering on the palate. It is primarily purple with bundles of fiery-orange pistils, and only about 10% of the buds' surface area is made up of green leaves. Sour Grape is rich in diesel fumes and has undertones of fruity berries.1 It is known for its introspective and relaxing effects, relaxing the muscles while avoiding strong sedative effects.
