The original V8 is a savory juice. It is made mainly from water and tomato concentrate, and reconstituted vegetable juice blend: water and concentrate of eight vegetables, specifically: beets, celery, carrots, lettuce, parsley, watercress, spinach, and tomato. Campbell's has produced several varieties of the drink, such as Original, Spicy Hot, Hint of Black Pepper, Lemon, Picante, Low-Sodium, and Organic.

Three spin-offs of the V8 brand, "V8 Energy", "V8 Splash" and "V8 V•Fusion", are blends of fruit and vegetable (specifically carrot) juices. V8 Splash is a juice cocktail partially sweetened with high-fructose corn syrup and sucralose; diet versions of V8 Splash omit the high-fructose corn syrup. V8 Energy also classifies as a cocktail and is partially sweetened with sucralose. V•Fusion is made from 100% juice.
