Grapes on the vine at the Picard family vineyard
Grapes are a fruit from Earth with a sweet taste. Grown in a vineyard, grapes come in red and white varieties. Wine is but one product which is made from grapes.
Groppler Zorn offered William T. Riker a bowl of Earth fruits, including grapes and bananas, when he visited Zorn in the old Bandi City. Riker wanted an apple, but there were none available. The Farpoint Station entity then created a bowl of red apples, as it was instructed to satisfy the desires of the Starfleet crew. This led Riker to suspect the Bandi were not being completely honest about the origins of Farpoint. (TNG: "Encounter at Farpoint")
The Picard family vineyards, located in La Barre, France, grow grapes for wine production. (TNG: "Family", "All Good Things...", et al.)
