Hello everybody, I have a question regarding "grapes". The sentence is: This vineyard produces an excellent grape. Is "grape" (singular) totally wrong here, or it just sounds bad? Would it be better like the following? This vineyard produces excellent grapes. There is no context for the sentence, it's just an example for the word "vineyard" in a small dictionary (and yes, I know that "grape" is countable! ). Thanks in advance for your help.
