WORK IT OUT

My colours are green,red and black 
Come in a bunches and not in a sack 
I make a drink that is alcoholic in taste 
Sometimes I have seeds which are a waste 

My home country is anywhere that's hot 
Eaten with cheese certainly hits the spot 
I finish up in a supermarket for you to pick 
Don't like to be in a box gets on my wick 

One final clue then I'll give you the answer 
I'm eaten by all from doctor to dancer 
Once chosen there is for me no escape 
I am of course dear friend a humble grape
