This process is called photosynthesis. It happens in every green plant. Without it plants could not make the food they need to live, and we would not have food to eat or wine to drink.

The grapes will get bigger and in a few more months it will be autumn and the fully-grown grapes will turn purple and be ready to harvest. The leaves will turn a lovely red and gold.  Then suddenly it will get cold, signaling the arrival of winter, and the leaves will turn brown and die, leaving only the brown branches of the vine.
