These are the types of grapes used in making wine. These grapes are smaller than table/eating grapes. Each type is used for different wine varieties.
Here you can see the grapes for Cabernet Sauvignon, Pinot Noir, Sauvignon Blanc, Merlot, Chardonnay.
My favourite wine variety is White Riesling not shown here.
Many thanks to my friend for lending me this photo.
