Grapes Juice, lovingly called the "Nectar of Gods" is obtained from crushing grapes and straining the liquid. A common method to make grapes juice at home is as follows:Clean and wash the grapes under running water. Place them in a broad pan and crush the grapes using a potato masher. Strain the liquid using a muslin cloth. Add sugar (according to taste preference) and melt over a slow flame. Boil for two minutes once the sugar has melted. Cool and transfer to glass bottles. Refrigerate and use as required.
