The custom of blessing grapes, the first fruits of the harvest, can be traced back to Old Testament times when farming was a common vocation and much care and time was given to it. Of the vast variety of produce, grapes had a special place of honour and were considered the “first fruits”, because they were the first produce of harvest.
It is traditional to use seedless grapes for the Blessing to emphasise that this fruit came into being without seed just as Christ became man without any human agent.
