We are having an open bar at the reception and we are purchasing the alcohol and other colas, tonic water, orange juice and club soda for the bar area. We have invited 225 guest and hired three bartenders. We have purchased gin, rum, vodka, brandy, scotch (about 5 liter bottles each brand, i.e, evans and williams, barcardi, paul masson, etc). Is this enough to serve my guests or should have have at least 10 bottles each brand? I want everyone to have at least two drinks.
