1-WHY ARE STANDARD WINE BOTTLE SIZES 0.75-LITER? We don’t have one definitive answer to this one but instead 3 theories to share: - In order to optimize production, glassmakers made the bottles according to the minimum amount of glass-blowing necessary which first produced a 0.75-liter bottle - One 0.75-liter bottle of wine contains 6 0.125-liter glasses of wine. This is the standard for Italian Osteria restaurants. - The English measured wine by the gallon, and every case of wine could contain a maximum of 2 gallons. This is the equivalent o 12 0.75-liter bottles of wine. 2-CAN YOU MAKE WHITE WITH RED GRAPES? Yes, you can! The color of red wine comes from the grape skin. The pulp instead is practically colorless. If the red grape skin is removed from the pulp during the process of winemaking, it is indeed possible to make white wine from red grapes. 3- HOW MANY GRAPES DOES IT TAKE TO MAKE ONE BOTTLE OF WINE? On average it takes 2.5 pounds of grapes to make a standard bottle of 0.75-liter wine.
