How much water is in a glass of wine?

It takes 872 gallons of water to produce 1 gallon of wine. Scaled down, it takes about 34 gallons of water for a 5 fluid ounces of wine, according to Huffington Post. But how is this even possible? How come it takes so much water to make wine? What is drought-stricken California doing to conserve water while remaining one of the largest winemaking regions in the world? The water consumption required to cultivate wine includes water used on the vines, water used in the winery and rainwater (crops consume the rainwater). The grapes for the wine require constant irrigation especially in drought-stricken areas such as California and parts of the Mediterranean region. It is important to note that wine grapes require about one-third of the amount of water used to grow almonds, so I guess we should all drink less almond milk and more wine? In the winery, the water use is mostly focused on sanitation. The barrels, tanks, presses and crushers are cleaned and disinfected after every. single. use. Even if the the equipment will be used to make the same type of wine. Wineries are, however, working to use less water. Many wineries, especially in France where crop irrigation is legally regimented, have converted to drip irrigation and today’s advanced technology allows for hoses that can sense when to turn off. Many wineries have adopted onsite water treatment systems so all that water used to clean the equipment can be recycled at the winery. I think it’s safe to say that wine will continue to be consumed all around the world but sustainable technologies and practices must be adopted in order to drink wine guilt free.
