The quality and quantity of water available for use is important to the supply of our agricultural raw materials and our ability to operate our business. Water is a limited resource in many parts of the world. If climate patterns change and droughts continue or become more severe or other restrictions on currently available water resources are imposed, there may be a scarcity of water or poor water quality which may affect our and our suppliers' operations, increase production costs, or impose capacity constraints. We are dependent on sufficient amounts of quality water for operation of our breweries, wineries, and distilleries, as well as to irrigate our vineyards and conduct our other operations. The suppliers of the agricultural raw materials we purchase are also dependent upon sufficient supplies of quality water for their vineyards and fields. In addition, water purification and waste treatment infrastructure limitations could increase costs or constrain operations at our production facilities and vineyards. A substantial reduction in water supplies could result in material losses of grape crops and vines or other crops, such as corn, barley, or hops, which could lead to a shortage of our product supply.
We have substantial brewery operations in Mexico and substantial wine operations in the U.S. (primarily in California), New Zealand, and Italy as well as brewery and distillery operations in the U.S. Although certain areas in California have recently experienced flooding, the state has endured and may continue to experience prolonged drought conditions which have resulted in the imposition of certain restrictions on water usage. If these conditions or restrictions persist and/or increase in severity, it could have an adverse effect upon those operations. Our current Mexican breweries are each, and the Veracruz Brewery will be, sourced from a single water supply originating from separate and distinct aquifers. The sources of water, methods of water delivery, water quality, or water requirements to support our ongoing requirements may change materially in the future. We may incur additional expenses for improving water delivery, quality, and efficiency as well as for securing additional water sources.
Our breweries, the Glass Plant, our wineries, and our distilleries use a large volume of agricultural and other raw materials to produce our products. These include corn starch and sugars, malt, hops, fruits, yeast, and water for our breweries; soda ash and silica sand for the Glass Plant; grapes and water for our wineries; and grain and water for our distilleries. Our breweries, wineries, and distilleries all use large amounts of various packaging materials, including glass, aluminum, cardboard, and other paper products. Our production facilities also use electricity, natural gas, and diesel fuel in addition to renewable energy sources in their operations. Certain raw materials and packaging materials are purchased under contracts of varying maturities. The supply, on-time availability, and price of raw, packaging, and other materials, energy, and other commodities have been and may continue to be affected by many factors beyond our control, including economic factors, supply chain disruptions, inflationary pressures, market demand, global geopolitical events and military conflicts, droughts, storms, weather events, or natural or man-made disasters, plant diseases, and theft.
Our breweries, wineries, and distilleries are also dependent upon an adequate supply of glass bottles. At times, we have experienced glass bottle purchasing shortages, particularly for brown glass used for certain of our Mexican beer brands. Glass bottle costs are one of our largest components of cost of product sold. The Glass Plant produces a majority of the total annual glass bottle supply for our Mexican beer brands, and we have a small number of other suppliers of glass bottles for our Mexican beer brands. Meanwhile, we have two aluminum can suppliers that provide all of our total annual requirements for our Mexican beer brands, with one of those suppliers providing a majority of such aluminum can requirements. In the U.S., glass bottles have only a small number of producers. Currently, one producer supplies a majority of our glass container requirements for our U.S. wine and spirits operations.
To the extent any of the foregoing factors impact our business or operations, including by (i) increasing the costs of our products and we are unable or choose not to pass along such rising costs to consumers through increased selling prices, (ii) leading to a shortage of our product supply or inventory levels, or (iii) requiring unplanned diversions of funds, resources, and talent to address such factors, we could experience a material adverse effect on our business, liquidity, financial condition, and/or results of operations.
