The table below shows how per case wine cost depends upon the cost of the grapes. When less expensive grapes are used, the cost of the package is the major cost factor. Obviously, these estimates do not include the original cost of winemaking equipment, and they do not include the cost of repairs, yearly maintenance, etc. The cost of homemade wine depends on the cost of the grapes and the cost of the package. Home winemakers can reduce their winemaking costs by purchasing grapes by the ton and supplies in commercial quantities.
Washing used wine bottles is another way to reduce home winemaking costs.
