Total investment costs for the wineries in this study ranged from $560,894 for the 2,000 case winery to $2,339,108 for the 20,000 case winery. Building and land costs account for the largest percentage of total investment costs for all wineries. Cooperage accounts for the second largest percentage of total investment cost. The highest percent of variable costs for each winery are packaging costs. Full time labor, cooperage, and purchasing of grapes are the next highest operating costs by percentage. Depreciation of capital assets makes up the highest percentage of fixed costs. Economies of size exist at a decreasing rate among all of the wineries. That is, as the output of the winery increases, the per unit costs of production decline. Average total costs per case decrease from $154.41 for the 2,000 case winery to $124.93 for the 20,000 case winery. The wineries in this study all have the ability to produce positive cash flows by year three, showing that all operating costs and debt obligations can be met. Results show that all wineries have the ability to repay all debt obligations and to operate as self-sustaining entities.
