There are many variables that will impact costs, from vine spacing to the price of steel on any given day. However, the basic materials necessary for building a vineyard are similar no matter where you are. Vineyard economics are built into the the vineyard business plan, which is a dynamic document that acts as a road map for development, but the route can change over time. It is important to decide on a comfortable overall budget for the project and try to stay within its limits. Vineyards are notorious for being more expensive than spreadsheets often reveal. Like building a house, there are often unexpected contigencies that can drastically affect costs. Developing the business plan and budget should be done during the education-discovery phase of planning a vineyard. Informational materials should be supplemented with real-life experience which can be found in fellow grape growers. They have written the checks and know how much it costs. There are a number of excellent publications, guides and calculators that can provide an overview of expenses associated with developing a vineyard:
