1 Site and Soil Parameters for Northern Grape Production New England Vegetable and Fruit Conference 2015 Statewide Viticulture Extension

2 Northern Grapes : Integrating viticulture, winemaking, and marketing of new cold hardy cultivars supporting new and growing rural wineries 5 Year Coordinated Ag Project 12 Institutions, 12 states 34 Research/Extension Scientists 23 Industry Associations $2.5M Funded (2 yr) USDA; $3M Renewal (2 yr) Matched > 25 Organizations and Individuals The Northern Grapes Project is funded by the USDA s Specialty Crops Research Initiative Program of the National Institute for Food and Agriculture, Project #

3 Multi-Disciplinary Studies Address Varietal performance and resulting fruit and wine flavor attributes in different climates Applying appropriate viticultural practices to achieve consistent fruit characteristics for ripening Applying winemaking practices to their unique fruit composition to produce distinctive wines that consumers will like and purchase Understanding consumer preferences, individual/regional marketing strategies to increase sales and sustained profitability of wineries and vineyards. The Vine The Vineyard The Wines The Tasting Room

8 Main points Site selection is an economic decision Five key points about site selection Climate trumps soil Air drainage is EXTREMELY important Many Northern Grape cultivars prone to early budburst (V. riparia heritage) Well drained soils are important Soil attributes can be improved before planting

9 Economics: Grapes and Wine How much land does it take to grow wine? 3000 case winery = 7200 gallons of wine 60 cases per ton = 50 Tons of grapes At 3.5 T/acre =14 acres of grapes If you grow grapes + make/sell wine How much land does it take to make money growing grapes? Machinery + Land + development costs Probably >> 14 acres

10 Vineyard Development Costs How much $$ to develop a vineyard $18,792 per acre to Yr 4 (2010) $9,897 per acre in machinery & equipment (assuming costs spread over 50 acres) $28,609 K total investment per acre. 50 acres = $ 1,430,450

11 Investment Machinery/equipment $151,825 Buildings $69,000 Total $220,850 Investment per acre 20 acre vineyard Land $5,400 Machinery/Equipment $7,591 Buildings $3,450 Vineyard development $18,792 Total per acre $35, acre = $704,660 investment

12 Economic Impact of Site Selection Over 25 year lifespan of vineyard: Each 0.1 T/acre in additional yield = $900 Net Present Value ($1200/T) You can afford to spend more on an excellent site A poor site costs you money Source: G. White, Dept Applied Economics and Management, Cornell University

13 Site selection and pre-plant site preparation Climate- Large scale, regional Climate- micro scale Soils and site preparation Not Changeable Can be Modified Major Theme: Pay now or pay later! Good sites and preparation pay off Poor site selection and preparation cost money
