Second Year Pre-Plant: Variety Selection

Many factors come into consideration when you are trying to decide what varieties to plant in your vineyard. For example, if you are located in a region that has a glut of a particular variety, then, obviously, you don't want to plant or market that variety. The best option is to begin with small plantings of one to five varieties, ideally not more than an acre of each.

Once you think you know what you would like or would be able to market, the next step is to use your site to dictate what you can grow. Site selection is key in determining what varieties you'll plant, so make sure you are armed with information on winter lows, precipitation, and growing degree days.

It is also important to consider what levels of disease resistance you prefer in your varieties, as this will affect your vineyard pest and disease management techniques, not only the year of planting, but also in subsequent seasons as well, especially if you plan to use sustainable practices (scouting, weather information, etc.).

Although there are a few muscadine wines produced in New York, it is more common in southern states, where the muscadine vines thrive. These pages focus primarily on the three types of grape commonly used in commercial wine production in New York State:

Native varieties (Vitis labrusca)

• Good cold hardiness
• Productive on own roots
• Examples:
  • Concord
  • Niagara
  • Catawba

Interspecific/French American hybrids

• More resistant to winter injury than V. vinifera
• Greater tonnage than V. vinifera
• Examples:
  • Seyval
  • Vidal
  • Noiret

Vitis vinifera

• High quality fruit and wines
• Must be grafted to rootstock
• Susceptible to winter injury
• Examples:
  • Cabernet Sauvignon
  • Riesling
  • Pinot Noir

There are several considerations when selecting a variety - or varieties - to plant.

Market

• Are you using your fruit in your own winery?
• Is your fruit going to an off-site winery? If so, do you have a contract, or have you built a relationship with the buyer?
• Are you shipping your fruit to a juice or wine processor?
• Market considerations are important, because many wine grape production regions have seen time and time again, gluts of certain varieties that stem from a perceived shortage. When processors and winery owners think they will be short, they may encourage planting of only one variety, leading to too many acres being planted, which eventually ca lead to too much fruit not having a home.

Grapevines

• Grapevines are propagated vegetatively or clonally, to retain the integrity of the flavors and characteristics of the final product. This means when you plant one clone of one variety, you have created a monoculture that is equally susceptible to any of several grapevine diseases throughout the seasons in your region.

Grafted Vines Versus Own-Rooted Vines

• Which should you plant?
• Own-rooted vines
  • Vine rooted in media - wholly one variety - e.g., Lemberger roots and Lemberger shoots and fruit
  • Pros: no graft union to act as an injury site (winter damage, crown gall)
  • Cons: no protection against phylloxera or extremely cold temperatures or root pests, including nematodes, which tend to less common in Northeastern United States vineyards.
• Grafted vines - A scion, such as Cabernet Sauvignon, is grafted to a rootstock, such as C3309.
  • Vines are grafted to enable vinifera grape production without infection from the root louse, phylloxera.
  • Rootstocks can affect vine vigor based on rootstock type, soil type, and site selection.
  • Some are winter hardy, which can reduce likelihood of winter damage
  • Pros: Protects susceptible scions from harmful insects, nematodes
  • Cons: Graft union may provide a site more susceptible to winter injury, crown gall; maintenance - requires hilling up and take-down in cool climates
• Finally, location, location, location
  • Something unique to the area, but is still climate-appropriate?
  • For example, while Malbec may be unique to your region, it may not withstand the extremely cold temperatures experienced there every few years.

Ordering Vines

• When should vines be ordered?
• To get one step closer to vines in the ground, vines should be ordered 1 to 2 years ahead of scheduled planting time. This is most certainly the case, if you plan to order vines on less common rootstocks. It is best to contact the nursery 2 years prior to planting to ask about availability and best time to order vines. See the National Grape Registry for nurseries across the United States.
