1-year Pre-plant · Determine Training System

The main objective in grape production:

Maximize sunlight interception.

Annual Cluster and Floral Development Chart

Figure 1. Concord Bud Development. Cluster initiation (arrows) in green shoots begins just after bloom, and by just before veraison, the buds reach stage 6 of 15. After the winter dormancy and bud break the following season, buds pick back up and finish developing via shoot emergence and growth by bloom, at which point the cycle begins anew.
*Dates on x-axis are approximate for each season. Adapted from Goffinet, Wine East 2001.

Regardless of the variety to be planted, a grower will need to be sure to install a trellis (the physical structure to which the vines are attached) within the first year of planting.  This will enable easier handling of the vines, as well as improve weed and pest management techniques and efficacy in the first two years of growth.  Deciding as early as possible will enable growers to calculate the amount of materials needed.  Figure 2 depicts a few training systems, with the most commonly used in NY being top wire cordon (juice grapes, hybrids, vines with procumbent growth habits) and mid-wire cordon, or VSP (Vitis vinifera varieties, some hybrids with upright growth habits).

Training Systems for Grape Vineyards

Variety selection can also dictate training system options.  For example, many of the varieties native to the US and their hybrids have procombent growth habits, meaning, then tend to grow toward the vineyard floor.  In these cases, a top wire cordon system can maximize sunlight interception, thus increasing fruitfulness in these varieties.  Conversely, Vitis vinifera varieties tend to have upright growth habits, lending themselves to a vertical shoot positioning (VSP) system. (Figure 3)  Either of these training systems can be expanded to manage excessive vigor, though dividing the canopies horizontally, as seen in Figure 4.

Train to a Variety

Figure 3.  Choose the appropriate training system for each variety planted.  'Cabernet Franc' is better suited to vertical shoot positioning (VSP) systems, while the hybrid 'Diamond' is best suited to top wire cordon training.

Horizontally Divide Canopies

Figure 4.  For overly vigorous sites, separating the canopy horizontally will improve sunlight interception.  A) Geneva Double Curtain (GDC) divides a top wire cordon system.  B)  A Lyre trellis divides a VSP system.

Why it is important to have a training system in place very soon after planting:

Training System Importance

Figure 5.  By allowing vines to crawl along the vineyard floor for an entire season, not only can weed control be more difficult, but training also gets very messy.

Vine training and trellis systems are explored in-depth in Wine Grape Production Guide for Eastern North America and Wine Grape Varieties in California.  Ideally, the goal is to establish and maintain a fairly uniform vineyard to allow for easier mechanical access and management.

Proper Training - Easier Management

Figure 6.  Proper training makes for easier pruning and canopy management.

NYWGF presents Introduction to New York Wine

Welcome to New York! Introduction to New York Wines
Building on the success of the newly updated New York Wine Reference Guide, NYWGF is pleased to bring comprehensive, expertly delivered New York wine education to your team each week from April 25th through June 20th, 2023. We welcome you to join wine writer and educator Dan Belmont as he leads this nine (9) part series - completely free for NYWGF Winery and Grower Members.
From our first 90-minute 'deep dive' into the wines of New York, to the subsequent 60- minute sessions on our major varietals and wine regions, this educational opportunity will be unlike any other and extremely valuable to winery and vineyard leaders, tasting room and marketing staff, as well as to trade, media, and consumers who are champions of New York wine. Tasting components are part of each session - with recommended wines for each session to be announced in advance of the seminar date.
IN THIS SESSION:
We agree with Eric Asimov who noted in the New York Times that "New York is the third largest wine- producing state in the country, after California and Washington. Yet it doesn't get nearly the respect it deserves." Fortunately, much has changed in the last few years and information about New York wines is being sought out by all levels of consumer, trade, and media. This session will empower you with knowledge and introduce you to the major regions, grapes, and styles of New York State wine, and provide an overview of statewide geography, geology, climate & history. Participants will gain conversational-level broad knowledge of New York State wine and leave excited about the upward trends in both quality winemaking and viticulture in New York State.
TASTING:
Arrowhead Spring Chardonnay 2021 (Niagara)
Boundary Breaks Dry Riesling 2021 (Finger Lakes)
Mazza Chautauqua Cellars Gew?rztraminer 2017 (Lake Erie)
Benmarl Winery Estate Cabernet Franc 2018 (Hudson Valley)
Macari Merlot 2019 (Long Island)
Vesco Ridge Diamond (Champlain Valley)
Meadowdale Winery Blue Jay Dechaunac (Upper Hudson)
Please Note: Suggested wines for tastings must be purchased separately and are not included with registration.
Tomorrow! Tue, April 25, 2023 9:00 AM - 10:00 AM EDT

Sessions are free for all NYWGF Members. Attendees must register for the full series and will be provided with seminar recordings if unable to attend live.
