Progress 07/01/03 to 07/01/06
Outputs
This State project is being terminated because it is an exact duplicate of WNP00528.
Impacts
Wine grape production in our maritime climate appears to have a promising future, and judging from this year's harvest some very high quality wines will be produced. The climate has similarities to the classic wine growing areas of France and Germany. Many of the growers in western Washington are looking for a value added crop; this trial helps provide needed information on varieties, rootstocks and cultural methods for their success.

Progress 01/01/03 to 12/31/03
Outputs
Grants from the Washington Wine Advisory Board, American Vineyard Foundation, and Northwest Center for Small Fruit Research have helped support this project. The primary focus is to identify promising new varietals with emphasis on red cultivars. The trial has 3 elements which include a primary cultivar test plot consisting of 3 replications of 5 vines for a total of 15 vines per cultivar, enough to make at least 5 gallons of wine for evaluation. Part 2 is a pretest which consist of 3 vines per cultivar or selection; if they look promising, they are multiplied and added to the main cultivar trial. The third element is a rootstock trial, with Pinot Noir (clone 2A) grafted on 7 different rootstocks to evaluate their effect on maturity, pest resistance, productivity and wine quality. At the end of 2003, the rootstock trial was reduced to the 3 best performing rootstocks plus self rooted plants as control. Trial plots have been established at 2 locations: at WSU-Mt Vernon
and at a warmer site in Everson WA. This allows a comparison of the range of heat units in our maritime site. In 2002 the first wines were made and preliminary evaluation of the wines has taken place. In 2003 most of the trial was producing wines. Several wineries participated in the winemaking. Several varietals were made; in addition, Pinot 2A had wine varietals made from each of the rootstocks separately. Certain rootstocks enhanced ripening, brix and acids in Pinot Noir. Cultural studies were done on plastic screens for wind protection, cluster number, and in fruit hanging time; these studies were done to see the effect on fruit maturity.

Progress 01/01/02 to 12/31/02
Outputs
A grant from the Wine Advisory Board-WSDA supported the initiation of an extensive trial of new, promising wine grape varieties and selections, primarily for red wine, that may be well adapted to a cool maritime climate. The trial includes 3 elements: 1.)a wine grape variety trial, of 5 plants/plot x 3 reps, emphasizing early ripening, high quality red wine grapes; 2.) a rootstock trial of Pinot Noir clone 2A on 7 different rootstocks plus self rooted, to examine the potential effect of rootstocks on ripening and productivity and 3.)a varietal pretest of 3 plants/variety, with the best performing varieties to be added to the main test in future. The trial plots have been established at 2 locations: at the Mount Vernon station and at a cooperator's site in the Nooksack River valley near Everson. This will allow comparison of varieties at sites with lower and higher heat units. In 2000 grape plants were established in the vineyard plots, and the plots kept watered and
weeded as necessary. In early 2001installation of posts and wires was completed. Pruning and training of the vines was initiated. In August 2001 there was fruit for preliminary evaluation in both the rootstock and cultivar test blocks. In 2002 most of the trial plots had sufficient fruit for evaluation and some had enough fruit for production of varietal wine. A limited cultural test was conducted to study the effect of early and late plastic applications, ground mulch, and number of clusters per shoot (bunch thinning) on earlier fruit maturity. Samples were collected and tested for brix (soluble solids) and titratable acid to determine harvest maturity. Certain rootstocks were shown to have significant effect in advancing fruit maturity. The first crop for wine production was harvested in October 2002, and wine from that crop is in fermentation. Sampling of wine for evaluation will begin in summer 2003.
Impacts
The potential for wine grape production in the Puget Sound area is very good, given a careful choice of site and the selection of well adapted varieties to produce high quality wine. The climate here is similar to some of the classic wine producing areas of France and Germany. For growers in this area seeking a potential high return crop, this trial will provide much needed information on choice of variety and rootstock for establishing a successful vineyard.

the vineyard plots, and provided with stakes and plastic protectors. During the summer, irrigation systems were installed, and the plots kept watered and weeded as necessary. In early 2001 installation of posts and wires was completed. Pruning and training of the vines to a Guyot system was initiated. In August 2001 there was fruit for preliminary evaluation in both the rootstock and cultivar test blocks. Samples were collected and tested for brix (soluble solids) and titratable acid to determine harvest maturity. The first crop for wine production will be harvested in 2002.

The trial plots have been established at 2 locations: at the Mount Vernon station and at a cooperator's vineyard site in the upper Skagit River valley near Concrete. This will allow comparison of varieties at sites with lower and higher heat units. In April 2000 ground preparation was completed at both sites and grape plants
established in the vineyard plots, and provided with stakes and plastic protectors. During the summer, irrigation systems were installed, and the plots kept watered and weeded as necessary. In fall 2000 installation of posts and wires was begun and will be completed by early 2001. Pruning and training will be initiated over the winter. Some of the plants produced specimen fruit in the fall of 2000, and by the fall of 2001 there will be some fruit for preliminary evaluation on most cultivars. The first crop for wine production will be harvested in 2002.
