The Winery Name
We are often asked, "What is a Convergence Zone" or "How did you come up with your name"? The naming of the winery is really distilled into three unique parts:
- It's a weather phenomenon in the Puget Sound area. It just so happens that our winery started in the middle of the CZ.
- "Zone" is also a city planning term (ex. residential zone, commercial zone, industrial zone, etc). The founder and winemaker of Convergence Zone, Scott Greenberg, is a retired city planner. We though it was only fitting to create a "Convergence Zone" bringing together city planning and the art of winemaking.
- It means a convergence of different grapes, vineyards and winemaking styles to product drinkable, agreeable, aromatic, palate-pleasing, and long-finishing wines.
Red Mountain (Ciel du Cheval, Hedges, Kiona, Heart of the Hill, E&E Shaw, Scooteney Flats):
The Red Mountain AVA is an American Viticultural Area that includes the land surrounding Red Mountain in Benton County, Washington. It is part of the Yakima Valley AVA, which in turn is part of the larger Columbia Valley AVA. Located between Benton City and the City of West Richland, the Red Mountain AVA is the smallest in the state at only 4,040 acres (1,630 ha) in area. The area has 600 acres under cultivation of primarily red varietals including Cabernet Sauvignon, Merlot, Sangiovese, Cabernet Franc and Syrah. The reputation of the wines produced in this area has brought Red Mountain AVA worldwide acclaim. The vineyards in this appellation have produced grapes for some of the most sought after wines in Washington State.
Snipes Mountain (Upland):
Snipes Mountain AVA is an American Viticultural Area located in the Yakima Valley of Washington State. It was approved by the Bureau of Alcohol, Tobacco, Firearms and Explosives on January 21, 2009 making it Washington's 10th federally designated AVA. It is the second smallest AVA in the state, after the Red Mountain AVA, and has one of the state's longest viticultural histories. The 4,145 acres appellation is a sub-AVA of the Yakima Valley AVA and the Columbia Valley AVA. It is located above and between the towns of Sunnyside and Granger around Outlook, Washington, in the southeast corner of the Yakima Valley.
Columbia Valley (Bacchus, Dineen, Gamache, Tudor Hills):
The Columbia Valley AVA (referred to locally as the Columbia Basin) is an American Viticultural Area which lies in the Columbia River Plateau, through much of central and southern Washington State, with a small section crossing into the neighboring state of Oregon. The AVA includes the drainage basin of the Columbia River and its tributaries through much of Washington. Allen Shoup, president of Washington State's largest winery Chateau Ste. Michelle, understood the importance of obtaining appellation status for Washington State to grow the reputation of the vineyards. He hired Drs. Wade Wolfe and Walter Clore to petition the federal government for appellation status, a request that was granted in 1984. The Columbia Valley AVA is the largest wine region in the state of Washington, including over 11,000,000 acres of which over 40,000 acres are planted in vineyards. The Columbia Valley AVA includes 99% of the total vineyard area planted in the state of Washington. Grapes grown here include Cabernet Sauvignon, Merlot, Chardonnay, Riesling, Syrah, Pinot gris, and Sauvignon blanc. Concord grapes and other Vitis labrusca grapes are grown in the region as well. The unique climates of the area allow the Columbia Valley to produce wines that are very fruit-forward, like California wine, but which also retain some of the balance and structure of European wine.
Horse Heaven Hills (Phinny Hill):
Horse Heaven Hills is located in south-central Washington along the Washington-Oregon border. The area takes its name from an early pioneer who said, upon seeing the region and its wide prairies and expanses, ‘‘Surely this is Horse Heaven!”
Two-thirds of the acreage is planted to red wine grapes and one-third to white wine grapes. For reds, Cabernet Sauvignon and Merlot dominate. Whites are almost evenly split between Chardonnay and Riesling.
The area is among Washington’s warmer growing regions, allowing a wide variety of grapes to ripen successfully. Many vineyards in the Horse Heaven Hills are planted on south-facing slopes, providing for extended sun exposure.
The Horse Heaven Hills is 570,000 acres (230,671 ha) in size, with elevations ranging from 200 feet (61 m) above sea level along the Columbia River to 1,800 feet (549 m) at the northern boundary.
Wahluke Slope (Weinbau):
Wahluke Slope, named after a Native American word for “watering place,” lies in south-central Washington. The area is geographically isolated, bordered by the Columbia River, Saddle Mountains, and Hanford Reach National Monument.
As one of the warmest regions in the state, the Wahluke Slope is known primarily for red grape varieties, particularly Cabernet Sauvignon, Merlot, and Syrah. Wahluke Slope wines tend to be ripe and full-bodied with pure varietal fruit flavors.
The major distinguishing feature of the Wahluke Slope is its uniformity in aspect, soil type, and climate. The entire appellation lies on a broad, south-facing slope with a constant, gentle grade of less than 8%. This, along with the proximity to the Columbia River, helps minimize the risk of frost, which can affect other areas of the state.
The entire 81,000-acre appellation sits on a large alluvial fan, making the soils notably uniform over a large area. The topsoil is deep, wind-blown sand with a depth, on average, of more than 5 feet (150cm). This provides both ample drainage for vinifera vines and greater uniformity in plant vigor and ripening than seen in other areas of Washington.
Elevations vary between 425 feet by the Columbia River to 1,480 feet above sea level, though most vineyards lie below 1,000 feet. Precipitation averages less than 6 inches (15cm) annually. Irrigation is therefore required to grow vinifera grapes. Winds in the area lead to smaller leaf size and smaller grape clusters compared to other regions, concentrating the resulting wines.
