Yakima Valley (AVA)
Yakima Valley is the first American Viticultural Area (AVA) established in Washington state on April 3, 1983 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by the Yakima Valley Appellation Committee to propose a viticultural area named "Yakima Valley." The area petitioned is a valley centered around the Yakima River in south central Washington. The Yakima Yalley geographically is nearly long and wide at its widest point and encompassed approximately . Currently within the vast Columbia Valley AVA, the Yakima Valley appellation cultivates more than giving the region the largest concentration of wineries and vineyards in the state. The most widely planted varietals in the area are Chardonnay, Riesling, Merlot, Cabernet Sauvignon, Pinot gris, and Syrah. Nearly 40% of Washington's annual wine production is made from Yakima Valley grapes. In addition to grapes, the Yakima Valley is also home to several fruit orchards growing ap ...

American Viticultural Area
An American Viticultural Area (AVA) is a designated wine grape-growing region in the United States, providing an official appellation for the mutual benefit of winery, wineries and consumers. Winemakers frequently want their consumers to know about the geographic pedigree of their wines, as wines from a particular area can possess distinctive characteristics. Consumers often seek out wines from specific AVAs, and certain wines of particular pedigrees can claim premium prices and loyal customers. If a wine is labeled with an AVA, at least 85% of the grapes that make up the wine must have been grown in the AVA, and the wine must be fully finished within the U.S. state, state where the AVA is located. Regulations Since 1980, the boundaries of AVAs were defined by the Bureau of Alcohol, Tobacco and Firearms , Bureau of Alcohol, Tobacco and Firearms (ATF), an independent bureau within the United States Department of the Treasury that received and handled petitions for viticultural ar ...

White Bluffs AVA
White Bluffs is an American Viticultural Area (AVA) located about north of Tri-Cities on the plateaus overlooking the Columbia River. The area lies entirely within the established vast Columbia Valley appellation. White Bluffs AVA was recognized by the Alcohol and Tobacco Tax and Trade Bureau {TTB), Treasury on July 19, 2021, after reviewing the petition submitted by Whitman College professor and geologist, Dr. Kevin Pogue, on behalf of local winemakers and vineyard owners, proposing to establish the viticultural area named "White Bluffs." Within its , the area has nine commercial vineyards cultivating approximately and a single winery. The distinguishing features of White Bluffs are its topography, geology, soils, and climate. History White Bluff gets its name from the whiteish sedimentary layers that appear on the cliffs above the Columbia River. Named the Ringold formation, the layer is ancient lakebed sediment covered with windblown silt and Missoula Flood deposits. Ac ...

Black Muscat
Black Muscat (or Muscat Hamburg) is a red ''Vitis vinifera'' grape variety derived from the crossing of the Schiava Grossa and Muscat of Alexandria by Seward Snow, Head Gardener to Earl de Grey at Wrest Park, Bedfordshire UK in 1850, according to the Vitis International Variety Catalogue. It is known under a variety of local names such as '' Golden Hamburg, and Black Hamburg'' in the US; ''Muscat de Hambourg (or Hamburgh)'' in France; ''Moscato di Amburgo'' in Italy; and ''Muscat Gamburgskiy'' in Russia and former Soviet Union countries. Confusingly, Black Hamburg is also used as a synonym for its maternal parent. It is commonly produced as table wine but in California's Central Valley it has been used in the production of dessert wine. As a dessert wine it can be highly aromatic with a rich coloring. In the United States, Black Muscat is grown in wine appellations in California, Virginia, Oregon, Texas, and Washington. In Canada, it is also found on Vancouver Island. In Fr ...

Barbera
Barbera is a red Italian wine grape variety that, as of 2000, was the third most-planted red grape variety in Italy (after Sangiovese and Montepulciano). It produces good yields and is known for deep color, full body, low tannins and high levels of acidity.J. Robinson (ed) ''The Oxford Companion to Wine'' Third Edition pg 62-63 Oxford University Press 2006 Century-old vines still exist in many regional vineyards and allow for the production of long-aging, robust red wines with intense fruit and enhanced tannic content. The best-known appellation is the DOCG (Denominazione di Origine Controllata e Garantita) Barbera d'Asti in the Piedmont region: the highest-quality Nizza DOCG wines are produced within a sub-zone of the Barbera d'Asti production area. When young, the wines offer a very intense aroma of fresh red cherries and blackberries. In the lightest versions notes of cherries, raspberries and blueberries and with notes of blackberry and black cherries in wines made of mo ...

Bedrock
In geology, bedrock is solid rock that lies under loose material ( regolith) within the crust of Earth or another terrestrial planet. Definition Bedrock is the solid rock that underlies looser surface material. An exposed portion of bedrock is often called an outcrop. The various kinds of broken and weathered rock material, such as soil and subsoil, that may overlie the bedrock are known as regolith. Engineering geology The surface of the bedrock beneath the soil cover (regolith) is also known as ''rockhead'' in engineering geology, and its identification by digging, drilling or geophysical methods is an important task in most civil engineering projects. Superficial deposits can be very thick, such that the bedrock lies hundreds of meters below the surface. Weathering of bedrock Exposed bedrock experiences weathering, which may be physical or chemical, and which alters the structure of the rock to leave it susceptible to erosion. Bedrock may also experience subsur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Loam
Loam (in geology and soil science) is soil composed mostly of sand (particle size > ), silt (particle size > ), and a smaller amount of clay (particle size < ). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. In the USDA, United States Department of Agriculture, soil texture, textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and humus than sandy soils, have better drainage and infiltration of water and air than silt- and clay-rich soils, and are easier to tillage, till than clay soils. In fact, the primary definition of loam in most dictionaries is soils containing hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silt
Silt is granular material of a size between sand and clay and composed mostly of broken grains of quartz. Silt may occur as a soil (often mixed with sand or clay) or as sediment mixed in suspension (chemistry), suspension with water. Silt usually has a floury feel when dry, and lacks Plasticity (physics), plasticity when wet. Silt can also be felt by the tongue as granular when placed on the front teeth (even when mixed with clay particles). Silt is a common material, making up 45% of average modern mud. It is found in many river deltas and as wind-deposited accumulations, particularly in central Asia, north China, and North America. It is produced in both very hot climates (through such processes as collisions of quartz grains in dust storms) and very cold climates (through such processes as glacial grinding of quartz grains.) Loess is soil rich in silt which makes up some of the most fertile agricultural land on Earth. However, silt is very vulnerable to erosion, and it has poo ...

Growing Degree-day
Growing degree days (GDD), also called growing degree units (GDUs), are a heuristic tool in phenology. GDD are a measure of heat accumulation used by horticulturists, gardeners, and farmers to predict plant and animal development rates such as the date that a flower will bloom, an insect will emerge from dormancy, or a crop will reach maturity. GDD is credited to be first defined by Reaumur in 1735. Introduction In the absence of extreme conditions such as unseasonal drought or disease, plants grow in a cumulative stepwise manner which is strongly influenced by the ambient temperature. Growing degree days take aspects of local weather into account and allow gardeners to predict (or, in greenhouses, even to control) the plants' pace toward maturity. Unless stressed by other environmental factors like moisture, the development rate from emergence to maturity for many plants depends upon the daily air temperature. Because many developmental events of plants and insects depend on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goose Gap AVA
Goose Gap is the 19th American Viticultural Area (AVA) in Washington, United States. It encompasses the local region surrounding Goose Mountain in Benton County between Kiona to the west, and Richland along the Columbia River to the east.
