Van Duzer Corridor AVA
The Van Duzer Corridor AVA, a sub-appellation of the Willamette Valley AVA located within Polk County, Oregon, in the United States, is an American Viticultural Area approved by the Alcohol and Tobacco Tax and Trade Bureau on December 13, 2018 and effective January 14, 2019. The Van Duzer Corridor AVA lies entirely within the established Willamette Valley AVA and covers approximately . When the petition was submitted there were 17 (now 18) commercially-producing vineyards covering a total of approximately , as well as six wineries (now 9), within the AVA. The distinguishing features of the Van Duzer Corridor AVA are its topography, climate, and soils. Topography Topography is characterized by low elevations and gently rolling hills. The low elevations allow cool breezes to flow relatively unimpeded from the Pacific Ocean, through the Oregon Coast Range, forming a wind corridor gap known as the Van Duzer corridor. The western end of the Van Duzer Corridor wind gap is narrow a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 The boundaries of AVAs are defined by the Tax and Trade Bureau (TTB), a component of the United States Department of the Treasury. The TTB defines AVAs at the request of wineries and other petitioners. Prior to the TTB's creation in 2003, the Treasury’s Bureau of Alcohol ...

Riesling
Riesling (, ; ) is a white grape variety that originated in the Rhine region. Riesling is an aromatic grape variety displaying flowery, almost perfumed, aromas as well as high acidity. It is used to make dry, semi-sweet, sweet, and sparkling white wines. Riesling wines are usually varietally pure and are seldom oaked. , Riesling was estimated to be the world's 20th most grown variety at (with an increasing trend),J. Robinson (ed) ''The Oxford Companion to Wine'' Third Edition, Oxford University Press 2006, p. 746: ''"Vine varieties"'', . but in terms of importance for quality wines, it is usually included in the "top three" white wine varieties together with Chardonnay and Sauvignon blanc. Riesling is a variety that is highly "''terroir''-expressive", meaning that the character of Riesling wines is greatly influenced by the wine's place of origin. In cool climates (such as many German wine regions), Riesling wines tend to exhibit apple and tree fruit notes with noticeable leve ...

Phenolic Compounds (wine)
The phenolic content in wine refers to the phenolic compounds—natural phenol and polyphenols—in wine, which include a large group of several hundred chemical compounds that affect the taste, color and mouthfeel of wine. These compounds include phenolic acids, stilbenoids, flavonols, dihydroflavonols, anthocyanins, flavanol monomers (catechins) and flavanol polymers (proanthocyanidins). This large group of natural phenols can be broadly separated into two categories, flavonoids and non-flavonoids. Flavonoids include the anthocyanins and tannins which contribute to the color and mouthfeel of the wine. The non-flavonoids include the stilbenoids such as resveratrol and phenolic acids such as benzoic, caffeic and cinnamic acids. Origin of the phenolic compounds The natural phenols are not evenly distributed within the fruit. Phenolic acids are largely present in the pulp, anthocyanins and stilbenoids in the skin, and other phenols (catechins, proanthocyanidins and flavonols) i ...

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. 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 accumulation of specific quantities of heat, it is possib ...

Viticulture
Viticulture (from the Latin word for ''vine'') or winegrowing (wine growing) is the cultivation and harvesting of grapes. It is a branch of the science of horticulture. While the native territory of ''Vitis vinifera'', the common grape vine, ranges from Western Europe to the Iran, Persian shores of the Caspian Sea, the vine has demonstrated high levels of adaptability to new environments, hence viticulture can be found on every continent except Antarctica. Duties of the viticulturist include monitoring and controlling Pest (organism), pests and Plant pathology, diseases, fertilizer, fertilizing, irrigation (wine), irrigation, canopy (grape), canopy Glossary of viticultural terms#Canopy management, management, monitoring fruit development and Typicity, characteristics, deciding when to harvest (wine), harvest, and vine pruning during the winter months. Viticulturists are often intimately involved with winemakers, because vineyard management and the resulting grape characteristics ...

Van Duzer Corridor
H. B. Van Duzer Forest State Scenic Corridor is a scenic driving route along Route 18 in Lincoln, Tillamook, and Polk counties in the U.S. state of Oregon that passes through a forested corridor. The Van Duzer Corridor stretches from northwestern Polk County to Lincoln City, passing through the Northern Oregon Coast Range. The forest corridor was named for Henry B. Van Duzer, a member of the Oregon State Highway Commission and president of the Inman Poulson Logging Company, who was appointed by Governor I. L. Patterson as the first chairman of the Oregon State Parks Commission in 1929. The land, purchased by the State of Oregon between 1935 and 1942, is managed by the Oregon Parks and Recreation Department, which also maintains a scenic rest stop on the route. An old growth Douglas-fir forest is located along the Salmon River. Roosevelt elk can be seen along the route.

Oregon Coast Range
The Oregon Coast Range, often called simply the Coast Range and sometimes the Pacific Coast Range, is a mountain range, in the Pacific Coast Ranges physiographic region, in the U.S. state of Oregon along the Pacific Ocean. This north-south running range extends over from the Columbia River in the north on the border of Oregon and Washington, south to the middle fork of the Coquille River. It is wide and averages around in elevation above sea level. The coast range has three main sections, a Northern, Central, and Southern. The oldest portions of the range are over 60 million years old, with volcanics and a forearc basin as the primary mountain building processes responsible for the range. It is part of the larger grouping known as the Pacific Coast Ranges that extends over much of the western edge of North America from California to Alaska. The range creates a rain shadow effect for the Willamette Valley that lies to the east of the mountains, creating a more stable climate a ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Soil
Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Some scientific definitions distinguish ''dirt'' from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three-state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists regard soil as an ecosystem. Most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate
Climate is the long-term weather pattern in an area, typically averaged over 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, including the atmosphere, hydrosphere, cryosphere, lithosphere and biosphere and the interactions between them. The climate of a location is affected by its latitude/longitude, terrain, altitude, land use and nearby water bodies and their currents. Climates can be classified according to the average and typical variables, most commonly temperature and precipitation. The most widely used classification scheme was the Köppen climate classification. The Thornthwaite system, in use since 1948, incorporates evapotranspiration along with temperature ...

Topography
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the land forms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial, and cultural features such as roads, land boundaries, and buildings. In the United States, topography often means specifically ''relief'', even though the USGS topographic maps record not just elevation contours, but also roads, populated places, structures, land boundaries, and so on. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms; this is also known as geomorphometry. In modern usage, this involves generation of elevation data in digital form (DEM). It is often considered to include the graphic representation of t ...
