Winkler Index
The Winkler Index, sometimes known as the Winkler Scale or Winkler Regions, is a technique for classifying the climate of wine growing regions based on heat summation or growing degree-days. In the system, geographical areas are divided into five climate regions based on temperature converted to growing degree-days, and is commonly known as Regions I–V (see below). The system was developed at the University of California, Davis by A. J. Winkler and Maynard Amerine. The system The system is based on both the hypothesis and observations that grapevines do not grow if the temperature is below 50 °F (10 °C). Each day during the growing season (assumed under the system to be April 1 through October 31 in the Northern Hemisphere; October 1 through April 30 in the Southern Hemisphere) are assigned growing degree-days according to the amount that the day's average temperature exceeds this threshold; one degree day per degree Fahrenheit over 50 °F (or with SI units, de ...

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 ...

Oregon Wine
The state of Oregon in the United States has established an international reputation for its production of wine, ranking fourth in the country behind California, Washington, and New York. Oregon has several different growing regions within the state's borders that are well-suited to the cultivation of grapes; additional regions straddle the border between Oregon and the states of Washington and Idaho. Wine making dates back to pioneer times in the 1840s, with commercial production beginning in the 1960s. American Viticultural Areas entirely within the state are the Willamette Valley AVA (with 10 nested AVAs) and the Southern Oregon AVA with (5 nested AVAs). Parts of the Columbia Gorge, Walla Walla Valley, and Snake River Valley AVAs lie within Oregon. Pinot noir and Pinot Gris are the top two grapes grown, with over harvested in 2016. Oregon winemakers sold just under 3.4 million cases in 2016. With 908 wineries in Oregon, a tourism industry has developed around wine tasting. M ...

The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile. In 1818, after declaring in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nova Scotia Wine
Nova Scotia wine is Canadian wine produced in the Canadian province of Nova Scotia. Nova Scotia's wineries are primarily organized under the Wine Association of Nova Scotia, though not all wineries are members. The industry began in the late 1970s with the original Grand Pré Winery in the Annapolis Valley of Nova Scotia. Location The Nova Scotia wine region can be divided into 4 main regions: Annapolis Valley, Gaspereau Valley, South Shore, and the Malagash Peninsula. Besides these main regions, grapes intended for wine production are being produced by independent growers across the province, including Cape Breton Island. History Grape growing in Nova Scotia has been documented as early as the 1600s, where writing has noted that vines were planted in Annapolis Royal. In 1634 the governor of Acadia, Isaac de Razilly, wrote, “Bordeaux vines have been planted that are doing very well,” making the first mention of wine grape cultivation anywhere in Canada Razilly's vineyar ...

Southern England
Southern England, or the South of England, also known as the South, is an area of England consisting of its southernmost part, with cultural, economic and political differences from the Midlands and the North. Officially, the area includes Greater London, the South East, the West Country (or the South West), and the East (sometimes referred to as East Anglia). The distinction between the south and rest of England and Great Britain is sometimes referred to as the north–south divide. With a population of nearly 28 million; and an area of , the south accounts for roughly 40% of the population of the United Kingdom and approximately 25% of its area. Definitions For official purposes, the UK government does not refer to the Southern England as a single entity, but the Office for National Statistics divides UK into twelve regions.

Central Otago Wine Region
The Central Otago wine region is a geographical indication in New Zealand's South Island, and the world's southernmost commercial wine growing region. Central Otago is best known for Pinot Noir, but many white wine varieties are also popular. History of the wine region Significant European occupation in this region started with the Otago Gold Rush in the 1860s. A French immigrant gold miner, Jean Desire Feraud, soon started planting vines and embarking upon small-scale commercial wine production, even winning medals in Australian wine competitions. Late in the nineteenth century, the New Zealand government hired Romeo Bragato to survey the country. While this early experimentation showed the wine-growing potential of the region, the wine industry did not survive for long on a commercial basis. Starting in the 1950s, and up through the end of the 1970s, small-scale trial plantings of vines began again both by private individuals and under the auspices of the New Zealand Depart ...

Annual Growth Cycle Of Grapevines
The annual growth cycle of grapevines is the process that takes place in the vineyard each year, beginning with bud break in the spring and culminating in leaf fall in autumn followed by winter dormancy. From a winemaking perspective, each step in the process plays a vital role in the development of grapes with ideal characteristics for making wine. Viticulturalists and vineyard managers monitor the effect of climate, vine disease and pests in facilitating or impeding the vine's progression from bud break, flowering, fruit set, veraison, harvesting, leaf fall and dormancy-reacting if need be with the use of viticultural practices like canopy management, irrigation, vine training and the use of agrochemicals. The stages of the annual growth cycle usually become observable within the first year of a vine's life. The amount of time spent at each stage of the growth cycle depends on a number of factors-most notably the type of climate (warm or cool) and the characteristics of the grap ...

Huglin Index
Pierre Huglin developed a bioclimatic heat index for vineyards, the Huglin heat sum index (or ''after Huglin'' respectively -warmth index or short Huglin index,) in which the temperature sum over the temperature threshold of 10 °C is calculated and then summed for all days from beginning of April to end of September. The calculation uses both the daily average temperatures and the maximum temperatures and slightly modifies the calculated total according to latitude. Each grape variety needs a certain amount of heat in order to be cultivated successfully in the long term in a given area. The calculated heat sums, which are based on data from weather stations or from climate models, differ in that they are too low compared to the actual values in the vineyards. The index does not take into account e.g. thermally favoured hillsides where temperature values may be higher by about 1.5 °C to 2 °C. Definition & Calculation The Huglin index is calculated as a product o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South African Wine
South African wine has a history dating back to 1659 with the first bottle being produced in Cape Town by its founder and gouverner Jan van Riebeeck. Access to international markets led to new investment in the South African wine market. Production is concentrated around Cape Town, with major vineyard and production centres at Constantia, Paarl, Stellenbosch and Worcester. There are about 60 appellations within the Wine of Origin (WO) system, which was implemented in 1973 with a hierarchy of designated production regions, districts and wards. WO wines must only contain grapes from the specific area of origin. "Single vineyard" wines must come from a defined area of less than 6 hectares. An "Estate Wine" can come from adjacent farms if they are farmed together and wine is produced on site. A ward is an area with a distinctive soil type or climate and is roughly equivalent to a European appellation. History The roots of the South African wine industry can be traced to the expl ...

New Zealand Wine
New Zealand wine is produced in several of its distinct winegrowing regions. As an island country in the South Pacific Ocean, New Zealand has a largely maritime climate, although its elongated geography produces considerable regional variation from north to south. Like many other New World wines, New Zealand wine is usually produced and labelled as single varietal wines, or if blended, winemakers list the varietal components on the label. New Zealand is best known for its Marlborough Sauvignon Blanc, and more recently its dense, concentrated Pinot Noir from Marlborough, Martinborough and Central Otago. While New Zealand wine traces its history to the early 19th century, the modern wine industry in New Zealand began in the mid-20th century and expanded rapidly in the early 21st century, growing by 17% a year from 2000 to 2020. In 2020, New Zealand produced from of vineyard area, of which ha (about two-thirds) is dedicated to Sauvignon Blanc. Nearly 90% of total production is ...
