TerroirTerroir (tɛˈrwɑːr, tɛʁwaʁ; from terre, "land") is a French term used to describe the environmental factors that affect a crop's phenotype, including unique environment contexts, farming practices and a crop's specific growth habitat. Collectively, these contextual characteristics are said to have a character; terroir also refers to this character. Some artisanal crops for which terroir is studied include wine, cider, coffee, tobacco, olive oil, chocolate, chili peppers, hops, agave (for making tequila and mezcal), tomatoes, heritage wheat, maple syrup, tea, and cannabis.
Aroma of wineThe aromas of wine are more diverse than its flavours. The human tongue is limited to the primary tastes perceived by taste receptors on the tongue – sourness, bitterness, saltiness, sweetness and savouriness. The wide array of fruit, earthy, leathery, floral, herbal, mineral, and woodsy flavour present in wine are derived from aroma notes sensed by the olfactory bulb. In wine tasting, wine is sometimes smelled before taking a sip in order to identify some components of the wine that may be present.
New Zealand wineNew 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.
Chilean wineChile has a long history in the production of wine, with roots dating back to the 16th century when the Spanish conquistadors introduced Vitis vinifera vines to the region. In the mid-19th century, French wine varieties such as Cabernet Sauvignon, Merlot, Carmenère, and Franc were introduced. During the early 1980s, the Chilean wine industry underwent a renaissance with the introduction of stainless steel fermentation tanks and the use of oak barrels for aging. This led to a rapid growth in exports as quality wine production increased.
Malolactic fermentationMalolactic conversion (also known as malolactic fermentation or MLF) is a process in winemaking in which tart-tasting malic acid, naturally present in grape must, is converted to softer-tasting lactic acid. Malolactic fermentation is most often performed as a secondary fermentation shortly after the end of the primary fermentation, but can sometimes run concurrently with it. The process is standard for most red wine production and common for some white grape varieties such as Chardonnay, where it can impart a "buttery" flavor from diacetyl, a byproduct of the reaction.
Climate categories in viticultureIn viticulture, the climates of wine regions are categorised based on the overall characteristics of the area's climate during the growing season. While variations in macroclimate are acknowledged, the climates of most wine regions are categorised (somewhat loosely based on the Köppen climate classification) as being part of a Mediterranean (for example Tuscany), maritime (ex: Bordeaux) or continental climate (ex: Columbia Valley).
Propagation of grapevinesThe propagation of grapevines is an important consideration in commercial viticulture and winemaking. Grapevines, most of which belong to the Vitis vinifera family, produce one crop of fruit each growing season with a limited life span for individual vines. While some centenarian old vine examples of grape varieties exist, most grapevines are between the ages of 10 and 30 years. As vineyard owners seek to replant their vines, a number of techniques are available which may include planting a new cutting that has been selected by either clonal or mass (massal) selection.
ViticultureViticulture (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 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.
Loire ValleyThe Loire Valley (Val de Loire, val də lwaʁ; Traoñ al Liger), spanning , is a valley located in the middle stretch of the Loire river in central France, in both the administrative regions Pays de la Loire and Centre-Val de Loire. The area of the Loire Valley comprises about . It is referred to as the Cradle of the French and the Garden of France due to the abundance of vineyards, fruit orchards (such as cherries), and artichoke, and asparagus fields, which line the banks of the river.
