Plassa
Plassa (also known as Scarlattino) is a red Italian wine grape variety that is grown in the Piedmont wine region of northwest Italy where it was once historically used as a table grape but now is almost always used for winemaking. Here the grape is most often used as a minor blending component adding tannins to wines made from Barbera, Neretta Cuneese, Grisa nera and Chatus.J. Robinson, J. Harding and J. Vouillamoz ''Wine Grapes - A complete guide to 1,368 vine varieties, including their origins and flavours'' pg 833 Allen Lane 2012 History The name ''Plassa'' is derived from the word ''pellaccia'' which in the local Piedmontese dialect means "hard skin" and is a reference to the very thick grape skins of Plassa berries. Ampelographers believe that the grape is native to Piedmont region where it has been historically associated with the communes of Bibiana, Bricherasio, Campiglione-Fenile, Pinerolo and San Secondo di Pinerolo in the province of Turin.

Grape Variety
This list of grape varieties includes cultivated grapes, whether used for wine, or eating as a table grape, fresh or dried (raisin, currant, sultana). For a complete list of all grape species including those unimportant to agriculture, see Vitis. The term ''grape variety'' refers to cultivars rather than actual botanical varieties according to the International Code of Nomenclature for Cultivated Plants, because they are propagated by cuttings and may have unstable reproductive properties. However, the term ''variety'' has become so entrenched in viticulture that any change to using the term ''cultivar'' instead is unlikely. Single species grapes While some of the grapes in this list are hybrids, they are hybridized within a single species. For those grapes hybridized across species, known as interspecific hybrids, see the section on multispecies hybrid grapes below.

Piedmont Wine
Piemonte wine is the range of Italian wines made in the region of Piedmont in the northwestern corner of Italy. The best-known wines from the region include Barolo and Barbaresco. They are made from the Nebbiolo grape. These wines are ideal for storage and a well-aged Barolo for instance may leave a feeling of drinking velvet because the tannins are polished and integrated more and more into the wine. As the wine matures the colour becomes more brownish and rust-red. Other popular grapes used for red wine production are Barbera and Dolcetto. Wine made with the Barbera grape is often fruity, with high acidity. It can be delicate with less tannin than wine made from the Nebbiolo grape. Dolcetto on the other side, is not, as the name indicates, sweet. Dolcetto means "little sweet one". (dolce is Italian for sweet). The grape gives fresh and dry red wines with some tannin. The wines made with the Dolcetto grape are typically consumed relatively young. The sparkling wine Asti s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grisa Nera
Grisa nera is a red Italian wine grape variety that is grown in the Piedmont wine region of northwest Italy where it is used in both winemaking and as a table grape. The grape is most often used as a minor blending component with wines made from Barbera, Neretta Cuneese and Plassa.J. Robinson, J. Harding and J. Vouillamoz ''Wine Grapes - A complete guide to 1,368 vine varieties, including their origins and flavours'' pg 441 Allen Lane 2012 History In the early 21st century, DNA profiling showed that Grisa nera had a parent-offspring relationship with another red Piedmontese wine grape, Avarengo, though it is not yet known which grape is the parent and which is the offspring. However, this strong relationship between two grapes that are grown almost exclusively in the Piedmont region strongly suggest that both varieties are native to Piedmont. Viticulture Grisa nera is a mid to late ripening variety that is used for both wine and table grape production. The vine can be very vi ...

Canopy Management
In viticulture, the canopy of a grapevine includes the parts of the vine visible aboveground - the trunk, cordon, stems, leaves, flowers, and fruit. The canopy plays a key role in light energy capture via photosynthesis, water use as regulated by transpiration, and microclimate of ripening grapes. Canopy management is an important aspect of viticulture due to its effect on grape yields, quality, vigor, and the prevention of grape diseases. Various viticulture problems, such as uneven grape ripening, sunburn, and frost damage, can be addressed by skillful canopy management.Weiss, S.B., D.C. Luth, and B. Guerra. 2003. Potential solar radiation in a VSP trellis at 38°N latitude. ''Practical Winery and Vineyard'' 25:16-27. In addition to pruning and leaf trim, the canopy is often trained on trellis systems to guide its growth and assist in access for ongoing management and harvest.J.

Plant Stem
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue. The stem can also be called halm or haulm. The stem is normally divided into nodes and internodes: * The nodes hold one or more leaves, as well as buds which can grow into branches (with leaves, conifer cones, or flowers). Adventitious roots may also be produced from the nodes. * The internodes distance one node from another. The term "shoots" is often confused with "stems"; "shoots" generally refers to new fresh plant growth including both stems and other structures like leaves or flowers. In most plants stems are located above the soil surface but some plants have underground stems. Stems have four main functions which are: * Support for and the elevation of leaves, flowers, and fruits. The stems ke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Growing Season (vine)
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 ...

Downy (mildew)
Downy mildew refers to any of several types of oomycete microbes that are obligate parasites of plants. Downy mildews exclusively belong to the Peronosporaceae family. In commercial agriculture, they are a particular problem for growers of crucifers, grapes and vegetables that grow on vines. The prime example is '' Peronospora farinosa'' featured in NCBI-Taxonomy and HYP3. This pathogen does not produce survival structures in the northern states of the United States, and overwinters as live mildew colonies in Gulf Coast states. It progresses northward with cucurbit production each spring. Yield loss associated with downy mildew is most likely related to soft rots that occur after plant canopies collapse and sunburn occurs on fruit. Cucurbit downy mildew only affects leaves of cucurbit plants. Symptoms Initial symptoms include large, angular or blocky, yellow areas visible on the upper surface. As lesions mature, they expand rapidly and turn brown. The under surface of infect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powdery Mildew
Powdery mildew is a fungal disease that affects a wide range of plants. Powdery mildew diseases are caused by many different species of ascomycete fungi in the order Erysiphales. Powdery mildew is one of the easier plant diseases to identify, as its symptoms are quite distinctive. Infected plants display white powdery spots on the leaves and stems. The lower leaves are the most affected, but the mildew can appear on any above-ground part of the plant. As the disease progresses, the spots get larger and denser as large numbers of asexual spores are formed, and the mildew may spread up and down the length of the plant. Powdery mildew grows well in environments with high humidity and moderate temperatures. Greenhouses provide an ideal moist, temperate environment for the spread of the disease. This causes harm to agricultural and horticultural practices where powdery mildew may thrive in a greenhouse setting. In an agricultural or horticultural setting, the pathogen can be controlle ...

Italian Wine
Italian wine is produced in every region of Italy. Italy is the world's largest producer of wine, with an area of under vineyard cultivation, and contributing a 2013–2017 annual average of 48.3 million hl of wine. In 2018 Italy accounted for 19 per cent of global production, ahead of France (17 per cent) and Spain (15 per cent). Italian wine is both exported around the world and popular domestically among Italians, who consume an average of 42 litres per capita, ranking fifth in world wine consumption. The origins of vine-growing and winemaking in Italy has been illuminated by recent research, stretching back even before the Phoenician, Etruscans and Greek settlers, who produced wine in Italy before the Romans planted their own vineyards. The Romans greatly increased Italy's viticultural area using efficient viticultural and winemaking methods. History Vines have been cultivated from the wild ''Vitis vinifera'' grape for millennia in Italy. It was previously believed that ...

Millerandage
Millerandage (or shot berries, hens and chicks and pumpkins and peas) is a potential viticultural hazard problem in which grape bunches contain berries that differ greatly in size and, most importantly, maturity. Its most common cause is cold, rainy or otherwise bad weather during the flowering stage of the vines though other factors, such as boron deficiency or fanleaf degeneration, may also play a role.J. Robinson (ed) ''"The Oxford Companion to Wine"'' Third Edition pgs 77, 291, 322, 443 Oxford University Press 2006 While millerandage will always cause a drop in yield, its potential impact on wine quality will vary, particularly by grape variety. For some varieties that are prone to uneven ripeness within a cluster, such as Sangiovese, Zinfandel and Gewürztraminer, the development of millerandage may be unfavorable due to "green flavors" from the potentially unripe grapes hidden within the cluster. For other varieties, such as Pinot noir or the Mendoza clone of Chardonnay, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ripe (wine)
In viticulture, ripeness is the completion of the ripening process of wine grapes on the vine which signals the beginning of harvest. What exactly constitutes ripeness will vary depending on what style of wine is being produced ( sparkling, still, fortified, ''rosé'', dessert wine, etc.) and what the winemaker and viticulturist personally believe constitutes ripeness. Once the grapes are harvested, the physical and chemical components of the grape which will influence a wine's quality are essentially set so determining the optimal moment of ripeness for harvest may be considered the most crucial decision in winemaking.J. Cox ''"From Vines to Wines"'' Fourth Edition, pg 97-106 Storey Publishing 1999 There are several factors that contribute to the ripeness of the grape. As the grapes go through ''veraison'', sugars in the grapes will continue to rise as acid levels fall. The balance between sugar (as well as the potential alcohol level) and acids is considered one of the most c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
