TrollingerTrollinger, Schiava, or Vernatsch, is a red German/Italian wine grape variety that was likely first originally cultivated in the wine regions of South Tyrol and Trentino, but today is almost exclusively cultivated on steep, sunny locations in the Württemberg wine region of Baden-Württemberg. It is primarily known under the synonyms Trollinger in Germany, Vernatsch in South Tyrol and Schiava in other Italian regions.
PhylloxeraGrape phylloxera is an insect pest of commercial grapevines worldwide, originally native to eastern North America. Grape phylloxera (Daktulosphaira vitifoliae (Fitch 1855) belong to the family Phylloxeridae, within the order Hemiptera, bugs); originally described in France as Phylloxera vastatrix; equated to the previously described Daktulosphaera vitifoliae, Phylloxera vitifoliae. The insect is commonly just called phylloxera (fɪˈlɒksərə; from φύλλον, leaf, and ξηρός, dry).
Wachau wineWachau is one of Austria's most established and notable wine regions, specializing in dry wines made from Riesling and Grüner Veltliner. Located in Lower Austria along the Danube, west of Vienna and Krems an der Donau, it is one of the westernmost wine producing regions in Austria with only a few scattered plantings in Tyrol being further west. While most of Austria follows a wine classification systems based on ripeness and harvest must weight that parallels the German wine classification system, Wachau wines have a unique classification system.
Rheinhessen (wine region)Rheinhessen (in English often Rhine-Hesse or Rhenish Hesse) is the largest of 13 German wine regions (Weinanbaugebiete) for quality wines (QbA and Prädikatswein) with under cultivation in 2018. Named for the traditional region of Rhenish Hesse, it lies on the left bank of the Rhine between Worms and Bingen in the federal state of Rhineland-Palatinate. Despite its historic name it is currently no longer part of the federal-state of Hesse, this being the case since the end of World War II.
Bacchus (grape)Bacchus is a white wine grape created by viticulturalist Peter Morio at the Geilweilerhof Institute for Grape Breeding in the Palatinate in 1933. He crossed a Silvaner x Riesling cross with Müller-Thurgau. Bacchus received varietal protection and was released for general cultivation in 1972. Its name is taken from Roman name of the Greek wine god Dionysus. Bacchus can reach high must weights, and has no high requirement for sites it can be planted and can grow where Riesling, for example, does not ripen reliably.
SpätleseSpätlese (literal meaning: "late harvest"; plural form is Spätlesen) is a German wine term for a wine from fully ripe grapes, the lightest of the late harvest wines. Spätlese is a riper category than Kabinett in the Prädikatswein category of the German wine classification and is the lowest level of Prädikatswein in Austria, where Kabinett is classified in another way. In both cases, Spätlese is below Auslese in terms of ripeness. The grapes are picked at least seven days after normal harvest, so they are riper and have a higher sugar content.
Russian wineRussian wine refers to wine made in Russia, at times also including the disputed region of Crimea. The vast majority of Russia's territory is unsuitable for grape growing, with most of the production concentrated in parts of Krasnodar and Rostov regions, as well as Crimea. The Russian market is characterized by the presence of many low-cost products, with a significant part of local wines having a retail price of less than 100 rubles ($).
Yeast assimilable nitrogenYeast assimilable nitrogen or YAN is the combination of free amino nitrogen (FAN), ammonia (NH3) and ammonium (NH4+) that is available for a yeast, e.g. the wine yeast Saccharomyces cerevisiae, to use during fermentation. Outside of the fermentable sugars glucose and fructose, nitrogen is the most important nutrient needed to carry out a successful fermentation that doesn't end prior to the intended point of dryness or sees the development of off-odors and related wine faults.
Virginia wineVirginia wine refers to wine made primarily from grapes grown in the commonwealth of Virginia. Wine has been produced in the area since the early days of European colonization in the 17th century. Virginia has hot humid summers that can be challenging to viticulture, and only within the last twenty years has the industry developed beyond novelty status. By tonnage, Vitis vinifera varieties represents 75% of total production. French hybrids varieties account for nearly 20% of total wine grape production in the commonwealth, while American varietals make up only about 5% of the total.
