Dionysus ( ; Greek: Διόνυσος "Dionysos") is the god of the grape harvest, winemaking and wine, of ritual madness, fertility, theatre and religious ecstasy in ancient Greek religion and myth.
 Wine played an important role in Greek culture, and the cult of Dionysus was the main religious focus for its unrestrained consumption.
 His worship became firmly established in the seventh century BC.
 He may have been worshipped as early as c. 1500–1100 BC by Mycenean Greeks; traces of Dionysian-type cult have also been found in ancient Minoan Crete.
 His origins are uncertain, and his cults took many forms; some are described by ancient sources as Thracian, others as Greek.
 In some cults, he arrives from the east, as an Asiatic foreigner; in others, from Ethiopia in the South.
 He is a god of epiphany, "the god that comes", and his "foreignness" as an arriving outsider-god may be inherent and essential to his cults.
 He is a major, popular figure of Greek mythology and religion, becoming increasingly important over time, and included in some lists of the twelve Olympians, as the last of their number, and the only god born from a mortal mother.
 His festivals were the driving force behind the development of Greek theatre.
Cabernet blanc is a white German and Swiss wine grape variety that is a crossing of the French wine grape Cabernet Sauvignon and an unknown hybrid grape variety.
 The grape was bred by Swiss grape breeder Valentin Blattner in 1991.
 Cabernet blanc has strong resistance to most grape disease including botrytis bunch rot, downy and powdery mildew and tends to produce loose clusters of small, thick-skinned grape berries which can hang on the vine late into the harvest season to produce dessert wines. Today the grape is found primarily in the Palatinate wine region of Germany with some experimental plantings in the Netherlands.
Grechetto or Grechetto bianco is a white Italian wine grape variety of Greek origins.
 The grape is planted throughout central Italy, particularly in the Umbria region where it is used in the "Denominazione di origine controllata" (DOC) wine Orvieto.
 It is primarily a blending grape, though some varietal wine is also produced.
 Grechetto is commonly blended with Chardonnay, Malvasia, Trebbiano and Verdello.
 The grape's thick skin provides good resistance to downy mildew which can attack the grape late in the harvest season.
 This makes Grechetto a suitable blending grape in the production of "Vin Santo".
Petit Manseng (sometimes translated: Small Manseng, rarely "Little Manseng") is a white wine grape variety that is grown primarily in South West France.
 It produces the highest quality wine of any grape in the Manseng family.
 The name is derived from its small, thick skin berries.
 Coupled with the small yields of the grapevine, most Petit Manseng farmers produce around 15 hl of wine per hectare.
 The grape is often left on the vine till December to produce a late harvest dessert wine.
 The grape is grown primarily in Gascony, Jurançon and Pacherenc du Vic-Bilh but has recently drawn interest in New World wine regions like California, North Georgia, Virginia, Ohio, and Australia.
 The reason is that it is expected to follow Viognier's path to popularity among white wine drinkers.
 It was already present in Uruguay, when Basque settlers brought "Manseng" and Tannat vines with them to their new home.
 Despite being easily recognizable as a white grape while true Manseng is a black grape, wine that is Petit Manseng is still normally labeled as just "Manseng".
 The grape is often left on the vine to produce a late harvest wine made from its nearly raisin like grapes.
Enologix is a privately held California corporation that designs predictive analytics for luxury winegrowing.
 The company sells grape and wine quality indices, models, software and consulting products.
 Enologix created the first algorithms that predict grape harvest dates, grading new wines, digital blends, and future market price, volume and taste scores.
 The most important metric among winemakers are digital blends and a taste index which predicts 100-point scores of consumer critics such as Robert Parker.
 It claims that the quality of wine can be measured chemically, and a score assessed, much like a wine critic.
 Clients include Beaulieu, Cakebread Cellars, Diamond Creek, Ridge Vineyards.
 Enologix's metrics have been correlated with market performance metrics, including 100-points critics' scores.
Two ships of the Royal Navy have been named HMS "Ethalion" after Ethalion, a mythical Greek sailor transformed into a dolphin for attempting to abduct Dionysus, whilst another was planned:
Arctic exploration is the physical exploration of the Arctic region of the Earth.
 It refers to the historical period during which mankind has explored the region north of the Arctic Circle.
 Historical records suggest that humankind have explored the northern extremes since 325 BC, when the ancient Greek sailor Pytheas reached a frozen sea while attempting to find a source of the metal tin.
 Dangerous oceans and poor weather conditions often fetter explorers attempting to reach polar regions and journeying through these perils by sight, boat, and foot has proven difficult.
The Apple & Grape Harvest Festival was born out of the Apple Blossom Festival in 1966, itself born of the "Back To Stanthorpe Week" celebrations in 1954.
Nikos Kavvadias (Greek: Νίκος Καββαδίας ; January 11, 1910 in Nikolsk-Ussuriysky – February 10, 1975 in Athens) was a Greek sailor, poet and writer; he used his travels around the world as a sailor, and life at sea and its adventures, as powerful metaphors for the escape of ordinary people outside the boundaries of reality.
The Grape Harvest or Autumn (Spanish: "La vendimia o El Otoño" ) is a 1786 oil on canvas painting by Francisco Goya which depicts a man in autumn-colored clothes with his wife and son.
 A peasant is presenting them with a sample of the year’s grape harvest.
 The piece has been held by the Museo del Prado in Madrid since 1870.
