Euzhan Palcy is a film director, writer and producer from Martinique, French West Indies.
 She is notable for being the first black woman director produced by a major Hollywood studio (MGM), for "A Dry White Season", as well as being the only woman filmmaker to have directed Marlon Brando, whom she brought back to the screen after a gap of nine years.
 Palcy is the first black director (male or female) to direct an actor to an Oscar nomination and the first black director to win a César Award, the highest French film award.
 She is also the first black director to win of a Venice Film Festival Award (Silver Lion).
Montrachet is an "Appellation d'origine contrôlée" (AOC) and Grand Cru vineyard for white wine from Chardonnay in the Côte de Beaune subregion of Burgundy.
 It straddles the border between the two communes of Chassagne-Montrachet and Puligny-Montrachet and produces what many consider to be the greatest dry white wine in the world.
 It is surrounded by four other Grand Cru vineyards all having "Montrachet" as part of their names.
 Montrachet itself is generally considered superior to its four Grand Cru neighbours, as reflected in its higher price.
Aligoté is a white grape used to make dry white wines in the Burgundy region of France.
 It is also cultivated in eastern European countries such as Romania, Russia, Ukraine, Moldova, and Bulgaria.
 With 45000 ha , it was the 22nd most planted vine variety in the world in 2004.
 The wine was first recorded in Burgundy in the 18th century.
Robert Oxton Bolt, CBE (15 August 1924 – 21 February 1995) was an English playwright and a two-time Oscar-winning screenwriter, known for writing the screenplays for "Lawrence of Arabia", "Doctor Zhivago" and "A Man for All Seasons", the latter two of which won him the Academy Award for Best Adapted Screenplay.
Jacquère is a variety of white grape found primarily in the Savoy wine region of France.
 It is a high-yielding vine variety which is used to produce lightly scented, rather neutral dry white wine, such as Vin de Savoie.
 Jacquère is the grape used in Apremont wines and is the usual wine paired with cheese fondue (a dish from the same region).
 It is also found in Bugey wines.
Jurançon is a wine region in South West France in the foothills of the Pyrenees, around the commune of Jurançon.
 It produces a dry white wine and a more sought after sweet white wine.
 The grape varieties used are Gros Manseng, Petit Manseng and Courbu.
 The sweet wines develop aromas of tropical fruit such as pineapple and mango.
 The vines are grown on steep mountain slopes and for the sweet wines the grapes are often hand selected well into October and November to ensure the best noble rot characteristics - although Tim Wildman MW states that noble rot is not the origin of sweetness in these wines.
Austrian wines are mostly dry white wines (often made from the Grüner Veltliner grape), though some sweeter white wines (such as dessert wines made around the Neusiedler See) are also produced.
 About 30% of the wines are red, made from Blaufränkisch (also known as Lemberger, or as Kékfrankos in neighbouring Hungary), Pinot noir and locally bred varieties such as Zweigelt.
 Four thousand years of winemaking history counted for little after the "antifreeze scandal" of 1985, when it was revealed that some wine brokers had been adulterating their wines with diethylene glycol.
 The scandal destroyed the market for Austrian wine and compelled Austria to tackle low standards of bulk wine production, and reposition itself as a producer of quality wines.
 The country is also home to Riedel, makers of some of the most expensive wine glasses in the world.
 Some of the best producers of Austria include Weingut F.X. Pichler and Weingut Franz Hirtzberger, Weingut Hutter, Weingut Eigl and Wellanschitz.
A Dry White Season is a 1989 American drama-historical film directed by Euzhan Palcy and starring Donald Sutherland, Jürgen Prochnow, Marlon Brando, Janet Suzman, Zakes Mokae and Susan Sarandon.
 It was written by Colin Welland and Euzhan Palcy, based upon André Brink's novel of the same name.
 Robert Bolt also contributed uncredited revisions of the screenplay.
 It is set in South Africa in 1976 and deals with the subject of apartheid.
 Brando was nominated for the Academy Award for Best Supporting Actor.
The navy bean, haricot, pearl haricot bean, boston bean, white pea bean, or pea bean, is a variety of the common bean ("Phaseolus vulgaris") native to the Americas, where it was domesticated.
 It is a small, dry white bean which is smaller than many other types of white beans, and has an oval, slightly flattened shape.
 It features in such dishes as baked beans, and even pies, as well as in various soups such as Senate bean soup.
 Unlike most canned vegetables, which lose much of their nutritive value in the canning process, navy beans maintain their nutritive value when canned.
A Dry White Season (Afrikaans: "’n Droë wit seisoen " ) is a 1979 novel by Afrikaner novelist André Brink.
 The novel focuses on the death during detention of a black activist.
 The novel challenges Apartheid, depicting the slow transformation of a ruling class Afrikaner to opposition to the regime.
 The novel was initially banned in South Africa; though under this ban, Brink published 3000 copies published in an underground.
