Jars of Clay is a Christian rock band from Nashville, Tennessee.
 They met at Greenville College in Greenville, Illinois.
Black Spanish is now known to be a seedling of an American hybrid grape resulting from a cross of the American "Vitis aestivalis" species of grape with an unknown "Vitis vinifera" pollen donor.
 This hybridization is not known to have been purposeful, and may have occurred naturally, as was the case with many of the early American grape cultivars.
 Recently, it was revealed from the microsatellite DNA (a.k.a. Simple Sequence Repeats or SSRs) analyses conducted on various 'Jacquez cultivars' by Dr Jerry Rodrigues that at least two of the European accessions (grapevine collections) which are presently curated in Europe were originally derived from the oldest known Jacquez cultivar (the Madeira Jacquez).
 The original American hybrid grape parent had found its way to the Madeira Islands early in the 18th century (where it was called Jaquez or Jacquet) and thence to France.
 Lenoir is another such seedling similar to Black Spanish which was propagated by Herbemont.
 Many other historical names appeared on the scene throughout the early history of these Jacquez seedlings such as Jack, Blue French, Ohio, and El Paso, among others.
 For example, Herbemont tells us that he received Lenoir seeds from a man named Lenoir who cultivated it near Stateburg SC, in the vicinity of the Santee River sometime in the 18th Century.
 Lenoir made its way to Texas early, where it even took on the names El Paso and Black Spanish.
 From its wild South Carolina parent, Lenoir (and also Black Spanish) carries natural resistance to the Phylloxera pest, as well as to the deadly Pierce's Disease, which is a common threat to "Vitis vinifera" vineyards in warm winter areas of the United States.
 Lenoir was also one of the American vines which the grape breeder Thomas Volney Munson experimented with in the late 19th Century in Denison, Texas.
 Prior to its use by Munson, Lenoir was grown and used in wine by Nicholas Herbemont of Columbia, South Carolina in the 1830s, though to a lesser extent than the similar, lighter-skinned variety "Warren" ("Brown French") which become known as Herbemont because of his promotion of that variety.
 Lenoir was introduced to Europe in the mid-19th Century, where French vintners were intrigued by its similarity to European "Vitis vinifera" winegrapes, and gave it the names Jacquez and Jacquet.
 It became an important direct producing grape in Europe during the phylloxera crisis, and later was used to some extent as a rootstock to protect the classic vinifera grapes from phylloxera.
 Ulysses P. Hedrick's famous "Grapes of New York" in 1908 provides the seminal discussion of Lenoir and many of the early North American grapes.
Black Grape are a rock band from England, featuring former members of Happy Mondays and Ruthless Rap Assassins.
 Their musical style fuses funk and electronic rock with electronic programming and samples.
Mark Berry (born 18 April 1964), known professionally by his stage name Bez, is an English percussionist, author, dancer, media personality and comedian.
 He is a member of the rock bands Happy Mondays and Black Grape and plays the maracas.
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.
Morellino di Scansano DOCG is an Italian red wine made in the hilly environs of the village of Scansano, GR, in the Maremma region of coastal Tuscany, which has an ancient but obscure tradition of winemaking.
 Morellino is the local name for the Sangiovese grape variety.
 Many people think that the name "Morellino" comes from "morello" (brown), the colour of the region's horses.
 The name may also come from the morello cherry, a dark red cherry with great tartness and acidity.
 The wine, which was granted DOC status in 1978, then upgraded to DOCG status beginning with the 2007 vintage, is made from at least 85% Sangiovese, which is also the basis of the Tuscan wines Chianti, Brunello di Montalcino, and Vino Nobile di Montepulciano.
 The remaining 15% can comprise any non-aromatic black grape varieties included in a list made and periodically updated by Tuscan wine authorities.
Black Grape Global is a London-based artist and entertainment management company.
 Black Grape's founder attended Kingston University and organised events there, and for other universities in the United Kingdom.
The Sumoll is a black grape variety, although there is also a white strain.
 It is a rustic variety, native from the Penedès region in Catalonia (EU), drought resistant and with uniform development.
 The grape is long and big.
 It is used to produce red, white, rosé wines and cava (Catalan form of Champagne, the so-called Traditional Method).
 Its former presence is also evident in the number of different names in Catalan dialects: sumoi, chimoi, saumoll, somoi, sumoy, ximoll, somoll, ximoy, xemoll, among others.
Daniel Paul "Dan" Haseltine (born January 12, 1973) is an American singer best known as lead vocalist for Christian alternative folk rock group Jars of Clay.
 Haseltine has performed vocals, piano, accordion, percussion and most recently, melodica, while with Jars of Clay.
 He has had different artistic titles, including songwriter, producer, film composer, music supervisor and art designer.
Vernaccia is a white wine grape that is found in many Italian wines but is most commonly associated the Tuscan wine Vernaccia di San Gimignano.
 Ampelographers have determined that the Vernaccia vine has many clonal varieties but is unrelated to some Italian vines known as "Vernaccia" such as the Sardinian varieties used in the Sherry-like wine "Vernaccia di Oristano", the Trentino-Alto Adige/Südtirol red wine grape known as Vernatsch or the black grape used in the red sparkling wine of the Marche "Vernaccia di Serrapetrona".
 A possible reason for this is that the root of the name Vernaccia translates to "vernacular" and can apply to any local grape.
