epidemic of the late 19th century, eventually reducing Zinfandel to just nine vines of locally-known "Crljenak Kaštelanski" discovered in 2001 on the Dalmatian coast of Croatia. The first documented use of the term ''Primitivo'' appears in Italian governmental publications of the 1870s. The name derives from the terms ''primativus'' or ''primaticcio'', which refer to the grape's tendency to ripen earlier than other varieties. This name's appearance, 40 years after the first documented use of the term ''Zinfandel'', was previously thought to suggest that Primitivo was introduced to Italy from across the Atlantic; however, this hypothesis has become unlikely since the discovery of the vine's Croatian origin. Primitivo is now thought to have been introduced as a distinct clone into Italy's

) from Austria's Thermenregion. Gibbs visited Boston in 1830, and Samuel Perkins of that city began selling "Zenfendal" soon afterward. In 1830, Gibbs also supplied Prince with "Black St. Peters," a similar variety that may have come from England, where many vines have "St. Peters" in their names. Little is known about this vine, except that the Black St. Peters that arrived in California in the 1850s was the same as what became known as Zinfandel by the 1870s. By 1835 Charles M. Hovey, Boston's leading nurseryman, was recommending "Zinfindal" as a table grape. It was soon widely grown in heated greenhouses to produce table grapes as early as June. The first reference to making wine from "Zinfindal" appears in John Fisk Allen's ''Practical Treatise in the Culture and Treatment of the Grape Vine'' (1847). Meanwhile, the fad of hothouse cultivation faded in the 1850s as attention turned to the

in the 1850s and took Zinfandel with them. Prince's notebook records that the grape dried "perfectly to Raisin" and that he believed his Zinfandel was the same as the "Black Sonora" he found in California. When the vine known as "Black St. Peters" arrived in California, it was initially regarded as a distinct variety, but by the 1870s, it was recognized as the same grape as Zinfandel. Sacramento nurseryman A.P. Smith listed "Black St. Peter's" among the 24 grape varieties he was propagating in a sales catalog in 1856 and he exhibited "Zeinfindall" at the state fair in 1858. Joseph W. Osborne planted Zinfandel from Macondray at his Oak Knoll vineyard just north of Napa, and his wine was much praised in 1857. Planting of Zinfandel boomed soon after, and by the end of the 19th century, it was the most widespread variety in California. These Zinfandel

. Many vineyards that survived by supplying the home market were located in California's Central Valley, a non-optimal environment for growing quality Zinfandel. Thus, the end of Prohibition left a shortage of quality wine grapes, and Zinfandel sank into obscurity as most was blended into undistinguished fortified wines. However, some producers remained interested in making single

White Zinfandel became immensely popular. White Zinfandel still accounts for 9.9% of U.S. wine sales by volume (6.3% by value), six times the sales of red Zinfandel. Most white Zinfandel is made from grapes grown for that purpose in California's Central Valley. Wine critics considered white Zinfandel to be insipid and uninteresting in the 1970s and 1980s, although modern white Zinfandels have more fruit and less cloying sweetness.

. In 1993, Meredith used a DNA fingerprinting technique to confirm that Primitivo and Zinfandel were clones of the same variety. Comparative field trials have found that "Primitivo selections were generally superior to those of Zinfandel, having earlier fruit maturity, similar or higher yield, and similar or lower bunch rot susceptibility." This is consistent with the theory that Primitivo was selected as an early-ripening clone of a Croatian grape. By 1998, Meredith's team realized that Plavac Mali was ''not'' Zinfandel, but that one was the parent of the other. In 2000 they discovered that Primitivo/Zinfandel was one parent of Plavac Mali.

Viticulture and winemaking

Zinfandel vines are quite vigorous and grow best in warm but not too hot climates because grapes may shrivel in hot weather. Zinfandel's thin-skinned grapes grow in large, tight bunches that are sometimes prone to bunch rot. The fruit ripens reasonably early and produces juice with high sugar content. If weather conditions permit, the grapes may be late harvest wine, late-harvested to make

. Zinfandel is often praised for its ability to reflect both its ''terroir'' and its winemaker's style and skill. The grapes exhibit an uneven pattern of ripening: a single bunch may contain both raisin-like, over-ripe grapes, and green, unripened grapes. Some winemakers choose to vinify the bunches with these varying levels of ripeness, while others hand-harvest (wine), harvest the bunches, even by single berries, in multiple passes through the vineyards over several weeks. This extensively laborious practice is one component of the high cost of some Zinfandels. Red Zinfandel wines have been criticized for being too "hot" (too alcoholic), although modern winemaking techniques have helped make them more approachable. On the other hand, Zinfandel producers such as Joel Peterson of Ravenswood believe that alcohol-removing technologies, such as reverse osmosis and spinning cones, remove a sense of terroir from the wine. If a wine has the tannins and other components to balance 15% alcohol, Peterson argues, it should be accepted on its terms. Factors that affect the wine's flavors include the length of fermentation, length of the maceration (wine), maceration period with skin contact, the level of oak aging, and the degrees Brix of the harvested grapes. White Zinfandel is normally harvested early at 20°Bx when the grapes have yet to develop much Typicity, varietal character, though some examples can develop hints of tobacco and apple skin. At 23°Bx (the degree that most red wine is considered "ripe"), strawberry flavors develop. Cherry flavors appear at 24°Bx followed by blackberry notes at 25°Bx.
