Description of the Zinfandel (Primitivo) grape variety, characteristics of yield and frost resistance

The vigorous plant has established itself with excellent yield and ease of maintenance. Zinfandel grapes are capable of growing in various climatic conditions. In hot climates, the berries ripen remarkably, and often grape stepchildren delight with a second harvest. The variety is widely used for the production of a variety of wines. There are vineyards in California that have been producing abundant Zinfandel berries for over 80 years.

A bit of history

In 1820, Gibbs, an amateur gardener, ordered several types of vines from the Schönbrunn Imperial Garden, among which was a prolific black variety from Hungary. The gardener had high hopes for this variety. After the death of Gibbs, William Robert Prince began selling Zinfandel vines in his nursery in 1832.

In 1850, the variety gained popularity as a red wine. After 12 years the product was tasted by the French winemaker Foret, who highly appreciated the drink. Since then, Zinfandel has spread throughout California.

What is this variety?

In the 1960s, the phytopathologist Goin saw similarities between Zinfandel and the Primitivo grape in Apulia. In the 70s, the identity of the varieties was proved using isozyme analysis.

Thanks to this, Apulian producers, taking advantage of the popularity of their overseas counterpart, began to label Primitivo wine for export as Zinfandel.

Through research, it has been proven that clones of the same variety are:

  • the American Zinfandel;
  • Italian Primitivo;
  • Croatian Crljenak.
