Campi Flegrei DOC

Campi Flegrei's winemaking tradition is traced to ancient Greek settlement around 700 BCE, when colonists established vineyards across this volcanically active peninsula. In Roman times, local wines gained considerable prestige; Pliny the Elder celebrated the vino colombino of Puteoli, modern-day Pozzuoli, possibly vinified from the Piedirosso grape still grown today. During the Middle Ages, the wines of Pozzuoli retained their reputation, documented in the account book known as the 'Liber espensarum,' which records that they were served at the table of King Charles II of Anjou. The 19th-century phylloxera epidemic that devastated European viticulture could not take hold in the region's sandy volcanic soils, preserving ungrafted centenarian vines that remain productive today. DOC recognition in 1994 formalized a revival of commercial winemaking after decades of urban pressure and volcanic instability.

• Winemaking origins traced to Greek colonists around 700 BCE; Roman writer Pliny the Elder praised local wines from Puteoli (modern Pozzuoli)
• Medieval prestige documented in the 'Liber espensarum' account book; wines served to King Charles II of Anjou
• Phylloxera could not survive in sandy volcanic soils during the 19th century, preserving ungrafted vines; DOC formalized in 1994

Campi Flegrei DOC covers seven municipalities: Bacoli, Marano, Monte di Procida, Naples, Pozzuoli, Quarto on the mainland, plus the island of Procida. The entire zone lies within the Phlegrean Fields, a large volcanic caldera west of Naples comprising 24 craters and edifices, many of which lie underwater in the Gulf of Pozzuoli, spread across more than 65 square kilometres. Vineyards sit at a general altitude of 150 to 200 metres above sea level, on terrain shaped by multiple geological periods of eruption. The Mediterranean climate brings warm, dry summers and mild winters moderated by Tyrrhenian Sea breezes, which also impart a subtle salinity to the grapes. Soils are a pyroclastic patchwork of gray and yellow tuff, lapilli, and pumice, whose sandy, porous texture provides excellent drainage while enabling moisture retention for vines during summer drought.

• Seven communes: Bacoli, Marano, Monte di Procida, Naples, Pozzuoli, Quarto, and the island of Procida; caldera extends over 65 square kilometres with 24 craters
• Vineyards generally between 150 and 200 metres above sea level; Mediterranean climate with warm summers and mild winters tempered by sea breezes
• Soils composed of gray and yellow tuff, lapilli, and pumice; sandy volcanic texture ensures drainage and resists phylloxera
• Ongoing bradyseism (ground uplift and subsidence) and geothermal features, including active fumaroles, define the living landscape

Falanghina is the dominant white grape, and research has confirmed two distinct biotypes: Falanghina Flegrea, the local clone known for lean, salty, mineral character, and Falanghina Beneventana, a genetically distinct variety from northeastern Campania considered less suited to this terroir by local producers. Bianco blends require 50-70% Falanghina with 10-30% Biancolella and/or Coda di Volpe, plus up to 30% other local white varieties. Varietal Falanghina must contain at least 90% of the grape. Piedirosso (also known locally as Per e Palummo, meaning red feet of the dove) is the lead red variety, producing light, juicy wines with soft tannins, red berry fruit, and spice. Rosso blends call for 50-70% Piedirosso supported by 10-30% Aglianico and/or Sciascinoso and up to 30% other local red varieties. Varietal Piedirosso requires 90% of the grape. Dry and passito (sweet dried-grape) styles of Piedirosso are both permitted. Falanghina Spumante is also a recognised style within the DOC.

• Falanghina Flegrea: lean, salty, mineral local biotype; Falanghina Beneventana is genetically distinct and not considered authentic for this zone
• Bianco blend: 50-70% Falanghina, 10-30% Biancolella and/or Coda di Volpe, up to 30% other local whites; varietal requires 90% Falanghina
• Rosso blend: 50-70% Piedirosso, 10-30% Aglianico and/or Sciascinoso, up to 30% other local reds; varietal requires 90% Piedirosso
• Passito (sweet) and Spumante styles are permitted within the DOC alongside standard dry whites and reds

The defining viticultural feature of Campi Flegrei is its phylloxera-free volcanic soils, which allow ungrafted vines to remain on their original rootstock. The sandy, pyroclastic composition of ash, pumice, lapilli, and tuff proved inhospitable to the phylloxera insect that devastated European vineyards in the late 19th century. Pumice in the soil retains subsurface moisture, sustaining vines through Mediterranean summers. Ungrafted centennial vines achieve full ripeness at lower alcohol levels than grafted counterparts, and produce wines with intense mineral and saline character. Vines are traditionally trained alla putuelana (also known as the Pozzuoli style), in which canes are supported by wooden stakes, a method documented since Roman times. The fragmented urban vineyard landscape, with plots interspersed among apartment buildings and nature reserves inside volcanic craters, makes mechanisation impossible and restricts holding sizes, so all work is done by hand.

• Phylloxera failed to establish in sandy volcanic soils during the 19th-century epidemic; ungrafted centennial vines still producing today
• Pumice in soil retains moisture below the surface, enabling vine survival during Mediterranean droughts
• Traditional alla putuelana (Pozzuoli-style) vine training on wooden stakes documented since Roman times
• Urban and crater-rim vineyard plots prevent mechanisation; all harvesting and canopy work done by hand

The Campi Flegrei DOC was established in 1994, covering seven communes with soils of volcanic pyroclastic origin. Yield limits are set at 12 tonnes per hectare for red grape varieties and 13 tonnes per hectare for white grape varieties. Finished wines must reach a minimum alcohol level of 11.5% for reds and 10.5% for whites. Varietal-labelled wines, whether Falanghina or Piedirosso, must contain at least 90% of the named variety and be fermented to at least 12% ABV for reds and 11% for whites. The DOC recognises Bianco, Falanghina (including Spumante), Rosso, and Piedirosso (including dry and passito styles) as its main wine types. No mandatory wood aging applies to any style, and there are no Superiore or Riserva tiers formally attached to the Bianco or Rosso designations, keeping the focus on fresh, mineral-driven expression.

• Yields capped at 12 t/ha for reds and 13 t/ha for whites; minimum ABV 11.5% for reds and 10.5% for whites in blends
• Varietal wines (Falanghina, Piedirosso) require 90% of the named variety and higher minimum ABV: 12% for reds, 11% for whites
• Permitted styles: Bianco, Falanghina, Falanghina Spumante, Rosso, Piedirosso (dry and passito); no mandatory wood aging
• Rosso blend = 50-70% Piedirosso, 10-30% Aglianico and/or Sciascinoso, up to 30% other local reds

Campi Flegrei is one of Europe's most geologically active inhabited landscapes. The caldera contains 24 craters and volcanic edifices, many submerged beneath the Gulf of Pozzuoli, and ongoing bradyseism causes measurable ground uplift and subsidence. The Macellum of Pozzuoli, long misidentified by 18th-century excavators as a temple of Serapis, shows dramatic bradyseismic evidence: marine mollusc boreholes on its marble columns prove the site has cycled above and below sea level repeatedly. The last confirmed eruption in the caldera, in 1538, created the Monte Nuovo tuff cone in eight days. The region is also notable for having the second-highest concentration of grapevines in any major world city, behind only Vienna, a legacy of medieval noble families who maintained vineyard holdings close to Naples. Several craters, including Astroni, are protected nature reserves where vines grow on crater slopes. Most of the roughly 23 producers receive visitors by appointment.
