Pre-Phylloxera Vines

The phylloxera crisis stands as the most destructive event in the history of viticulture. The microscopic, pale yellow aphid Daktulosphaira vitifoliae, native to eastern North America, arrived in Europe in the late 1850s when Victorian botanists imported American vine specimens. Vitis vinifera, the European species behind virtually all quality wine, had evolved with no defenses against the pest. Phylloxera feeds on vine roots, injecting venom that causes deformations and invites secondary fungal infections, gradually cutting off the flow of water and nutrients until the vine dies. It was first recorded in France in 1863 in the southern Rhone region and spread rapidly, reaching Provence and Bordeaux by 1870. Over the following decades between two-thirds and nine-tenths of all European vineyards were destroyed. The economic consequences were catastrophic: wine production in France fell from 41 million to 23 million hectolitres over roughly three decades. Desperate growers tried flooding vineyards for 40 days, injecting carbon disulfide into soil, and various folk remedies before scientists Jules-Emile Planchon and Charles Valentine Riley confirmed that grafting Vitis vinifera scions onto resistant American rootstocks was the only effective solution. This practice, known in France as the Reconstitution, reshaped every aspect of how vines are grown worldwide.

• Phylloxera was first recorded in France in 1863 in the Languedoc, having arrived from North America with imported American vine specimens in the late 1850s.
• The pest causes root deformations called nodosities and tuberosities on Vitis vinifera, leading to fungal infection and vine death within two to three years.
• France's wine production fell from 41 million to 23 million hectolitres over the epidemic period; Bordeaux alone saw 100,000 of its 170,000 hectares affected.
• Grafting onto American rootstocks (principally Vitis rupestris and Vitis riparia) proved the only reliable solution; Bordeaux producers accepted the practice in 1881 and Burgundy in 1887.

Not all vineyards fell to phylloxera. The spread of the epidemic was gradual and uneven, and certain natural conditions prevented the pest from establishing itself. Sandy soils are the best-documented barrier: phylloxera larvae cannot move effectively through the loose, abrasive particles and find the substrate largely uninhabitable. This is why areas such as Jumilla in southeastern Spain, Toro and parts of Rueda, the Mediterranean coast of France near Listel, and the sandy beaches of Provence's Bouches-du-Rhone retained ungrafted vines. Altitude above roughly 1,000 metres creates extreme temperature fluctuations that make it difficult for the insect to survive, protecting vineyards in the Valle d'Aosta and parts of the Alps. The Mosel's steep slate soils proved similarly hostile, leaving Riesling vines ungrafted to this day. Volcanic soils, particularly the silica-rich ash of Mount Etna and Santorini, are associated with surviving ungrafted plantings, though the exact mechanism remains debated among scientists. Waterlogging also kills phylloxera, which cannot survive in flooded conditions, explaining some survivors along river banks. Geographic isolation protected entire wine countries: Chile remains largely phylloxera free, enclosed by the Atacama Desert, the Pacific Ocean, and the Andes, while much of South Australia, Western Australia, and Tasmania have never been infected. In a few cases, the survival of individual plots is simply unexplained, a mystery that adds to their mystique.

• Sandy soils are the most reliable natural barrier: phylloxera larvae cannot move through loose sand, protecting vineyards in Jumilla (Monastrell), Toro, Colares (Portugal), and coastal France.
• Altitude above 1,000 metres (as in Valle d'Aosta and parts of Sicily's Etna) creates temperature extremes that prevent phylloxera from surviving through the seasons.
• Slate soils in the Mosel remain hostile to phylloxera, leaving ungrafted Riesling plots intact; the German term for ungrafted is wurzelecht.
• Geographic isolation explains phylloxera-free wine countries: Chile is protected by the Atacama Desert, the Andes, and the Pacific; much of Australia's key wine regions remain uninfected and maintain biosecurity exclusion zones.

A small number of pre-phylloxera vineyards have achieved legendary status, their wines functioning as living archives of a vanished viticultural world. Bollinger's Vieilles Vignes Françaises (VVF) is perhaps the most celebrated example in Europe. Made from ungrafted Grand Cru Pinot Noir plots in Ay, Champagne, the cuvee was first produced in 1969 after English wine writer Cyril Ray suggested vinifying a special wine from Bollinger's surviving plots. The vines are reproduced by provignage, a traditional layering technique, and are tended entirely by hand. In 2004, phylloxera destroyed the third plot, Croix Rouge in Bouzy, leaving only Clos Saint-Jacques and Chaudes Terres in Ay, totaling roughly 36 ares. Production is tiny, typically between 2,000 and 5,000 bottles per declared vintage. At Quinta do Noval in the Douro, the Nacional parcel covers approximately 2.5 hectares of ungrafted native varieties planted on their own roots, surrounded by grafted vines on identical schist soils. Its name reflects the fact that the vines grow in Portuguese soil on Portuguese rootstock, attached directly to the soil of the nation. Only 200 to 300 cases are produced in declared years, and the Nacional does not follow the same rhythm as the rest of the estate, sometimes performing brilliantly in years when no other vintage is declared. In Italy, the Lisini estate in Montalcino has maintained a half-hectare of ungrafted Sangiovese with vines dating to the mid-1800s, producing a wine called Prefillossero since 1985. On Mount Etna, pre-phylloxera alberello (bush-trained) vines at 600 to 1,000 metres elevation produce intensely distinctive wines from Nerello Mascalese.

• Bollinger's Vieilles Vignes Françaises, first produced in 1969, is a Blanc de Noirs from two surviving ungrafted Grand Cru Pinot Noir clos in Ay; production is typically 2,000 to 5,000 numbered bottles per vintage.
• Quinta do Noval Nacional is produced from a 2.5-hectare parcel of ungrafted vines in the Douro, yielding only 200 to 300 cases per declared year; the vines are identified by smaller trunks and berries giving a higher skin-to-juice ratio.
• The Lisini estate in Montalcino has produced Prefillossero from a half-hectare of ungrafted mid-1800s Sangiovese since 1985.
• Mount Etna's pre-phylloxera alberello vines sit at 600 to 1,000 metres on the northern slope and are among the most sought-after new releases each vintage from producers such as Terre Nere and Pietradolce.

The question of whether pre-phylloxera, ungrafted vines produce fundamentally superior wine is one of the most enduring and unresolved debates in the wine world. Proponents argue that grafting creates an interruption in sap flow at the graft union, filtering or altering the vine's ability to express its precise terroir. Loic Pasquet of Liber Pater, who plants ungrafted own-rooted vines in Bordeaux with historic varieties to recreate pre-1855 Classification wines, argues that grafting produces varietal wines rather than true vins de terroir, because the American rootstock allows vines to be planted in conditions unsuited to the variety. Wine critic Allen Meadows, with extensive experience of pre-phylloxera Burgundy from old bottles, says the difference is primarily textural: a different density and weight, and tannins with a different quality, though he acknowledges difficulty separating the grafting variable from vine age and density. Christophe Baron of Cayuse in Walla Walla, who compares own-rooted and grafted examples of the same varieties on identical soils, describes the ungrafted wines as having a smooth, velvety mouthfeel, while his grafted wines show more tension and grip. Mosel producer Nik Weis speaks of a homogenous structure in ungrafted vines, undisturbed by a grafting cut. However, skeptics including Master of Wine Sarah Abbott note the difficulty of isolating the grafting variable from vine age, massal selection, and farming practice. The scientific literature has not yet definitively resolved the question, making it an active and commercially important area of debate.

• The primary sensory difference reported by tasters and winemakers comparing grafted and ungrafted wines is textural: ungrafted vines are described as producing smoother, more velvety mouthfeel, while grafted wines show more tension and grip.
• Loic Pasquet (Liber Pater, Bordeaux) argues that American rootstocks allow vines to be planted in terroir unsuited to the variety, producing varietal rather than terroir-driven wines.
• Domaine de la Romanee-Conti maintained ungrafted vines in the Côte d'Or until 1945, when yields fell to 2.5 hectolitres per hectare before the estate accepted grafting onto American rootstock.
• Mélanie Tarlant (Champagne) reports that blind tasters identify her ungrafted Chardonnay wine at a 100 percent hit rate when compared with base wines from grafted plots in the same area, suggesting a perceptible difference.

While surviving pre-phylloxera plots remain precious and irreplaceable, a small but growing movement of producers is deliberately planting new ungrafted vineyards, accepting significant risk in pursuit of what they believe is a truer expression of variety and site. This movement is associated with the term francs de pied (literally free-footed in French), equivalent to the Italian piede franco and the German wurzelecht. In 2021, Loic Pasquet founded a formal international association called Francs de Pied, dedicated to preserving existing ungrafted vineyards and encouraging new plantings in phylloxera-resistant terroirs. Producers working in this space include Teobaldo Cappellano in Barolo with his Otin Fiorin Pie Franco, Terence Courbe of Plaimont Producteurs with an ungrafted Tannat plot in Saint Mont planted in 1871, and various producers on Etna and Santorini. In the New World, Resonance (Maison Louis Jadot's Oregon project) farms 19 acres of ungrafted Pinot Noir, while Washington State remains largely own-rooted by default given the hostile conditions phylloxera faces there. The risks are real: phylloxera is still active in most wine regions globally, and planting ungrafted vines in clay-heavy soils invites vine death. Biosecurity experts caution that widespread adoption would create dangerous reservoirs of phylloxera that could undermine resistance in adjacent grafted vineyards. For exam candidates, the key distinction is between historically surviving pre-phylloxera vines (the product of soil or climate protection) and newly planted own-rooted vines (a deliberate agronomic choice with acknowledged risk).

• The French term francs de pied (free-footed) refers to ungrafted vines on their own roots; equivalents are piede franco in Italian and wurzelecht in German.
• In 2021, Loic Pasquet founded the Francs de Pied association to preserve existing ungrafted vineyards and encourage new plantings in phylloxera-resistant sandy, volcanic, or shale soils.
• Loic Pasquet identifies soils with more than 4 percent clay as inevitably colonized by phylloxera; sand, shale, and volcanic soils offer the best protection for ungrafted plantings.
• Washington State remains largely ungrafted by default: the combination of harsh winters, arid climate, and low soil moisture creates conditions hostile to phylloxera survival, though the pest has been detected in the Walla Walla area.

Pre-phylloxera vines are rarely identified consistently on labels, making it important for students and professionals to understand the range of terms in use. In France, a producer may use vieilles vignes (old vines) without specifying whether the vines are grafted or ungrafted, since the term has no legal definition in most appellations. The specific designation vignes prephylloxeriques (pre-phylloxera vines) is occasionally used, as with Plaimont's Tannat in Saint Mont. Bollinger uses Vieilles Vignes Françaises (old French vines) to signal the ungrafted status. In Italy, piede franco and prefillossero are the clearest indicators. In Germany, wurzelecht is the technical term, though many producers simply label their ungrafted wines as Alte Reben (old vines). On Etna, wines are increasingly labeled with the designation prephylloxera or with reference to the contrada (vineyard district) and vine age to signal their ungrafted status. It is important to note that old vine designations do not imply pre-phylloxera status: a vine planted in 1950 in Barossa Valley on its own American rootstock is an old vine, not a pre-phylloxera vine. Conversely, a vine planted in 1989 on its own roots in a phylloxera-free sandy soil, as Cappellano did with Otin Fiorin, is technically own-rooted but not pre-phylloxera by date. The distinction matters for exam accuracy: pre-phylloxera refers specifically to vines that survived the epidemic or were planted before it on their own Vitis vinifera roots, not simply to old or ungrafted vines.

• Vieilles vignes (French), vigne vecchie (Italian), and alte Reben (German) all mean old vines but do not confirm ungrafted status; wurzelecht (German) and piede franco (Italian) specifically indicate ungrafted own-rooted vines.
• No universal legal definition governs vieilles vignes or equivalent old vine terms; definitions vary by region, and many regions have none at all.
• Pre-phylloxera strictly refers to vines that predate or survived the phylloxera epidemic on their original Vitis vinifera roots, not simply to any ungrafted or old vine.
• Australia's Barossa Valley holds some of the world's oldest ungrafted vines, including Shiraz, Mourvedre, and Grenache dating from before phylloxera devastated Europe; Henschke's Hill of Grace Shiraz includes vines planted in 1868.
