Adult leaves are pentagonal, with five lobes and deep lateral sinuses.
Details on the Bunch and Berry
The Spergola bunch is generally conical in shape, sometimes winged, and is medium to small in size. The average bunch weight varies, with data indicating around 210g and 300g in different sources, suggesting some variability depending on cultivation conditions and agronomic practices. The berries are medium-sized, tending to be round or slightly oval in shape. The skin is yellow-green, firm but thin, and the pulp is described as soft, harmonious, and pleasant.

The lateral sinuses are deep, and the upper surface of the leaf blade is medium green or dark green, with marked blistering. The shoot tip is yellow-green, while the upper surface of the young leaf may show red streaks.
What are the Cultivation Needs of Spergola?
The Spergola grape variety prefers rich, deep soils with good sun exposure. Its vigor is medium, with a drooping or semi-erect growth habit. Production per vine is around 2.2 kg, with bud fertility between 1.1 and 1-2. The plant shows resistance to summer drought and winter cold, but can suffer from frost.
What is the Growth Habit and Vigor of the Vine?
The growth habit of Spergola’s foliage is often described as drooping or semi-erect. The plant’s vigor is generally medium, though some sources indicate high vigor. This variability could depend on pruning practices and soil conditions. Production per vine is estimated at around 2.2 kg or between 1.5-2.5 kg, with bud fertility ranging between 1.1 and 1-2.
What Soils and Exposures Does it Prefer?
The Spergola grape variety prefers rich, deep soils with good sun exposure, which helps improve its quality. It adapts to various soil types, including calcareous ones, but thrives in cool, fertile, and deep soils. Resistance to summer drought and winter cold is a positive characteristic, although it can suffer from winter frost. Irrigation can increase production, but at the expense of quality.
What are the Recommended Pruning and Training Practices?
Spergola is commonly trained on a cordon or pergola system, with pruning varying from 3-5 buds to long prunings with 10-12 buds per vine. The choice of training system and pruning must consider the plant’s vigor and the desired qualitative objective.
What are the Phenological Stages of the Spergola Grape Variety?
Spergola's budburst is late (third decade of April) or very late. Flowering occurs on average (first decade of June) or between late May and early June. Verasion is medium (second decade of August) or very late. Maturation is medium-early (second decade of September) or very late.
What is the Sensitivity of Spergola to Diseases and Adversities?
Spergola is moderately susceptible to major fungal diseases. It is sensitive to botrytis attacks in case of abundant autumn rains, as well as powdery mildew and downy mildew. It shows medium resistance to grey mold. Tolerance to phylloxera is variable, with some sources indicating it is susceptible.
What are the Characteristics of the Must and Wine Derived from Spergola?
Spergola must exhibits an acidity varying between 6.8%o and 7.0-10.0%o, with a sugar content between 20.5% and 17.0-20.0%.
