En Vaso (also Gobelet or bush vine) is a traditional Mediterranean vine training method. Ideal for dry, hot climates. Learn more now!
En Vaso (Spanish for "in a glass" or "goblet-shaped"), also known as Gobelet (French) or Marco Real, is a traditional vine training method where vines grow as free-standing, low bushes -- without a trellis wire system or support structure. This ancient cultivation form is particularly widespread in the hot, dry regions of the Mediterranean and defines the landscape of many classic wine regions in Spain, southern France, and Greece.
In En Vaso training, the vine is shaped into a short, self-supporting trunk (30-60 cm tall) with several arms arranged in a circular or goblet-like pattern. The shoots grow freely upward and outward without being attached to wires. The result resembles a small bush or cup-shaped structure -- hence the names "En Vaso" (goblet) and "Gobelet" (cup).
The En Vaso method has proven itself over centuries in Mediterranean wine regions because it is perfectly adapted to extreme climatic conditions:
The extremely low planting density (often only 1,000-1,500 vines/ha in La Mancha) gives each vine a large root zone. In dry regions without irrigation, the vines can better utilize limited water resources without competing with each other.
The dense, bushy canopy protects the grapes from direct, intense sun exposure. The grapes hang sheltered inside the goblet, while the leaves on the outside act as a natural sunshade.
Despite the low growth height, the grapes benefit from ground proximity: at night, when the soil cools down, cool air sinks and moderates extreme temperatures. In regions with large day-night temperature swings (like the Spanish Meseta), this is valuable for acidity preservation.
The low, compact form makes the vines resistant to strong winds, which are common on many plateaus (like La Mancha or the Rhone).
In historical, remote, or extremely dry regions, wood for posts and wires was scarce and expensive. En Vaso requires practically no materials after planting.
Despite its perfect adaptation to hot, dry conditions, En Vaso training also has clear disadvantages that explain why modern vineyards are often converted to trellis systems:
All tasks -- hand harvesting, pruning, canopy management -- must be done by hand in a bent-over position. This is physically demanding and time-consuming.
Modern harvesting machines, leaf-trimming equipment, or mechanical picking devices cannot be used. This makes En Vaso economically less attractive.
The extremely low planting density means far fewer grapes are harvested per hectare compared to denser trellis systems. This is uneconomical for mass production.
The dense canopy makes it harder to monitor grape health and ripeness. Rot or disease can go undetected.
En Vaso training is typical of traditional wine regions with hot, dry climates:
In recent decades, there has been a trend to uproot old En Vaso vineyards and replace them with modern, mechanizable trellis systems. However, some quality-focused winemakers increasingly recognize the value of these old systems:
Today, old En Vaso parcels are increasingly valued and form the basis for premium wines that highlight this traditional training method on their labels.
| Criterion | En Vaso | Modern Trellis |
|---|---|---|
| Planting density | 1,000-2,500/ha | 4,000-10,000/ha |
| Mechanization | Not possible | Fully mechanizable |
| Yield/ha | Low | Medium to high |
| Labor effort | Very high (manual) | Low (mechanical) |
| Water needs | Minimal | Often irrigation needed |
| Grape quality | Can be very high (old vines) | Variable, depending on yield |
| Drought adaptation | Excellent | Limited |
| Infrastructure costs | Minimal | Medium to high |
En Vaso is more than just a training method -- it is a testament to centuries of adaptation to Mediterranean extremes. Even though this method is uneconomical for modern mass production, many quality-conscious winemakers preserve their old En Vaso vineyards as living cultural heritage and a source of extraordinary, terroir-driven wines. In times of climate change, this water-saving, sustainable cultivation method could even experience a renaissance.
