When we think of the harvest, the image is usually immediate, ripe bunches, scissors in the hands, boxes filling with grapes and an intense movement in the vineyards and in the winery. However, the harvest does not begin on the day the first grape is cut.

In Ribera del Duero, that moment is only the visible result of work that has been going on for many months. Before the first bunch leaves the vine, the vineyard has come a long way and winegrowers and technicians have made numerous decisions. Because harvesting means deciding when a whole year of work has reached its peak.

Winter leaves the vineyard at rest. The vines seem to stop their activity and the landscape of the Ribera del Duero takes on a calm, almost immobile appearance. But under this apparent calm, a new cycle begins to be prepared and the soil and the plant continue to be worked: winter pruning, cleaning and removal of vine shoots, tying and driving, fertilising, revision of the structure…

With the arrival of spring, the vineyard wakes up. The first shoots appear and a period begins in which each weather change can influence the evolution of the plant. Temperatures, rain, wind or a late frost are part of a scenario that no one can completely control. It is time for green pruning, pest prevention and frost protection work.

Then summer arrives and the vineyard enters a new phase. The bunches evolve little by little and the grapes begin to concentrate everything that, months later, will be part of the wine. It is the time for defoliation and thinning of bunches.

But even at this moment we cannot yet speak of a harvest. Perhaps the most delicate part remains, which is to observe and wait, since, in the last weeks, as the end of summer approaches, the vineyard begins to be observed with even greater attention. The grapes change almost imperceptibly from one day to the next, but these small variations can prove decisive. The bunches continue to evolve, the aromas develop and the composition of the grapes changes progressively. At this stage, the goal is to find a balance.

Waiting can allow the grapes to continue to evolve. But waiting too long can also change that balance. Harvesting earlier can preserve certain characteristics, although ripening may not yet have reached the desired point. During these weeks, the vineyard becomes a place of constant observation. The bunches are checked. Plots are compared. The evolution of the grapes is analysed. The state of the skins and seeds is observed. And, at the same time, the sky is looked at. A forecast of rain, several consecutive days of high temperatures or a sudden change in weather conditions can force us to rethink decisions. The harvest is prepared, of course, but it also requires the ability to adapt. For this reason, in the days leading up to the harvest, the weather forecast becomes another tool in the work in the vineyard.

The decision to harvest rarely depends on a single signal. It is the result of many observations, accumulated experience, knowledge of each plot and the ability to interpret what is happening at that precise moment.

In Ribera del Duero, moreover, the continental nature of the climate turns each vintage into a different story. The conditions of one year are never exactly the same as those of the previous one. A warmer summer, a particularly rainy spring or a period of milder temperatures in the last weeks can modify the rhythm of the vineyard.

A harvest is never simply a repeat of the previous one. Every year it forces us to look again, to compare again and to decide again. Not all the grapes arrive at the same time, within the same estate there may be differences between plots. The orientation, the type of soil, the age of the vines or the particular conditions of each area influence the rate of ripening.

This means that the question is not always only “when does the harvest start?”, on many occasions, the question is, where do we start?

Deciding which plot to harvest first is part of that invisible work that happens before the first grape is cut. The organization must allow each plot to be harvested at the time when it is considered most suitable and, at the same time, coordinate the arrival of the grapes at the winery.

That first bunch that leaves the vine does not only represent the beginning of the harvest. It represents a full year of work in the vineyard. Months of decisions, care and observation that culminate in an apparently simple moment: a pair of scissors, a bunch and the first grape that begins its way to the winery.

And behind the first grape there is a whole story that, months later, will be told again in a different way, in a glass of one of the excellent wines of Bodegas Montebaco.

The biological cycle of the vine is a succession of small daily miracles, but none has the oenological significance of veraison. This period, which usually occurs throughout the month of August, marks the exact moment when the vineyard leaves its vegetative phase of green growth to devote itself completely to the ripening of the fruit. In the Ribera del Duero Designation of Origin, characterised by a harsh continental climate and remarkable altitudes, veraison is not only a chromatic change in the landscape, but the true turning point that will determine the aromatic profile, structure and elegance of the final wine.

In this scenario, Bodegas Montebaco stands out, a unique winemaking project whose Monte Alto Estate – nestled between the Valladolid municipalities of Valbuena de Duero and Pesquera de Duero – acts as a privileged witness to this transformation. To understand the importance of veraison in the Ribera del Duero and, more specifically, in the high-altitude vineyards of Montebaco, is to look into the secret of its wines.

From a botanical point of view, veraison is the time when grape berries stop their cell division and begin their organic ripening process. Chlorophyll, responsible for the characteristic spring green of the bunches, begins to degrade progressively. The red varieties synthesize anthocyanins, the polyphenolic pigments responsible for dressing the grape skins with spectacular purple, bluish and violet tones.

During the weeks that elapse from the beginning of veraison to the harvest, the grapes undergo decisive biochemical transformations:

Sugar input, the berry drastically increases the accumulation of glucose and fructose from foliar photosynthesis.

Loss of acidity, the concentration of organic acids (mainly malic and tartaric acid) begins to drop gradually.

Softening the pulp, the cell wall of the berry becomes flexible, increasing the elasticity of the soot.

Synthesis of aromas and phenolic compounds, this is the critical period where the fruity aromatic precursors accumulate and the tannins condense, vital for the volume and aging of the wine in barrels.

In the Ribera del Duero, this process takes place in the midst of the summer rigors. The high daytime temperatures of August accelerate photosynthesis, but the altitude and the continentality of the climate impose a rapid thermal drop at nightfall. This enormous thermal amplitude is the key for veraison to trigger a slow and balanced ripening.

To understand the real impact of veraison at Bodegas Montebaco, it is essential to situate your vineyard. The property forms a real “island” within the Ribera del Duero: a valley of its own furrowed by the Jaramiel stream that rises between 840 and 900 meters above sea level.

This height level places Montebaco at the upper limit of cultivation in the region. When veraison arrives, the altitude of the Monte Alto Farm intensifies the positive effects of the microclimate and the characteristics of the Estate: extreme thermal amplitude, calcareous and clayey soils, sun exposure and ventilation.

The slow pace of ripening that begins with veraison allows the development of a rich palette of primary aromas, notes of fresh black fruit (blackberry, blueberry, wild plum), small floral nuances and mineral touches typical of the limestone of the land, which are then respectfully integrated with oak aging.

Ultimately, veraison in the Ribera del Duero represents the moment when nature dictates the personality of the vintage. At Bodegas Montebaco, a careful reading of this phenomenon in the 53 hectares of the Monte Alto Estate translates into precision viticulture: adjusting the leaf removal, monitoring the load per vine and determining the right harvest date plot by plot.

The result is wines that faithfully capture the personality of the terroir, the strength and concentration of the Castilian land, tempered by the finesse, freshness and minerality provided by the altitude. Each bottle of Montebaco keeps inside the silent echo of those August afternoons when the Valbuena vineyard changed color to transform the sun into pure liquid poetry.

Winter is a time of pause, silence and apparent stillness, but under the surface there are decisive processes that will mark the character of the next harvest. Understanding what happens in the vineyard during these cold months helps us to better understand the wine that will then reach the glass.

With the arrival of the cold and the decrease in daylight hours, the vine enters what is known as vegetative stoppage. It is their natural way of protecting themselves against low temperatures and conserving energy. During this phase:

• The sap descends to the roots.
• The plant’s metabolic activity slows down to a minimum.
• The vine stops growing and concentrates on staying alive and strong.

This rest is essential to restart the cycle with balance in spring. In a way, winter is to the vine what deep sleep is to people, a vital necessity.

Although on the surface the vineyard seems completely asleep, the work continues under the ground. The roots are still active, especially in well-drained soil, exploring the terrain and storing reserves.

These reserves (starches and nutrients) will be essential when sprouting arrives. A vine that has spent a balanced winter will have more strength to start the cycle and develop quality clusters.

For this reason, the structure of the soil, its aeration and its drainage capacity are especially important during these months. In which the winter cold is a great ally of the vineyard:

• It helps to eliminate pests and diseases that could affect the vine in spring.
• Promotes a deep and homogeneous rest of the plant.
• It contributes to a more regular budding when temperatures rise.

In areas such as Ribera del Duero, where winters are cold and marked, this factor is key to maintaining the health of the vineyard and the quality of the grapes. The balance between cold, humidity and rest is one of the bases of the character of the wines of the area.

If there is a leading job in the vineyard during the winter, it is pruning. Far from being a mechanical task, it is one of the most important decisions of the year. Pruning means choosing:

• How many shoots will the vine have in spring.
• How the production will be distributed.
• What a balance there will be between vigor and quality.

At Bodegas Montebaco, pruning is carried out with a clear vision, respecting the plant, its age and its adaptation to the terrain. A well-executed pruning allows yields to be limited, to promote homogeneous ripening and, ultimately, to obtain grapes that faithfully express the vineyard from which they come.

Winter is never the same from one year to the next, and the vineyard responds to every climatic variation. Intense frosts can be beneficial if they remain within the usual values, but they also pose a risk if they are extreme or prolonged. Winter rains help to recharge the soils with water, which is essential for the dry summer months. Snow, although rare in some years, acts as a natural insulator, protecting the soil and gradually providing moisture.

The key is balance. A winter that is too mild can bring budding earlier and increase the risk of spring frosts, while an excessively harsh winter can cause stress on the plant.

Everything that happens in winter leaves its mark on the next harvest. A well-rested vine, properly pruned and adapted to the climatic conditions of the year will be able to offer grapes with greater concentration, balance and personality.

That silent work is what, months later, translates into wines with identity, such as those of Bodegas Montebaco, where the vineyard is always the starting point. Every plot, every orientation and every soil begins to define the wine long before the first green shoot appears.

Although the consumer does not always perceive it, winter is present in every bottle. In the structure of a red wine, in the freshness of a white or in the elegance of a wine that evolves over time.

When you enjoy a wine, you are also savouring the cold of January, the pruning decisions and the patience of a vineyard that knew how to wait for its moment.

At Bodegas Montebaco, we understand winter as a time of respect and observation, where every gesture counts. Because before the wine reaches the glass, there was a vineyard that knew how to listen to winter.
