How a tasting is carried out

The process of wine tasting is a practice that combines technique, knowledge and sensitivity to evaluate the organoleptic characteristics of a wine. Through sight, smell and taste, the taster analyses aspects such as colour, aroma, texture and flavour, in order to understand their quality, state of conservation and possible pairings. Although it may seem like a simple act, tasting requires training and attention to detail, as each phase provides relevant information about the origin, production and evolution of the wine.

The wine tasting is structured in several stages. The first is the visual phase, which allows you to get the first impressions of the wine. To do this, the crown is held by the stem and its color, intensity and brightness are observed on a white background. The color can offer clues about the variety of the grape, the age of the wine, or its production process. In red wines, for example, purple tones indicate youth, while tile or brown shades reflect evolution. In the whites, the greenish colours are characteristic of young wines, and the golden colours are characteristic of older or barrel-fermented wines. In addition to color, clarity, which reveals the absence of impurities, and fluidity are evaluated, observing the tears or legs that form when shaking the glass, indicators of alcohol and glycerin content.

The second stage is the olfactory phase, which takes place in two stages: on the nose and after shaking the wine. In the first approach, the taster perceives the most volatile aromas. Subsequently, when shaking the glass, more aromatic compounds are released, intensifying perception. Aromas are classified into primary, secondary and tertiary. The primary ones come from the grape and can be floral, fruity or vegetable. The secondary ones are generated during fermentation and are usually reminiscent of dairy, yeast or bakery. Tertiary ones appear during aging and provide notes of wood, spices, nuts or even balsamic and animal aromas. Identifying and describing these nuances is essential to understanding the complexity and personality of wine.

The taste phase is the most complete, as it integrates the sensations perceived in the mouth. The taster takes a small sip and distributes it throughout the oral cavity to assess the balance between the four basic tastes: sweet, sour, salty, and bitter. In wines, sweetness comes from residual sugars; acidity, from the natural acids of the grape; and bitterness, from the tannins present especially in reds. The texture or body of the wine is also analyzed, related to the sensation of density and volume in the mouth. During this phase, it is important to pay attention to the retronasal, that is, to the aromas that are perceived when exhaling through the nose while the wine is in the mouth, which allows a more complete assessment of its bouquet.

After tasting, the aftertaste or finish of the wine is evaluated, which is the sensation that remains after swallowing or spitting. A quality wine usually leaves a long and pleasant memory, while a simpler one disappears quickly. The duration and quality of the aftertaste are decisive factors in the overall evaluation of the wine.

In addition to the three main phases, the tasting also involves a global judgment in which the perceptions obtained are integrated. Here it is determined whether the wine is balanced, harmonious and representative of its type or denomination.

There are different types of tasting depending on the objective. The technical tasting seeks to evaluate specific parameters and is usually carried out by oenologists or professionals. Comparative tasting allows several wines to be analysed simultaneously to appreciate their differences. There are also blind tastings, in which the identity of the wine is hidden to avoid prejudice, and hedonic tastings, aimed at the personal and subjective enjoyment of each participant.

As an example, this is the result of some tastings of Bodegas Montebaco wines:

Montebaco De Finca, concentrated red, bright cherry color. On the nose it is elegant, sophisticated and somewhat complex, with aromas of ripe fruit and berries, spicy notes, minerals and fine wood. On the palate it is broad and fruity, with lively and vibrant tannins. Very pleasant.

Parcela Cara Norte, wine with personality, cherry red and violet rim. On the nose it is intense, with aromas of fruit, black fruit and fresh fruit. On the palate it is dense, with well-integrated acidity, balanced with fruity aromas such as black fruit, blueberries, blackberries and sloes.

Montebaco Special Selection, a resounding wine that has a cherry red colour with a slightly garnet rim. On the nose it has great complexity, with intense aromas. Fruity hints of black plums and blackberries, with lactic touches. It evokes exceptional ageing in a careful wood with spicy and dark chocolate echoes along with a delicate balsamic reminiscence. On the palate it is powerful, balanced and with a magnificent flavour. Enjoy ripe and silky tannins of exceptional quality.

Semele, a friendly and direct red wine, perfect for those who are starting out in reds aged from Ribera del Duero. On the nose it gives a perfume of blackberries and blueberries, adorned with floral notes and a spicy touch that gives it personality. On the palate it is tasty and fresh, with soft tannins that cover the palate without imposing itself.

Beyond its evaluative function, wine tasting is also a cultural and social tool. It allows you to discover the diversity of winemaking, understand the work of winegrowers and winemakers, and foster appreciation for a product with centuries of history. Each wine tells a story of its terroir, its climate and its production, and the tasting is the means to listen to it.

In short, wine tasting is a process that combines science, art and sensitivity. With practice and attention, anyone can develop their analytical skills and enjoy the nuances that each wine offers. It is not just about identifying flavors and aromas, but about living a sensory experience that connects with culture, gastronomy and the pleasure of sharing.

Organic wine has gone from being a curiosity in specialized stores to becoming a common choice among those who value sustainability, health and authenticity in the glass. But what is an organic wine really? What differentiates it from conventional wine? And why are more and more wineries opting for this way of understanding viticulture?

What is organic wine?

An organic wine is one made from grapes grown without pesticides, herbicides or chemical fertilizers. Organic farming methods are followed in its production, respecting the natural cycles of the vineyard, promoting biodiversity and avoiding aggressive artificial treatments.

To be certified as a certified organic wine, the winery must follow specific practices during winemaking. The use of sulphites is limited, non-permitted additives are excluded and processes that minimise environmental impact are committed. All of this is regulated by European regulations.

Benefits of organic wine. Choosing an organic wine is not just following a trend. It is a commitment to the planet, health and taste. Here are some of its advantages:

Respect for the environment. Sustainable wines are produced without polluting the soil or water. The absence of chemicals protects the auxiliary fauna and improves the health of the vineyard ecosystems.

Lower impact on health. As it does not contain pesticide residues or herbicides, organic wine is a cleaner and safer option. Ideal for those looking for a more natural and conscious consumption.

Best expression of terroir. Many experts agree, organic viticulture allows the grape to express more faithfully the character of the soil and climate. The resulting wines are more authentic, with defined aromatic profiles and no masking.

Support for the rural environment. Consuming organic wines from small wineries helps to keep the villages alive, generate local employment and preserve winemaking traditions that are part of the heritage.

Requirements to be an organic wine. For a wine to be considered organic, it must meet certain requirements throughout the process:

• Cultivation without chemical synthesis products
• Sustainable agricultural practices, such as groundcover and biological pest control.
• Organic winemaking, limited use of sulphites, native yeasts, minimal intervention.
• Official certification, with the European organic logo and the seal of the competent body.

This process of conversion to organic lasts at least three years. Only then can the wine be legally labeled as such.

At Bodegas Montebaco we make CaraNorte, an organic high-altitude wine. This wine comes from vines grown organically at an altitude of more than 800 metres. The vineyards are located between Valbuena and Pesquera de Duero. The north orientation, together with a cooler climate, allows a slow and complete ripening of the grapes, resulting in a very clean aromatic profile, with red fruit, floral notes and a mineral background.

Montebaco CaraNorte not only meets the requirements of a certified organic wine, it also represents a way of understanding wine as an expression of place and respect for nature. It is a clear example of how a quality organic wine can compete at the highest level, without compromising the origin or the future of the vineyard.

Spain is one of the leading countries in terms of organic vineyard area worldwide. Every year, more wineries join this form of production, driven by the demand of an increasingly informed and demanding consumer.

Spanish organic wine is the result of a work philosophy that seeks to protect the environment, take care of the consumer and make wines with soul. Initiatives such as that of Bodegas Montebaco with CaraNorte wine are an example that it is possible to look to the future of wine without losing the connection with the land.

In winemaking, there are elements that are protagonists from the first sip, the grape variety, the barrel aging, the terroir… But there are also silent, discreet processes that occur in the shadows of the tank or barrel and that, however, profoundly mark the quality and personality of a wine. One of them is working with lees.

The lees are the set of sediments that are formed at the end of alcoholic fermentation. They are mainly composed of dead yeasts (after having transformed the sugars in the must into alcohol), remains of plant cells, potassium bitartrate and other solid compounds.

They are differentiated between coarse lees, which are deposited quickly and are usually removed at the end of fermentation, and fine lees, which are lighter and remain suspended for longer. It is precisely these fine lees that are used in ageing on lees (élevage sur lies, in French), a technique that is highly valued in both white and sparkling wines, and more occasionally in some reds.

During aging on lees, a process known as autolysis takes place, in which dead yeasts slowly decompose, releasing compounds that enrich the wine. Among the most outstanding effects of this practice, we can point out:

• Greater volume and greasiness in the mouth

The polysaccharides and mannoproteins released during autolysis act as textural agents. They help the wine gain body, roundness and that enveloping sensation, which is often perceived as creaminess.

• Aromatic complexity

The lees give the wine notes that go beyond the primary fruit. Descriptors such as toasted bread, brioche, butter, nuts, yeast, and even certain spicy or lactic nuances appear, depending on the contact time and whether or not the batonnage (periodic removal of the lees) has been applied.

• Physicochemical stability

Mannoproteins also have a positive effect on the tartaric and protein stability of wine. In addition, they act as natural antioxidants, reducing the need for sulfites and allowing a slower and more harmonious evolution.

• Increased persistence

The aftertaste of a wine aged on lees tends to be longer and more structured, with a more solid sensation in the center of the mouth and a greater retronasal aromatic persistence.

Ageing on lees is a common practice in several styles of wine, especially in whites with a gastronomic or ageing vocation, where the combination of fermentation in barrels and ageing on lees results in elegant and deep wines. More and more producers are opting for ageing on lees.

An example would be Montebaco Rueda, made with grapes of the Verdejo and Sauvignon variety, aged for 3 months on lees, before bottling.

What role does batonnage play? Batonnage consists of periodically stirring the lees to keep them suspended inside the wine. This action promotes contact between the lees and the liquid, intensifying the release of beneficial compounds.

However, it depends on the style you are looking for. Excessive batonnage can overload the wine, make it heavy, or reduce its freshness. For this reason, many winemakers opt for static aging, where the lees rest without agitation, developing a more subtle and elegant profile.

Working with lees requires technique, sensitivity and patience. It is not just a matter of leaving the wine with its sediments, but of knowing when to intervene, how long to maintain contact and what style of wine you are looking to build.

When done well, the result is a more complex wine, with more nuances, texture and capacity for evolution. A wine that is not limited to liking, but generates conversation. That is not only drunk: it is analyzed, saved, remembered.

The passage of wine through oak barrels not only responds to practical reasons related to conservation and transport, as was the case in ancient times, it also has a profound impact on the aromatic, gustatory and structural profile of the wine. The oak barrel has established itself as an essential instrument in winemaking, transforming wine into a complex and refined drink.

The use of oak in winemaking is not new. For centuries, winegrowers all over Europe discovered that this wood was not only resistant and relatively easy to work with, but also had an amazingly positive impact on the taste and structure of the wine. There are two types of oak predominant in the world of wine, French and American. Each one brings different nuances.

French oak is finer in its grain and brings more subtle aromas, notes of spices, vanilla, nuts, even some smoke.

American oak, on the other hand, has a more open grain and usually delivers more intense hints of coconut, sweet vanilla and caramel.

The type of oak chosen, as well as the degree of toasting of the barrel, has a profound influence on the final profile of the wine.

But oak does not only provide aroma. Its real magic is in how it allows a slow micro-oxygenation of the wine. Through its natural pores, it lets in tiny amounts of oxygen that help soften tannins, stabilize color, and round out texture. He is a silent tuner, a master of balance.

Not all wines go through oak, and not all those that do need it. But in the case of wines with a vocation for ageing, or those that seek a deeper and more complex expression, oak becomes an indispensable ally.

And that’s the key, the good use of oak is not noticeable by excess, but by harmony. An overwood wine loses freshness and naturalness, a well-worked oak wine gains depth without losing its soul. At Bodegas Montebaco we are committed to high quality barrels, the result is a recognizable style, with structure, elegance and a modern touch that does not forget tradition.

Montebaco Cara Norte is aged in barrels for between 13 and 15 months, it is a wine with great clarity of aromas and very defined notes of fresh black fruit and hints of blue fruit.

Montebaco de Finca is also aged in barrels for 13-15 months, the result is a wine with remarkable evolution, defined character and impeccable elegance, which will reward those who have the patience to preserve it.

Montebaco Special Selection is a wine that is aged for between 14 and 18 months, a powerful but elegant wine, complex, with great character and good ageability.

Montebaco Semele is made with a 12-month barrel aging, it is a new red wine, which has roundness, freshness, aromatic richness and varietal expression.

Oak ageing is both art and science, there are crucial decisions that influence the final result, new or used barrel? Each election changes the course.

Even the size of the barrel counts. The traditional 225-litre (Bordeaux) are the most common, but there are wineries that use foudres or larger barrels, where the influence of oak is more subtle and the micro-oxygenation slower.

In addition, over time, the barrels also “get tired”, they stop providing aromatic compounds and become simple inert containers. That is why many wineries periodically renew their barrel stock to ensure that each aging has the right amount of wood.

But beyond the technical, oak also has an emotional component. There is something in that toasted perfume, in those notes of cocoa, coffee or leather that refers us to something deep, almost sensory. Oak-aged wine has soul, and it also has history. It speaks to us of time, of waiting, of transformation.

In a world that runs faster and faster, wine that passes through barrels is an invitation to stop. To savor slowly. To smell carefully. And to understand that the good needs its pause.

Oak, far from being a simple container, has become a transforming agent in winemaking. Its influence ranges from the sensory to the symbolic, representing the search for complexity, balance and harmonious aging. Used with criteria and respect, oak is able to enrich the wine without overshadowing it, giving rise to creations that combine nature, technique and tradition.

Behind each glass there is a fascinating process, fermentation, the moment when magic happens and the grape becomes wine.

The fermentation process begins in the vineyard. The quality of the wine depends on the grape, its ripeness and the terroir that sees it grow. In the vineyards of Bodegas Montebaco, located between Valbuena de Duero and Pesquera de Duero, altitude and extreme continental climate play a fundamental role in the balance of sugars and acidity.

Once harvested, the grapes are taken to the winery, where fermentation begins its chemical process, the yeasts, those invisible but essential microorganisms, get down to work.

Alcoholic fermentation is the heart of the process. The yeasts feed on the sugars present in the wort and transform them into alcohol and carbon dioxide, releasing heat along the way. Temperature plays a determining role, too much heat can kill the yeasts, and too much cold slows down the process.

Depending on the type of wine you want to obtain, fermentation takes place in stainless steel tanks, concrete or even oak barrels, each providing different nuances to the final result.

Once alcoholic fermentation is complete, it is the turn of malolactic fermentation, a process in which bacteria convert malic acid (more aggressive) into lactic acid (milder). This change reduces acidity and gives that silky and round sensation in the mouth.

Generally, this second fermentation occurs in oak barrels, which adds aromatic complexity and refinement to the whole.

The type of fermentation and the yeasts used influence the style of the wine. Young, fresh white wines are usually fermented at low temperatures with yeasts selected to preserve the varietal aromas. Red wines for aging, on the other hand, are usually fermented at higher temperatures with yeasts that provide complexity and structure.

After fermentation, the wine needs time to refine and evolve. The wines go through a meticulous aging process, where the oak provides nuances without overshadowing the fruit.

Time in barrel and bottle is essential for the tannins to soften and the aromas to integrate. Each wine has its own rhythm, and in the winery that natural cadence is respected so that when it reaches the glass, it expresses its full potential.

If the fermentation process teaches us anything, it is that wine is a balance between science and art. Controlling temperatures, choosing the exact moment for each intervention and knowing when to let nature take its course is what differentiates a common wine from an exceptional one.

Bodegas Montebaco has made this process its hallmark, combining tradition with innovation, respecting the character of the terroir and letting time do its work.

Scientific research and technological innovation continue to unlock the secrets of fermentation. New yeast strains, winemaking techniques and analysis tools allow winemakers to explore new frontiers and create increasingly complex and expressive wines.

Wine fermentation, an ancient and constantly evolving process, is an art and a science that requires knowledge, passion and dedication. Each wine is the result of a unique fermentation, a reflection of the terroir, the grape variety and the winemaker’s vision.

The next time you uncork a bottle, take a moment to think about everything that happened before that wine made it into your glass. Fermentation is the soul of wine, the process that transforms it, defines it and gives it life.
