Key people in winemaking in Spain

I would like to review the contributions to the improvement of wine quality in Spain. There are many winemakers and oenologist, and luckily their number is increasing, who focus on quality and contribute their knowledge and know-how to winemaking. I would simply like to remember three of these great contributors, who I deeply admire and who were key figures in the 80s and 90s.

In the 80s, on a visit to Rueda and Ribera del Duero, I was offered some Pesquera wine that was fantastic. Back then that wine was not well-known yet. How balanced and structured! Mature, with elegant tannins, deep, long. I was pleasantly surprised by it since that was what we were looking for in El Priorat: making wines from mature grapes.
When I had a chance to visit Pesquera, I jumped at it. Alejandro Fernández showed me his vineyard and told me about his new projects, a new vineyard he was working on at a height of more than 1000m. During the course of the conversation, I had the sixty-four-thousand-dollar question in my head so I finally asked “Listen Alejandro, what criteria do you use to know when to harvest?” “Why, I do what my father did, I harvest after La Pilarica!”(a festival celebrated in honour of the patron saint of Zaragoza, on 12th October) replied Alejandro. His answer confirmed the stage of maturity of the grapes expressed in his wine.
On a different occasion, in conversation with some oenologists, the subject of Alejandro’s harvest came up. Some of them said (with a kind of giggle …): “Alejandro gets to the vineyard, takes a few grapes at random, crushes them, rubs his hands with the juice, and, depending on what he sees, he decides to continue harvesting there or he may change to a different plot of land.” The oenologists said Alejandro trusted more his sense of touch than any analytical monitoring. To me that was quite shocking because this is in fact a very rigorous way of getting the same information as with an analysis of phenolic maturity; if your hands are stained red with the juice and are sticky, that surely means that the hypodermic cells have started lysis and the level of sugar is sufficient to start harvesting. Alejandro’s father’s observations were quite extraordinary and represented the conclusions drawn at that time.

Another important figure in the decade of the 80s is Fernando Remírez de Ganuza. With his dedication to achieving quality, he found the different concentration levels (of tannins, colour, aroma, polyphenols …) in the upper and lower part of the same tempranillo grape bunch. So, in order to make the most of this, he cuts each bunch in two so that the upper part is used in the elaboration of reserva wine and the lower part in the elaboration of young wine.
He has also devised a system of static press that works by placing a water bag on orujo that has been previously drained; the bag is left on the orujo for a while so that the weight of the bag itself acts as a static press without any type of energy consumption. With just some gentle pressure and longer time, he manages to get the best of draining.
I think that actions like these showed rebel and subconscious nonconformity when they decided not to abandon their land. They were committed to economic and intellectual effort, creating wines that, in time, have achieved to be among the best.

I do not know if Mariano García has invented anything but I do know that, with his experience, knowledge, and deep sensitivity, he has contributed enormously to improving wine quality. When he comes across a vineyard that can produce quality grapes, he does not care about denominations of origin. He shows that he knows the vineyard and its environment and knows how to work in the vineyard in order to get great wines: tasty, robust, and elegant. Wines that we enjoy drinking. This is Mariano García’s distinctive imprint.
He is probably the most well-known and respected oenologist in Spain. He is able to transmit a strong desire for self-improvement to those of us who are in the field of winemaking.

I would just like to thank them for their contributions. All the best for you three!

In art, lineages don’t mean much

The French revolution overthrew monarchy in France but it is quite surprising to see that, after all, some subconscious remnants still persist in some aspects. This can be observed in, for example, their strong defence of “terroir”. The quality of their great wines is attributed to the soil and climate, which have obviously prevailed for ever and ever like a reigning dynasty. Moreover, in some cases, the soil is believed to be a kind of “sacred gift”, where quality is a consequence of the monks’ work, since they are the representation of heaven on earth.

I am convinced that things will go on like this for as long as the current generations last, since great wines will go the same way as cuisine, I mean, until not long ago haute cuisine could be found in famous restaurants but, what happens nowadays? We are no longer interested in going to a classic, renowned restaurant. We now look for a given cook, the authentic artist, the one who incessantly tries to find balance and harmony in his/her dishes, apart from an explosion of aromas and a wide variety of textures, always taking into account the quality of the produce. Nowadays we are much more demanding than we were in the past and this is due to social evolution. We evolve all together and although we sometimes believe that the old days were better, food and wine included, we are wrong.

It is interesting to see how man is anchored to this world, even though he meets his individual, personal death. It is absurd to ascribe the exclusivity of particularity to the environment. ART is an asset to the individual, to singularity. Collectiveness leads to tendencies but it can never substitute it. Being a descendant of an art genius does not imply that you are an artist. The way of working can be passed down but one’s creative spirit is unique, on one’s own inside; you either have it or you don’t.

I think it is important to clarify that the environment, terroir (soil and climate), has a direct influence on wine “typology”. This breaks new ground for those of us with an artistic vocation for the making of new wines. But in any “great” wine there is a bonus for excellence that does not belong to any “lineage”; it belongs to the artist that has created it. These are things that we all have to earn, lineage or monarchy mean nothing in this regard.

The key is grapevine vigour distribution

January 9th, 2012 by Josep Lluis Perez

The studies done in the last years have helped us to understand what actions need to be carried out in grapevine growing so that the shoots are not too big. The base of this principle is VIGOUR DISTRIBUTION.

- Grapevine vigour can be defined, in a simplified way, as the weight of wood (shoots) produced during the vegetative cycle.

- Grapevine productive capacity or vigour is more or less constant if the external parameters it is defined by do not change over time. But the number of shoots left after pruning can vary depending on the adopted criteria.

- Vigour, i.e. the capacity to produce wood, is distributed or “used” as the shoots grow. That is to say, if the weight of all the shoots on a vine is the expression of its vigour, when more or less shoots are retained, we are in fact distributing vine vigour. If many shoots are left, they will grow a little. If a few shoots are left, they will grow a lot.

For example, in a vine of whose vigour is 500: “The weight of all its shoots is 500 grams”

- If, after pruning, 10 shoots are left (500/10), each shoot will weigh 50gr and will measure approximately 1.20m in length. The diameter will be more or less 8 – 10mm.
- If, after pruning, 5 shoots are left (500/5), each shoot will weigh 100gr and will measure more than 2m in length. The diameter will be larger.
- If, after pruning, 20 shoots are left (500/20), each shoot will weigh 25gr, will measure approximately 0.60m in length, and will have a small diameter.

Length has been checked by measuring and weighing shoots of different dimensions and varieties. You can check how we did that in this article.

In short, what we want is to have shoots of 8-10mm in diameter and approximately 1.20m in length at the most in order not to remove shoot tips. In other words, we want to get shoots that weigh approximately 50gr.

Conclusion: Vigour is distributed dividing the weight of the wood cut by 50gr. This will give us the number of shoots that can be retained so that they can show good morphological characteristics and produce quality grapes.

Wine in the World

January 2nd, 2012 by Josep Lluis Perez

In the 80s there was a plethora of nonconformist ideas coming from all the wine-growing regions in the country. We had come from a decade when the demand for bulk wine had reduced. Spain, which back then was the country with the highest production of this type of wine, was hit by a sale crisis and wine surplus rose.

The cause was mainly the use of technology in northern European countries. In those countries sugar was added to increase the wine colour and as a result of this, they did not need to import so much wine from southern Europe.

The reaction to this was collective all over Spain. The so-called “improver” wine varieties such as Chardonnay, Merlot, Cabernet, etc, started to be planted and regrafted. All over the place new wineries were set up by people who did not belong to any winemaking family saga but to other professional fields and were not willing to let their homeland to lose economic power. That was an extraordinary moment! Together with some of the former students at the vocational school in Falset, we planted French grafted vines in the regions of Rueda, Ribera del Duero and some others. In those parts of Castile big plots of land, where beetroots had previously been grown, were now planted with vines.

That was the time when the well-known critic, Mr Robert Parker, wrote that he had found the “Spanish Petrus” in reference to Mr Alejandro Fernández’ Pesquera wine. That provided a morale boost for all those people who, like ourselves, had their hopes pinned on their own incipient projects. Mr Parker has been frequently criticised but I believe that the idea he wanted to express is that quality wines can be made wherever man likes (within limits, of course) and that great wines do not belong only to classic European wine-producing regions, as it was believed then.

Italia 1985

We would, nevertheless, like to draw attention to the importance that these regions, like Bordeaux or Burgundy, have had in the development of quality wines all over the world. Back then, we paid constant visits to all the European wine-growing regions. The students in the vocational school, as it is mentioned in the previous article, with their way of acting and that moment in our lives also left their positive imprint on each of us.

Vigorous vines cannot produce quality grapes?

December 27th, 2011 by Josep Lluis Perez

  • català

This is a widely-spread topic but in Mas Martinet we have been working hard on this concept that has always been of concern to me. For quite a long time now we have been studying how we can help vigorous vines to produce high-quality grapes.

1. We know that the environment affects their genetic code, adapting their physiology to the changing weather and soil factors.

It is obvious that the vine will grow better in a fertile than a poor soil and its fruit will grow more but will be less tasty, with less content.

1st conclusion: In different types of soil fertility, different types of grapes are produced.

2. We know that grape morphology is a determining factor that influences the level of wine quality. That is to say:

- Grape clusters that are not compact, with loose berries, have a homogeneous maturation as a whole. This is a really important condition to get quality wines.
- Compact grape clusters, with tightly packed berries, have a very heterogeneous maturation. The berries in the outer part of the cluster ripen earlier than those in the inner part. With this type of grapes it is quite difficult to make excellent wines.

2nd conclusion: Grape morphology affects wine quality.

Taking this deduction as a starting point, how can we make vines to produce grape clusters with loose berries?

3. We have observed that those shoots that have a small diameter, as a general rule, produce small clusters with loose berries.

We did a statistical study that tried to establish a relationship between shoot diameter and grape morphology and we found that:

3rd conclusion:
- Those shoots with a diameter between 7 and 10mm produce, in a high percentage, clusters with loose, medium and small-sized berries.
- Those shoots with a larger diameter mostly produce big, compact clusters.

Taking this into account we should manage to get shoots with a diameter no bigger than 10mm.

How can we get this? I will explain this later on.

Our arrival

In 1981 and after a long time working as a teacher of natural sciences and biology at Viaró School in Sant Cugat del Vallès, Montse and I decided to move to the rural area of El Priorat and work in a vocational school in Falset. I had the feeling a stage of my life was over. A stage where I had learnt how to teach and enjoyed myself very much doing this for the eight years I worked there. But I wanted to go back to my rural origins, I had the urge to experience and share the problems and the day-to-day country living, and, why not, participate in making the future of the young winemakers a bit better.

When we moved there, unlike most of the people that nowadays come to El Priorat from all over the world, we had no intention of working in the field of winemaking or viticulture. Montse, also a graduated biologist like myself, got a post as a science teacher and I was the responsible for the technical management of the school and also taught. We shared this adventure with our children Sara, Núria, and Adrià. Jordi was born three years later.

El Priorat, an inland and harsh region but with a strong personality, did not offer many prospects back then, at the beginning of the 80s, and the majority of young people left their villages at the slightest chance. The area needed a plan for the future and, like with any good plan for the future, this involved the fields of education and training. And the plan was finally implemented. In 1982, Mr Jaume Ciurana i Galcerán, director of INCAVI (Catalan Institute of the Vine and Wine) proposed us to open a new specialty in the school: Viticulture and Oenology, a three-year course program. This was a specialty that had been very recently created and the school in Falset was one of the first schools in Spain offering the program. You can check the photo gallery of the beginning of the school.

Since we did not know anything about that field, we employed outside teachers so that we could start the new project.

In 1983, a new facility is built next to the main school building where the specialties connected with the winery, laboratory, ageing and tasting will be taught. We devote most of our time to studying, experimenting, and , together with the students, making wine with the grapes harvested in the school’s property but also buying grapes to neighbouring wine makers. This wine was sold to the school’s students and half the benefits were spent on new laboratory material to do experiments and the other half went on the end-of-year trip.

On these trips we visited wineries and vineyards in the main European wine growing regions. Every year we went to a different region: Bordeaux, Burgundy, Piamonte, Champagne, Alsace, Rheingau, Valais, etc. Back then there were no low-cost trips or low-cost accommodation like now, and even the Internet was not available, that meant we had to do all we could so that the trips were as cheap as possible. We travelled by bus, we had our tents and put them up in camp sites where we spent the night. There was a cook in the group, Rafel, who cook us dinner every day after our visits. We had a wonderful time and, what’s most important, those were extremely profitable experiences for the students.

Promoció 86/87

I would like to stress the methodology we used. Most of the academic topics became experimental and illustrative. We designed “experiences” that the students had to do and the most significant were selected to take part in the CIRIT competition organised by Generalitat de Catalunya, which was devoted to research carried out at schools. We won on different occasions and the money awarded also went on the organisation of those trips.

I love teaching and those were wonderful years that I really enjoyed. For me it was a privilege to have been able to somehow contribute in the education of those young people who were so willing to learn. Their parents were mostly wine makers in the region who were quite disappointed with the terrible situation of wine making at the time and they were undergoing a metamorphosis that gradually led them to wish to work the old vineyards of the family, make their own wine and change and revive El Priorat.

Shoot anatomy

After the 2007 harvest we did a study to know the physical characteristics of the shoots of our grapevines so as to better understand plant balance when deciding the type of pruning and grape thinning.

From the varieties of Grenache, Cabernet, Merlot, and Syrah, we chose 96 shoots of different lengths at random and the following data was analysed:
- Number of leaves
- Foliar surface
- Shoot length
- Shoot weight
- Shoot diameter

Merlot

When comparing all these varieties, we could see that the Grenache shoot is the heaviest, the thickest, and the one with the highest foliar surface per shoot length. On the other hand, the Syrah variety shows the lowest values in all these aspects. The Merlot shoots are less heavy than those of Cabernet although they produce a bigger foliar surface.

But we are interested in getting data we can refer to, so we measured the 120cm shoots, which is the ideal length for the type of trellis system we have, and we got the following data: length: 120cm; weight: 46gr; diameter: 8mm at the base; foliar surface: 0.25m2.

The parameters of this first study were the base for our future studies on vigour. Little by little we tried to understand grapevine behaviour and later on we did a very interesting study on these concepts.

Pruning: a corrective intervention

December 5th, 2011 by Josep Lluis Perez
  • castellano
  • català

Pruning is an aggressive action on the vine carried out by the viticulturalist repeatedly every winter. The stems are part of the arms or cordons, since they extend laterally from these fibrovascular bundles. When cutting a stem during pruning, the part that joins the stem to the arm gets dry. It is very important that the cut is not made at base level, it is better to leave the stem a bit long and keep a small part of it, so that the wooden part that gets dry is in the external part of the arm and does not grown inwards, this way, there will be no problems in the transportation of sap to active bundles.

In our vineyards, annually an average of 15 stems per vine are cut off; this means 15 injuries and 15 dry sections. If we extrapolate these 15 cuts in a year to the next 20 years, we will end up with 300 dry sections left by 300 stems cut along these 20 years.
These 300 dry sections are a big obstacle for the transport of sap (water and nutrients) along the xylem vessels to the cells that make up tissues, organs, that is to say, the plant itself.

If the vines are planted in fertile soil, the vigour of the soil will foster the growth of the tissues that can repair the damage and the vine will recover during the continuous vegetative cycles that will take place. But if the vine is planted in poor soil, the growth of the tissue able to repair the damage will be insufficient and the vines will gradually lose vigour and their production will be significantly reduced with time.

Therefore, pruning is one of the main causes of vine ageing. It is also one of the factors that cause vigour reduction and this will possibly be reflected in the wine personality.

Cep podat

We obviously do not intend to damage the vine with this aggressive action. Our aim is to get maximum production, top-quality grapes and the longest possible life for the vine. With this objective in mind, we will list some observations made along many years’ experience:

- In order to produce wines of quality and character, the grape clusters must be small and the berries loose. This is the ideal morphology for homogeneous maturation.

- The morphology of the berries depends on each individual variety and vigour.

- Stem diameter and length depend on the relationship between the number of stems and their vigour (in grams).

- According to some checks made, a 1.20metre-long stem weighs 50grams.

- When we come across a weak vine with short stems, that is a consequence of leaving too many stems in relation to the vigour the plant has.

- When we come across a vine with excessive vigour, the stems grow continuously, that is a consequence of leaving too few stems in relation to the amount of vigour the plant has.

We are then forced to redefine the concept of VIGOUR:

We use the term “vigour” to define the grapevine’s capacity to produce wood and grapes. In fertile soils, the vine has more capacity to produce (wood and grapes) and in poor soils, its capacity is reduced.

On the other hand, we can talk about an apparent type of vigour for those unbalanced vines whose growth does not stop during veraison, when the stems become wooden. If we never pruned, in nature we would not find some vines being more vigorous than others, we would find vines with different amounts of branches and foliar mass, because in nature there are different types of soils, some that are more fertile or poorer than others. Pruning must then, like any artificial intervention, help us to distribute or balance vigour in each plant.

We would now like to draw a conclusion on this point:

It is said that fertile soil produces grapevines with a lot of vigour and low-quality grapes. But experience shows that with corrective pruning, we can balance the vigour of each vine regardless of soil fertility. This is how we manage to make grape quality independent of soil quality.

Why I want to tell you about it

November 28th, 2011 by Josep Lluis Perez

Much has been said, and is still said, about the resurgence of El Priorat in the world’s winemaking panorama. Everybody seems to have something to say, either because they have heard a conversation, or read an article, or seen a documentary, or just because they have heard something … The guided visits offered in different wineries also play a part in this: there the same thing can be explained in different ways since it has really been experienced differently… No need to mention our personal interpretation. Of course, this means that you often hear claims and statements almost “ex cathedra” that have absolutely nothing to do with the original thing, with what really happened.

That is why I got the idea (taking advantage of this extraordinary means of communication!) of explaining “my personal experience” through all these years.  I do not intend to deny or reaffirm anything but I would like to show all the things we have been doing so far to those interested. Things do not tend to happen overnight; my thoughts and my way of doing things evolve gradually. Our aim is to make a good product in a specific place and the process has to be environmentally balanced, i.e. environmentally, socially and economically sustainable. But in order to reach this goal, as I said before, there has been an evolution. Some of the things I did 10 years ago, I would not do them now and probably some of those I do now, I will not do them in 10 years’ time.

We will then briefly go through “my” evolutive story in El Priorat, by uploading short articles in this blog.

Influence of the climate in the character of the wines

October 23rd, 2008 by Josep Lluis Perez
  • castellano
  • català

It is very important to take account of the climate in a given wine region because the different climatic variables take part in the development of the vine, in the genetic expression of the grape and consequently in the character of the wine.

From the four main climatic variables, which define the climate of a region, three cannot be altered by man: temperature, relative humidity, and solar radiation. But rainfall is the only one of these variables that can be modified.

In areas with low rainfall, the winemaker can supply water by means of irrigation and so control the plant and grape quality. But in the areas where rainfall sometimes exceeds the needs of the plant, the producer is unable to eliminate excess of water and that becomes a limiting factor for grape and wine quality.

Rainfall, which can be modified through irrigation, is highly important in the part of the Mediterranean where we are. Here rain mainly falls in some springs and most autumns. However, in the three summer months, it seldom rains. That is why for us it is highly important to know the amount and the moment when water has to be supplied to the vine in every stage of the vegetative cycle. Our studies have been orientated in this direction for years and now we continue in a more detailed way: we want to observe how rainfall in summer is distributed in different prestigious winegrowing regions taking good vintages into account.

We want to observe rain distribution in every stage of the vegetative cycle in Burgundy, Bordeaux, Piemonte and Mas Martinet (Priorat) but focusing on the rain falling from July to mid-October. We are also going to see the total amount of water that our vines get in summer not only from rain but also from irrigation.

We are going to explain in general terms how water acts on the plant (vine) and on the fruit (grape) in every stage of the vegetative cycle:
