PRESENTATION OF THE SAUVIGNON GRAPE VARIETY



Sauvignon is a variety of white grapes of French origin, cultivated for several centuries in the Loire Valley and Bordeaux region.

Today, Sauvignon is highly internationalized (123,000 ha in 2015), being present in all the major wine producing countries.

In New Zealand, it is the most cultivated grape variety with nearly 20 500 ha.

Sauvignon owes its success in particular to its varietal aromas of the thiol family (blackcurrants, exotic fruits, boxwood...) which express themselves differently

according to the soils, the vintages and the growing conditions.

It is for its particular aromas that it is often vinified into dry white wines then consumed young.

Sauvignon also produces high quality sweet wines.

Geo-economic distribution of Sauvignon Blanc throughout the world

In 2017, Sauvignon ranked 8th among the main vine varieties planted in the world with 123,000 hectares.

This variety is growing strongly, over +3%.

One third of the surface areas are in France and half in Europe.

More than 30 countries cultivate Sauvignon Blanc, 16 of which cultivate more than 200 hectares.

SAUVIGNON GRIS…



SAUVIGNON GRIS…

It is native to Bordeaux for some, endemic to Poitou for others.

It results from the grey mutation of Sauvignon Blanc with a slightly pink colour at maturity. It gives powerful wines with floral and muscat aromas.

It is also called Sauternes or Blanc Fumé in Nièvre, Ahumat in Béarn, Fié in Touraine or Surin in Poitou.

It was very present in the Loire Valley before disappearing completely because in 1958, there were only 10 hectares in France.

The area planted in France, although still confidential with 660 hectares simply doubled between 2008 and 2011, thanks to the work of enthusiasts, including

Jacky Preys in Valençay.

SAUVIGNON RESEARCH IN THE LOIRE VALLEY


Les expressions du sauvignon en Val de Loire

Sauvignon is a grape variety recognisable by its varietal aromas.

The main descriptors used to describe the odour of a Sauvignon correspond to a complex chemical reality that is the subject of numerous research.



Varietal aromas may be present in the fruit:

- either in an odorous state:

like pyrazines with the well-known green pepper smell in Cabernet grapes

or as terpene or norisoprenoid compounds found in Muscat varieties

- or in the form of non-odorous flavour precursors which will be revealed during the production of the wine:

like varietal thiols



If "pyrazines" and "terpenes" can be found in sauvignons, "varietal thiols" are the object of all attention.

The final quantity of the odorous compounds responsible for the varietal aroma of Sauvignon is very variable according to the terroirs, the cultivation practices

but also the vinification processes which will make it possible to reveal them.



The main varietal thiols (volatile sulfur compounds) are :

4MMP (4-mercaptopentan-2-one) giving smells of boxwood and broom...

A3MH (acétate de 3-mercaptohexyle) giving smells of boxwood, grapefruit zest, passion fruit, tropical fruit...

3MH (3-mercaptohexan-1-ol) giving smells of grapefruit, other citrus fruits, exotic fruits...



Beyond the chemical complexity, the difficulty is to "model" what is the part of the odour in intensity and quality coming from these main varietal thiols for

each taster according to the concentrations in the wines.

In collaboration with Pascal POUPAULT of the Institut Français de la Vigne et du Vin in Amboise, we worked on this subject in application of a research he was

conducting on sulphur compounds and sensory quality of Sauvignon wines.



SULPHUR COMPOUNDS AND SENSORY QUALITY OF SAUVIGNON WINES: REASONING THE SULPHITING AND PROTECTION OF MOULT

« The aromatic expression of Sauvignon wines is linked to the nature and quantity of sulphur compounds present and preserved. The aromatic profile takes shape at

harvest.

It seems that the protection of the juices before the fermentation phase is essential. The nature and the level of this protection decide the proportion of the three aromatic components (vegetal, varietal, reduction) and the profile of the wine until it is bottled. The difficulty of the developer consists in revealing the

varietal potential without favouring reduction. »

SULPHUR COMPOUNDS AND SENSORY QUALITY OF SAUVIGNON WINES: REASONING THE SULPHITING AND PROTECTION OF MUSTS

RESULTS - CONCLUSIONS - PERSPECTIVES

« Protection (inerting and moderate sulphiting) before the fermentation phase conditions the quantity and quality of sulphur compounds. If protection during pressing leads to the wines richest in thiols, overprotection leads to reduction.

Until the conditioning, the control of the reduction, by the management of the balance of oxidation-reduction, can be managed by a reasoned sulphiting.

By following such a route, the producer must be able to exploit and preserve the aromatic potential of his harvest to the fullest. »




DIFFERENT TYPES OF SAUVIGNON IN THE LOIRE VALLEY



From different raw materials, the professionals of the Loire Valley create very great sauvignons with

chosen profiles.

INTREPIDE 2017 Grape variety : Sauvignon – Touraine AOP

Technical itinerary :

- Parcel selection in the commune of Couddes because every year I find there grapes with the typical aromatic markers desired for this cuvée.

- Harvest very early (3am) to keep the thiols fresh.

- Direct pressing with splitting of the presses that are not reincorporated.

- FA at 17°C and racking early enough at the end FA to lighten the wine.

- Controlled yeasting, fining with pea flour.




INTREPIDE 2017

Grape variety : Sauvignon – Touraine AOP

« The intrepid cuvée will surprise you with its aromatic expression typical of a Touraine sauvignon and its freshness. The maturity index allows the selection of grapes at the ideal time when grapefruit and rhubarb aromas are present. A

traditional vinification will allow the wine to offer its most beautiful expression. »

Sauvignon Touraine AOP




CHÂTEAU DE PONT 2015 Grape variety : Sauvignon – Touraine AOP

Technical itinerary :

- Grapes grown to maximum maturity before stall and before the next rain! harvest in dry weather.

- Classic pressing with fractionation of the presses which are treated in hyperoxygenation with addition of glutathione and which are reincorporated.

- FA at 17°C, no FML.

- Classic ageing on fine lees for 15 months with light stirring.




CHÂTEAU DE PONT 2015

Grape variety : Sauvignon – Touraine AOP

« The Château de Pont cuvée is the fruit of an exceptional parcel located in the Indre et Loire region around Loches. Located near the Château de Pont and

over 25 years old, it offers grapes of rare quality, pushed to extreme maturity the aromas are concentrated with a beautiful finesse. Long ageing on fine lees

to perfect the naturally present aromatic potential. »
