Pure wine vs natural wine

Abstract

English version below

Vins purs VS vins natures.

S’il n’existe pas de réglementation officielle, la démarche des vins naturels prône un retour aux pratiques dites ancestrales préconisant notamment un mode d’élaboration des vins utilisant le moins d’intrants possible. Le seul autorisé reste l’anhydride sulfureux (SO2) à des doses quatre à cinq fois moins importantes que pour les vins dits conventionnels. Ce désir de renouer avec des pratiques anciennes et plus respectueuses des sols, du végétal et du produit vin trouverait-il un fondement historique ? 
Les textes et les ouvrages, notamment ceux des XVIIe et XVIIIe siècles, mentionnent des vins « bon, pur, loyal et marchand ». Qu’entend-on alors par un vin pur ? Pourrait-on trouver dans cette définition les prémices des vins naturels ? 
La littérature domestique et gastronomique étant très fournie sur cette période, la consultation d’auteurs tels que Nicolas de Bonnefons, Besnier, Angran de Rueneuve, Louis Liger d’Auxerre, Lemery et bien d’autres lève le voile sur les pratiques viticoles et vineuses d’une époque où cette notion de vin pur revient assez fréquemment. Élaboration, vinifications, élevage, conservation des vins, traitements, ces pratiques de l’époque moderne annoncent-elles la philosophie adoptée par les vins naturels d’aujourd’hui ?

Although there is no formal regulation, the natural wine approach calls for a return to ancestral practices, which include a wine making process using as few inputs as possible.
The only one authorized is sulphur dioxide (SO2) at doses four to five times lower than for conventional wine. 
Would this desire to reconnect with old practices , more respectful of soils, plants and wine has a historical basis?
Books, especially those of the 17th and 18th centuries, mention wines which must be “good, pure, loyal and merchant”. But what is the meaning of a pure wine at that time? Could this be considered as the firstfruit of natural wine?
As domestic and gastronomic literature is very abundant during this period, consulting authors such as Nicolas de Bonnefons, Besnier, Angran de Rueneuve, Louis Liger d’Auxerre, Lemery and many others could shed light on winemaking practices of a time when notion of pure wine comes up quite frequently. Wine making process, vinification, ageing, conservation of wines, treatments, do these practices announce the philosophy adopted by the today natural wine?

Water and physiological response to early leaf removal of cv. Verdejo in rainfed conditions, at different times of the day, in the D.O. Rueda (Spain)

Aim: Early leaf removal, generally applied before flowering, is mostly conceived as a technique to control grape yield and improve the health of grapes and focused on the final objective of increasing wine quality.

Impact of the pre-fermentative addition of enological adjuvants on the development of UTA in wines

During alcoholic fermentation and wine aging, indole-3-acetic acid (IAA) can degrade into 2-aminoacetophenone (AAP). The presence of reasonable amount of AAP in wines is regarded as the main cause of untypical ageing

‘TROPICAL’ POLYFUNCTIONAL THIOLS AND THEIR ROLE IN AUSTRALIAN RED WINES

Following anecdotal evidence of unwanted ‘tropical’ character in red wines resulting from vineyard interventions and a subsequent yeast trial observing higher ‘red fruit’ character correlated with higher thiol concentrations, the role of polyfunctional thiols in commercial Australian red wines was investigated.
First, trials into the known tropical thiol modulation technique of foliar applications of sulfur and urea were conducted in parallel on Chardonnay and Shiraz.1 The Chardonnay wines showed expected results with elevated concentrations of 3-sulfanylhexanol (3-SH) and 3-sulfanylhexyl acetate (3-SHA), whereas the Shiraz wines lacked 3-SHA. Furthermore, the Shiraz wines were described as ‘drain’ (known as ‘reductive’ aroma character) during sensory evaluation although they did not contain thiols traditionally associated with ‘reductive’ thiols (H2S, methanethiol etc.).

Characterizing chemical influences of smoke on wine via novel application of 13c-labelled smoke

Smoke impact is an ongoing and growing issue for vintners across the globe, with the west coast of the U.S. and Australia being two of the largest wine industries impacted. Wine has shown to be especially sensitive to smoke exposure, often acquiring off-flavor sensory characteristics, such as “burnt rubber”, “ashy”, or other medicinal off-flavors.1 While several studies have examined the chemical composition of smoke influences on wine, some studies disagree on what compounds are having the largest impact on smell and flavor.2 This study is designed as a bottom-up approach to inventory the chemical compounds derived from smoke from a grassland-like fire that are potentially influencing wine chemical composition.
