Mapping natural terroir units using a multivariate approach and legacy data

This work aimed at setting up a multivariate and geostatistical methodology to map natural terroir units of the viticultural areas at the province scale (1:125,000).  The methodology was based upon the creation of a GIS storing all the viticultural and oenological legacy data of experimental vineyards (1989-2009), the long term climate data, the digital elevation […]

Harvest dates, climate, and viticultural region zoning in Greece

Climate is clearly one of the most important factors in the success of all agricultural systems, influencing whether a crop is suitable to a given region, largely controlling crop production and quality, and ultimately driving economic sustainability. Today many assessments of a region’s climate comes from a combination of station and spatial climate data analyses […]

Time stability of visitors’ preferences for preserving the worldwide cultural landscape alto douro wine region

The Alto Douro Wine Region (ADWR) was classified a world heritage site, specifically as a cultural landscape, by UNESCO, in 2001. The well known “Porto Wine” and other high quality wines are produced in the Douro region. As an attraction and touristic site, the cultural site has to meet the needs of more demanding visitors […]

The vine and the hazelnut as elements of characterization of a terroir

The research examines how two characteristic cultivations of a territory like the vine and the hazelnut shape the identity of a unique terroir: Langhe (North West italy).  The two cultivations are part of important agri-food chains for the analysed territory and its economy, while they also model its landscape.  The vine represents a Universal Value […]

About long time and vine quality modelisation e pistemological appro ach to geographical viticulture

This work began as an intellectual game, in order to discuss the notion of wine quality in terms of terroir and territory spatial structure. Vine and wine quality has long been questioned by scientists. Each discipline approaching it with his own tools. One of Frenchs geographers who mark the discipline history was Roger DION(1896-1981) whit […]

The effect of pedoclimatic conditions on the yeast assimilable nitrogen concentration on white cv. Doral in Switzerland

 Aims: Agroscope investigated the efficiency of nitrogen fertilization via foliar urea application at veraison with the aim of raising the YAN (yeast assimilable nitrogen) content in the musts. The observations were conducted on the white grapevine cultivar Doral (Chasselas x Chardonnay) in several pedoclimatic conditions of the Leman wine region, Switzerland, in the years 2012 […]

Terroir influence on growth, grapes and grenache wines in the AOC priorat, northeast Spain

The Mediterranean climate of The Priorat AOC, situated behind the coastal mountain range of Tarragona, tends towards continentality with very little precipitation during the vegetation cycle. The soil is poor, dry and rocky, largely composed of slate schist, known as “llicorella”. Vines primarily grow on steep slopes and terraces. To evaluate how the Priorat unique […]

Temperature effects on the biosynthesis of aroma compounds in glera grapes

This paper describes the first year results of a study that investigated the effects of altitude and related temperature parameters on the biosynthesis of aromas in the Italian cultivar Glera.  The trial was carried out in a commercial vineyard planted on a steep slope in the Valdobbiadene area (North-East of Italy). Three sites were selected […]

Spatio-temporal analysis of grapevine water behaviour in hillslope vineyards. the example of corton hill, Burgundy

Hillslope vineyards show various and complex water dynamics between soil and plants, and in order to gain further insight into this phenomenon, 8 grapevine plots were monitored during three vintages, from 2010 to 2013, on Corton Hill, Burgundy, France. Plots were distributed along a topolithosequence from 330 to 270 meters asl. Grapevine water status was […]
