År 1855 klassificerades slotten i vindistriktet runt Bordeaux. Denna klassificering fick stort genomslag och används än idag. Klassificeringen har emellertid kritiserats för att ej representera den faktiska kvaliteten av dess innefattande viner. Trots det används den som ett facit över vinernas storhet. Detta arbete har undersökt samband mellan klassificeringen och vinernas kvalitet idag. Resultatet av litteraturstudien fann samband mellan bordeaux, pris och marknadsföring. Vidare redogörs för att begreppet kvalitet är svårdefinierat då flertalet aktörer tolkar kvalitet på skilda sätt. Influensen av terroir är ej utan vinmakaren en relevant faktor för de sensoriska egenskaperna i vinet. Faktisk kvalitet är mindre betydelsefullt än förväntad kvalitet ur ett marknadsperspektiv. Arbetet diskuterar kvalitetens förankring och vikt i klassificeringen från 1855. Marknadsföring är en stark variabel vid prissättning av viner från Bordeaux i vilken förväntad kvalitet vägde tyngst för priset. Vinkritiker är inflytelserika i en vinproducents förväntade kvalitet. Diskussionen behandlar även olika ståndpunkter i användande av begreppet terroir. De innefattande vinernas faktiska kvalitet var av mindre vikt när klassificeringen genomfördes. Rankningen har idag lett till en generellt högre kvalitet bland vinerna. Klassificeringen har även skänkt status åt regionen och dess viner. / B-uppsatser

Terroir combines the physical landscape of the vineyard with the grapevines and the methods and techniques used to produce wine from the grapes. This study used a GIS to identify the characteristics of the physical landscape in Pottawattamie, Mills, Montgomery, Fremont, and Page counties in southwestern Iowa. The components were combined in the GIS using a weighted linear index to identify areas suitable for vineyard development and to identify the general characteristics of the area. Vineyard owners were interviewed to help determine the weighting system to use in the GIS and to determine their perceptions of how the physical landscape impacts their vineyards, as well as to determine what grape varieties they plant in their vineyards and their decisions on making wine from these grapes. This information was collected to identify whether the vineyard owners had developed a sense of place for their vineyards and how this sense might aid them in the development of a terroir for their wines. The resulting perceptions about the individual wineries were then considered in conjunction with the results from the GIS modeling to understand how the physical landscape influences the concepts of sense of place and terroir in southwest Iowa. The physical landscape of southwest Iowa was fairly uniform, as were the grape varietals planted in the vineyards. This created a measure of similarity among the wineries, while individuality between wineries was then created by the wine-makers as they used different techniques to produce wine from the grapes. This allows each winery to develop a sense of place, yet be part of a larger sense of place that encompasses multiple wineries within the area.

L'économie algérienne est fortement dépendante, avec un commerce extérieur orienté principalement vers l'exportation des hydrocarbures. La perspective d'épuisement d'une telle ressource non renouvelable mène les économistes et les dirigeants à s'interroger sur l'avenir de cette économie et sur les voies et moyens de diversification. Les produits de terroir apparaissent comme une des solutions possibles du fait même de leur importance dans l'économie algérienne et de l'attachement spécifique des consommateurs de la diaspora à ces produits. La diaspora algérienne est en mesure d'impacter le processus de valorisation et de développement des exportations de ces produits de terroir vers les marchés internationaux. Ce croisement entre diaspora, commerce international et produits de terroir est l'apport principal de cette thèse sur le plan théorique. Cette mise en relation est également originale dans le contexte algérien et plus largement maghrébin, puisqu'il n' y a que peu d'études à ce sujet. Nous avons ainsi défendu la thèse que les produits de terroir pourraient constituer une voie de diversification du commerce extérieur algérien. Dans ce cadre, la diaspora est à même de jouer un rôle considérable à la fois dans la valorisation de ces produits et dans leur introduction sur les marchés internationaux. Nous avons appuyé notre démonstration par une démarche théorique et une méthodologie originale. Nos principaux résultats confortent cette thèse. Cependant, les contraintes institutionnelles et territoriales contrarient l'implication des réseaux diasporiques et freinent le processus de diversification et de valorisation des territoires. Il est à ce titre urgent de mettre en œuvre des dispositifs d'appui et d'accompagnement au profit des entrepreneurs, des territoires et de leurs produits de terroir. / The Algerian economy is highly dependent with a foreign trade oriented mainly to the export of hydrocarbons. The prospect of depletion of such a non-renewable resource lead economists and leaders to question the future of the economy, the ways and means of diversification. The local products appear as a possible solution because of their importance in the Algerian economy and the specific attachment of Diaspora consumers to these products. Algerian diaspora is able to impact the process of implementation and export development of these local products to international markets. This cross between diaspora, international trade and local products is the main contribution of this thesis in theoretical terms. This relation is also original in the Algerian and North African context, because there is little research about this. We have defended the thesis that the local products could be one way of diversification of the Algerian foreign trade. In this context, the diaspora is able to play a significant role both in the development of these products and their introduction in international markets. We supported our demonstration by an original theoretical and methodology approach. Our main results confirm this thesis. However, the institutional and territorial constraints, contradict the involvement of diaspora networks, slows the process of diversification and enhancement of territories. It this then urgent to implement support and guidance for the benefit of entrepreneurs, territories and local products.

The aim of this diploma thesis was the selection of appropriate indigenous yeasts for wine production. Tested yeasts were isolated from the grapes from the winery Maňák Žádovice. The yeasts isolated within theses in 2009 – 2012 have been also tested, and commercial wine yeast have been tested for comparison. In the theoretical part the focus is on the technology of wine, in particular fermentation. The work is also focused on yeasts metabolism and taxonomy. There was described the principle of PCR-RFLP, and methods used to characterize the properties of isolated yeasts. In the experimental part was made isolation of yeasts, theirs identification using PCR-RFLP and to select the most suitable yeast in wine making proces were performed physiological tests.

Aim of this thesis was to answer question how big is influence of geological and pedological conditions on qualitative parameters of wines. Four sites with variety Ryzlink rýnský have been choosen on vineyard Velká Vendule in Velké Žernoseky based on differect pedological a geological characteristics. Site have been closely described from pedological point of view. Wine samples from vintages 2012 to 2014 have been made from every site via unified vinification so 51 wine properities could be measured. Results have undergone canonical diskriminant analysis. It was found content of elements in soil isn't in clear relation to content in wine, mainly because different climatic conditions each year. In spite of this it was possible to clearly separate all wine samples by sites by chossing selected parameters (D/H)II, 13C, B, Ca, K, Mg, P, catechin a trans-piceid. They could be therefore called markers for tracking wine authenticity in relation to geological and pedological conditions.

My thesis deals with various methods of fermentation of grape must. Describes unique methods of inoculation, yeast, alcohol fermentation, and terroir. A two-year experiment was made with samples of wines made from the same varieties. The difference in production was only the inoculation of the must. The other steps in wine making were the same, so that the only difference in the produced wine was the method of inoculation. The results obtained are clearly elaborated and evaluated, including aroma-profiles and wine profiles.
