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

Abstract

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 and to compete with a growing number of cultural sites, also classified by UNESCO. To achieve this goal, landscape managers and public authorities have much to profit from knowing and understanding visitors’ preferences regarding the attributes associated to its outstanding universal value. 

The goal of this paper is to enhance the knowledge about the preferences of the ADWR Portuguese’ visitors, considering the attributes that deserve preservation and consequently public attention. Using the choice experiments technique, six alternative choice sets were presented in a questionnaire in the year 2013. Data was collected from 249 useful surveys corresponding to 1,494 responses. Responses are analyzed by a random parameters or mixed logit model, taking into account the random preferences heterogeneity and the panel nature of the data. 

An additional and innovative issue of the article is to compare the results of the survey conducted in 2013 with previous evidence from own work conducted in 2008. The comparison of the results in two distinct periods of time is a novelty; moreover the question of preferences’ stability has rarely been addressed in discrete choices models. Nevertheless, in the context of changing living conditions and expectations of Portuguese consumers plunged into an economic crisis, this subject is clearly relevant.

Oenological potential of indigenous greek grape varieties and their clones

Vine clone selection aims at the survival of clones with particularly desireable attributes for the production of high quality wines. The purpose of this research was to study the enological potential of the clones of Greek indigenous grape varieties over two vintages, 2018 and 2019.
METHODS: Two clones of the white grape varieties Moschofilero (E26 and E27), Assyrtiko (E11 and 16), Roditis (25E16 and 02E1E21) and two clones of the red grape varieties Xinomavro (19 and E2E30) and Agiorgitiko (03E40 and 41E47) were vinified under the same protocol for the white wines and common for the red wines in 2018 and 2019. The resulting products were studied for several enological parameters such as alcohol content, volatile acidity, pH, total phenolics, anthocyanins and tannins for the red wines, as well as browning tests for the white wines. The aroma profile of these ten samples was investigated through sensory analysis with intensity rating of individual attributes on a five-point scale by a trained panel.

The affinity of white wine proteins for bentonite is dependent on wine composition and is directly related to their thermal stability / sensitivity

Bentonite fining is commonly used in oenology to remove all or parts of white wine proteins, which are known to be involved in haze formation. This fining is effective, but has disadvantages: it is not selective, thus molecules responsible for aroma are also removed, it causes substantial volume losses, and finally it generates wastes. Over the last decades, the knowledge of wine proteins has increased: they have been identified, their structures are known, some of them have been crystallized.
