Similarities among wine aromas and landscape scents around the vineyard in five Mediterranean sites

Abstract

We compared 68 aroma compounds in wines from 5 vineyards in order to see similarities among the wine aroma and the scent of some of the main native plants from the respective vineyards. The work started with characterising the plant vegetation and the main plants and herbs in the boundaries and field growing in each 5 selected vineyards in Catalonia, Spain. Then 3 wines from each vineyard were analysed for aroma compounds and sensory description. In spring-early summer of 2021, 168 plants were recognised in the prospected sites. We found differences in the plant species diversity that characterised each vineyard landscape. Each vineyard had a particular set of plant species with a unique mix of aroma compounds. We compared the aromas of the wines and the aromas of the plants and found several matches among them. Further studies may offer a better understanding but it seems to be a connection or similarity among the landscape’s aroma and the wines obtained in proximity. Among the compounds with the highest odorant value found are the nosioprenoids ionone and damascenone and terpenes with floral and fruity aromas. This research allows a better understanding of the landscape and wines and to visualize the importance of preserving biodiversity as a management criteria and highlight its value in the vineyards. It can also be a tool for communication between the winemaker and the consumer.

The Hungarian system of geographical indications and the preparation of product specifications

Following the 2008-2009 reform of the European Union’s common market organisation in wine all protected designations of origin and geographical indications were imposed to prepare a product specification that described the conditions of their use. In this paper, we describe this process and the Hungarian system of geographical indications.

Fertilization with Seaweed (Laminaria japonica) on the characteristics of the bunch and the quality of the grape must of ‘Cabernet Sauvignon’

The objective of the present work was to study the influence of the foliar application of seaweed (Laminaria japonica), on the bunch and on the must in the ‘Cabernet Sauvignon’ grape. The experiment was carried out in the years 2021/2022, in a 21-year-old commercial vineyard, in the municipality of “Dom Pedrito” – “Rio Grande do Sul” (RS). A completely randomized experimental design was used, with 4 treatments and 4 replications (7 plants per replication). The treatments were: T1- control treatment; T2- Exal Powder 5 g L-1; T3- Hidro Exal 15 ml L-1; T4- Exal Powder 5 g L-1+ Hidro Exal 15 ml L-1.

Anti/prooxidant activity of wine polyphenols in reactions of adrenaline auto-oxidation

Adrenaline (epinephrine) belongs to catecholamine class. It is a neurotransmitter and both a hormone which is released by the sympathetic nervous system and adrenal medulla in response to a range of stresses in order to regulate blood pressure, cardiac stimulation, relaxation of smooth muscles and other physiological processes. Adrenaline exhibits an effective antioxidant capacity (1). However, adrenalin is capable to auto-oxidation and in this case it generates toxic reactive oxygen intermediates and adrenochrome. Under in vitro conditions, auto-oxidation of adrenaline occurs in an alkaline medium (2).

Soil monoliths, soil variability and terroir

Aim: The aim of this work is educating people about soil variability and terroir. Soil monoliths are used to educate the wine industry about how to describe a soil profile, interpret the soil formation processes operating in a particular soil profile and consequently the impact of soil properties on vine growth, fruit quality and wine production. Soil monoliths are a permanent artistic tool for educating, research and management of soil variability.
