Establishing the concept of terroir in wines, combined with the exploitation of native grape varieties, is considered a viable alternative to produce quality wines for increasing interest in the wine market. The aim of this study is the characterization of Protected Geographical Indication (PGI) Savatiano white wines from different regions of Attica (Greece), through the chemical and sensory description of the aroma of wines and the determination of their phenolic profiles. The wines produced with the same vinification protocol were evaluated using the descriptive sensory analysis method while they underwent profiling of volatile and phenolic compounds by gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) respectively.

- Studies over the past ten years indicate that biostimulants can enhance grape and wine quality by affecting the metabolism of grape berries.
- This research specifically focused on how two biostimulants—abscisic acid and chitosan—impact phenolic compounds in the Savvatiano grapevine at different growth stages.
- Results demonstrated that both treatments increased anthocyanin and stilbenoid levels and positively influenced the expression of related biosynthesis genes, suggesting that these biostimulants could improve grape quality and defense mechanisms.
Wines produced from autochthonous varieties have an essential financial impact on the national economy of Greece. However, scientific data regarding characteristics and quality aspects of these wines is extremely limited. The aim of the current study is to define the molecular profile and to describe chemical and sensory characteristics of the wines produced by two autochthonous red grapevine varieties-"Karnachalades" and "Bogialamades"-grown in the wider area of Soufli (Thrace, Greece).

Spread of the disease is dependent on complex interactions between insect, plant and phytoplasma. In the Piemonte region, wine production is based on local cultivars.

The aim of this work was to evaluate the activity of BTH in preventing FDP transmission by the insect vector and in inducing recovery of infected grapevines.
Results: Repeated 2 mM applications of BTH to test grapevine cuttings (cv.
