A Viticultural Terroir in Brazil: Change and continuity

Soil and climate maps at the 1:10000 scales exist for more than 12’000 ha of Swiss vineyards. The use of these maps as consulting tools for growers remains difficult due to the complexity

In a climate change context and aiming for sustainable, high-quality Bordeaux wine production, this project examines the impact of grape maturity levels in various cultivars chosen for their adaptability, genetic diversity, and potential to enhance wine quality. The study explores the effects on wine compo-sition and quality through sensory and molecular methods. We studied eight 14-year-old Vitis vinifera cv. grape varieties from the same area (VITADAPT plots 1 and 5): Cabernet Franc, Cabernet Sauvignon, Carmenère, Castets, Cot, Merlot, Petit Verdot, and Touriga Nacional.

Armenia, a small country in the South of the Caucasus, has been rediscovering its wine-growing past since the discovery in 2007 of archaeological wine-growing remains dating back around 8,000 years. They are among the oldest in the world. Despite a great diversity of grape varieties, Armenian winegrowers did not have sufficiently organized genetic collections to produce plants and satisfy the growing demand for planting.

Interest and willing-ness to buy alcohol-free wines by customers is increasing for several years [1]. Due to the rising relevance of dealcoholised wines it is the objective of this study to contribute to a better understanding of the flavor variation among dealcoholised wines and to explore enological measures, how to improve final quality.
First a range of commercial, alcoholfree white wines were analysed by the holistic sensory method projective mapping, including a question for hedonic acceptance. Based on the combination of a non-target-HS-SPME-GC/MS analysis with sensory analysis we obtained a clustering of the wines into three groups.

A foresight study was carried out by a group of experts from INRAE, universities, INAO and FranceAgriMer from 2014 as part of the multidisciplinary “laccave” project intended to anticipate climate change in the French wine industry. The initial objective was to initiate an interdisciplinary dialogue between researchers and to feed their questions in a more systemic way. The scenario development method made it possible to build possible futures for the wine sector in the face of climate change. It began by drafting four adaptation strategies, combining different possible intensities of innovation and relocation of the vineyard.
