The Soil Component of Terroir

Abstract

Evidence for a specific effect of soil mineral composition on wine character is largely anecdotal. However, soil potassium supply to the vine must be properly balanced between deficiency and excess for good fruit quality. Nitrogen supply interacts with soil water to affect vine vigour, yield and fruit quality. With irrigation, water availability in the top 40-60 cm of soil can be managed through regulated deficit irrigation, thereby subduing the mineralization of soil organic N and decreasing vine N uptake, with favourable effects on fruit quality. In dry land vineyards, water availability depends on climate and soil physical properties, the latter being beneficially modified by calcium. The effect of soil variation on terroir should be evaluated on a scale of metres rather than kilometers. High density real-time measurements of relevant soil properties enables digital soil mapping at very high resolutions. Thus, vineyards can be divided into small blocks with the same mesoclimate allowing site-specific soil management and cultural operations (precision viticulture).

Exploring diversified service offerings in the Spanish wine industry

The spanish wine industry stands at a crossroads, transitioning from a traditional emphasis on wine production to a landscape increasingly characterized by diversified service offerings. This paper delves into the nuances of servitization within spanish wineries, investigating the determinants of servitization and the impact of these diversified services on revenue streams. The paper posits hypotheses concerning the influence of various factors, such as winery size, location, market orientation, ownership structure, market competition, regulatory environment, market demand, firm capabilities, owner characteristics, and firm age, on the adoption of diversified service offerings in spanish wineries. The methodology involves comprehensive regression analysis to unravel the drivers of servitization within this context.

The potential of new selection and indigenous grape varieties for sparkling wine production

In the context of climate change, it is essential to provide producers with alternatives based on local grape varieties capable of meeting modern quality and sustainability requirements.

Aroma characterization of aged cognac spirits: contribution of volatile terpenoid compounds

Cognac spirit aromas result from the presence of a wide variety of volatile odorous compounds associated with the modalities of distilled spirit elaboration and during aging. Indeed, these odorous compounds play an essential role in the finesse and complexity of the aged Cognac.

Pierce’s disease of grapevines, a new threat to the wine industry in Southern Europe

Pierce’s disease (PD) is considered a potential threat to european viticulture (EPPO a2 list of pathogens since 1981). In the usa, infections caused by the vector-borne bacterium xylella fastidiosa have caused recurrent damage to vineyards in California and the southeastern states. However, vineyards in Europe have remained free of PD until recently, when it was first detected on the island of Mallorca in 2017. The reasons for the absence of PD in continental Europe have not been convincingly explained.

Exploring the behavior of alternatives to montmorillonite clays in white wine protein stabilization

Visual clarity in wines is crucial for commercial purposes [1]. Potential protein haze in white wines remains a constant concern in wineries, commonly addressed using bentonite [2].
