Wines of Fire and Earth: Exploring the Volcanic Terroirs of the Canary Islands – a Case Study

Abstract

The Canary Islands, an Atlantic archipelago of volcanic origin, offer an extraordinary case study of the interplay between geology and viticulture. Forged by millennia of hotspot volcanism, these islands boast dramatic landscapes characterized by volcanic soils (picón), microclimatic diversity, and ecological richness. This unique confluence of natural factors has not only shaped the environment but also defined the character and identity of the region’s wines. This article delves into the volcanic terroirs of the Canary Islands, with a particular focus on the iconic regions of Lanzarote and Tenerife. Through a multidisciplinary approach encompassing geology, viticulture, and oenology, we aim to unravel the complexities of these volcanic vineyards. We explore how the islands’ geological legacy and microclimatic nuances influence vine cultivation practices, enhance the organoleptic properties of the wines, and contribute to a viticultural identity that is as distinctive as it is resilient. From Lanzarote’s La Geria, where traditional practices transform volcanic ash fields into strikingly innovative vineyards, to Tenerife’s ancient grape varieties thriving on terraced slopes, the Canary Islands demonstrate a remarkable synergy between human ingenuity and natural beauty. These vineyards, integral to the Canarian landscape, are a testament to the enduring relationship between cultural heritage and ecological sustainability. In this study, we examine the challenges and opportunities facing this viticultural heritage, while offering insights into its potential for innovation and sustainability in an evolving global wine market. The region’s success is presented as a blueprint for sustainability in the face of global climate change through maintaining high-quality, distinctive wines applying organic and biodynamic methods. The most important scientific contribution of this case study is the holistic, ecosystem-centred analysis of this unique viticulture in terms of ungrafted vine cultivation, the significant gene-bank potential of the ancient grape varieties, the possibilities of developing organic circular bioeconomy-based viticultural practices in extreme wine terroirs, and the mitigation of the adverse impacts of climate change. Furthermore, by bridging ecological, agricultural, oenological, and economic perspectives, the profound impact of isolated volcanic terroirs on the Canary Islands’ viticulture and winemaking and their unique contributions to the broader world of viticulture is presented.
