Exploring the Relationship Between Grape Quality and the Microclimate in Madeira, Portugal

Abstract

Landscape characteristics affect vineyard microclimates and influence the quality of grapes produced. There is currently a lack of research examining the microclimatological conditions of vineyards and how they affect grape quality. This study utilizes qualitative methods to explore the relationship between vineyard microclimates and grape quality in Madeira, Portugal. Semi-structured interviews have been conducted with local participants involved in the production of wine grapes and are used to reveal the factors affecting grape quality. Interviews accompany a physical inventory of landscape characteristics in the vineyards, and are guided by where interviewees observe changes in grape quality. The findings suggest there is a strong relationship between microclimates and grape quality. These results are utilized to make recommendations for methods of site selection and the microclimatic design of vineyards.
