GIS dataset locating suitable sites in England for high-quality Chardonnay viticulture: climate, topography, and soils (2010–2019, 2040–2059 RCP4.5)

This dataset provides GIS files from an assessment of site suitability for Chardonnay viticulture in England, aimed at identifying locations capable of producing premium single-varietal still wines. The modelling framework uses the Chablis region (France) as an analogue for climate and topography, with additional consideration of soil suitability. Climate conditions are presented for two periods: 2010–2019 (representing current conditions) and 2040–2059 (RCP 4.5, median and upper projections). For each scenario, mean vintage scores were calculated using the Weather Model of Biss and Ellis (2021, 2022). Land suitability is further classified into four categories – Unclassified, Village, Premier Cru, and Grand Cru – based on the combined effects of topography and soils.
