“…Although maximum temperature may explain a great deal of current yield variability, around 40% remains unexplained, indicating other critical climate variables, such as precipitation, soil moisture, and sunshine hours [58][59][60], may be important as well as weather conditions during fowering and harvest [61], which have not been considered here. Consequently, their role is worth exploring in future studies of contemporary yield sensitivity, along with the types of large-scale weather patterns that might be pivotal in infuencing annual wine yield and frost occurrence, as found elsewhere, for example in Sturman and Quénol [53].…”

Background and Aims. The cultivation of grapevines in England is expected to benefit under climate change. Yet assessments of future wine climates remain undeveloped. Accordingly, this study assesses how climate change might modify frost risk for Chardonnay in the Southeast England viticulture region. Methods and Results. Cold-bias-corrected climate projections from the UKCP18 Regional (12 km) perturbed parameter ensemble (PPE) climate model under RCP8.5 are applied with phenological models to determine how frost risk and the timing of key grapevine phenophases might alter under climate change. Notwithstanding the uncertainties associated with projections of key viticulture-related bioclimate variables, the last spring frost was found to advance at a greater rate than budburst, indicating a general decrease in frost risk. Conclusions. Although projections point to an improving climate for viticulture across Southeast England, frost will remain a risk for viticulture, albeit at a reduced level compared to the present. Furthermore, the strong cold-bias found for temperature simulations used in this study needs to be given careful consideration when using the UKCP18 projections for viticulture impact assessments of climate change. Significance of the Study. This study highlights the present sensitivity of viticulture to climate variability and the inherent uncertainty associated with making future projections of wine climate under climate change.

“…Though the amount of UK land area deemed capable of producing Good wine by the Model (Biss and Ellis, 2021) was generally lower (by 0.1 to 9.2 %) than that suggested by using the simple 14 °C GST threshold (Jones, 2006(Jones, ) for 1981(Jones, -2000(Jones, , 2010(Jones, -2019(Jones, , 2012(Jones, and 2018, the two methods produced similar distributions of land with suitable climates (compare Figures 3 and 4).…”

“…Viticulture is changing substantially as the world warms. Phenology is advancing (Quénol et al, 2017) and growing seasons are lengthening (Jones and Davis, 2000), all of which can impact yield, quality and wine characteristics (Jones, 2007;Quénol et al, 2017). Wine producers in traditional viticulture regions in Europe are concerned with mitigating the negative impact on their crops from factors such as heat stress and drought (Jones and Schultz, 2016) and are considering how to adapt to future climate change (Neethling et al, 2017).…”

Weather potential for high-quality still wine from Chardonnay viticulture in different regions of the UK with climate change

UK viticulture is benefitting from climate change with an increase in vineyard area and a move towards French grapevine varieties, primarily Chardonnay and Pinot noir, to produce sparkling wine. Doubt remains, however, as to how good UK still wine can be from these varieties. The simple Chablis vintage model uses only three climatic indices: mean temperature from April to September, mean minimum temperature in September (cool night index) and total rainfall from June to September. It was applied to the UK for the periods 1981–2000, 2010–2019 and, with climate change projections, to 2040–2059 to locate sites in the UK with the climate potential to produce high-quality Chardonnay still wine. Weather data for 1981–2000 and 2010–2019 were taken from the Met Office’s HadUK-Grid at a resolution of 5 × 5 km, and climate projections for 2040–2059 were derived from UKCP18, using intermediate emission scenario RCP 4.5 at the 5th, 50th and 95th percentile probabilities. Recent and current climatic conditions throughout most of the UK were unsuitable for sustainable production of high-quality still Chardonnay wine (only 0.2 to 1.8 % of UK land area suitable), but model scores corresponded with high-quality Chardonnay still wine production observed in some regions of England in 2018. Under the 5th percentile RCP 4.5 projection for 2040–2059, climatic conditions are similar to 2010–2019 and generally unsuitable for sustainable, high-quality still Chardonnay wine production. Under the median and 95th percentile projections for 2040–2059, however, South East England and East of England have the potential for high-quality still Chardonnay wine production in an average year, and Central England also with the 95th percentile projection. Overall, climate change is expected to benefit the production of high-quality still Chardonnay wine in the medium term, with up to 42.4 % of UK land possibly climatically (but not necessarily agronomically) suitable by mid-century. The model does not account for extreme events, however, and there is uncertainty over future inter-annual weather variability, and so the sustainability of high-quality still wine production. Planting Chardonnay clones suitable for both sparkling and still wines in the most-suitable areas of England would provide flexibility and so resilience.

“…The effects of individual weather variables on grape-and thus wine quality, have been subject to many attempts of quantification, particularly so in Bordeaux (France) where researchers can draw on an abundant corpus of data. The average temperature during the grapevine (Vitis vinifera) growing season, from April to September, has been identified as the main driver of wine quality in Bordeaux before the year 2000 (Jones and Davis, 2000;Ashenfelter, 2008), as is the case in other regions (Byron and Ashenfelter, 1995;Haeger and Storchmann, 2006;Corsi and Ashenfelter, 2019;Biss and Ellis, 2021). Indeed, low temperatures are linked with low sugar levels, which often coincide with poor vintage ratings in Bordeaux (Gambetta and Kurtural, 2021).…”
