data

The first subset was created by digitizing and curating the seminal report of Amerine and Winkler (1944), which provided grape harvest dates (GHDs), the quality of musts and wines, and wine tasting notes for 148 cultivars from 1935-1941 across five contrasting climatic regions of California. To put this dataset into a climate change context, we collected GHDs and must oBrix records from 1994 to 2018 for four representative cultivars in one of the five studied regions (Napa). Finally, we integrated meteorological data of the five regions during 1911-2018 and calculated bioclimatic indices important for grape. The resulting database is unique and valuable for assessing the fitness between cultivars across environments in order to mitigate the effects of climate change.

首个子集通过对Amerine与Winkler于1944年发表的开创性报告进行数字化处理与人工整理构建而成，该报告涵盖了1935年至1941年间加利福尼亚州5个气候迥异产区内148个葡萄栽培品种的葡萄采收日期（GHDs，Grape Harvest Dates）、葡萄醪与葡萄酒的品质，以及葡萄酒品鉴笔记。为将本数据集纳入气候变化研究语境，我们针对5个研究产区之一的纳帕（Napa），收集了1994年至2018年间4个代表性葡萄栽培品种的葡萄采收日期与葡萄醪白利度（oBrix）记录。最后，我们整合了5个产区1911年至2018年的气象数据，并计算了对葡萄种植至关重要的生物气候指数。最终构建的数据库具备独特性与重要应用价值，可用于评估各栽培品种在不同环境下的适配性，从而助力缓解气候变化带来的影响。
