Climate change could impact the microbial make-up of wine, according to New Zealand researchers. Wine scientists from Lincoln University analysed the bacteria and fungi present during the fermentation of two organic Pinot noir batches from the same winery, and discovered significant differences between the 2018 and 2021 vintages correlating to differences in climate data. The study highlights how year-to-year variations in temperature and humidity affect wine fermentation, as well as the potential long term impacts of climate change on wine production and quality control in Aotearoa.
