High rainfall in winter may produce better grapes because if “the plant’s water reserves are filled up in winter, it can draw on that in spring and grow more vigorously”, says Wood. It may also lower soil salinity, so that less salt ends up in the grapes, he says. grapes, says Wood. Warm temperatures further assist the development of these flavour components by increasing photosynthesis, he says.The researchers found that critics’ ratings of Bordeaux wines have generally increased since 1950. This may be thanks to technological improvements in wine-making and efforts to match consumer preferences, but also because
