    Global temperatures and the frequencies of heatwaves and drought events are increasing due to climate change. This challenges the wine industry, since
    temperature and water are important factors affecting the growth and physiology of grapevines. Particularly, berry ripening under stressful conditions could
    result in substantial loss of mass due to cell death within the berry and shrivel, which may negatively affect grape quality and lead to higher alcohol wines.
    We hypothesised that high temperatures may lead to oxygen deficiency (hypoxia) within grape berries due to the greater demand for oxygen by respiration,
    and also reduced oxygen diffusion within the berry due to water stress.
