How much does vine transpiration increase during a heat wave? To address that question, a team of Australian researchers led by Edwards reported the following observations in 2011.While working in a greenhouse with Cabernet Sauvignon, researchers generated  a 2-day high-temperature event by imposing maximum daytime temperatures near 41°C.  Before imposing the […]

The purpose of stratified sampling is to remove sources of noise when collecting vineyard data. In turn, analyzing  “cleaner” data improves the ability to monitor vineyard performances precisely. To implement a stratified sampling strategy, it is necessary to focus: over a small vineyard area so we can remove the effect […]
