What makes a leader of a field, a leader? They have a brain, and not always, but sometimes, they can reason. So it’s not surprising that some leaders see through the fog. Here’s another example of how the truth gets out. It’s a specialist field, and newspaper stories are all doom and gloom (eg. Climate change threat to Australia’s top wines! ) but one of its most esteemed leaders is saying emphatically: not so.

“The effects of climate change have been dramatically over-estimated. Future global climate change caused by human activity will be much less than feared and be largely benign for viticulture”. “The 21st Century will be wine’s golden age”.

In viticulture, tiny changes in levels of part-per-trillion molecules produce prizewinners (or not). See Croser’s review to appreciate just how much. They don’t just talk in degrees but the number of days involved.

“…the quantum and quality of the tertiary aroma and flavour compounds synthesised is profoundly influenced by atmospheric temperature.    John Gladstones identifies the optimal mean temperature of the last 30 days of ripening for the synthesis of flavour and pigment in red varieties as 18-22ºC and for [...]
