Following the tweet stream for Monday’s talks.

Day two of the congress opens. I’m compiling the tweets from the UK, so I’m entirely reliant on the people below for today’s coverage and there’s some problems with that.
Anyone got any suggestions for how to juggle twenty competing symposia? What if two of your botanical idols are speaking at the same time? I think I’ll just plan one day ahead and hope to avoid brain overload.

So I’ve opened the program and I’ll try to follow the sessions as best I can. The first plenary lecture was Professor Else Friis, who’s been working with Peter Crane with a talk The ‘abominable mystery’ solved – the origin of flowering plants.
Two of the best coffees I’ve had for…oh…4 months? But the abominable mystery of first plants has drawn me back from city cafes. #ibc18

Vineyards record harvest dates & sugar, alcohol levels, with some Australian records going back 100+ years #ibc18

Coonawarra wine maturity dates are moving earlier at a rate of about 3.8 days per year #ibc18

IPCC estimates 2 to 4 degrees of global warming, need to bring that down to a local level to predict the effects on vineyards #ibc18

Each grape varietal requires right terroir. Too warm = too much sugar, not enough acid. Too cool = decreased sugar, unripe flavours #ibc18

Compounds giving wine it’s flavour now being found. These differ between seasons, some eg rotundone not detected in warm years #ibc18

Australia can move varieties to suitable climates. Appellation contrôlée in France won’t allow adaptive management & varietal change #ibc18

Appellation control only allows certain grape varietals. Climate changes may mean they’re no longer suitable to those regions #ibc18

Challenge is to identify dominant flavour compounds that give wine distinct character & examine how temp influences their production #ibc18

Methoxypyrazine provides grassy flavour in sauvignon blanc & is at 10-30ng/L in Marlborough wines, but much lower in Aust wines #ibc18

Rotundone, the black pepper flavour in shiraz, is up to 600ng/L in cool climate wines, but undetectable in wines from Rutherglen #ibc18
