There’s been a lot of talk about the biodynamic calendar in the wine trade. At wine tastings, it’s not unusual for tasters to start muttering that the wines aren’t showing very well. Then someone whips out their smartphone. ‘I thought so!’ they proclaim. ‘It’s a root day.’
For those unfamiliar with the concept, I’m referring to [...]
When it comes to vineyard soils, limestone is all the rage. But there’s one source of limestone in vineyard soils that isn’t much talked about. It’s the slow formation of limestone in arid vineyard soils, known as pedogenic lime (and alternatively caliche and calcrete). I first encountered it in Central Otago, and then bumped into [...]
There’s a very interesting article on Jancis Robinson.com today, in which she reports on a recent Institute of Masters of Wine (IMW) seminar on mineralogy. It deals with some very interesting issues. In her piece, she reports on Maltman’s talk, but I think she jumps to too-hasty a conclusion about its implications.
As geologist Alex Maltman [...]
Are organic wines better than conventional ones? An interesting study from researchers at the University of California Los Angeles suggests that they might well be. However, the difference in point scores between eco-certified wines and conventional wines is actually much smaller than press reports on this study have stated, because they haven’t read the paper [...]
This is a question that I think is really interesting, and it would be quite easy to answer. How stable is our olfactory ability over time?
We each differ in the set of olfactory receptors that we express in our nasal cavity. These receptors detect smell molecules. But there are far more smell molecules that we [...]
So, I rolled into Adelaide airport at 8 pm on Sunday night, after a long flight from London via Dubai. On the plane I alternated between sleeping, working, and listening: of late, I have taken to listening to music on flights. Usually, new planes with decent in flight entertainment have a good selection, and if [...]
I’m at the Riesling Rendezvous conference in Seattle, Washington State. Held every three years, it’s an in-depth dive into this most distinctive of white wine grapes. It began on Sunday evening with a grand tasting outdoors at Chateau Ste Michelle in Woodinville, and yesterday and today we’re in Seattle for tastings and seminars.
One topic that [...]
Gary Pickering, of Brock University presented a talk at the ICCWS (International Cool Climate Wine Symposium) on managing green flavours in wine. These are largely (but not exclusively) caused by methoxypyrazines. The two main ones in wine are isopropyl methoxypyrazine (IPMP) and isobutyl methoxypyrazine (IBMP).
There’s a level at which these green flavours can be typical [...]
Alistair Nesbitt, from the University of East Anglia, has created a model that maps spatial climate variability in the UK, showing the suitability of various areas for viticulture in England and Wales. Over the period 1954-2015 there has been a non-linear warming trend for the growing season, and the amount of variability from season to [...]
Framing is a social science term which refers to a set of concepts and perspectives that then form the background that influences how we think on certain issues. In this sense, framing is part of the narrative structure with which we see the world. American academic and author George Lakoff has popularized the term in [...]
