In action: the video from my talk on minerals and terroir in Barcelona

So the video of my talk from the Wine and Culinary Forum (nice review of the forum here from top Canadian wine journo Treve Ring) is finally live and posted to Youtube. Here it is:

 

The effect of herbicides on soil structure

I’m just preparing a presentation I’m giving in the Netherlands tomorrow, and I came across two pictures I took in the vineyards at Waterkloof in Stellenbosch, South Africa. The first is of one of their vineyards that has been managed biodynamically from the start, which is above. [It's not an old vineyard.] The soils had [...]

Comparing the same wine sealed with cork and screwcap

The closure debate has moved on quite a bit since the days when it was practically pitched warfare between the screwcap advocates (mainly Australia and New Zealand) and those who liked the traditional solution of natural cork. Now there’s a sort of truce.

For commercial wines, few have a problem with screwcaps. They’re taint free, they [...]

Pressing under nitrogen, the Inertys system

One of the things I saw in Provence was the way that many of the wineries are projecting the juice by pressing in the absence of oxygen. Pictured above is the press at Chateau Gassier, which has been fitted with the Bucher Inertys system.

The big bag (pictured below is one at Chateau Jas d’Esclans) [...]

Research suggests fruit flies could be responsible for wine's pleasant aromas

Could fruit flies be responsible for the nice smell of most wines? This is a really interesting idea suggested by a research paper just published in scientific journal Ecology Letters. It’s by a New Zealand group, led by Dr Mat Goddard, who have already published some really interesting research on yeast ecology, showing that the [...]

Some thoughts on GM technology

York Station

So yesterday I took part in a careers session for the brightest and best undergraduates in plant sciences at the Gatsby summer school. Held at the lovely Hawkhills centre near York, the idea is to enthuse these students about a potential career in plant sciences, and area which is vitally important but which [...]

The new edition of my book Wine Science/The Science of Wine

I’m delighted to say that if you are as nerdy about wine as I am, there’s a new book coming out next month that will be just up your street.

OK, I am a little biased. It’s the new version of Wine Science, which in the USA is published as The Science of Wine. Both [...]

Wine and music, a scientific study

It is well known that context can affect our experience (and enjoyment) of wine. But how do you measure this?

In a paper published in open access scientific journal Flavour, Charles Spence, Ophelia Deroy and colleagues looked at potential crossmodal correspondences between classical music and fine wine. To put this more simply, does listening to music [...]

What is a grape variety? What is a clone?

We talk a lot about clones and grape varieties. But what, precisely, do these terms mean?

Let’s first define ‘variety’. A new grape variety is produced when a grape seed has grown into a plant. So the 1500 or so commercial varieties of the single species Vitis vinifera grown worldwide are all the result of the [...]
