Free the grape!

I blogged a few weeks back about the shift in the approach being taken in Europe to protect traditional farmers and producers — and the agrobiodiversity which underpins their livelihoods — in the face of globalization. Rather that erecting subsidies and tariffs to compete on price, the idea is to move upmarket and sell expensive niche products to rich foreigners. Of course, that requires a quality control and labelling system, such as appellations of origin (aka geographical indications).

Well, there’s a downside to such systems. I was idly going through my feed reader today and I ran across an old post on The Fruit Blog (a great blog which unfortunately seems to have gone dormant of late) which pointed to a 2004 article in the International Herald Tribune about how legislation is being used in Europe to basically outlaw some old American grapevine varieties:

The story has been all but forgotten in France today except among a handful of wine experts and a gaggle of bureaucrats who enforce the law. The French government banned wine made from American grape varieties on the grounds that it tasted like raspberries and was thus offensive to the palate. The European Commission adopted the French rule in 1979, making it illegal to grow these varieties anywhere in the European Union.

The percentage of outlawed American grape varieties is relatively small in France. But the offending vines are also sprinkled widely throughout several East and Central European countries that have recently joined or will soon join the European Union.

“You can’t tell the Hungarians, Bulgarians and Romanians to uproot their vines,” says Pierre Galet, perhaps the world’s leading expert on grape varieties. He believes the ban on American varieties is anachronistic.

Shades of what Jeremy has called Europe’s draconian seed laws. The US, in contrast, is not shy about mixing up the American and European grapevine genepools (I have blogged about this before: funny how much I write about wine).

As I say, the IHT article is a few years old, and things may have changed. Something is afoot in the EU with regards to wine legislation, but I wasn’t able to find any more recent analysis of the specific issue of the old American varieties. If you know the latest Brussels scoop on this, let us know.

Herbal remedies

ResearchBlogging.orgAromatic agrobiodiversity was in the news and the peer-reviewed literature today. Rosemary (Rosmarinus officinalis) got a good write-up in ScienceDaily. It turns out that one of chemicals found in its spiky leaves — carnosic acid — can protect the brain from free radicals, but is only activated by the damage caused by these compounds. Otherwise it just sits there doing nothing, which is what you want in a drug. Anyway, there are lots of different varieties of rosemary, and different levels of carnosic acid among them. There are also wild populations in the Mediterranean, as of other herbs as well, and people who make a living harvesting them from the garrigue. That can sometimes be overdone, resulting in damage to the plants, and to the environment, due to increased soil erosion when it rains. So a study from Spain just published in the journal Catena is welcome. It quantified how much harvesting of various aromatic shrubs (lavender, oregano, sage and santolina) you can do before the soil starts to suffer. The recommendation is to leave 50% of the plant biomass in the field.

Two Africas

While browsing the iafrica.com website after reading its features on the potato, I ran across an article about tea-tasting at the Mont Rochelle Hotel in Franschhoek, not far from Cape Town. Which sounds wonderful. But a poignant complement to it was provided by a post I found a little bit later on a blog from the Botswanan village of Nata, which has a line about how tea and bread are served at funerals there. Anyway, Nata Village Blog seems like it’s definitely worth following. Franschhoek and Nata are about 1,600 km apart, as the crow flies.

Kill and cure

There’s a great article at Common-Place about the Great American Ham. No, not Kevin Bacon. We’re talking how to cure “the thigh of a back leg of a hog, [with its] three large cross braided muscles, now designated the inside round, outside round, and sirloin tip.” It’s down to the “three s method: salt, saltpeter and smoke.” Sugar sometimes features as a fourth s. Fascinating historical stuff, and something of a (welcome) antidote to our incredibly popular mini-pig nibble.
