Bordeaux facing 40˚C

This post is also published on JancisRobinson.com and Liv-ex.

Come at the end of June’, I said to my mother when we arranged for her to stay, a while back. ’The weather should be nice then.’ It has indeed been hot and sunny but we certainly weren’t predicting that the temperature could reach 40°C this afternoon. We – and the vines – are bracing ourselves for a heatwave over the next week, with the odd storm mixed in for good measure.

You can identify Bordeaux because it’s the one marked 40˚C. In June…

The prospects for the vintage, heatwave notwithstanding, are bright. Bordeaux had close to ideal conditions for the rapid flowering in late May and early June, which was crucial for the size and evenness of the crop; then rain after the 9 June was helpful for the thirsty vines. Since the huge trade fair Vinepxo in the middle of the month, it has been dry and hot again.

Summer schedules for vineyard staff have kicked in, and many seasonal workers sensibly prefer to start the day at 6am to avoid a scorching shift in the vineyard after lunch.

It’s also the time of year when many chateaux strip away the leaves from shading the bunches on the ‘morning sun’ side of each row of vines, to aid the ripening process. The two pictures show Merlot in Pauillac, with leaves intact and leaves removed. The leaves are usually removed on the ‘afternoon side’ much later in the season, once the heat of summer has passed.

Some even do effeuillage on both sides of the rows now, exposing the pea-sized grapes to what will undoubtedly be brutal heat. I know several managers who believe that early exposure to the sun helps the grapes in the long run, although I’m not entirely convinced – I mean, 40°C? (Personally, I’ve postponed any leaf plucking for now.)

New plantations of baby vines also have to be watched. Most new vineyards – usually ones replacing older vines rather than new sites – are planted surprisingly late in the Spring or even later, as a matter of course. Irrigation is only permitted for young vines which are not in production as yet, and usually undertaken by a team manning a huge container with water lances or hoses (as at Ch Léoville Barton, pictured below).

Temporary watering system for young vines (that are not in production) at Ch Pavie, St-Emilion, June 2015.

There are alternatives – at Chateau Pavie in Saint-Emilion they have installed a temporary watering system for the young vines in front of the chateau (pictured), while another famous estate is using individual roof tiles to protect each baby vine that they planted in June.

Installing anti-hail netting at Ch Bauduc, June 2015.

After such heat, there’s always the risk of summer storms. Some rain wouldn’t go amiss – just don’t mention the G-word (grêle). We don’t really want our experimental anti-hail nets to be put to the test. They are, after all, only a test.

    Seeing the high temperatures made me wonder instantly about the storm risk. Interesting therefore to see the experimental netting. I had wondered whether some such possibility existed. Hope it proves unnecessary, but otherwise does the job.

    Thanks for the update – with all good wishes for the forthcoming vendange
    And freedom from hail.
    Do hope to visit you perhaps next year
    hope we can sort out the customs duty to Jersey in new year
