My daughter Jackie having fun harvesting last year at Domaine du Banneret
Dear wine lovers,
Here we go for another season of "vendanges*" in France. Beaujolais usually starts first at the end of August in producing the famous "Beaujolais Nouveau" with the light Gamay grape and they should be over in December with the ice wine (yes, there is a very little French production in Alsace).
Some of you have told me about your dream of going harvesting some day and some are actually about to fly to France for that. Today, here are a few things you might want to know when you go harvesting.
At this point, all the talks I hear from vineyards announce high sugar contents and issues with natural acidity. We had another very dry summer and maturity is in moving along. In any case, until the grapes are in the tank, any prediction is pure fantasy.
In fact, you should know that 90% of the quality is already determined when the grapes are harvested. The rest is techniques to try to enhance this quality or not to deteriorate it. For that, the most important is to harvest at the right time. And this is a real challenge because when the grapes are about to be 100% ready, there might be rain which might then spoil the quality by diluting flavors, delaying the picking date which will alter sugar and acidity content and maybe ruin the quality in itself with rotten grapes.
This weather interaction is even more problematical since, at about harvest time, the two major components of berries, which are acidity and sugar, evolve very rapidly (Download acidity_sugar.jpg - a very rough graph to show you how sugar and acidity evolve in time).
The problem is that there are rotten grapes that have this famous noble rot and these are great. When you don't know, a tip is to smell the grape. If it smells vinegar, just drop it to the ground. If it has a smell of currant raisins, you are more welcome to keep it.
So when the time has come in being in the vines cutting. Sorting out the bad grape is very important, during the cutting as well as they reach the sorting table in the cellars. They are then destemed or not (depending on the level of tannins looked for) and put in the tank after a little crushing** which will release the juice from the skin. See the picture and a very short video that will show two very traditional way to crush grapes (Download Foulage.jpg and Download foulage_in_corsica.wmv)
Of course, what I am telling you concerns the old.fashioned way to harvest in France. But it is always a memorable time and we all are now looking for the next to come. I will tell you all about this in a few weeks...if mother nature allows us to have fun !
Cheers,
