Alsace Vintage 2007 - This vintage has a very interesting climatic profile, and has shaped surprising and varied styles of wines.
Budburst started very early at the end of March in most regions. By mid-April, all vineyards had small green leaves and were about 2-3 weeks ahead. April and May were very hot and dry, causing exceptionally early flowering, similar to 2003. Flowering proceeded quickly, producing large, even clusters. In June, July and especially August, hot periods alternate with cooler and more humid days. In mid-July, the harvest was scheduled for the end of August, but, gradually, as the grapes took longer to ripen in cooler August conditions, the start of the harvest was pushed back to early September.
Constant humidity and heavy rainfall created difficult working conditions in the vineyards throughout the summer. It was a challenge to be able to use each dry period to spray the vines. Biodynamic preparations and herbal decoctions helped us not to increase the amount of spraying products and their frequency. Sure, there was a little mold on the young top leaves, but nothing that would interfere with the quality. By the end of August, the weather became much drier and warmer, allowing the grapes to reach good concentration while maintaining fierce acidity and excellent health.
We started the harvest on our estate in Zind-humbrecht very early on September 7 and the dry climate allowed us to spread the harvest until mid-October, in order to take advantage of the potential of this extraordinary vintage. Noble rot began to spread on the grapes towards the end of September, particularly on Pinot Gris and Gewurztraminer.
In 2007, the grapes were allowed a very long growing season without heat or draft stress in summer, and enjoyed cool, sunny days in September/October. How much better can it be? The grapes remained healthy, packed with high acidity levels, ripening slowly, developing complex aromatics. Yes, 2007 is a great vintage!
More than any other vintage, it was important to adapt to the specific climatic conditions. The vines were plowed early, to avoid too much competition with the growing grass during the dry periods of April and May, but with the rainfall becoming increasingly heavy, we allowed the grass to grow in the vineyards, so that we could enter the vineyards in all weathers. Investments in previous years in smaller, lighter tracked tractors were very useful in 2007. They do not create compaction and we can enter the vineyards even if the soils are very slippery and fragile. The fight against diseases (especially late blight) was crucial. This fungus grows at night, with 100% humidity and above a certain temperature. All of these conditions were met almost every day in the summer of 2007. Problems arose when there was a break in the spraying cadence, due to the fact that sometimes this involved working weekends, early or late in the day and sometimes when heavier machines could not get into the vineyards after heavy rain. In organic/biodynamic cultivation, we use highly diluted Bordeaux mixture (copper sulfate). As we do not want to spray too much copper, it is often mixed with other decoctions or plant preparations in order to make the vines more resistant and able to defend themselves. However, using only a light dosage, we sometimes had to spray as often as weekly!
The fact that the grapes remained healthy with high acidity allowed us to produce very dry wines in 2007, particularly for the Riesling wines. Anything harvested around mid-September has usually been found to be fermenting very dry or almost very dry (less than 5 g/l RS). We had almost considered labeling certain wines with an index 0 (generally it goes from 1 to 5, 1 being the driest). The harvest is slightly larger than usual, but due to the exceptional quality we won't complain. Our AOC Alsace wines reached an average of 47hl/ha, and our Grand Cru 31hl/ha.
