To pick, perchance to bottle
A couple of people asked me what happens when it rains during harvest. As the skies above some of the world's greatest vineyards seem to be dumping unending moisture on the fragile grapes, the questions seems particularly timely.
Water is an important part of the cycle of life. Almost nothing can live without it, and most non aquatic life will drown given too much water. In all things balance, and when it comes to harvesting grapes, less water is better.
Wet bunches of grapes tend to rot. Rot does not add pleasant flavors to wine. Even Nobel Rot (botrytis) which is responsible for the world's great dessert wines is not a good thing for dry wines.
Some grapes tend to have tighter bunches than others, and these are that much more susceptible to rot, since air can not easily get between the berries to dry them out. And air is the key. A few warm windy days following a heavy rain can save a vintage.
Even if the grapes do not rot, they may absorb the water and swell, reducing the intensity of flavors. Picking while it is raining poses a similar danger. Wet grapes add water to your wine.
If a grape swells beyond the skin's ability to contain it, it will burst. Now you have a grape that is exposed to insects and bacteria. The aphorism about bad apples is doubly true for bad grapes. You don't want these grapes in with the rest.
The best defense against the bad grapes, not only those that may have burst, but those that may have been damaged by birds or other animals, is to hand sort. This costly and time consuming procedure is exactly what it sounds like.
Imagine staring at a conveyer belt full of grapes and trying to pick out the bad ones (along with leaves and other non grape materials). Not much fun, incredibly labor intensive and for some wineries difficult or impossible to accomplish.
Even if your grapes survive the rains, the rot, the birds and the bees (ok, yellow jackets) you may have a whole new issue to deal with. Those cloudy cool days kept your grapes from ripening, and now you are faced with the prospect of leaving your grapes out even longer than you intended, just to get that little bit of extra ripening.
The longer your grapes are left out in the field the riper they get to be sure, but also the greater the risk. The later in the season it gets, the greater the chance of frost in some regions, and rain in many others.
Winemakers that find themselves staring at soggy vineyards this week are all posing the same dramatic query. To pick, or not to pick, that is the question. Whether 'tis nobler of time to suffer the slings and arrows of outrageous fortune, or to take arms against a sea of troubles, and by opposing, end them.
They may not have to chose between life and death, but for some it may be the financial equivalent. To play it safe and make a lesser quality wine, or to take a chance for better quality and profits. Ay, there's the rub.
