When driving through certain parts of Mallorca in November and December, one will pass by many a vineyard in a state of colourful display – yellows, oranges and reds. These vineyards were full of activity during the months of August and September when the grape harvest was taking place. Now at the beginning of winter, the vine fields appear quiet and sturdy, tranquil, and often quite dead and without any active life whatsoever.
But invisible to us, there is more activity than meets our eyes. Yes, the Vitis vinifera vine plant has slowed down its business of fruit production but now it is producing a substantial amount of Ethylene (H2C=CH2), an organic compound which is needed for the process of abscission (the shedding of its leaves). At the same time, the vine plant is also producing Abscisic acid (ABA), a plant hormone which is needed to enter into the dormant state – the period of hibernation – during the winter months. ABA prevents cells from dividing and suspends growth.
The vine plant is very intelligent in as much as it knows exactly how to regulate its metabolism, its energy consumption and its growth. By stalling growth during the winter a lot of energy is saved. This process is similar to an animal’s hibernation. Most animals who hibernate store food as fat and then use it to run their essential systems during the winter, rather than grow any more. Likewise, the vine’s metabolism slows down during dormancy, and this is partly why cell growth is impeded. Since the plant has to conserve the energy it has stored, it is best if it uses the energy up slowly and only for essential functions.
We at Son Alegre think it is best not to interfere in this energetic process of shedding and absorption. In fact, we interfere in our vineyard as little as possible throughout the year. We have our unsung hero helpers such as ants and worms, ladybirds and bees, spiders and snails, who help us day in, day out, with the aeration of our soil and the distribution of plant nutrition, macronutrients, micronutrients and moisture. Without these helpers we simply couldn’t do our business; without them there would be no Son Alegre wine.
Let’s not forget what Nature does, every second of the day, all year round. Thank you.
And let’s not forget to say Thank you to John Hinde, the photographer of the photos of today’s blog entry and, in fact, of most of the photos published on this blog throughout the year.
Thank you, John. Thank you Nature. Muchas gracias.
