By its attitude, this buzzard confirms the interest of plant cover for biodiversity!

It elected as hunting ground one of the plots completely covered in green fertilizer (photo), that is a plot that has just been planted, and not one of the numerous other plots that are covered every other row (to allow passage on the row simply grassy).

Jean-Baptiste, who observes this buzzard from the window of the kitchen, found that it returns every day in this same plot.

Simply because it is there that it finds most easily food to eat!

As a reminder, plant cover is an agro-ecological practice that consists of planting cereals, legumes & crucifers that, when rolled in the spring and left on the ground, bring organic matter to the soil (hence the idea of “green fertilizer” ).

Do you know that we name « eyes » the buds left on the vine when pruning?

The «eyes» I see here come rather from the holes left by old branches but the coincidence is funny!

As for the ties (these “white ribbons” attached by hand), they are pieces of cloth used after the pruning to attach the vinefoot to the wire.

Do you know why we are experimenting to create hedges on BOTH sides of this ditch?

When trimming the hedges that already crisscross the vineyard, we kept the branches to create new hedges. The branches used for cutting were cut in bevel. The other ones were recovered to cover the ground: by degrading, they will create an environment favorable to the growth of the hedge.

We begin the experiment of planting a hedge on each side of the ditch so that as they grow they form a VEGETAL ARCH that completely covers the ditch, which will have a double advantage.

First, as the ditch will be protected from light, there will be no more vegetation growing in it and we will no longer have to maintain it. Second, this canopy of hedges will create an ecosystem favorable to biodiversity.

Our little trick for successful cuttings? 

Knowing that the cutting must be pushed deep into the ground (same length in the ground as on the outside) and that the diameter of the hole must be smaller than that of the cutting (to avoid oxygen that would dry the wood), making a pre-hole is an essential operation. Some use a rebar. At Anthonic, we use an old shaker stick from a harvesting machine! Which shows that, from the pruned branches to the old material, nothing is lost !

Do you know why this vine has been hand-braided and never trimmed since its pruning last winter?

Plaiting the vine is useful as a method of prophylaxis against mildew.

Indeed, the usual operation of trimming (or cutting the branches that have become too long) has the indirect effect of stimulating the awakening of the lower buds. New branches then develop at the level of the grape clusters, causing a buildup of vegetation favorable to the moisture favorable to mildew, especially since the young leaves are more sensitive to this disease.
By plaiting the vine, making a bridge over the wire and bending it towards the ground, we cause a natural slowdown of the growth of the vine, while the new leaves will accumulate at the top of the thread and not in the sensitive area of the clusters.
Braiding is done by hand and takes an enormous amount of time, which is why we don’t do it on all our plots but where we have done it, it has helped us to limit the risk of mildew.

You often ask us what we do in the vineyard after the harvest.

Before pruning next month, we maintain the training of the vineyard.

That is to say, as suggested by the piles in the photo, that we pass through all the plots and remove the damaged posts or dead vines

We dedicate the star and excellent comment we’ve received today in a famous French wine book for Château Anthonic 2007 to all those who have helped in those difficult days.

2017 means namely for us the terrible frost that deprived us from 95% of the crop. Everything for that vintage was more complicated but the wine is excellent as showed by this star.

We dedicate this star to our faithful team, our friends and their help for the harvest and our children who helped in the vineyard during the summer even when in the same time studying with their earbuds... Many thanks to each of you! You can be proud!!
 

To get a non-chlorinated water to prepare the herb teas for the care of our vines, we made this recovery system of rainwater. 
It’s simple to understand with the picture below and the gif made by our son @picor_art . https://www.facebook.com/chateauanthonic/videos/934291520323493/

The barrel on the right recovers the 1st water falling from the roof: it’s not useful because it’s dirty from the rinsing of the roof. When this barrel is full, the ballcock raises and let pivot the gutter in the left barrel. 

We pump the water of this last barrel to prepare the herbal teas for our vines because they are more effective with non-chlorinated and not dirty water.

Today, picking & cutting of nettles to mix them with water.

After fermentation, this natural foliar fertilizer will be used to stimulate the vines’ growth because it contains nitrogen & iron. 

It’s the reason why we use it at the beginning of the growing season of the vines.

Our team is happy to announce, from the top of the big oak of Anthonic, that our wineestate is now organic certified!

We are now sowing a green cover on our soils (every two rows to let a possibility of passing) in the whole vineyard.

To cover the soils is namely one of the pillars of agroecology. Plants and cereals will contribute to enrich and aerate the soils and favor the present fauna, all measures important for a living soil.

We use a blend of a lot of organic seeds.

Plant cover is good not only for ladybirds but also for soil's life and thus for the vines !

We use several blends of plants as plant cover like faba bean (on the pic with the ladybirds) mixed with vetch and triticale (ancien wheat).

They soon will be all rolled and left in the spot between the rows. When decomposing these plants will give organic matter and nitrogen to the soils. It's the reason why they are called "green fertilizer", they constitute a natural fertilizer.

You're welcome on 6th & 7th April for the open doors at château Anthonic, the occasion to visit our vineyard in 3rd year of conversion to organic viticulture and our plantations of vines in agroforestry (with trees).

Of course, there will be also a tasting of our wines! 

Many old varieties of peach trees, apple trees and pear trees cross from now on the parcel in front of the château. 

What a symbol!

Planting today of the first trees integrating our vines (AGROFORESTRY) by the "Vignerons du Vivant", these young people becoming integrated through an "organic" training to the vines jobs.

We are reflecting on this project of agroforestry for a long time and have prepared it by leaving a space for the future trees when planting our last plots of vines. We are now so happy to see the trees (more in the next post).

    The hedges crossing our vineyards aim to create wildlife corridors connecting the wooded areas, which provide uninterrupted passageways for the fauna.

    Hedges are also refuges for birds and insects and relays for bats, all natural predators of vineyard pests.

    In autumn the hedges are besides a feast for the eyes! 

    Welcome to the bats!

    Present again in Anthonic, they constitute a natural alternative to insecticide as they are predators of some vineyard pests (eudémis and cochylis).

    The network of hedges crossing our vineyard and soon the trees planted in agroforestery aim precisely notably to create relays for the bats. They can thus 

Just to show how beautiful is the press wine of vintage 2018, a vintage completely organic produced (if not yet certified) as we were in our second year of conversion to organic viticulture.

    Interesting to notice:

    The left pile of fertilizer comes from a mushroom farm and contains therefore calcium.

    So can we hit 2 targets with 1 shot: to feed our soils before planting & to reduce the acidity of the ground when needed.

Jean-Baptiste & Philomène have prepared a heap of stones as refuge for the reptiles living in our hedges through recycling pieces of limestone from a recently planted plot of vines. 

We're now entering the 3rd year of the conversion to the organic viticulture for our whole vineyard.

This challenge isn't always easy (in particular because of the oceanic climate) but we are very happy with our choice, for example whe we see the numerous and beautiful butterflies dancing in our vines !

A space of 4,5 meters has been left free in the midden of this recently planted plot of Cabernet Sauvignon.

Next autumn we're going to plant there a row of broad-leaves trees (mostly maple trees). Later they will be short pruned in order not to compete with the vines. 

This illustrates one of the advantages of agroforestry (planting trees in the vines): to produce, with the cut branches of the trees, biomass that will be transformed in humus, for a more living soil for the vines.

     Planting of our first parcel of vines in AGROFORESTRY, i.e. with trees.

     On the picture you can see that one row is missing in the middle. In autumn we'll plant there espaliered fruit trees. 

     The aims of the association vines/trees are in particular to give the protection of the trees to the vines (through mycorrhiza and micro-climate) and to the soils (fertility).

     It's also very gainful for the biodiversity, for example to give landmarks to bats that are also predators for some pests of the vines.

In this season lots of wild orchids are flowering in the ditches surrounding our vineyard, visible sign of biodiversity.

Here are some of them.

It's not a soup but a nettles fertilizer that Philippe is preparing on the picture!

He mixes the nettles he has mowed with water. The blend is then covered to ferment protected from light. After a few days it will be filtered and used diluted with the next treatment of the vines.

The aim of the nettles fertilizer is to support the growth of the vines and stimulate the microorganisms (bacteria etc..) of the soil.

Exciting training day for our team with Marceau Bourdarias on the "green work" (crown suckering, trimming of the vines). 

These spring work prepare actually already the pruning of next winter.

Marceau explained us how to favour the sustainability of the vineyard and the quality of the crops, notably with respect of the sap flux of the vines.

    The plant cover we have sown to structure, enrich and aerate the soil in the vines and therefore make it more alive is now in flowers. There are the mustard and its beautiful yellow flowers but also the broad bean whose flowers are probably delicious because they attract and treat a lot of bees. 

    At this time Anthonic rhymes with bucolic ! 

The "plant cover" we've planted in autumn (we explained why in the precedent news) is flourishing.

One of the plants of the blend we use as plant cover is mustard that is now in this beautiful yellow blossom...

   This autumn we have sowed "plant cover", each other row to let the tractor go on working on the row with grass.

   It’s a mixing of three types of plants (cereal, leguminous and cruciferous plants) whose effects on the ground and the vines are complementary.

   The goals of this planting are: to structure the ground, to enrich it with the nitrogen fixed by the leguminous plants and with the nutrient released by the cruciferous plants and to aerate it in depth thanks to the roots of these plants.

   It’s a fact: diseases able to harm the vines do exist since the end of the 19th century. In the region of Bordeaux, the oceanic climate make the vine particularly sensitive to fungal diseases, mildew and powdery mildew, that are microscopic fungus affecting the leaves and/or the grapes.

   The vines must thus be treated; if not, there is no crop.

   The conventional option (that is not-organic) favours chemical treatments known as “systemic”, what means that they get into the sap of the plant. These products have an action on the plant for 15 days; thereafter, they must be renewed.

   The organic viticulture use only products that don’t stem from the chemical synthesis (for example the traditional “Bordeaux mixture”) and that are “contact products”, what means that they stay and protect the leaves and the grapes until they are “washed out” by an important rain.

   In the organic way, the frequency of treatments depends thus on the weather (more often, if they are more “washing out” rains) and on the stage of the growth of the vines (you should treat as long as new leaves come). If the summer is dry, it’s therefore useless to renew the protection when the growth of the vines is stabilized, that is, in general, end of July.

 After 16 years of rigorous work at château Anthonic, Jean-Bernard Despatures, our technical manager, leaves us to become one of the partners of a winery in Belgium. He made possible our conversion to organic viticulture thanks to his precise knowledge of our vines and terroir and thanks to his enthusiasm. Thank you!

 Welcome to Emmanuel Chety who succeeds him. Emmanuel is a very curious man, always wishing to learn more and to get more training, and above all he is passionate about organic viticulture, that he knows well, as he has been practicing it for more than 6 years on the 40ha winery of his family.

 His experience will be precious for Anthonic during the delicate period of the conversion to organic.

 The frost ravaged almost 100% of our vineyard. Looking forward to the resumption of the activity of the vines and, perhaps, the emergence of new buds, what can we do?

 With Albane Bervas, our adviser for the organic, we discover the “organic-attitude”. Albane explains us that the vines, after such a stress, need the benevolent and friendly hand of the human being. She recommends us to have compassion for the vines and to trust them. This BIODYNAMIC APPROACH fill us with wonder. We understand that the conversion to organic is not only a paradigm shift (from healing to prevention); it’s also a life philosophy.

 In concrete terms, we’ve to be kindly in spirit with the vines and take care of their stress and our stress with the same infusion of valerian (see the picture!).

 This year we initiate at château Anthonic sexual confusion. No obscenity but a good practice to avoid the use of insecticide against the worm of the cluster.

 Capsules scattered in the vineyard emit pheromones which cause confusion among the butterflies. Males and females of the 2 species laying on the vine are no longer able to locate them, which limits their reproduction. The bosses larvae on bunches are so limited. This avoids the driving of grains by the caterpillars and the problems of grey rot likely to settle on these wounds.

 At the end of the season the unsightly capsules are recovered.

  In fact, the conversion to organic viticulture has no impact on the usual work of the vines in winter, except that we prune them on a plowed soil. Now like before, the pruning work, with a careful respect of the structure of the vine stocks, keeps our team busy for nearly 4 months.

  The only effect of our conversion came oddly from our insurance agent, when we concluded our insurance against hail and frost. His reaction was timid and cautious. The discussion went about the potential increased risks due to the new way of growing.

  But, as always between people of good faith, we ended up finding a solution satisfactory for all.

 To help us in the fundamental change of the conversion, we appeal to Albane Bervas, a specialist in organic viticulture.

 She comes to château Anthonic each month to watch our vines.

 Thanks to her experience and her passion for organic, she makes recommendations on the aspects we should pay attention to keep our vines healthy and surrounded by a living nature (fauna and flora).

 The terroir of Château Anthonic is of clay-limestone. In these heavy soils, de-grassing was mainly necessary to enable the tractors to pass through the vineyards after rain.

 We rapidly evolved towards a natural grassing over between the rows in order to minimise herbicide use, which remained directly under the rootstocks only.

 From Autumn 2016 therefore, our organic conversion resulted in a return to fully working the soils under the vines.

 And now: action!

 Understanding the conversion to organic viticulture engages a fundamental change, which could be expressed simply as a paradigm shift from healing to prevention.

 We abandon the logic of caring for our vines when they are sick, and we enter into a dynamic where our vines naturally regain their resistance to disease.

 The conversion period is therefore critically important because it is when the vine, deprived of synthesised chemical ‘help’, must rebuild its natural defences.

 It is a change of position, somewhat like the Little Owl we found in our son Henri’s room, with its head pointing to the floor!
