Vendanges 2018 – Part 2

 

P1040186

Tuesday 4th to Thursday 6th September

After the break harvest really kicked into gear this week. One of the effects of mildew (and compounded by the hail storm later) was damage to foliage. The vine uses the foliage to ripen the grapes but also to nourish itself via photosynthesis. Damaged and desiccated leaves mean that there comes a point where the vine struggles to ripen the grapes any more and, even worse for the winemaker, things go into reverse; the vine begins to take back nutrients from the grapes in order to feed itself. This will have consequences not just this year but into the future, as the vine has struggles so much and is weak, it will not be at its best next year and further ahead.

Therefore, Jeff Coutelou has had to spend a lot of time in the vines ensuring that he knows exactly the health and condition of the vines to get the best possible grapes for this year whilst being mindful about the health of the vines. A balancing act to cause him more stress in a difficult year.

Tuesday saw some lovely Muscat being harvested from Peilhan, the grape which smells of grapes. The video below shows them being pressed and I wish I could convey the lovely fresh, grapey aromas which emerged from the press.

 

This is Muscat being made for dry wine, in 2016 for example the Muscat D’Alexandrie made a lovely orange wine which we have shared at lunch. Afterwards the pickers moved into the 2015 plantation at the top of Peilhan, the 12 rows of Morastel, Terret Noir and Riveyrenc Noir picked to blend with Syrah from Sainte Suzanne where the pickers headed next.

On a beautiful Wednesday morning the remaining Syrah was picked. Jeff decided to make a grappe entière wine so Julien and I headed into the top of the cellar to sort the grapes and send them through the chute into the tank. This had been given a dose of CO2 to encourage the fermentation of the grapes inside their skins. After a short period the skins will burst and the resulting juice will have a light, fruitiness. This process is called carbonic maceration. Sorting meant removing any leaves and other vineyard products such as spiders and snails. Mainly though we were looking for the dried grains of berries damaged by mildew and the green, unformed berries caused by millerandage.

Onto Thursday and the deployment of two teams of pickers. The Moroccan crew picked some lovely bunches of Macabeu from Peilhan before moving on to Syrah from Segrairals.

We were also joined by a number of pickers who would tackle some of the more interesting vineyards. As a result of mildew damage in Faugères some growers have little or nothing to harvest and some of their pickers came to join the Coutelou team. And we were joined by Louis who, having completed his professional baccalauréat has begun a course to help him achieve his ambition of becoming a sommelier. His stage will certainly teach him a lot about vines and wines, the numerous cépages he picked will certainly have opened his eyes to the wide world of wine.

This team picked my favourite vineyard, Rome, with its old Cinsault vines, Muscats of various kinds and all three versions of Grenache. In the afternoon the moved on to Font D’Oulette now simply referred to as Flower Power after the wine made from the numerous cépages in there. Using two teams meant that cases were returned thick and fast by Michel and Julien and I had a long, back breaking day sorting these grapes.

I have to say the juice tastes great, fruity with good acidity. Now all we need is for the yeasts to play their part and ferment that juice into good wines. The picture below shows yeasts at work in a tank where some of the skins from the pressing of last week’s Grenache. As with the grapey Muscat these bready aromas deserve to be more widely shared. Vendanges is all about the senses.

And, for Icare lovers around the world, he is taking a very keen interest in this year’s harvest.

Nature can be harsh: Part 2 – Disease

The mild weather over winter was followed in the Languedoc by a slow start to summer heat. The resulting warm, humid weather brought disease as it did in many regions of France. Mildew, oidium and couloure are all vine diseases which occur regularly and 2016 was no different but with a bigger hit than usual.

Mildew (downy mildew)

 

Sadly, humid days in the mid 20s and cool nights are exactly the conditions favoured by downy mildew, and it prospered. The humidity in the soils created ever more favourable conditions for mildew. Downy mildew lives as spores in the soils and any rain splashes them onto the vines. Mildiou is not a fungus as commonly believed, it is a one celled spore which germinates in warm, humid conditions especially between 16 and 24 Centigrade – exactly the conditions we saw in April and May of this year.

Jeff Coutelou spent many nights out on his tractor spraying the vines to try to protect them. As an organic producer (and much more) he cannot (and does not want to) use manufactured, chemical sprays. Instead he used sprays based on rainwater with seaweed, nettles, horsetail and essential oils of sweet orange and rosemary. These are better absorbed by the vines in the cool of the night.

Mildew appears as small yellow / green spots on the upper surface of the leaf which gradually turn brown and spread to leave an unsightly vine. Underneath downy white /grey spots appear, the mildew is well established by this point. It affects the grape bunches and leaves them dried out and shrivelled.

By the time harvest arrives the bunches contain a mix of healthy and diseased grapes. Severe triage is required. Bunches such as the one in the photo above will be discarded immediately. Where there are health sections though the bunches will arrive at the triage table and be sorted rigorously. Jeff reckoned that in some vineyards, especially the white vines of Peilhan, losses were up to 60% from mildew. Seriously damaging.

Here is a clear demonstration of the advantage of hand harvest (vendange manuelle), machines would simply swallow the lot and in less thorough domaines or caves the bunches will all go into the wine.

Oidium (powdery mildew)

Oidium on buds and leaf

Oidium is a related problem to mildew but slightly different. It too thrives in warm days and cold nights (so springtime is its peak period) , it too loves humidity. So, spring 2016 was ideal though oidium was less rampant than mildew. Unlike mildew it is a fungal based spore.

Conventional treatments would be chemical and even organic producers will use sulphur, a naturally occurring element. Organic producers are limited to the amounts they can use as sulphur does damage the fauna of the soils. Jeff Coutelou uses less than a quarter of the permitted amounts because he sees it as  a last resort. Instead he prefers treatments based on horsetail weed, nettles and other beneficial plants made into a tisane which can be sprayed. It may not be as all-destroying as synthetic chemicals but Jeff prefers the soils to be healthy in the long term by using these natural plant based treatments.

These photos show grape bunches hit by oidium in 2016, the powdery residue is clear though the bunches are less damaged than mildew affected ones. Nevertheless oidium is destructive and spoils wine so, again, careful work in the vineyard and cellar is needed to keep oidium out of the grape juice.

Coulure

Like most fruit plants vines grow flowers which then develop into the fruit. Vine flowers are very beautiful but also very delicate and don’t live long on the plants, a matter of a few days.

If heavy rain and wind hits the vines at this stage of their development then the flowers can be easily damaged or broken off the plant.

The result is that fruit cannot develop where there is no flower, coulure. Where flowers are damaged then berries might grow very small and seedless, this is called millerandage. Similarly berries might ripen unevenly within a bunch, green berries alongside healthy, ripe grapes.

There is nothing that the vigneron can do of course, the damage is done by the weather and no producer can successfully combat weather. Nature wins in the end. So, once again, the vendangeur and those sorting in the cellar are crucial in ensuring that only healthy fruit goes into the wine.

I cannot emphasise enough the importance of all stages of wine growing and production. From their budding through to vendanges the vines must be tended, and in the cellar observation, determination and care are needed too. To make good wine requires hard work, healthy grapes and love as Jeff has said many times.

And have a look at one of those last photos again.
