Aug 30th was a Sunday so no picking but Jeff was still in the cellar working. The early wines needed to be checked and moved as necessary.
Monday 31st dawned cloudy again and it was time to tackle the biggest of the vineyards at Mas Coutelou, Segrairals. The Syrah was ready to be picked and Jeff had decided to use carbonic maceration to ferment the grapes which are probably not of the same top quality as those from La Garrigue or Sainte Suzanne which were picked last week.
Grapes which are pressed like those described last week ferment in tank as yeasts react with the juice to change the sugar to ethanol, ie alcohol. The yeasts are natural from the skins of the grapes and the atmosphere of the cellar. In the case of Mas Coutelou and many artisanal winemakers this is the case though other winemakers will buy yeasts some of which are designed to add particular flavours to the wine. None of that in Puimisson, these are natural wines.
Carbonic maceration means that the whole bunches go into the tanks, grapes and stalks alike. The tank is filled with carbon dioxide which permeates the grape skins and starts the fermentation within the cells of the berry. Some of the berries at the bottom of the tank will be crushed by the weight of the grapes and so there will be some conventional fermentation too.
All the grapes are given a light crushing later by which time ethanol will have formed inside the skins and so the resultant juice is ready made wine. The result is often more fruity and juicy wine.
To achieve this the tanks are filled from above so we worked in the space above the cement tank with the grapes arriving at the back door which is a level higher than the front door. The space is smaller and the heat from the grapes was high. It was hard work, believe me. Sorting still had to be done before the grapes could go into the tank, quality comes first.
And after 9 hours of back breaking lifting, carrying and sifting it was, as ever, time to clean everything from top of the cellar to bottom as we see here with Jeff and Michel.
The night of the 31st brought a big storm with lots of rain, not the ideal conditions for harvest at all. Rain can cause rot and problems. However, it could have been much worse as news arrived of huge damage caused by hail in the Chablis region. For all the forecasts of how the harvest might turn out it is only when the grapes are safely in the tank that a vigneron can be assured of the quality of wine they might make. Commiserations to the Chablis producers.
September 1st was a quiet day as the rains from the storms meant the grapes were too wet to harvest. In the cellar more checking and remontage, the process of pumping the wine over the cap of skins and must. Further analysis of the wines showed that the yeasts are acting quickly and the fermentation is progressing very well.
Today, September 2nd, the remaining white grapes, Grenache Blanc, from La Garrigue. Then on to Peilhan to gather some of the white grapes there, Maccabeu, Grenache Gris, Carignan blanc and Clairette Musquée.
The core team of Jeff, Carole, Michel, Cameron and myself were joined by Matthieu who has worked the harvest before here. There were some lovely bunches though the wet weather has caused some rot inside some of them, Careful sorting took place in the vineyard to take only the best grapes which tasted really sweet and juicy, the Clairette was especially tasty.
The white grapes were taken back to the cellar and placed in tank after being destemmed. It is possible that Jeff will make his first orange wine with them. An orange wine is a white wine made like a red wine, ir the wine is fermented on the skins thus extracting more colour, texture and flavour from them and giving the wine an orange tint. However, analysis and the next few days will be needed before the final decision is made.
In the afternoon, Matthieu, Jeff and myself did more remontage of the Syrah grapes harvested in the last week, which is already tasting well, with very healthy technical analysis and beautiful aromas. And, then, as ever, the cleaning.
