We have been busy at the Winery over the last few weeks blending base wines from the 2019 harvest. Although it was a difficult year in terms of weather (summer, where were you?), we are very pleased with the quality of the wines produced.
When creating blends, we often use the analogy of the painter, the canvas, the tubes of paint and the palette. It is true to some extent: we have a choice of many different varieties, clones and tanks to play with. But unlike the painter who will mix blue and yellow and always create a green colour, blending wines can prove a bit unpredictable.
After what seems like years in the making, we are very excited as our new building, Phase 2 now called Bottling, has been filled with brand new shiny equipment.
We are getting ready for harvest: all winemaking supplies are in and we have started to go through a thorough cleaning of the winery as we do every year.
At the same time, what we used to call the “on-lees storage”, the part of the winery that was dedicated to storing the ageing bottles from previous vintages, has been removed. The temporary walls have been taken down so now the whole ground floor of the winery is again one large open space. We also need to remove the very large AC unit, which used to cool down that space.
We just bottled our 2016 sparkling wines, around 43,000 bottles and 3,200 magnums. Until this year we had been bottling at 2,500 bottles per hour, which worked fine for smaller production. We are now starting to get volumes of wine that require higher speed for bottling and this is the kind of equipment we have been looking at for when the time comes to purchase.
After unexpected delays, as our bottle supplier ran out of bottles, we’re finally getting ready to cold stabilize our wines prior to bottling in July. This year, we decided to ask a contractor from France to come with an electro-dialysis unit. We wanted to see how it works and familiarize ourselves with it before we actually purchase one, hopefully in early 2018, so we can treat the 2017 wines prior to bottling.
2017 is not going so well for many producers. If you read Cameron’s last blog you‘ll have heard that severe frost affected many parts of France, such as the Languedoc, Bordeaux, Chablis, Jura and Champagne regions. Losses are up to 90% of the harvest to come, which is obviously heartbreaking. England was not spared and some producers suffered significant damage too. It reminded me of the role of reserve wines.
The quality of last year’s harvest was fantastic: A perfect balance of flavours, sugar levels and acidity. The wines were a bit “difficult” to work with, for example, the malolactic fermentation has taken longer than usual. However, at last it has now been completed through all the lots, and whilst we get the wines ready for bottling by fining and stabilising the wines, we have also started to work on the blends. It’s a very exciting moment in the year of a winemaker.
The majority of must/juice from our recent harvest has completed alcoholic fermentation. Now, we wait for our malolactic bacteria culture to be ready, so that we may use it to inoculate all the tanks so that they undergo malolactic fermentation, to soften the acids, which we expect to be completed early in the New Year.
We are often asked why we use commercial yeast rather than just letting indigenous (or native) yeasts naturally do the work. There are various reasons why we use commercial yeast.
Given our increasing crop yields, our four-tonne Coquard grape press was not sufficient to cope with the upcoming harvest, so we ordered a new eight-tonne press to give us sufficient capacity to allow us to process more fruit in a day. In previous harvests, our picking window has been less than two weeks, so with increasing yields over the next few years we’ll continue to grow and add new presses until we have a total of four eight-tonne presses.
The wines from our 2015 harvest have completed their second fermentation in bottle, and we have been put to rest in the cellar for a few years, until the wines develop the fantastic flavours from the yeasts autolysis (fresh bread, brioche, nutty).
Every year the French winemakers organise the Vinalies, which is a professional national tasting that assesses both French and foreign wines. The first rounds of the tasting have each region of France tasting its own products for a pre-selection. Once that selection is done, the final tasting will occur when all winemakers are gathered again, in April, when the pre-selected wines are tasted and rated to pick our favorites, give awards and finally publish a guide.
A recent article in Decanter discussed whether or not to disclose and/or display disgorgement dates on bottles of sparkling wines. I was horrified to read that a Champagne producer thinks “that the recent obsession with disgorgement dates is reducing the winemaking process in Champagne to insignificant numbers which are not understood by most of the people talking about them”. What a way to think about your customers!
As yet another harvest has come to an end, I sit down and reflect on how things went this year, looking for ways to improve the way we process fruit. So far the only thing that I wished had gone better is… the weather! We had poor summer but a great autumn. I think capricious weather, especially here, will always be the challenge of winemakers and viticulturists (Cameron, there is no way you disagree with this!?).
Wednesday, 17th June was a very exciting day at Rathfinny Estate as we bottled roughly 5,600 bottles of our first sparkling wine! We’re not bottling one million bottles a year yet, but that will come faster than we think.
The base wine already had about 11% v/v alcohol, and we added sugar for the second fermentation, which will increase alcohol by 1,5% v/v. A critical factor for this bottling was the preparation of a good yeast culture.
