I am sorry, but there is. You are simply quoting old websites as if they are gospel, and I am telling how it really is.
So maybe we agree that the wines tasted in March are not often close to the final product?
No. Please reread what I wrote. The Left Bank wines and Pessac Leognan have all been blended. In some cases, a minor amount of press wine might be added, but that is not going to change the wine. In the Right Bank, you are tasting a very good idea of the final blend, but the wines are not blended until later.
If you were really interested, you can find the blends for barrel tastings on my site for numerous Right Bank wines. That same info is on other sites as well. Have a look at those statistics and compare them with the blends for bottled wines from the same chateau. Those blends are often the wineries website. They are also included in numerous tasting notes on Cellartracker, from people tasting at the UGC and at the chateau or various dinners.
… You are never going to have a level playing field. For example let’s say you want to taste Pauillac. It is impossible to have all the wines from the appellation available to compare, as several estates do not provide samples for tasting outside their chateau…
It used to be the case, but then the high end chateaux decided they did not want to do it anymore in fear of being hurt by blind tasting.
No, that is completely wrong. Where are you reading this? Several estates have NEVER sent barrel samples for tastings. You can include all the First Growths, some Second Growths, Petrus, Le Pin, Lafleur, La Mission, Yquem, Cheval, Ausone, Tertre Roteboeuf, Leoville Las Cases and others.
…Some wines are always great in barrel, but they don’t develop the nuances as expected by the time the wine is bottled, or a few years later they lose their charm)…
So maybe we agree that the wines tasted in March are not often close to the final product?
No. Please read the entire paragraph. You need an understanding of how each wine ages, which is gained after years of tasting in barrel, and watching them over years. It has nothing to do with how the sample was prepared.
At the end, En primeur is an OK proxy of the final quality of the wine in general and it is a great marketing machine. It has turned into a marketing only machine for the high price bordeaux as they do not play the primeur game fair.
Again you wrong. En primeur is the greatest marketing machine in the history of wine. True. But it benefits consumers, the trade and the wineries.
Consumers because it would be impossible to have that much wine, from so many estates offered all over the world for what is truly a small markup. Plus stacks of journalists and members of the trade are on equal footing to taste the wines and report their opinions, offering a myriad of views.
The trade because they can taste 1,000 different wines over a few a few days and are more than able to rely on their palate for buying decisions.
The wineries, because those that are strong enough to sell as futures have access to cash flow. The system is not just for high priced wineries. Several hundred wines are offered as futures. Most are not expensive.
If you are curious and want a better understanding on how the system was formed and how it actually works, spend a few moments and read this article. Learn about Negociants, Courtiers, Buying Bordeaux En Primeur
Honest, I am trying to help you understand how it really works. It does not matter if you like the system or not, the wines or not, futures or not. But you should at least have a better idea of what really takes place.
