Thanks Mel, keep up the good 'work'.
BRETT,
First, a dull but necessary paragraph to clear up a potential confusion. The name Dekkera is often used interchangeably with
Brettanomyces. They are actually the same genus (this is the taxonomic group just above ‘species’), with Dekkera being used for the ascospore-forming (sporogenous) form of this yeast, and
Brettanomyces used for the non-spore forming type. There are currently five recognized species of Brettanomyces/Dekkera: B. nanus, B. bruxellensis, B. custersianus and B. naardenensis, with a range of synonyms in common use. Of these, research indicates that B. bruxellensis is the most relevant to wine.
Then we looked at some wines. There were two flights of Pinot Noir, and one of Merlot. Each flight consisted of barrel samples from the same wine which Thomson and his team felt were showing signs of brett. He outlined the sorts of effects of brett on Pinot Noir as the bloom developed:
Progression of effects in Pinot Noir 1. Loss of primary fruit, particularly lifted violet and sweet cherry characters.
2. Loss of new oak characters.
3. Hints of smoke and spice appear (4-ethylguaiacol)
4. The wine begins to smell and taste medicinal (4-ethylphenol)
5. Any silky characters disappear as the wines lose flesh
6. The bones of the wine are exposed, leaving acidity and rustic, drying tannins
7. Aromas of horse and bandaid appear (4-ethylphenol)
Tasting the wines was instructive. They varied from being pretty bright and expressive to rather muted and earthy. But if I’m honest, it was only because this was a brett seminar that I was able to say with any degree of certainty that I was discerning brett in these wines: the effects at this early stage were relatively subtle. ‘These wines still have a lot to lose’, says Thomson, although he reckons that as the brett bloom develops, they will become quite unpleasant.
I can only really comment on the effect of this fungus on wines I know, and have in stock.
Vintage 2004 Cote d'Or is prone, I have one 2004 Nuits St Georges left, it was cheap ! That 2004 nsg needs food, and a couple of 2004 Beaune Teurons 1er that must be drunk soon, but they were much better wines that the NSG. I'd rather have the fruit than the farmyard, but wet dog notes are quite ok and rather interesting in moderation.
I'd like Mel to say more about the 2005 Margeaux that was brett in the mouth - but she is very busy.
As for the 2005 Lafite, I feel that this wine would have
wiped-out all others.........had the wine been drunk when it was just ready, yeah ! From at least 2014 onwards.
It seems absolutely mental to serve the 2005 1st growths of Latour and Lafite before they are ready.....More money than Sense ! 2005 is a vintage that compares with the greatest.
