When one of the members of my monthly blind tasting lunch crew asked me if he could bring all of the wine for one of the lunches, but declined to say what they would be, I had faith that they would be interesting. I found out yesterday just how interesting.
The Robert Mondavi Winery has always been interested in the technical aspects of winemaking and in how to improve their techniques. As part of these efforts, they would submit the same wine to various different treatments to see what they liked the best, and in some cases would bottle some sample sets so that the tasting of the experimental wines could be taken on the road. As far as I know, they never sold any of these sets.
I was a fascinated attendee at such an event in Vancouver in 1983, at which time I had been seriously interested in wine for perhaps 4 or 5 years, and was in the early stages of assembling a cellar, attending all the tastings I could find and taking detailed notes on what I was tasting.
The tasting in question was a series of 7 bottles of 1978 Mondavi Cabernet Reserve, all with different oak treatment. The current sales manager, who attended our lunch, advised that they continue to do this today, currently using Chardonnay. He declined to answer my jibes about whether the unoaked or lightly oaked Chard was better than the commercial product which often seems to have been stirred with an oak plank.
It may surprise some people that the winery were that serious about investigating oak, given their current use of it as an emblem for 'quality wine' in their advertising campaigns, right down to touting "Woodbridge - it's got oak!". I suspect that the only reason we don't see promotional T shirts with "I've Got A Woodie" slogans is the continued august presence of Robert Mondavi himself.
In any case, at the end of that historic tasting, the sales agent in BC, who also attended our lunch, had an extra set of bottles left and gave them to the member of my group, who put them away in his cellar, and brought them out 20 years later for a follow-up tasting. I wish that I could find my notes from so long ago, but I'll have to rely on memory.
The wines we tasted are set out below. All were taken from the final blend that vintage, which was 3% merlot, 5% cab franc and 92% cab sauvignon. The alcohol was 13.5%
- Old American oak from 1975
- New American Oak from 1979
- 1979 New Limousin Oak from Francois Freres, fire only, heavy toast.
- 1979 New Troncais Oak from Francois Freres, fire only, heavy toast.
- 1974 Old Nevers Oak, fire only, normal toast
- 1979 New Nevers Oak (Demptos), fire only, light toast
- The actual commercial Reserve release, which used 87% new Demptos medium toast and 13% old Demptos medium toast.
The American oak was not fired or charred; the staves were just bent with steam, which results in a rawer oak taste, while the French oak is toasted/charred over a fire in the traditional manner, which imparts a more complex result. It is difficult to say that one is absolutely better than the other, for while there are many rather raw examples using American oak, and even the Aussies are switching to French, some wineries, notably Beaulieu with their Georges de Latour cab, produce excellent wines using American oak.
Results were as follows:
- Very mellow nose (the opposite of my recollection of this as a young wine), sweet in the mouth and still showing surprising tannins, though soft now.
- More oak in the nose, and it seemed a bit sweeter in the mouth.
- Perhaps my favourite of all of them - less vanilla, not as sweet, but more complex and elegant - hard to believe they are the same wines!
- More tannins (interesting, that), and the tannins are drier, and they overpower the fruit in the wine.
- Light, elegant wine, but without the complexity and flavour interest of number 3. Second favourite for me.
- Very good, toasty and smooth, but a tad aggressive, and not as harmonious as 3 and 5.
- This bottle was slightly corky and losing the fruit a bit, so we opened another bottle, intended to go with another flight with the meal, to see if it would show differently. Indeed it did, and showed markedly better fruit - a much better wine over all.
We then cleansed our palates with a magnum of 1990 Pol Roger Brut, which by the way is now showing much better and fresher in large format than in single bottle size.
We finished up with a fascinating mini-tasting:
1974 Cabernet (regular bottling) - this was made by Zelma Long, before Tim Mondavi took over responsibility for winemaking. It was also very slightly corked, but not to the same degree as the 78 Reserve had been, and I don't think it affected the other aspects of the wine. In fact this one was amazingly alive, although fading a bit and now a tad acidic in the finish and definitely losing fruit.1974 Reserve - the wine of the day, as far as I am concerned! 13% merlot (the highest to that date in any reserve), and the nose disclosed a typical anise and mintiness that was lacking in any of the 78s. The wine exploded on the palate with complex flavours and was soft and very long. Excellent!
1991 Reserve - added as contrast to the early wines - Tim believes this to be the best they have made to date, which is saying a lot, as the 94 is pretty impressive! Sweet dark fruit, great length, excellent structure, but in the end I have to opt for the 74.We discussed these two wines and the major difference in technique is that while they used to harvest good ripe fruit in good vintages, their canopy pruning technique was not such that the tannins would be quite as ripe - the leaves were left on to a greater degree and even though the residual sugar and extract levels could be equivalent, the tannins in the old wines would be harder, greener and not as harmonious in the wine itself. It is Tim's theory that the tannins are equivalent other than that aspect, and the new style should age as well while showing better in youth. Personally, I doubt that the
91 will ever be as interesting as the 74, but I'm game to see in another 17 years........This was one of the most interesting and instructive tastings I've done this year.
