As I ramble on a bit below, here's the broad plan for this Open Mike
Weekend 29th / 30th March: 1999 Chateau Musar (red)
Weekend 5th / 6th April: 2000 Chateau Musar (red)
Background: I'm somewhat reticent about this, as resident Musarite Otto could probably write a book about this winery and their wines. However by way of (not so) brief summary...
Not the oldest winery in Lebanon (Ch. Ksara in 1857 holds that honour), but very much the most famous. In some respects the fame is for the 'wrong' reason of their persistence in making wine throughout the civil war (and indeed the more recent troubles), just missing two vintages in the process (1976 and 1984). IIRC one of these vintages (1984?) still sits in barrel or bottle, waiting to see if it emerges into a wine that is appropriate to release.
Musar was founded in the 1930's by Gaston Hochar, who having trained in Bordeaux, aspired to producing great wine in the Bekaa Valley. The cepage of the wine varies by vintage and whilst Cabernet Sauvignon is a key part of the mix, also included are the 'lesser' grapes Cinsault and Carignan, plus Syrah/Shiraz, Merlot and Mourvedre. There may be other grape varieties. Vines are (so I'm told) dry grown at 3,000 ft altitude.
So is this a Bordeaux look-alike? Not really. In some vintages it's closer to the Rhone; in others more Burgundian, in others maybe Bordeaux is a closer fit. There is always IMO a streak of 'Musar' running through it's core, that sets it out on it's own as a very unique wine, despite what are often relatively significant vintage variations. What makes it unique is rather difficult for me to attempt an explanation, but I will give at least my own take on it.
Musar is a wine that is a little 'on the edge'. It's commonly accepted amongst it's fans, that it regularly displays high levels of Volatile Acidity (VA), giving a lifted, verging on vinegary aroma. Suggestions of other winemaking faults have often been levelled at it, though frequently it's a wine quoted as an argument against spotlessly clean wines. It has character in Spades.
Consequently Musar is a bit of a love it or hate it wine. In recent times I've seen it twice in tastings with wine newbies attending. In both instances it's been a wine that's drawn more than a few 'wow's from these people. I went through the same experience years ago and it has the ability to both be memorable, but also to highlight that there's a bit more to wine than initially meets the eye.
Musar is typically released with significant age - the UK is currently on 2000 vintage, though 2001 must be approaching soon. For an insight into what it tastes like pre-release, Broadbent's Vintage wine book includes brief notes on the unblended constituents of the wine. Tasting it young & blind, you might doubt it would age that well, but it's not built like most other wines and age well it does. Old vintages sell at a significant premium to the current release and appear to be drip-fed into the market by an established distribution network.
ServingThere is a firm body of opinion that Musar needs extensive time in a decanter (c. 4 hours) to shine at it's best. I'm undecided, but may take this chance to test the theory (by tasting on opening, then decanting a few hours ahead of drinking the remainder). I've no great view on food matches, but would probably choose game if I had to - anything from Guinea-Fowl, through Duck, to Pigeon or Pheasant. Lamb should also be a good match and it holds up well to mildly spicy dishes.
Extracts of Harvest reports from Musar's own website
1999 was an exceptional year. Starting with a mild winter with very little rainfall, it was followed by our normal spring weather, which allowed a good flowering. However the yield seemed lower than usual due to the lack of water. The summer was mild and although July and August were cloudy, September was hot and sunny. This enabled the grapes to reach maximum maturity with great all round concentration – good acidity and a high sugar level.
2000 A very natural winter and spring. There was average rainfall in winter with some cold days, followed by nice weather which allowed flowering to develop quite well in the spring. However things started to deviate from the norm with the arrival of summer. July was unusually hot with some very dry days - the temperature even above 35 degrees centigrade. This was followed by an August which was hotter than average but it wasn't as hot as it was in July. Happily enough September was back to normal!
We started harvesting on the 6th September, one week earlier than usual. The crop was healthy and very good but the quantity was down by 15%. The grapes of this year were sweet but tannic with good acidity. Fermentation progressed well - slowly with very little heat as it was naturally under control. Interestingly the level of alcohol was higher than usual - almost the same as 1999. All in all, it was an easy harvest and an easy fermentation with hardly any problems and malolactic fermentation followed its normal course.
Other sources
Many. However as well as Musar's own site http://www.chateaumusar.com.lb/english/cave1.aspx?id=1 (where you'll see a picture of the label), Jamie Goode's Wine Anorak site has a good write up of Musar and also his notes from 'Musarathon', an extensive vertical tasting of the wines organised through a UK wine forum.
For anything else (and corrections to any errors/omissions above) I'll point you towards Otto, who will I'm sure have better answers than me.
For newcomers to Open Mike (and those, who are still awake after my ramblings), it's an opportunity to taste the same (or at least very similar) wines and compare notes and discuss not just the wine, but our own different perceptions of the wine. It's ideal for a specific weekend, but feel free to drift into the following week, or even later. This Open Mike is a variant, in that we'll attempt to cover two vintages (1999 and 2000) over consecutive weekends. Don't worry if you can't make the specific weekend, we all have lives outside the board (we do don't we?

So to confirm
Weekend 29th / 30th March: 1999 Chateau Musar (red)
Weekend 5th / 6th April: 2000 Chateau Musar (red)
Looking forward to hearing all your views
