I have not actually checked figures, but my impression is that Musar produces more "Grand Vin" than it does lesser wine, while other producers do it the more normal way round - smaller amounts of their premium wines. Musar is also unusual in holding its wines for several years before release so they are closer to drinkablity release (I seem to be unusual, but I enjoy them a lot on release). You have to put in a lot more effort to age other Lebanese wines for yourself. Finally, taste-wise, Musar stands alone in having such high levels of VA - so high that one vintage in the 90s exceeded EU limits and they needed special dispensation to sell it. But, as other Lebanese wineries keep ther VA levels down, I am not sure the volatile style means that Musar is more typically Lebanese than other wines.
Musar is definitely not "international", mainly because it is so volatile, but I think Otto rather unfairly characterises other Lebanese wine as being international in style. Some are though - mainly in my experience some of the cheaper wines - Kefraya Les Bretèches for example. But a lot of other wines show great interest. Quite a few of the ones I have tried have been interesting in the euphemistic sense - faulty or bordering on faulty - oxidation was a common "fault", or style if you like. Others have been interesting in a positive way.
Scanning through my notes, non-Musar Lebanese wine I have enjoyed a lot are:
Massaya - Classic Rouge - of a few vintages - not a great wine, but good VFM and I have drunk many bottles - under screwcap, and tends to be reductive, so decant!
Domaine des Tourelles - Marquis des Beys - 2004 - tried last year - IIRC this is the top wine of the producer
Domaine des Tourelles - Marquis des Beys - 2003 - tried 2009
Massaya - Silver Selection - White - 2004 - tried last year, and I am going to get more of this vintage
Chateau Kefraya (the straight Chateau wine) - Rouge - 2002 - tried in 2009 and 2010
Chateau Nakad - Rouge - 2002 - tried in 2009
Heritage - Plaisir du Vin - Red - 2005 - tried in 2009 (could do with a few more years)
I write a bit about Massaya here:
