So for those who don’t know, this wine is a collaboration between one of the most famous California winemakers and one of the most famous Bordeaux wine makers (the grapes are from Napa). 
The young expression when I first had it 10 years ago was big bold ripe fruit, probably the quintessential Napa cab. 
The aged expression had more secondary and tertiary characteristics, terroir, and represented Baron Rothschild in respects of crafting a wine that could grow and develop and express the care that goes into winemaking as opposed to simply growing good fruit. 
The young version of it perfectly expresses Mondavi and Napa. The aged version captures the elegance of Bordeaux winemaking and Rothschild’s fingerprints. You cannot fully experience this wine unless you’ve had it young and old. Unbelievable experience tonight.  — 2 months ago
Good for a restaurant wine choice when there are no Italian reds. Not overly juicy or in your face typical of the region. Probably due to the nice peppery overlay. Acidity and tannins well balanced to permit mouthwatering enjoyment up front followed by a long relatively soft finish. Priced a bit much. — 3 months ago
From 375ml. 
A very good Rhone producer visited in 2015. 
At pop & pour, the fruits almost had a mid berry bubble gum character. That toned down almost immediately. Fruits are ripe; blackberries, black raspberries, baked plums, raspberries, dark cherries, juicy strawberries, chocolate bar to fudge, grilled, smoked meats, black pepper, dark spice, nutmeg, clove, iron pan, black tea, a touch of rubber toy, slight tarriness, dry herbs, roasted chestnuts, tobacco leaf, dry crushed rocks, dry top soil, hints of mint, dark, red flowers, violet’s, nice acidity with a well balanced-structured, stiffly tensioned with a lush finish that lasts 90 seconds and lands on earthiness & spice. 
Plenty of life left in this 2012, even in 375ml.  — 3 months ago

We had the 2012 Vintage on 7/12-13/25. With 13 Years of aging, all the tannins have been smoothed out. Tastes of blueberry, plum, leather and spice. Medium to full bodied. Still fruit forward. Very good — 3 months ago

Unbelievable. So much flavor, so light yet good texture and long finish. Probably my favorite. — 6 months ago
A good wine. Oak, a bit of chocolate, dark fruit and cherry. Pretty dry but smooth enough that easy to drink. — a month ago
Pretty deep ruby , thin ruby rim . This is quite closed at first , but very focused mineral and grafite , oyster shell notes with dark blackcurrant and blackberry notes , spicy touches too . On the palate this is really focused and reserved , lots of mineral tinged black fruits , tobacco , oyster shell . Quite rich yet very good balance, fresh acidity . Ripe but gritty tannins , saline and really long finish . Accessible now , but really destined for the long term. Wait another 5-10 years , will drink well a further 20 .

No formal notes . Quite deep ruby , garnet , thin garnet rim . This is quite open and aromatic , with a spicy , herbaceous cassis , truffle , tobacco , grafite hints , very classic and serious but also really attention grabbing . On the palate this is quite rounded and juicy for Las Cases , good mineral , grafite tinged cassis , quite fine but present tannins , balanced acidity with a tobacco tinged finished and pretty good length . Drinking well now but also can go a while yet, perhaps over the next 10 or so years . — 3 months ago
Medium ruby garnet quite narrow terracotta rim . Quite herbal , dried strawberry and red cherry nose , touch of iodine , sous bois , dried mushroom notes , discreet roasted coffee note after a while. Quite pretty red fruits on the palate with good freshness , strawberry , earthy cherry and a marine , iodine like note , sous bois underneath . Quite elegant and well balanced acidity with fine tannic grip . Good red fruit , earthy tinged finish . This is showing more advanced than the 2001 Reserva , and would like to try another bottle of this , as I suspect this half is a bit below par. On the basis of this bottle drink now and over the next 5 or so years . — 4 months ago
From mag. soft raspberry fruit. Slightly tart. Very good purity. A little light compared to the wines alongside — 6 months ago
It has a nearly opaque, dark fruited appearance that opens up to very appealing and persistent aromatics and flavors of blueberries and blackberries.  
There is still a good amount of primary fruit; it is medium/full, well structured with a good balance of juicy acidity and refined tannins at the finish.  New oak is there, but unobtrusive. 
Overall, this 2010  is a reserved and savory St. Julien that doesn’t whack me over the head with gobs of oak and loads of sweet jammy fruit.  It is definitely “worth a search” if you don’t have it.  — 8 months ago

Medium deep ruby , quite thin garnet ruby rim . Cassis , blueberry , blackberry , iris , pain grillé. On the palate this is quite dense and rounded , with more dark fruits , cassis , blackberry and a savoury , saline seaweed tinge on the finish . Fine but noticable , sweet tannins , and fresh acidity , quite rounded and richly fruited but very balanced . Good length with grafite , mineral and creme de cassis . Polished and quite decadent but all elements very balanced . Just drinkable now with time in decanter , really fruit driven still, but will improve well over the next 10 or more years and last well a further 10-15 . This shows some of the ripeness and exuberance of 2009 paired with the flamboyance of Mouton , makes for quite a pairing a very promising future ahead. — a month ago
