Château Calon-Ségur has produced a very serious wine in 2012. It shows just how St Estèphe’s best terroirs have actually succeeded in this vintage. The Cabernet Sauvignon, that misfired in so many other districts, was harvested here at thirteen degrees. The Merlot was pushing nearly fifteen. No greenhouses or poly-tunnels to be seen, just an extremely nifty vineyard site doing the magic [along with assiduous vineyard management]. Yes there is considerable tannin and structure in Calon-Ségur, but the tannin is clearly ripe enough and there is plenty of balancing material. There is freshness too that lends appeal.

Even in the most consistent year a Bordeaux vintage is complex. 2012 is far from a consistent year. Poor weather caused uneven flowering at the start of the growing cycle, this led to great variation in ripening, and after what eventually proved a hot and dry summer, vintage rain caused difficulties. It’s a vintage that is heterogeneous in a great many places, especially on the Left Bank. One thing is not in any doubt, however. The vintage has produced Merlot of considerable beauty and it is the quality of this variety that stuck in the mind during Primeurs week.

A week ahead of Bordeaux’s 2012 primeurs week, just what have proprietors on the Left Bank been saying about the vintage? The consensus seems to be that, despite a very tricky spring and early summer, the vintage was saved by dry and hot conditions in late July and August and some useful rain at the end of September which helped the final ripening of the grapes. Things might actually have turned out very well indeed – a vintage similar to 2000 was being touted by some at the end of September – had it not been for more considerable and progressive rain that came in mid October onwards.

2010 is a dense long-term vintage here in St Estèphe. At the best of times this appellation produces pretty full throttle wines, so the combination of a drought year with comparatively cool temperatures, certainly compared with 2009, 2005 and especially 2003, has yielded wines here in 2010 of strength – not just alcoholic strength but pretty much on every indicator of grape chemistry – but most particularly, exceptional freshness.  It’s acidity as much as anything that is the defining characteristic of this vintage. This feels particularly so in St Estèphe [and Pauillac & St Julien, more on which later]. Yes there’s formidable tannin here, though it feels generally ripe, but it’s the grip and acidity that leaves the biggest impression. This means that the opulence of the wines in St Estèphe in 2009 is replaced in 2010 by minerality, density and grip. It’s a combination that makes these wines feel pretty structured and formidable at present.
