Tour de Segur is one of the secondary (perhaps tertiary) chateaux of Pierre Lurton and the wine most often appears in French supermarkets and at discount shops where it is a good seller at its price (about 6 Euros today). My tasting note for the 2001 wine follows.
As to pretentions, have no fear, as Tour de Segur was purchased by Alexandre de Segur about three years before he purchased Chateau Latour. Neither, of course, remains in the hands of the de Segur family today.
Chateau Tour de Segur, Lussac-St Emiion, 2001: Good for this producer, showing medium- to full-bodied, with soft tannins integrating nicely with traditional current, berry and black cherry fruits. Nothing complex here but a pleasant, lightly spicy and moderately-long wine at its best with small cuts of beef, veal or lamb. A blend of Merlot, Cabernet Franc and Cabernet Sauvignon (60%, 25% and 15% respectively. Drink now-2011. Score 88. (Tasted 13 Apr 2004)
