法國紅酒係哪1級 and how much 呢?

1. Pls. double check the spelling if it is Clement Dieux Caperot or Clement Vieux Caperot. But for sure it is neither from the Grand Cru nor Premier Grand Cru of the Saint-Emilion 2006 Classifications. And it is not from the 1st growth.

a) 1999 Clement Vieux Caperot could be found here at about HK$210 ea. (sold at U.K.). Nothing personal, for Bordeaux at this price range, pls. do not have high hope on it.

2002 Conn Creek Cabernet Sauvignon Limited Release, Napa Valley is current selling at about US$20-$25(street price). And you can find it here. This is a quite decent Napa wine for this price range.

b) To keep it in good condition, you need to leave it in dark room, cool area with some but not a lot of moisture. For detail storage information, pls. refer to my other answers here:

c) To be honest, taste is a very personal thing. Different people could perceive taste in a very different way. To me, Cabernet Sauvignon is less bold when compare with Cab Franc. Cab Franc is more bold in structure, a lot more stronger in flavor and got a more distinct character. If you are not a experience drinker, Cab Franc can really "knock" your taste buds out. That's why Cab Franc is seldom being use to make wine straight, but rather use it to serve as a "taste agent" for Cabernet base or Merlot base wine. Most of the Bordeaux style wine only use 5 to 10% Cab Franc due to it's strong aroma/flavor and grape character.

Conn Creek is one of the few wineries who make wine by using Cab Franc as base.

a) Should be around HK$200+. If it's over $300 then it's too expensive for what it is (wine in Hong Kong is very expensive because of the import duty). Don't expect a Cheval Blanc for $200+, but at this price you could do a lot worse. It's not a big chateau but run by the famous Cordier family (as stated in the label).
b) If you don't have a cellar (whether underground or a wine cabinet), then just keep it in a dark corner that is not too dry. If you have a wine cellar, then set it to a constant temperature of 10C to 15C, store the bottle horizontally, and face it north-ward.
c) Are you asking the specifics of each grape or are you simply wondering the proportion of Cabernet Sauvignon and Cabernet Franc in the Ste-Emilion? Cab Franc could be quite full-bodied and fragrant, while Cab Sauvignon (or Bouchet in Ste-Emilion) could have an astringent taste, and at times like wild fruits. I personally almost always have Cabernet Sauvignon when having steaks.
