那一種紅酒類會比較保存得久?

Cabernet and Cabernet Sauvignon 含量高的通常能於入樽後仍可長時間保存，因此種葡萄的丹寧(tannin)較高。

Tannin - Found in grape skins, pips and stalks, tannins are harsh, bitter compounds which if present in large amounts make a wine difficult to drink as they leave a dry, puckered sensation in the mouth - rather like drinking stewed tea, which is also very tannic.

The amount of tannin can be increased by enhancing extraction, achieved by prolonging the cuvaison. Tannins may also enter the wine from oak barrels. Tannic wines are generally destined for ageing, the tannins polymerising to form sediment with time.http://www.thewinedoctor.com/glossary/t.shtml

牌子年份就不知道，但如果酒瓶上註明是RESERVED的酒，表示酒在瓶內仍會有變化，通常可以保存約5年不會變壞(溫度濕度正常儲存情况下)。
