And speaking of Cabernet sauvignon (CS), I have been fortunate enough, of late, to have tried quite a few old bottles of CS: two were from 1988. Thankfully, I didn't have to pull the corks on any of the older bottles.
Old corks can be a pain in the bottom to get out of a bottle. I've been told on many occasions that the two-pronged Ah So cork puller is the only thing to use to extract a vintage cork, specifically any wine that is 10 years old, or more. I would generally agree, except that sometimes, when a cork is particularly compressed, the prongs of the Ah So will push the entire cork into the bottle. In my humble experience, every older bottle of wine is different because the condition of the cork can vary dramatically.
On attempting to open a bottle of Altvs, 2007 Cabernet Sauvignon (Napa Valley AVA), I could immediately tell that the cork was not going to cooperate. I was right. At only 10 years old, the cork was past its best and I had to use an Ah So to coax it out of the bottle. The cork broke into three pieces. Fortunately, the wine had not been compromised. The two bottles of CS from 1988? They were opened with a traditional corkscrew.
