Ok, so as it may or may not be seen on my posts, I am and have always been a tequila drinker through and through, give me a bottle of Don Julio 1942 and I will be the happiest man in the world. However, to my surprise, a family member gave me a beautiful bottle of unopened 20+ year old brandy that she just happened to find in her house. The brandy was a christian brothers tricentennial (stored in the crystal decanter made by tiffany's), and while I know it probably wasn't the best brandy by any standards, it has definitely peaked my interest. While the taste has for some reason changed significantly between the first and second time I tried it (I think it must've somehow gone bad or something after we opened it because the second time it was the most foul thing I've ever tasted), the scent of the brandy especially when I first uncorked it was beautiful and rich.
So please, I know very little about brandy, but if I could taste anything that smelled so wonderful I would be very grateful, what do I need to know about brandy, what do I need to know/do in order to enjoy brandy, how can I tell what is good/bad brandy? What do you recommend?
