I am quite new to enjoying anything but vodka. I'm building a home bar and have purchased Rum, Tequila, Vodka, Whiskey and just recently Cognac.

Which brings me to this question: I purchased an XO Extra old Cognac after some research online. Well...my initial 'nosing' was it was just like my scotch whiskey. Is it suppose to be this way? Will my nose eventually be trained to distinguish the differences?
