If it says Bourbon,Just buy a 1/2 pint of JACK. You cant go wrong.
Being a bartender/manager more yrs then I can count on my two hands.See if this helps.
Differance between Brandy and Cognac......NONE,the only thing that makes them differant is that Cognac comes froma Region of FRANCE were the Brandy is Distilled,witch happends to be by the city of Cognac,France.Thus the name Cognac.
It just sound like you have money(or trying to have class)when you order a Cognac over a Brandy in a bar.Basically you paying more to drink a Brandy from France over one beingmade somewhere ealse.
end of story.
