There's no accounting for taste. I generally just ask.
I will concur with what TravelingGentleman has said, though - Don't get too specific. If a man says he prefers wine of a certain color, I'll dig something nice out of my cellar. If he says he prefers cognac, I will pull an appropriate selection out of the cabinet. If he says he likes rum, then I will impress him with my best. If he says he likes scotch, then I'll ask him to stop by the liquor store, lol.
My point here is that other than showing the hospitality of offering him a beverage of his general choice, your liquor cabinet should be just as much about what *you* like. You may find that you two have common ground, which is always a good building block for excellent chemistry. If you're just trying to be a shell of a person and chameleon your way onto everyone's good side... not only will you find yourself ineffective at earning anyone's true admiration, you'll also find yourself missing out on the wonderful opportunity this lifestyle presents ladies like us - a chance to learn what we *really* like, and refine our tastes without financial concern.
I'm not a lush by a long shot (I rarely drink when I'm not entertaining) but I am an avid alcohol collector and am well equipped with an educated tongue. Wine isn't my expertise but I know it well, cognac is my specialty, and being West Indian I have a fierce cultural pride about my rum! I've recently learned to judge tequila since that's pretty simple, and you fine men are slowly getting me up to speed with scotch
If you don't drink, just say so. Offer a nice selection of infused spa waters and juices and ask him to bring along an adult beverage he feels would suit the occasion. In my experience most men do that unprompted anyway.
