Indeed, Beer may be God's gift to man, but spirits are his best weapon! Whether it be Gin, Vodka, Whisk(e)y, Brandy, Tequila, or Rum, spirits have succeed in getting men drunk and writing some of the best novels and poems mankind has ever seen!
Straight up, on the rocks, or in a cocktail, Spirits may make your spirits go up and down, but they always lead to interesting discussion!
Perhaps we should state at the begining that distilled beverages are NOT beer or wine - you cannot really drink them the whole night and feel great the next morning. They can be incredibly dangerous. I am a strict believer that you should only have one or two, and then switch to beer, unless you are spacing them out over a long long period of time.
Me, I'm a gin guy. I love just how smooth it is, how lightly flavored it is, so that the taste of the alcohol is dry, yet there is still some flavor to it. Screw vodka - Gin is THE mixing drink. Gin and Tonics, Martinis, Tom Collins, Sloe Screw, Salty Dog - a high percentage of the best drinks use gin as their base. Bombay Sappire is my usual buy, though Hendricks and regular Tanqueray are also great.
Scotch has recently made it's way up my list thanks to my roommate. We recently bought a bottle of Dalwhennie aged since 1990. It was one of the smoothest things I've ever had. No bite what so ever. Whiskey (which gets it's name from a Gaelic term for drink of life - akin to aqua vitae) is my favorite drink straight and on the rocks.
I am not a big fan of vodka. Totally overrated in my opinion.
