Inaptly Judging a Drink - Color

In my opinion, too many drinks are judged by one of these three things, when they should be judged by their taste, liquor content, and history.

I'll tackle color first - once you've made a few different types of cocktails, you start to recognize the colors and textures of different types - the telltale creaminess of a drink with egg whites, the (surprising) rosé of a whiskey cocktail, the silky-clear top to a gin drink. If you drink Manhattans often, you might have already had this conversation before:

You walk into the room or across the bar with a nice Manhattan in a cocktail glass
"Whatcha got there, girlie-man?"
"A Manhattan."
"What's in it? Unicorn tears and heartstrings, why not drink a real drink?"
"Whiskey. Vermouth. Bitters. A few of your teeth soon."

The problem is, even with the recent renaissance in the cocktail world, few people even know the history of the word cocktail, let alone the storied past of drinks ranging from the Pink Lady to the Papa Dobles. Here in America, the birthplace of the cocktail, a drink that isn't clear or silty brown comes with the presumption of feeble drinking abilities.

Now, sometimes it is appropriate to judge - or at least assess - a cocktail based on its color. However, you should first verify your suspicions by a hearty taste, and perhaps a request for a trial cocktail on the house. Once you know for sure that the yellow-green-neon concoction with a parasol and a fruit bouquet is indeed dreck, then go ahead and assume all the matching drinks on the premises are of similar quality.

All of this goes to the point that while a Duchess might look girly, it's 1/3 absinthe, and the other 2/3 vermouth, so back off you dolt.
