Everybody has heard of Mojitos, Screwdrivers, Cosmos and Margaritas. But what about those hidden gems in the bar? The liquors that hide in dark bottles, a little bit of dust on them, that sit back watching the flavored vodkas and tequilas and say to themselves, "there was a time." From a bartender's perspective, these are the ten best drinks that you've never heard of but probably should. Keep in mind, these aren't always trendy - but there's surely a time for each one.

Negroni
This is a martini that is all kick. It's equal parts campari, sweet vermouth and gin and garnished with a twist of lemon - which 60 years ago would have been the bees knees when it came to booze.

Old Fashioned
This one is making somewhat of a revival and as vodka drinkers turn to bourbons it'll start to see the light even more. It consists of a cherry, orange and a sugar cube being muddled with a dash of bitters, then some bourbon being poured over with a splash of soda for good measure.

Singapore Sling
Its ingredients--Gin, lemon juice, pineapple juice, cherry brandy, bitters, and grenadine--read like a love letter to cocktails.

Beautiful
This drink is so simple and such an easy one to order on dates - if you've never tried one it's almost like a slap in the face to the gods of liquor. It's equal parts cognac and Grand Marnier served in a snifter.

Sloe Gin Fizz
Sloe gin is funny because every bar carries it, but no one ever really knows what it is: gin that has been steeped in plums. Next time you ante up to the bar ask for this little hidden treasure of Sloe Gin, Lemon Juice, Ice and Soda. It's a definite step up from that boring old gin and tonic.

Pisco Sour
Pisco is an addictive South American brandy made of moscatel grapes. The drink consists of Pisco, lemon juice, sugar and ice. It's a simple drink that's utterly divine.

French 75
This drink is named for French artillery during World War I. Consisting of Gin, Champagne and lemon, it packs quite a punch.

Death in the Afternoon
Equal Parts Pernod and Champagne. After knocking back a few of these you'll know where it gets its name from.

Sazerac
The real deal, wormwood soaked, cut-your-ear-off-as-you-see-the-green-fairy-float-by kind of Absinthe became legalized in October of 2007. To celebrate, order Sazerac - made with Absinthe, Rye Whiskey, Grand Marnier, Peychaud and Angostora bitters. This one will leave you hallucinating before you can say Van Gogh.

Martini
When did vermouth get such a bad rap? The original martini consisted of equal parts dry vermouth to and either vodka or gin. Next time you belly up don't fear the vermouth. If you order a martini dry or extra dry save yourself the trouble and just ask for ice cold booze of your choice served up. This is the refined way to drink, class, sophistication and skewered olives to boot.

Next time your in a bar order one of these drinks with confidence and pride - who knows, maybe you'll start the next new trend.
