Pedrini Stainless Steel Double Jigger

However, as other reviewers rightly point out, this is not the usual size for a jigger, and it is an odd measurement amount of 1-1/4 and 3/4 oz, when most drinks are calling for multiples of the half-ounce in the ingredients.

Still, this is handy for some of those classic cocktails that require some odd measurements/rations of ingredients (such as the Aviation or Floridita), where you will need 1-1/4 ounce.

So get this one, because you will likely need it if you truly venture into the world of classic cocktails, but get yourself first the standard size jigger first. Or better yet, get both and a bottle of marschino liquer (if you can find it) at the same time, and go home and whip up yourself an Aviation, and wax nostalgic of days gone by when bartenders knew how to bartend, and the US hadn't yet invented the abomination of the blended Daquiri or blended Margartia.

Also get yourself a copy of Paul Harrington's "Cocktail: THe Drinks Bible for the 21st Century", the essential cocktail book that will explain and show you how to make a true cocktail, sometimes even how to enjoy it, and teach how not be a cultureless alcohol-obsessed buffoon who thinks sugary, alcohol-taste-covering drinks are "all that" so that you can go to a fine bar like the Rainbow Room and order drinks like Cary Grant or James Bond knew how to do, and not order them like you're a college Freshman or a newly-minted MBA on an expense account. Then get yourself a copy of the Waldorf-Astoria cocktail book.

Also you'll want a good shaker, martini glasses you left in the freezer, and some good friends for conversation as your lips become loosened and the words and ideas flow like water from your mouths.
