Wake up to "Goodnight Vienna!" What a wonderful drink, despite what one might think is an incongrouous mixture of alcoholic ingredients. In reality, they are incredilby congruent--almost beyond belief, until you sip on this delightful concoction. I mean, Grand Marnier and Ramazzotti! Come on; who in their right mind would mix them together? And then to throw in some Mezcal! Get me a head shrinker!

But pull yourself together, mix the drink using the given recipe, and you'll end up with an incredible before dinner drink, or a very satisfying late evening drink. I rate this libation at 4.5. Come on--mix, stir, strain, and then drink up--but do it responsibly!

Boosted ramazzotti and grand mariner by .25/ea for a more balanced drink for my palate with mezcal- got better.

Mezcal is slightly overpowering - dial back to 1 oz

No... don't drink this. I am not sure where this came from.. and should have used that as a sign to not drink it and to pay more attention to the ratios in which case I would have realized. A tablespoon of matcha powder makes this undrinkable, which I should have realized. Went looking for ref and a bullshit Dr. Oz website as "health" because of cucumber and matcha. May try to rebalance, idea may have some potential but don't try with this much Matcha.

Responding to a trademark request to rename this cocktail, the editor changed it from Hurricane Irma to Hurricane I 2017. See the history. The cocktail's creator should feel free to pick any other name if desired. While I don't acknowledge that the Intent to Use application filed with the USPTO affords the applicant the right to prevent the publication of this recipe, Kindred Cocktails has a "don't be a jerk" policy and does not wish to publish a cocktail using a disputed name. Take your legal fight into the alley out back, please.

As for the cocktail itself, we haven't tried it but it sounds like an interesting sour -- rather unlike the horrid intoxicant poured by the gallon on Bourbon Street to induce public emesis.

What a crazy world.

I think the possible trademark infringement makes the cocktail taste better.

Will change the name from "Hurricane I 2017" to something else.

I used Angostura 1919. The vanilla notes pair very well with the bitter cherry of the Amargo Vallet and the spice of the Falernum. This is really tasty.

I just tried this one and I really enjoyed it! I used aquafaba instead of the egg white (as suggested in the note), which gave the drink a little hint of savory nuttyness. I took the advice of another commenter and upped the Amargo a touch and went a light on the falernum, which I think was a good choice. I also replaced the Trinidad rum with an ounce of Barbados rum (Mount Gay) and a quarter-ounce of a dunder-heavy Jamaican pot still rum (Dr Bird). It all came together to make one of the strangest cocktails I've ever built — but in a good way! Rich, creamy, nutty, funky, and surprisingly well balanced. Big thumbs up from me!

Yea, the Falernumn is awfully high. I'm not sure what the idea was when I made this (apart from Trinidad and Mexico having to be a part of it). Also, IMHO it needs a little simple syrup. I've edited it a bit.

This is a real gem. Lacking a T&T rum in my quiver, I used Hamilton 86 Demerara, and oh man. This'll be the one to take the "edge off" after a long day of selling dinettes and bar stools. No matter your toil, I highly recommend suppressing your woes with this brilliant cocktail. Sláinte!

Slightly modified. Used orange superjuice, which is acid corrected, so dropped the lemon and upped the orange to a full ounce and it was delicious.

Quite a boozy delight.  I really enjoyed this despite the fact that I had the wrong beer on hand (a carmelly lager instead of a crisp dry IPA).  Will try again with the correct beer. 

Love the original, but I make a low ABV version of this with Giffard Apertif syrup (instead of Campari) and Athletic's Run Wild IPA (both non-alcoholic). Keep the tequila for what results in something with about as much alcohol as a radler.
