Cinnamon syrup really didn't do much for me. Preferred with simple syrup and Demerara rum.

A new tiki classic! I tried a touch of tiki bitters second go, and it's a great addition.

This is a great daiquiri variation!  

Very sweet as written. I upped the scotch to 2 oz (Bowmore Legend). I also erred and doubled the Chartreuse. Probably best as written. I'm not sure what the last bitters is though. I could not taste one drop of celery bitters.

Stew,

Love the thought of anejo tequila + Cynar playing together. What sweet vermouth do you recommend? Dolin might be nice...

My sweet vermouth of choice is Cocchi. Dolin could be nice, too! Carpano Antica might add a bit too much bitterness to an already bitter drink.

Really nice, well-balanced cocktail. Only had Cazadores reposado around, but it played nicely.

My changes address the questions or issues raised in the above three Comments. I used 1.5 oz El Tesoro anejo tequila, 1 oz Cynar, and 1 oz Dolin sweet vermouth. Also used Bitternens Hopped Grapefruit bitters and Angostura Orange bitters. And the lemon peel, of course. Great drink! Very smooth, but a tad too sweet for my taste. Perhaps 0.75 oz Cynar for less sweetness? Rated 4.5 as I made it. Enjoy!

Curator note and variation: A user (name inadvertently lost during a merge, my fault) submitted a "T and 3C" variation which is nearly identical in ratios but suggested Cynar 70, with celery bitters in place of the orange/grapefruit bitters, and an olive garnish. I am listing it here so that others can try if interested in a slightly hotter, more vegetal take. 1 oz each Anejo Tequila/Cynar 70/Cocchi di Torino Sweet Vermouth with 1 dash Bitter Truth Celery Bitters and stuffed olive garnish. The 3C's presumably refer to Cynar/Cocchi/Celery.

An easy to make and easy to drink cocktail. Somewhat sweet, but not overly so; the rum sees to that. One might be tempted to put in a TAD more Gran Classico; I know I was (but didn't). Maybe next time. I rated this one at 4.0. Meanwhile, drink up but drive responsibly.

I had a version of this from Mindy Kucan that was as follows: Crush 1 sugar cube in the bottom of a Collins glass. Add 15-20 leaves of mint and press lightly. Add 2 oz. Matusalem Platino, 1 oz lime juice and 3/4 oz Demerara syrup. Stir, then fill the glass with crushed ice. Swizzle and top with 6-8 dashes of Angostura bitters.

Fine drink but I increased the lime juice to 1 oz and rich simple syrup to 3/4 oz. I often find that 1/2 oz of lime is too little when calling for 2 oz or more of spirit. Of course, this is a matter of preference much like in a Daiquri where some recipes call for around 1/2 oz of lime. A tastey swizzle.

Tried this with ginger syrup instead of honey, it was excellent.

A nice twist on the Trinidad Sour idea. Used Ardbeg as the Scotch and actually served it in a small Old Fashioned glass with an ice cube as it was a bit balmy out. Delicious. Would drink again. 

I used Sipsmith Sloe Gin and cut back the apricot liquer to 1/2 ounce.  Loved it, my friend was "not as enamored with it" but i thought it was tart, sweet and delightful!

I'd appreciate a suggestion for a brand of Apricot liquer. I used Sipsmith for the Sloe Gin and a small batch local number for the apricot. Mine came out too dry but I think a sweet apricot spirit would address that. I added a couple bar spoons of simple and it was much better.

Rothman & Winter Orchard Apricot is the only apricot liqueur I've tried. It's high quality and plenty sweet. (In fact my quest has been the opposite: to find an apricot brandy to try in vintage recipes for which this liqueur is too sweet!)

I developed this with Luxardo Apricot Liqueur. I love it, and find it a bit less sweet (and a tad more complex) than the R&W, though both work great in this drink. Cheers!
