Murray Stenson, Seattle's well-known and highly-regarded bartender (Zig Zag Café, Canon, 2010 "American Bartender of the Year") has a heart condition that will require an expensive surgery to allow him to return to work. Like many bartenders, he lacks health insurance. While we have not had the pleasure of visiting Murray in Seattle, we have certainly enjoyed some of his recipes and have heard tales of his hospitality.
Good and certainly not objectionable, but more a 3 than a 4. Bourbon makes this more of a spirit heavy boulevardier riff than black Manhattan riff (rye), although the wormwood bitterness and citrus zest of the Montenegro (plus lemon twist) provide more bitter balance than one might expect from the bourbon base. I admit I am not as keen on Montenegro's floral character compared to other amari.
I didn't shake this, the lack of citrus juice would contraindicate doing so.
Skipped agave syrup, subbed mossy Oaxacan forest mist spray (from Shaker and Sppon) for Douglas fir eat de vie, and subbed dry curaçao for the blue stuff. The Del Maguey seemed to flatten it our a bit so I added a squeeze of lime which worked for me.
The slightly mossy gray/green is what I get with R&W Creme de Violette and St. Elizabeth Allspice Dram that I used. The 1/2 oz total of floral components (violet and elderflower) turns the drink into "A Florist" more than "A Forest" though. It isn't unpleasant, but the floral components dominate. Maybe cutting them to a barspoon each and adding some Zirbenz or Douglas Fir eau de vie would shift the balance?
