Substituted Wild Turkey 101, 1 teaspoon 2:1 Simple Syrup. I thought it balanced the sweet & tart components well with the tartness present but well tempered. Get a synergistic combination of blueberries and lemon juice. St. Germain was well balanced; neither disappeared or overpowering. My two critiques is that the Bourbon was too subdued for my liking and it may be a touch too sweet on the linger; I can't vouch for the effectiveness, but I'd consider bumping the Bourbon to a full 2 oz and either reducing the 2:1 simple syrup to 1/2 teaspoon or omitting it altogether.

Solid bourbon-apple drink. Great color in the glass.

Aptly named, as this is quite bitter in context, although not unpleasant. Lemon bitter aroma and flavor were pronounced, possibly due to the always problematic dash dispenser cap on the Fee's (really awful, I do best removing the cap and using a dropper for most of their bitters), resulting in two heavy dumps after an initial drop. I consider the libation good (3), but would rate it higher if evaluated as a predominantly bitter cocktail. There is some mild sweetness at the sip, while mid palate the Solbeso provides a bit of margarine and hint of cacao against the modest Amaro Nonino and more aggressive Campari contributions. Campari's grapefruit/etc. bitterness dominates the finish.

Excellent! I subbed in a softer dry gin for the aquavit, served it up, and garnished with grapefruit peel to increase the citrus influence. So good. Everyone wanted seconds.

The recipe in the recently released "The Maison Premiere Almanac" is slightly different, and they state the specific brands shouldn't be substituted:

1 oz mezcal, Bahhnez
1 oz old tom gin, Ransom's
1 oz Amaro Abano
.25 oz (fat) demerara syrup (2:1)
5 ds absinthe
3 ds grapefruit bitters

Stirred (not shaken), served up in a chilled coupe with a grapefruit twist.

Outstanding. Nicely balanced.
