1 1⁄2 oz Rye, Bulleit
3⁄4 oz Herbal liqueur, Green Chartreuse
3⁄4 oz Lime juice

Shake hard as all hell and strain into a cocktail glass.... Drip drops all about the top and enjoy the show


Obvious riff on last word, tastes remarkably similar, if not softer and still stronger.... Adjust rye per guest preference, of course.... By that i mean sometimes it may be prudent to add more.... Perhaps lessen overall proportions for your very serious whiskey drinkers to .5for all and 2 rye. This would need bit of sugar... Honey? benedictine? simple would not lend enough, methinks. . . .wow, its strong....


Made in Detroit at the Detroit Athletic Club... Remade by bartenders the world round since 1951.... cheers, countrymen. Here's to the beauty of composition in a simple ratio... i am about to make another

  • Tasty but definitely a sipper. Used dry curacao, as usual. Orange still a bit heavy, try reducing to 1/2 oz next time. — ★★★
  • I would likely scale back the Cointreau slightly next time but the rye does a good job of keeping it in check. — ★★★★★

"True Serum" is a solid drink, but only after some modifications. Using the basic recipe, I reduced the Green Chartreuse to 1/2 oz because it can easily overpower other ingredients. I also reduced the lime juice to 1/2 oz for the same reason. I left the Cointreau at 3/4 oz.

The drink was not as balanced in taste as I wanted, so I floated some Green Chartreuse (about 1/4 oz) on top, and that was the magic fix.

Were I to make this drink again, I would be tempted to use 2 oz of rye, but then I like a strong drink--especially with a good rye. I would also use a "tad" less lime (I am not one to use as much lime or lemon juice as a recipe calls for. I usually reduce the amount by half, and add more if I think it needs it). This is a safety precaution that has saved me from otherwise pitching a drink. It's a good practice to get into.

With the modifications I made, I rated this drink at 4.0.
