Mixology Monday: South of Tuitan

This month's Mixology Monday, hosted by The Barman Cometh, challenges participants to devise a cocktail using a floral ingredient.  This theme dovetails nicely with a cocktail I'd been playing around with, whose final iteration I've named South of Tuitan.  From the beginning, the intent was a subtle but flavorful drink based on blanco tequila and featuring Elderflower Liqueur or Creme de Violette as well as grapefruit juice and some sort of bitters.

For this cocktail, I sought to feature the flavor profile of the tequila while hosting an interplay between the grapefruit juice and the floral liqueur.  After playing around with the ratios, use of red or white grapefruit juice, use of Angostura or orange bitters, and stirring or shaking, the final version is as follows:

South of Tuitan

Ingredients:
1.75 ounces of blanco tequila (Tres Generations)
.5 ounce of elderflower liqueur (St. Germain)
2 dashes of orange bitters (Bitter Truth)
.75 ounce of red grapefruit juice

Directions:
Stir ingredients with ice, pour into a chilled cocktail glass, and garnish with a twisted grapefruit peal.

Outcome:
I think that the drink works really well.  The orange bitters kept the aftertaste from coming off too sweet, while playing up the citrus of the grapefruit juice.  The swallow first features the tequila and gives way to both the grapefruit juice and the St. Germain and I believes maintains good balance.  I think that the drink works with Angostura bitters as well, though they are a more assertive portion of the flavor profile than orange bitters.
