One thing a bartender strolling through a package store would almost never shell out for is flavored spirits. Think orange or peach vodkas or honey bourbons.
You're essentially paying more for less percentage spirit, and for very simply conceived, easily achievable flavor profiles. That's unlike, say, other low-ABV liqueurs like Cynar or Fernet-Branca, whose complex recipes comprise a secret mix of dozens of herbs and botanicals — those we will gladly shell out for.
If you're looking to spice up the flavors of the home bar bottles, opt for infused spirits instead, like Kettle One's Botanical line.
You get the additional punch of flavor, while maintaining the same percentage of alcohol by volume.
Again, there are exceptions. I can't seem to make my own RumChata no matter what different horchata and rum combination I try. And I hate to miss out on indulging my favorite two-ingredient summer tiki drink, the SnoMageddon.
