You can make variations replacing lemon zest with lime or orange. Instead of smokey flavors, try adding small amounts of herbs like tarragon. The recipe @luxirare uses gin with lime zest and an assortment of peppercorns. If you like fruity flavors of high-quality bourbon, you might also want to experiment with your favorite cognacs or grappas. You won’t feel the alcohol in the final product, only its characteristic aroma.
