Tiki and coffee are 2 of my favorite things, so I was immediately inspired to combine them for this contest. Coffee made me think of a local Ohio roaster's delicious Highlander Grogg (the only flavored coffee I buy for personal consumption!), which in turn made me think of Navy Grog and its descendants, including the Ancient Mariner. Thus the Ancient Highlander was born. I utilized 3 other Ohio products in my specs, but alternatives should be available.
Add the juices, syrup, liqueurs, spirits, bitters and coffee to a shaker tin.
Shake well with ice.
Double strain into a chilled tall tiki vessel of your choice, filled with pebble ice (or a Don the Beachcomber Navy Grog ice cone if you are able).
Garnish with mint sprig, whiskeyed cherries in a lemon boat, or whatever else floats your tiki boat to the nearest coffee roastery.
