La Perla de Oaxaca

The idea of coffee being involved here makes sense, but it isn't working for me in execution. Thinking maybe a a barspoon of something like St. George's coffee liqueur in place of the coffee bean might do the trick, perhaps as a float. The grated coffee bean, for me, just feels like someone spilled coffee in an otherwise fairly tasty drink.

Delicious flip. May try without the simple. And: why a lowball rather than coupe?

I liked the ground coffee, but using a standard microplane for this was a pane.  Need something other than my fingers to hold the bean to a fine grinder.  I might try to use my hand-cranked conical burr grinder tuned to the finest setting without the basket in place.
