With his prodigious constitution for drinking (and then writing about it), Ernest Hemingway shows up frequently in cocktail mythology, and none perhaps more famously than in this drink’s. First mixed up for Papa at Havana's La Floridita, this takes the original daiquiri, adds grapefruit juice and maraschino liqueur, and removed the simple syrup. KoHana adds their spin on the original by making the base rum their fantastic Hawaiian agricole style rum, for a juicier, more intensely flavored sip.
