Killer Kahlúa is a homemade variation inspired by the famous coffee liqueur originating from Mexico, known worldwide as Kahlúa. This liqueur was created in the 1930s in Veracruz, and its name comes from the indigenous word "Kahlúa," which means "House of the Aguardiente." In Latin America, this type of coffee liqueur may have different names depending on the country, although the traditional recipe maintains similar elements throughout the region. In countries like Argentina or Chile, homemade versions are sometimes known by generic names like coffee liqueur or café liqueur, adapting the ingredients and intensity according to local tastes. Killer Kahlúa stands out for the intensity of its flavor and its higher alcohol content, thanks to the use of Ron Monarch 151, making it an ideal drink for those who prefer a more potent touch in their coffee liqueur.
