An agave cousin of Mezcal and Tequila, Raicilla was illegal to produce and distribute until very recently which is why you might not have heard of it despite its 400 year history. You can almost think of it as Mexican moonshine, only made by small family productions for local consumption until commercial production became legalized.
Flavor-wise, it's more fragrant and fruitier than its cousins. This particularly beautiful one from Estancia in the Highlands of the Sierra Madre is extremely bright and energetic, with just a kiss of smoke to complement the desert fruit and mildly floral notes. Outrageously sippable, this is perfect just chilled down and served with bit of chili salt and a slice of orange...but we wouldn't hate it in a Mexican martini either.
