Interesting, two brothers, two different but wonderful liqueurs.

St-Germain elderflower liqueur hit the scene in 2007 and quickly gained near-ubiquity in high-end bars, finding its way into a flock of original modern cocktails; Domaine de Canton ginger liqueur got going in earnest last year and is on a similar trajectory. Both liqueurs are made in small batches in France, both are presented in elegantly executed trophy bottles, and both have been enthusiastically praised (in 2007, St-Germain was judged best liqueur at the San Francisco World Spirits Competition; in 2008, Domaine de Canton took the prize). Remarkably, these back-to-back successes were executed by a pair of brothers, John and Robert Cooper. More remarkable still, they didn’t do it together. Each has his own liqueur company, and their triumphs seem to be born of a sibling rivalry that isn’t always cordial. – from WSJ
