What is the origin of orange peels in Cointreau?

In order to guarantee the constant quality required by Edouard Cointreau's original recipe, we are constantly looking for the best orange peels in the four corners of the world. Thus, each year, our Master Distiller Carole Quinton  plies the planet, seeking out the finest terroirs and the most aromatic oranges. Cointreau’s orange quest takes Carole Quinton, our master Distiller, to Brazil (Barra Bonita, 300 kilometers north of Sao Paulo), Tunisia (near Cap Bon), Ghana (to Asebu, Kruwaet, Nsanien Central Region), Morocco (around Marrakech) and Spain (for fresh peels from Andalusia).
