The newest release in the L'Atelier line may just be their best. The extension de la Racine ER13 made using some Sancti Spiritus tobacco which is a hybrid of the Criollo and Pelo de Oro seed. The ER13's double binder is Sancti Spiritus leaf grown by the Oliva Tobacco Company in Ecuador wih the filler consisting of Nicaraguan tobacco and Sancti Spiritus leaf grown by the Garcia Family in Nicaragua. A definite medium to full bodied experience, but one you must have.
