Tequila Aha Toro is produced at the same factory that has brought us products like Oro Azul and 1921. Bob Emmons wrote in his 1997 book "The Book of Tequila" that this factory was owned and operated by cousins of the Camarena family. The Camarenas are the long time operators of Tequila Tapatio (El Tesoro de Don Felipe). This Tequila is sold in the U.S. under the name of "Aha Yeto". According to Erin Johnston of Pale Horse Imports this is due to a trademark conflict with the word "toro". Mr. Johnston also informed me that Aha Yeto is currently (06/2004) available in CA, AZ, and soon in GA, & IL. and added that this reposado is 6-8 months and Aha Yeto Añejo is aged 3yrs.
