There are no "buy" links on this page because of this older bottling but Centinela Reposado can be found at some on-line retailers and links are provided on the next page.
It looks as though I.P.N. is the current importer of Centinela but interestingly enough their website only mentions the Blanco and the Reposado.
Once imported by the now defunct El Dorado Importers out of Santa Rosa, New Mexico, Centinela was quite prevalent here in the States in the mid 1990's. Tequila Centinela is a proud company with traditional production methods and very well respected in Mexico so I'm not too surprised to see that Centinela has worked out a deal with a new importer and reappeared in some markets. In Mexico it looks as though the older look of the previously Mexican bottles is now being used for all Centinela varieties except the 3 year añejo which uses this look that was originally developed for exports.
