One of the reasons Fortaleza is so great is that they do everything the right way, even if it's the hard way. Here's how they make their bottle caps, molds, paint, and then sand them down. Here's how they sand down each and every bottle cap on each and every bottle of Fortaleza tequila. Who would put forth this kind of effort?
Six full-time people doing nothing but making caps and corks. Wow!
