Cristalino is a style of tequila that some distillers (including Volcan, of course) are pushing to be included as a new category of tequila.
It’s an anejo or extra anejo tequila (or in this case a blend of the two), which is then filtered, usually through charcoal, to remove some of the color that it’s picked up in the barrel. Charcoal filtering is also usually the way most distillers filter vodka or bourbon or whiskey, to purify and concentrate the flavors.
In the case of Volcan’s cristalino, their anejo and extra anejo tequila are blended has been aged in ex-whiskey barrels and the extra anejo in former cognac barrels.
