The hand-blown worm bottle may strike some as little more than a conversation piece, but to tequila enthusiasts, the spirit inside is something of a find. Casta Pasion Anejo is an elegant 100-percent agave tequila. The bottle is crafted in Mexico, requiring 8 workers 15 minutes to fabricate a single, worm-shaped bottle. Each is hand-numbered and signed. Where the worm gets its 2 front legs has not been determined. The Casta Worm Anejo is aged over year in new white oak casks. The fresh barrels imbue the tequila with a pronounced woody, oaky character, as well as a palate rich with the flavors of sweet spice, citrus fruit and ground black pepper.
