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 reposado is an elegant 100-percent agave tequila distilled in Guadalajara at Tequilera Newton e Hijos. The bottle is crafted in Mexico, requiring 8 workers  and 15 minutes to fabricate a single, worm-shaped bottle. Each is hand-numbered and signed.
