Gold Bar Diamond Edition is a very limited release 18-year-old straight American whiskey crafted in San Francisco and finished in French oak cognac barrels, then further treated with toasted French oak staves to impart a smooth and elegant character.

This expression is a collaboration between Gold Bar Whiskey and Los Angeles-based celebrity jeweler Kyle Chan, known for designing jewelry featured in the Oscar-winning film "La La Land." The result is a collectible, ultra-premium whiskey that pairs a distinguished aging pedigree with an artisan aesthetic.

The cognac barrel finish layers complexity onto the long-aged base spirit, contributing dried fruit, oak spice, and a refined sweetness. The toasted stave treatment rounds out the palate for a polished, approachable finish befitting an 18-year whiskey. Each 750ml bottle is part of a numbered, limited-availability release sold at Costco.
