SAN FRANCISCO — A startup in San Francisco is trying to make an aged whiskey that’s never seen the inside of a barrel and can be produced in about 24 hours.

The first bottles of the result — a product called Glyph, billed as the world's first molecular whiskey — recently hit shelves, retailing for around $35 each.

Endless West, which manufactures Glyph, begins the process by studying existing popular aged whiskeys at the molecular level, to understand and map the flavor profiles. Endless West then builds Glyph from scratch by adding a plethora of different chemicals to medical-grade alcohol. The entire process is completed overnight.
