William Larue Weller is built on Buffalo Trace's wheated recipe — Kentucky corn distillers grade #1 and #2, North Dakota wheat in place of rye, and North Dakota malted barley to finish. The 2015 release was cooked through a #10 milling screen at 240 degrees on Kentucky limestone water, fermented sour in carbon steel and black iron, then double distilled through a beer still and doubler to come off at 130 proof. It entered new white oak — #4 char, burned for 55 seconds, coopered by Independent Stave, 53 liquid gallons a barrel — at 114 proof, and matured 12 years and 3 months on the second and sixth floors of Warehouses I, K and L. Evaporation took 72.3%. Buffalo Trace bottled the release uncut and unfiltered at 134.6 proof.
