Weller - Full Proof Wheated Bourbon is produced in the United States using a mash bill built around grains such as corn, rye, and malted barley. The mash is cooked and fermented before being distilled, often in copper column or pot stills.

Maturation takes place in new, charred American oak barrels, where seasonal temperature swings drive spirit deep into the wood, extracting color and complexity. Warehouse management and barrel selection are critical, with blenders assembling lots that best represent balance and structure.

The result is a whiskey shaped by grain, oak, and time, reflecting both traditional craft and rigorous quality control.
