W. L. Weller is a brand of bourbon whiskey produced in the United States, known for its smooth and rich flavor profile. It is made primarily from wheat, which gives it a softer taste compared to other bourbons that use rye. The brand is part of the Buffalo Trace Distillery portfolio and has gained a loyal following among whiskey enthusiasts. The bourbon is named after William Larue Weller, a pioneer in the whiskey industry who was one of the first to use wheat in his mash bill. W. L. Weller offers several expressions, including the popular Weller Special Reserve and Weller Antique 107, each with unique characteristics and aging processes.
