Weller Antique 107 is a wheated Kentucky Straight Bourbon produced by Buffalo Trace Distillery. Named after bourbon pioneer William Larue Weller, it uses wheat instead of rye for a smoother profile. Originally part of the Stitzel-Weller legacy, it’s now highly sought after. Bottled at 107 proof, it’s believed to be aged 7–10 years in new, charred oak barrels.
