Is Weller 18 a bourbon?
No. Weller 18 Year Old is a straight wheat whiskey, which is a separate federal category requiring wheat as the majority grain. Every other Weller bottling is a wheated bourbon — a corn-based mash with wheat replacing rye as the secondary grain. This one reverses that relationship, which is what makes it a departure rather than an older version of the same whiskey.
What proof is Weller 18 Year Old?
90 proof, or 45% ABV, in a 700 mL crystal decanter. That is the same strength as Weller Special Reserve and Weller 12, and well below the 107 of Antique 107 or the 114 of Full Proof. Master Distiller Harlen Wheatley has described 90 proof as the classic register for the brand.
Where was Weller 18 Year Old sold?
It launched exclusively through global travel retail — duty-free shops at airports including LAX, JFK and London Heathrow — rather than through domestic distribution. Buffalo Trace announced it on 25 July 2025 alongside Weller Millennium No. 2, timed to the 200th birthday of William Larue Weller.
