Weller 12, now also with black box. Fancy! This Weller 12 Year Old Wheated Bourbon is something to look forward to. It is based on the same recipe as Pappy van Winkle. But if they are based on the same recipe, what is the difference between this and Van Winkle? Casks? Nope. Van Winkle matures in the best spots of the Buffalo Trace warehouse, Weller is placed a bit further away. But the difference in price? Oh mama!
