On a recent visit to Liquor Barn in Louisville, I was pleasantly surprised to see Weller Centennial priced at $22.99 while its former stablemate in the Bourbon Heritage Collection, Very Special Old Fitzgerald, is still priced at $30+. I bought the Centennial and a bottle of Old Fitzgerald 1849 for $14.29.
The Weller line consists of:
W.L. Weller Special Reserve (7 years, 90 proof)
W.L. Weller Aged 12 Years (90 proof, $14.99)
W.L. Weller Centennial (10 years, 100 proof, $22.99)
W.L. Weller Antique (7 years, 107 proof, $17.99)
The prices given are actual prices I've paid within the past year in Chicago or Kentucky. I don't have a recent price for Special Reserve, but it would be at the low end of the above range.
