Is the 2015 Sazerac 18 the last of the original tanked batch?
Yes. The 2015 Sazerac 18 was the absolute final release drawn from the original whiskey distilled in 1985 and later held in stainless-steel tanks to halt its aging curve. From the 2016 release onward, Sazerac 18 has come from **Buffalo Trace**'s own continuously barrel-aged rye inventories. The 2015 vintage is bottled at 90 proof (45% ABV).
Why was the old Sazerac 18 held in steel tanks?
The original 1985-distilled rye reached its perfect 18-year maturity threshold in the mid-2000s. To stop it from absorbing further oak bitterness or wood char over time, the remaining liquid was moved into stainless-steel tanks and bottled in small batches over the following years. The 2015 release officially emptied the last of that tanked stock, representing the oldest whiskey variant in the Sazerac portfolio matrix.
