Did E.H. Taylor invent the sour mash process?
No, and retail copy for this bottle sometimes says otherwise. The sour mash method is credited to James C. Crow, a Scottish-born chemist and physician who perfected it in Kentucky in the decades before Taylor bought the O.F.C. Distillery in 1869. What this release reconstructs is a specific variant associated with Taylor — allowing the mash to sour naturally over several days before fermentation, rather than the setback method used across the industry today.
How old is Colonel E.H. Taylor Old Fashioned Sour Mash?
Sources disagree. The 2002 distillation date is consistent everywhere, but published bottling years split between 2011 and 2012, giving ages of roughly nine or roughly ten years, and at least one retailer lists eight years while describing the bottle as just under nine in the same description. No Buffalo Trace figure is in general circulation. Treat any single number you see as unverified and check the label.
What is old fashioned sour mash?
It refers to letting the mash sour naturally over a period of days before fermentation, which lowers its pH without adding spent mash from a previous run. Modern sour mashing achieves the same end quickly by adding setback, and effectively all bourbon is made that way, so the distinction here is method rather than category. Buffalo Trace reconstructed the older approach from the recollections of distillery retirees describing how it was done in Taylor's era.
