It sounds like you're describing a whiskey that is made using Pennsylvania rye and aged for a minimum of two-and-a-half years, and it is produced by the oldest historic distillery in the United States. Pennsylvania rye is a type of whiskey that is made with a high percentage of rye grain in the mash bill, which gives it a distinct spicy flavor profile.
The fact that the whiskey is aged for a minimum of two-and-a-half years is significant because it means that it meets the legal requirement to be called "straight whiskey" in the United States. Straight whiskey is aged for at least two years in charred new oak barrels and must meet other requirements set by the Alcohol and Tobacco Tax and Trade Bureau (TTB).
The fact that the whiskey is crafted in the traditional Pennsylvania rye style is also significant because it means that it is made using traditional methods and ingredients that are specific to the Pennsylvania region. This may include the use of a specific strain of rye grain, a particular fermentation process, or other techniques that are unique to the style.
Finally, the fact that the whiskey is produced by the oldest historic distillery in the United States adds to its appeal and authenticity. This suggests that the distillery has a long history of producing high-quality whiskey and has refined its techniques over many years.
