So... I received a bottle of Pappy 20 for Christmas this year. Looks like it's one of the older bottlings, based on information I received from Julian.

I just received a bottle of ORVW 15 yr old (well, that's what I ordered... it showed up as Pappy 15 instead - not sure why they still list it as ORVW 15). The color, nose and flavor is very different from my Pappy 20. Is this due to the difference in age, or the difference in the source of the whiskey? Or both?

I almost think I prefer the 15, but every time I think that I pour myself a tiny bit of the 20, and then I'm confused again...
