I was at liquor store today that had bottles of 11, 14, 16, and 21 YO Black Maple Hill. These were all bottled in Bardstown. This means it was probably not Julian's bourbon, but from another source. The 14 and 16 YO have received good reviews on this site (despite my thoughts about some other of EK's bottlings).

They also had a 15 YO rye, but I did not check to see where it was bottled.

While doing a google search on Black maple hill, I came across a post from Julian with some history:

"I was crusing your site to see if you ever had ever writen anything about Van Winkle whiskey and noticed the questions about Black Maple Hill.
I indeed bottled this whiskey over the last few years for a distributor in Califonia. He sold it to several markets around the country, but not here in louisville. It was my Van Winkle whiskey under abother label. The ages bottled were 14, 16, 18 & even some 20-year. There was alos a rye whiskey which was mine. All the Van Winkle whiskey would have been in bottled dislaying the "Bottled in Lawrenceburg,KY" address. Since I now do all my bottling at Buffalo Trace in Frankfort, the Califonia distributor is now buying his whiskey and having the bottling done in Bardstown at KY Bourbon Distillers. The whiskey is quite differnt now. I am short of Van Winkle whiskey so I cold not acconodate the Black Maple Hill label anymore.
I hope this answers a few questions.

Does HH have 21 YO bourbon available? I know they have exported a 21YO bourbon before.
