Recently I was asked if the source of Knappogue Castle Irish Whiskey is from Bushmills. I thought it might something of interest to all of you. The answer is, in chronological order by release: no, no, no, no, yes, yes, yes, and no.

To clarify:

The first vintage, 1951, was from the B. Daly Distillery (where Tullamore Dew was once made)
 
The next three, 1990-1992, were from Cooley
 
The next three, 1993-5, were from Bushmills
 
The last one, a 15 year old non-vintage, was once again from Cooley (a marriage of stocks from 1990-1992).

I hope this helps.
