This particular style of aging is most associated with rum (spirits) or sherries and port, but wondering if it has ever been utilized for aging bourbon (or other American Whiskey).

I know of Jacobs' Creek, which could be argued as a basic style of the solera method, but I understand it was a failure... for this reason, or another reason.

Could bourbon aged the solera method be actually labelled as bourbon? Having studied the regulations, I believe so!
