Time again for another chapter in the celebrated series "Stupid questions posed by HB".

I throw caution to the wind and wonder about the term "Presidentīs reserve". As far as I know this is used for two bourbons : Hancockīs P.R. and (the possibly discontinued) I.W. Harper P.R.

My question is : is this a term that carry any obligations or can you just use it at your own convenience, for instance, in conjunction with a luxury product?

In Sweden we have something called "By appointment to His Majesty the King", which coupled with the Royal coat-of-arms can be found on various products.

Is Presidentīs reserve an American equivalent to this or is it just wantonly used?
