spelling all depends on whether your talking scotch or bourbon. Jack is a bourbon whiskey while scotch is common in Britain.
Not to be too nit-picky, but Jack Daniels is not Bourbon.
Read the bottle. It is a Tennesee Whiskey.
Bourbon is made in Kentucky.
Woodford Reserve is a very good bourbon.
I also like Jim Beam Black, another bourbon.
Okay, Makers Mark, too.
Jack Daniels is NOT, I repeat NOT a Bourbon.
