This is what we found out.....
The Glenfiddich 21 “Gran Reserva” was indeed the way it was labeled when it debuted about four years ago in the United States. During a global package refresh last year, the word descriptions were removed from several of the Glenfiddich variants, including this one. It is now known simply as Glenfiddich 21. It is the same smooth, flavorful liquid with toffee, caramel and leather aromas and tastes as originally launched. So, that means you are certainly correct with the general description of the colors of the old and new labels. And by the way, we're told Glenfiddich 21 paired with crème brulee or rich chocolate at the end of a nice meal is heavenly. With a fine cigar is rather wonderful, too. And I for one would certainly have to agree with this suggestion!
