JOJO! i have been all over the internet trying to figure that question out and you have come up with a great answer. see, i bought the Havana Reserve many years back when i was in Scotland on the scotch tour. i have been trying to find it ever since. Only recently have i found some literature on it and found that it became the Gran Reserva and then the 21. so i bought the 21 and did my own taste test and found that they were very much alike. the only problem i have is that you can still find the Gran Reserva on the internet and buy it under that name. Is it truly the Purple lable 21 year old GlenFiddich?
