Love the Glenlivet brand so when I stumbled upon this rare bottle, I had to give it a try. I didn't realize it was 60.6% when I tried it, LOVED IT. It was delicious and very smooth. I enjoyed it so much, I immediately went back and ordered 3 more bottles. This is a limited addition. After further research, I found this is the 3rd installment. Now i am on a mission to try and find the first 2: Alpha and Cipher. Hope I do!
