The nose is Hawaiian Punch with some brandy notes. On the palate, it's a huge fruit monster with tutti fruity notes. The finish is light and sweet with a dash of spice in the finish.
This has a surprising lack of rye character, particularly compared to Old Potrero's other offerings. The last Hotaling's I had was the 11 year old which had much more rye character; I definitely preferred it to this one. While generally good, the 18 year old is very fruit forward without much in the way of rye.
