Thanks so much for submitting a report. It has been emailed to the Rum Captain and will be actioned shortly.
58.5% ABV. Extremely bourbon-y. Nose and palate both a bit light and a bit too astringent. With water, marshmallows. Medium-short finish.
A rare example of where the high-strength version is actually not as good as the lower-strength. I think the ideal would be somewhere in-between; say, 45–50%. No need for two expressions. (Or they should do something different with this one to improve its quality/ flavor-strength ratio.)
