Okay, folks, we are in luck. There’s a foreigner in Tainan named Seamus who is selling some pretty decent rum. Right now he has Foursquare & Doorly’s from Barbados, Hampden from Jamaica, and Mezan, an independent bottler of various regions. All of the rums have no added sweeteners or flavorings, and only one has added color. ABVs range from 40% - 63%. All the information is in Chinese, but he can explain everything to you in English. Highly recommended.
(I have no financial or personal interest in this venture. I just like good rum.
