I was just reading an article that it is legal to make your own rum for your own consumption (also know as Pitorro) if it is created during the months of November, December and January. Provided you have gotten a permit which cost $100.00. I assume that personal consumption has some sort of number of ounces attached to that but I don't know what that number is.
I think this is a unique thing in the island, never heard of it. I have heard of wine and beer in the states but no license and no specific time period.
Any other weird thing you found out that most people don't know?
** The now commercial brand Pitorro used to be illegal, now with taxes and a legal company, you can get it at any store.
