I been to Salegua distillery, the only one on the island. To find where it;s located, if you are coming off Air Port road and going to Mary's Boone turn right on the first road and it will be on the left side of the rough street, the whole opperation is there. If you can't find the place ask at Ace car rental, last I knew the owner was in the car rental business also.
I've been to Topper's and they were just flavoring and coloring the rum.
