Carib is the name of the beer. We actually took a tour through the brewery on another time we stopped in St. Kitts. Free samples are always good!
I also must have the local beer at each port. I try to carefully pull off the label from a bottle for a souvenir. Or if that doesn’t work, ask if I can have a coaster if that brand is on the coasters the bar is using. Have never been told no.
