The Guinness Stout available in Jamaica is Guinness Forein Extra, brewed in Jamaica by the brewery that produces Red Stripe. We found it at CTI. It is most akin to the Guinness Foreign Extra that is newly available in the US, notably different than Guinness Draught which is more commonly seen in the US. There is also a Jamaican brand called Dragon Stout, from the same brewery. Dragon was not available at CTI, but you might look for it if the bus makes a stop on the way from the airport, or if you go into Ocho Rios. It is worth a try if you like stouts.
