Even though I think Kingston is a blight on the human experience, if you can arrange to visit a Blue Mountain coffee plantation, by all means do so. The coffee grown in the mountains behind Kingston is some of the best in the world, and is almost beyond doubt the most expensive in the world. To be designated Blue Mountain, it must be grown above the 2,000-foot level.
The price for the coffee came about in an interesting manner. The industry was almost demolished by a hurricane in the 1950s, but the Japanese, who were just coming into their own, made a deal with the Jamaican coffee cooperative. In exchange for a gift of cash to get the industry going again, the Japanese would get the first right of refusal on each Jamaican coffee bean crop, and the Jamaicans could set the price. It looked like a win-win situation to the Jamaicans, and they made the deal.
It has indeed been a win-win deal and the Japanese buy almost the entire crop every year, but release enough onto the world market for people to get a sampling of the coffee. Thus, when you visit Jamaica and see the Blue Mountain coffee selling for US$30 a pound, you will know why it is so expensive. It is good, make no mistake about it, but probably not that good. The laws of supply and demand at work.
