Even if the label on the coffee you buy says the same thing each time you but it, it may taste different. Flavor changes with each roast, and taste and quality of the coffee beans vary with each crop and shipment. Because Jamaica Blue Mountain coffee is scarce and expensive, there is a myth that it is the best coffee in the world. However, there are a lot of great coffees in the world at much lower prices. Kona coffee from Hawaii is expensive because of the labor costs involved.
Bean quality is high because the processing methods are meticulous.
However, the best Kona coffee never gets out of Hawaii because the best is saved for Hawaiians and Hawaiian tourists. Therefore, the Kona coffee that most people get throughout the world is a coffee with light body and flat taste. India's arabica coffee beans are often thought of by specialty coffee roasters as similar but inferior to those supplied from Sumatra. Arabica beans from this state are warehoused during the monsoon season which gives them a mellow, slightly spicy quality. Estate coffees from Papua New Guinea are carefully washed and come from the same stock that made Jamaican Blue Mountain coffee legendary.
