Best instant coffee bar none is "Jamaica Mountain Peak" packaged in Jamaica - home of the famous Blue Mountain Coffee whose beans sell at about $60.00/lb at most specialty coffee stores.
Though mostly available on the island the instant can now be found in many supermarkets in area of south Florida with a significant Jamaican population.
Though not made entirely for the highly sought after Blue Mountain (whose next 10 years production has been 80% bought up by Japanese brokers) its in the opinion of many far superior to anything out of Colombia or elsewhere.
