Green coffee beans are the starting point that determines the flavor of a cup of coffee. From color and luster to moisture content, every detail reveals the quality code of green beans; the terms "new crop," "current crop," "old crop," and "aged crop," named by harvest year, record how time shapes flavor. During transoceanic shipping, temperature and packaging methods also influence the fate of green beans—low-temperature containers, temperature-controlled storage, and vacuum aluminum foil bags are all effective means of extending good flavor. The ultimate preservation challenge points to a simple yet expensive answer: vacuum packaging followed by freezing. This article systematically organizes the complete knowledge of green beans from identification to storage, and includes practical advice from Front Street Coffee, taking you deeper into understanding this green seed.
