Stores green coffee for months or years so acidity fades and flavor and body strengthen, as in Old Government Java.
Aged green coffee is held for extended periods, at some Javanese estates up to five years, in burlap sacks that are regularly aired, dusted and flipped. The beans turn light brown, and flavor gains strength while acidity is lost, with notes ranging from cedar to cinnamon or clove and often a thick, almost syrupy body. The category is known through Old Government, Old Brown and Old Java coffees. Ordinary green coffee, by contrast, tends to mute over months, with some coffees holding character for 14 to 16 months.
