Reacquainting ourselves with how the Sigri Estate coffee from Papua New Guinea performs through the fabulous cona coffee maker. Does the roast profile need a small tweak? We like to try our coffee on a revolving basis as they do taste different on different days, and even at different times on the same day. The roast profile also needs adjustment as the green bean ages; the acidity flattens, and so the roast can be eased off in response.
