I've tried quite a few Mandhelings, but aged Mandheling is a special existence that requires time to craft. It draws on the idea of Indian monsoon coffee: the green beans must be quietly aged in a ventilated, cool warehouse environment for 24 months, during which they are regularly turned to prevent mold and insect damage, consuming a great deal of labor. After this treatment, the beans' acidity is greatly reduced, their body is significantly improved, and their sweetness carries a honey aroma, with a flavor profile completely different from fresh beans. This time, Front Street Coffee used Sumatra Typica as the sample, roasting it medium-dark with 550g batch size in a Yangjia 800N roaster, and completed brewing with a KONO dripper at 88°C water temperature, ultimately presenting a cup that interweaves herbs and caramel.
