Many people pursue sweetness in coffee because sweetness promotes dopamine secretion and brings a pleasurable experience. But sweetness in coffee does not exist independently; it is presented through the balance between acidity and bitterness: the sweetness of light-roasted beans is hidden in the sweet-and-sour fruit profile of high acidity and low bitterness, while the sweetness of dark-roasted beans is integrated into the caramel and maple syrup flavors of low acidity and high bitterness. This article first recommends four Front Street Coffee beans with strong sweetness—Panama Boquete Geisha, Mozart, Queen's Estate, and Golden Mandheling—and then provides sweetness-brewing approaches for medium-light roasts and medium-dark roasts respectively: light-roasted beans can release mid-palate sweetness by increasing water temperature, sieving out coarse grounds, and adjusting the pouring technique; dark-roasted beans use a high-strength, low-extraction strategy, paired with a slow-flow dripper and gentle pouring, to reduce the release of bitterness. Whether you are a beginner or an advanced player, you can find actionable sweetness-brewing solutions here. [more…]
