Nutty

What Makes Coffee Taste Nutty Nutty notes in coffee — hazelnut, walnut, almond, peanut — come from pyrazines produced during Maillard browning. The same reaction that browns roasted nuts browns roasted coffee beans. At medium roast, the browning produces light, clean nut notes alongside caramel. At medium-dark, the nut notes shift toward walnut and take on a slight bitterness. Brazilian and lower-altitude Latin American origins are most predisposed to nut notes. The beans' lower inherent acidity allows the nut character to read clearly without competition from bright acids. Colombian medium roasts often deliver caramel and mild nut alongside each other. Hazelnut vs. Walnut vs. Mild Nut Hazelnut: the lightest and sweetest nut note. Associated with mild acidity and creamy body — Lavazza Super Crema carries hazelnut clearly as part of its creamy, low-acid espresso profile. It reads as sweet and smooth. Walnut: slightly more bitter and astringent than hazelnut. Appears at medium-dark development. Intelligentsia Black Cat Espresso includes walnut as part of its dark-chocolate-and-crema profile. General nutty / nuts: a mild, background nut impression without a specific nut character. Caribou Blend carries this alongside caramel and light cocoa.
