La Rei Natura feels designed to make the Langhe speak in a quieter, greener voice. Michelangelo Mammoliti's cooking draws on gardens, herbs, vegetables, mushrooms, Piedmontese ingredients and a deep fascination with the natural world around Serralunga d'Alba. The luxury is real, but it is filtered through earth, leaves and memory rather than heavy opulence. A meal here is less about reproducing Piedmontese tradition than listening to it closely, then answering in a contemporary language of perfume and precision.
