The white truffle (scientific name Tuber Magnatum Pico) also known as the white truffle of Alba, is undoubtedly the most valuable truffle variety both from an economic and gastronomic point of view. The gleba is white, with a marbled appearance, over time it takes on reddish spots on a gray background. The smell is intense with tones reminiscent of tetrahydrothiophene (used for the odorization of methane gas intended for domestic distribution). It grows underground at depths that can go from a few cm up to over a meter in clayey soils, often near watercourses.
