Physicists have searched for Neutrinoless Double Beta Decay (0vββ) for about a half a century. Developed over the latest 20 years, the bolometric technique is today used by one of the most competitive experimentsin the field: CUORE, a ton-size detector aiming for a sensitivity of ∼1026 yr on 130Te 0vββ decay half-life. With the final step of its construction nearly completed, CUORE will start its operation by the end of the current year. Meanwhile, the first CUORE-like tower is operated at Laboratori Nazionali del Gran Sasso as an independent 0vββ experiment. Named CUORE-0, it represents the state of the art for large-mass, low-background, ultra-lowtemperature bolometer arrays. Besides being a competitive 0vββ decay search, it has validated the ultraclean assembly techniques and radiopurity of materials for the upcoming CUORE experiment.
