Over the last twenty years, his collection has grown to over four hundred pieces, some of which are true rarities, valuable coffee makers from all over the world. They were produced in different periods between the first half of the 19th century and the 1960s.
In terms of historical completeness as regards the chronological order of the examples and systems he has gathered together, his collection should be considered among the most important and best qualified in the world. As an expert, he has written several papers and essays about the history of domestic coffee makers for both Italian (Antiquariato, Il Curioso, Cose Antiche) and European (the French Planet Coffee, the Polish Weranda) magazines.
