Mr. Pietro's old recipe book, which he created starting in the Twenties and kept continuously updated, contains ancient recipes for fine infusions and delicate liquors. The recipes relate the entire experience and enthusiasm of the man who understood how to identify, dose and mix up ingredients to create fine and exclusive formulas. Even today, that recipe book is a source for Marcati's production, which has succeeded in maintaining intact its character of craft originality, combined with research and experimentation.
