More than seventy tasters have travelled around Italy to source the very best wines. The tastings - all blind - took place in consortiums and local chambers of commerce and were supported by experts in the field, sommeliers and trade buyers.

The guide is completely accessible, organised in a simple, clear and functional way. Sections are arranged by individual winery - name, address, number of hectares of vineyard, method of cultivation (conventional, organic, biodynamic or natural). Entries are descriptive, of history and geographical region; evaluating the wines by the celebrated method of Bicchieri, or glasses, ranging from one, to a maximum of Tre Bicchieri.

The guide also pays special attention to wineries that are eco-sensitive, awarding Tre Bicchieri Verdi to bottles that come from those with a particular regard for the environment.
