Caffè al Bicerin, a historic coffeehouse of Turin which traditionally serves bicerin
The word bicerin is Piedmontese for "small glass" and is a clear dialect version of Italianbicchierino (diminutive of bicchiere, "glass").
The beverage has been known since the 18th century and was also praised by Alexandre Dumas in 1852. It is believed to be based on the 17th century drink Bavareisa: the key distinction is that in a bicerin the three components are carefully layered in the glass rather than being mixed together.
Caffè al Bicerin, a historic coffeehouse of Turin, has been serving the drink in Turin's piazza della Consolata since the 18th century, right across from the Santuario della Consolata, and some authorities believe that the drink was invented there. Others believe that it originated around 1704 in Caffè Fiorio, which still stands on what is now via Po.
