The bicerin, native to Turin in Italy’s Piedmont region, has been served since the 18th century and is built from three ingredients: espresso, ganache in the form of thick hot chocolate, and frothed milk. They are never stirred together. The dense chocolate anchors the bottom, the hotter and lighter espresso floats on it, and airy milk sits on top, so each sip moves from cool milk to hot, bitter coffee to thick, sweet chocolate. The name comes from the dialect word for bicchierino, a small glass, because the clear vessel that shows off the layers became part of the drink’s identity.

Its historic home is Caffè Al Bicerin in Turin’s Piazza della Consolata, directly across from the Santuario della Consolata, where cold churchgoers could cross the square to warm their hands on a glass. That fixed location is why the drink stayed tied to one plaza instead of becoming a portable recipe. The episode then follows the name into a hazelnut chocolate liqueur and places the bicerin among Italy’s hyper-local coffee rules.

• The layered build is presented as a deliberate contrast with the modern mocha, which blends everything into one temperature and flavor.
• Serving a hot drink in thin glass trades the insulation of a mug for the view of the layers.
• The Vincenzi family distillery in Turin makes a Bicerin liqueur with chocolate and hazelnut.
• Turin is the birthplace of gianduja, a chocolate hazelnut paste described as an ancestor of modern spreads like Nutella.
• The marocchino, also from Piedmont, and Puglia’s espressino are related small-glass espresso drinks with their own builds.
