Clessidra Spirit Glass
Leonardo Borra's Clessidra Spirit Glass takes its name from the Italian word for hourglass, and the reference is precise. Two chambers, joined at a narrow waist, channel oxygen through the spirit as it moves between them, opening the aroma in a way a conventional glass simply cannot.
The form is deliberately unconventional. Where most barware retreats to familiar silhouettes, Borra experiments with geometry as a functional proposition. Each glass is handmade by Steroglass artisans, a Venice-area studio with deep roots in Italian glass craft, giving the object an irregularity that marks it as made rather than manufactured.

Frequently Asked Questions
How does the Clessidra's twin-chamber shape affect the spirit?
As liquid moves between the two chambers, it is exposed to increased surface area and airflow, which accelerates oxygenation. This process opens volatile aromatic compounds in the spirit, making both the nose and the palate more expressive than they would be in a standard glass.
Is the Clessidra Spirit Glass handmade?
Yes. Each piece is handmade by Steroglass, a studio rooted in the Italian glassblowing tradition. Minor variations in form are inherent to the process and distinguish each glass as an individual object.
Which spirits work best in the Clessidra glass?
The design was conceived for aromatic spirits where oxygenation has a meaningful effect, such as aged whisky, Scotch, grappa, Cognac, and barrel-aged rum. Spirits with more delicate profiles also benefit, though the effect is most pronounced with complex, aged expressions.
Who is designer Leonardo Borra?
Leonardo Borra is an Italian designer whose work often explores the intersection of everyday function and unexpected form. His collaboration with Steroglass applies that sensibility to barware, treating the drinking vessel as a site for genuine functional experimentation rather than surface decoration.
How should the Clessidra Spirit Glass be cleaned?
Because of its narrow waist and twin-chamber construction, hand washing is strongly recommended. The geometry makes standard dishwasher cleaning impractical, and the handmade glass benefits from careful handling to preserve its surface quality over time.
