Chicago designer Martin Kastner is the man responsible for one of the most coveted innovations in barware: The Porthole, a device that infuses a cocktail as you drink it. Kastner made the Porthole for Grant Achatz’s bar The Aviary, where some of his other Crucial Detail glassware designs are also on display, from the aroma-containing cloche, to the sling that holds a cocktail-filled ice sphere.

The Porthole is a simple, beautiful infusion vessel designed by Martin Kastner of Crucial Detail design studio. It can be used to create striking cocktails, oils, teas, dressings, lemonade, coffee, or any other type of cold infusion.

Since its debut in 2011, the Porthole has gained significant attention. Originally created as a custom piece for the bar chefs at The Aviary in Chicago, IL, it has been featured in dozens of magazines and blogs, including the cover of Food Arts magazine.
