The Porthole is a simple, beautiful infusion vessel designed by Martin Kastner. 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.
