Dock18 Cocktail Lab

Dock18 is all about experimentation. Currently operating as a mobile cocktail experience, Dock18 organizes pop-up events throughout the Milwaukee area. We also offer cocktail classes for the budding home cocktail enthusiast and bartending services for both public and private events.


Bittercube was founded by Nicholas Kosevich and Ira Koplowitz in 2009. After successful stints bartending and managing at Town Talk Diner (Nick) in Minneapolis and The Violet Hour (Ira) in Chicago, they began developing Bittercube Bitters.

The first commercially available batches hit the market in July of 2010. Since then the business has grown to distribute bitters in nearly 30 states and abroad in Canada, Italy and Australia.
