Development History

One hot Seattle summer in 2014

During an unseasonably warm summer in 2014, when coffee drinkers were looking for a cold and refreshing alternative to hot coffee, nitro cold brew was just starting to appear on the market. One of True North's cafe clients wanted to start offering our coffee as nitro cold brew. After sampling all the available offerings on the market, which were all either flat or lacking flavor, John Hofius, owner of True North Coffee Roasters, took this as a challenge to create a system that would enhance our coffee's robust flavors in nitro cold brew form. He set to cracking the code to produce a head of persistently cascading micro-bubbles by hand building a prototype device to blend an exact ratio of delicious cold brew and effervescent nitrogen. 

True North’s nitro cold brew produced with this hand-made device was instantly in high demand and lauded by Seattle food critics. In May of 2015 True North’s nitro cold brew was featured in Zagat’s 30 Things To Eat and Drink in Seattle this Summer.

In the subsequent years, John worked with Amy and Michelle Martin-Tyler, and Kimball McKeehan to refine the original handmade prototype into the HeadMaster to address the gap in the market for consistent, creamy nitro coffee beverages.
