FreeWheel ESB made with kveik yeast from Norway. This is a traditional centuries old yeast strain that until recently was not available outside of Norwegian farms. The yeast was nearly lost because even the commercial brewers in Norway didn’t use it. There are several types of kveik. Unclear which one this is. Kveik is unique among beer yeasts in how it ferments and the flavors it produces. The downside to the FreeWheel is that it is not the traditional farmhouse beer made with this yeast. This is at Mikkeller Bar in San Francisco.
