Jumo is fermented with Voss kveik, a strain of yeast isolated from the fermentation culture of a Norwegian farmhouse brewery. To add to Voss kveik’s distinctively orangey ester, we hopped Jumo with Mandarina Bavaria, and lightly augmented with some spices. And to add the acidity appropriate to citrus fruit, we lightly kettle soured the beer. The result is a tart, dry beer that is startlingly reminiscent of a mimosa.
