Beer on Tap


At diagonal, a beer pub in Aonuma, Kofu, Nara Brewing's `STUDY IN ROUGE` has been opened. The post describes it as a raspberry fruit sour. Its profile is said to start with a sweet-tart aroma, followed by a gentle vanilla note, while keeping the sweetness restrained. That makes it a beer where the fruit character and acidity should come through clearly.

Flavor Profile


What stands out is the balance. Raspberry leads the aroma, but the beer is not framed as a sugary fruit beer. Instead, the sour character gives it a clean edge, and the soft vanilla note adds a rounded finish. The result sounds layered rather than flashy, which should appeal to drinkers who like to follow how a beer changes as it opens up in the glass.
