Tap Update

At diagonal in Aonuma, Kofu, Yamanashi, the guest beer lineup now includes Fireworks from Open Air Brewing. The post introduces it as an IPA and notes it as a newly opened keg.

According to the post, the beer uses Talus and Sabro, two hops chosen for their tropical aroma. That makes Fireworks an IPA built around hop character rather than heavy bitterness alone, and the brewery's caption positions it as a beer that suits the summer season.

diagonal is a beer pub in Kofu focused on craft beer, so guest taps like this one are part of the venue's appeal. A beer such as Fireworks adds a clear seasonal signal to the tap list: aromatic, hop-forward, and easy to connect with when you want something flavorful but still refreshing.

For drinkers visiting diagonal, Fireworks is the kind of beer that invites a slower pour and a closer look at the aroma. If you enjoy IPAs with a tropical lean, this guest tap is one to note.
