Jusan Brewery, which operates in the Juso area with craft beer at its core, highlighted "Black Bitterness KURO KUJU" in a guest beer post. The post category was `guest_beer`, and the publication time was 3:00 p.m. on March 20, 2026.

What stands out this time is the character implied by the name itself: "black" and "bitterness." The naming suggests a beer that combines the toasty aroma and dark impression derived from roasting with a firm, well-built bitterness, making it appealing to people who want a beer with substance, whether with food or on its own.

The beer is Kuro Kuju (KURO KUJU), and the brewery is BAK. In a beer pub like Jusan Brewery, which regularly rotates guest taps, the appeal is being able to catch a distinctive beer like this close to home. Because the flavor selection shifts depending on timing, it is worth checking the latest post before visiting.

The shop is located at 1-12-6 Jusohonmachi, Yodogawa-ku, Osaka City. It is easy to access from Hankyu Railway lines, making it convenient for everything from an after-work drink to a weekend pub crawl. If you are aiming for the guest beer, it is best to visit while the tap is still fresh and newly opened.
