Derailleur Brew Works, based in Osaka's Nishinari ward, has announced a new beer, `Luminous Black Light Ale`. On its product page, the brewery frames the release around three themes: Heisei gal, party night, and black-light fluorescence, presenting it as an energy-charged beer with a playful concept.

The brewery is rooted in Nishinari, an area of Osaka known for its from-morning drinking culture, and it has long emphasized unconventional beer making. That background shows up clearly in this release: the beer is presented not only as a beverage, but as a full experience that blends flavor, color, and drinking scene.

Key specs are as follows.

- Style: `Luminous Black Light Ale`
- ABV: 4%
- IBU: 21
- SRM: 9
- Ingredients: German malt, lemon juice, hops, cardamom, coloring (vitamin B2), carbonation
- Hops: East Kent Golding, Target
- Yeast: Lallemand - Windsor

According to the brewery, the beer is inspired by a Heisei-era gal aesthetic and built around energy and fluorescence. It features a lightly sweet body, a gentle cardamom aroma, a touch of lemon acidity, and a yellow-green glow under black light. With alcohol kept at 4%, the beer is designed to be easy to drink as well.

Sales are being handled through the official online shop. It is another example of Derailleur Brew Works' Nishinari-driven identity, combining visual novelty with a sessionable profile.
