At the beer pub beer_sakaba_sai in Sakanoue-cho, Nagaoka City, Flash Light Brewing's guest beer "Flash Light Ginger Cookie (Spice Sour Ale)" is on tap. In an Instagram post (January 26, 2026 at 11:28), it was announced that this beer had already sold out at another location and was still being served at beer_sakaba_sai.

This beer is based on the recipe for "Flash Light Ginger Ale," first brewed at T.Y HARBOR Brewery on July 3, 2025, with cinnamon added and reworked into a single beer. It is described as layering the refreshing spice character of ginger, the tartness of a sour ale, and the soft sweetness of malt into a well-balanced beer that is easy to keep drinking. Specs are ABV 6.8% / IBU 17.3.

The key point is the cinnamon aroma that emerges as the temperature changes. Because its impression shifts little by little in the glass, it is the kind of beer whose character you can follow from the first sip to the finish. There is no can or bottle release; it is basically draft-only. It is a beer that is highly worth drinking on site.
