On April 9, T.T. Brewery announced "NEW Beer! Bitter Sour!" on its news page. The update says its previous pale ale has been renewed, and true to its name, it has been crafted into a beer with a palate that brings out bitterness and acidity.

The article introduces the beer as "refreshing and easy to drink, with an excellent finish." It also says it pairs well with any dish, suggesting a brew designed for easy use as a meal-time drink. The fact that it is recommended even for craft beer beginners suggests the focus is less on strong individuality and more on drinkability and balance.

T.T. Brewery is a craft beer specialty shop based in Kawasaki City. It promotes its beers as one-of-a-kind brews made at its own factory, emphasizing beer you can drink only in Kawasaki. Alongside serving beer in its shop, it is also known for its commitment to quality control from brewing through serving, and this "Bitter Sour!" seems likely to be another potential new staple in that line.

This update, shared as news from the Kawasaki Cinetta Street location, is drawing attention as a suggestion for people looking for a pale ale that pairs easily with everyday meals. It is another locally rooted craft beer poured in T.T. Brewery's style.
