According to a post published by Fukuhaku Brewery (Fukuoka), the "PROUST SAISON 4th batch" has been tapped. For this batch, the brewery made some changes to the production process, taking into account an issue in previous brews where the alcohol content did not come out as intended. It said it increased the transfer volume into the fermentation tank and also set the carbonation higher than before.

With this adjustment, the brewery explains that it has made the dry, brisk drinkability typical of a saison more pronounced, resulting in a "more drinkable PROUST SAISON." To gather feedback from drinkers, S-size servings are being offered free as tastings for the time being, limited to one cup per person per day. The exact period is not specified, but the post says it is planned to run through the end of March.

First-time visitors are also welcome, making this an easy entry point not only for longtime fans but also for people who want to try a saison for the first time. Fukuhaku Brewery is based in Miyawaka, Fukuoka Prefecture, and operates mainly on weekends and holidays. It appears to continue refining the taste batch by batch while building up a taproom experience rooted in the local community. This 4th batch is notable not only for the recipe itself but also for the way the process was designed to fine-tune the drinking experience. Saison fans will likely find it worth checking how it differs from the previous batch.
