Hop BroYokosuka's GRANDLINE BREWING is teaming up at Beer Bar Sai in Nagaoka, Niigata, on May 24, 2026. A TTO and POPUP held at the same time is pretty exciting, right?
MugiWhoa! I've heard of TTO, but is a tap takeover that big of a deal!
Hop BroIn short, it's a project where a brewery 'takes over' the taps for the event so you can enjoy as much of that brewery's beer as you want. That brewery from Yokosuka really knows how to get people involved.
MugiI see... but a communication brewery doesn't mean they brew while chatting, right?
Hop BroNot that far. It means connecting people and events to widen the ways to enjoy beer. Even their catchphrase feels like the best moment for a toast, and it has a great vibe.
MugiNice! What kind of place is Beer Bar Sai?
Hop BroIt's a hidden-gem beer bar in an alley in Nagaoka, about a five-minute walk from the Niigata Coffee Festival venue. What's more, the owner holds the Dumens Bier Sommelier qualification, so they're very serious about beer.
MugiWait, a qualification too!? And they mentioned Flash Light Brewing too, but is that another brewery?
Hop BroYes, it's the owner's phantom brewery. They brew without having their own brewery, which makes it a perfect fit for a collaboration like this.
MugiThat sounds fun...! The event name MORE GEEKS is intriguing too, and it makes me want to grab a few drinks in Nagaoka on May 24.
Hop BroRight? It's the kind of pairing that makes you want to savor the atmosphere of the event itself. GRANDLINE BREWING's experimental spirit and Sai's local character - this is the kind of thing that makes you want to go drink there.
GRANDLINE BREWING (Yokosuka, Kanagawa) is a brewery that actively develops collaborations and external events as a "communication brewery" that bridges the real and virtual worlds. On its official website, it also uses the slogan "Cheers, make that best moment even better!" and is expanding the ways people enjoy craft beer from Yokosuka as its starting point.
What was announced on Instagram this time was the ONE MORE BEER x GRANDLINE BREWING COLLABORATION TTO EVENT. The venue is Beer Bar Sai in Nagaoka, Niigata, and it will host a POPUP SHOP on Sunday, May 24, 2026, from 10:00 to 21:00. The post also says that a Tap Take Over will be held that day as a collaboration event with GRANDLINE BREWING, and the event name is "MORE GEEKS".
Beer Bar Sai is a hidden-gem beer bar tucked away in an alley in Nagaoka, about a five-minute walk from the Niigata Coffee Festival venue. It is run by the owner, who holds the international beer sommelier qualification "Dumens Bier Sommelier," and who is also active as a phantom brewery called Flash Light Brewing. At this event, the owner's background and GRANDLINE BREWING's worldview will overlap, making it a chance to experience craft beer from a different angle than usual.
This project, where the experimental spirit of the Yokosuka brewery and the local beer-bar culture of Nagaoka intersect, takes the form of a tap takeover and offers a chance to enjoy not just the beer itself, but the atmosphere of the place as well.
