An r/oakland post this week described a "building for lease or sale" sign at 303 Castro Street, home to Line 51 Brewing's taproom in Oakland's Acorn Industrial neighborhood, with what appeared to be the brewery's Instagram account indicating an announcement was expected. The Dissent has not independently confirmed the sign or the Instagram exchange.

A post in the r/oakland community this week, titled "Looks like Line 51 is closing," described a "building for lease or sale" sign appearing at 303 Castro Street in Oakland's Acorn Industrial corridor — the address of Line 51 Brewing Company's taproom, The Terminal. The same post said a neighbor reached out via Instagram and received a reply from what appeared to be the brewery's account saying an official announcement was "probably coming Monday." The Dissent has not independently confirmed the presence of the sign or the authenticity of the Instagram exchange, and no official announcement had appeared on the brewery's website or social channels as of Friday.

What is verifiable is the property record. The building at 303 Castro Street is held by Hz/Castro Partners — a separate entity from the Loverns who operate the brewery — with an assessed value of $325,717 in the 2025–26 tax year. The terms of any lease between that owner and the brewery are not in the public record, but a building listed for sale tends to land upstream of a tenant's exit.

Line 51 Brewing is a family business, founded in 2012 by PT Lovern and Leti Lovern, both former teachers. In its early days, the couple hauled kegs by transit: 15-gallon containers loaded at American Steel Studios, then ridden the 14 to the 51 and delivered to bars walkable from the line. "The idea was if you want it, you should ride the bus; you can walk to it," PT Lovern told SFGate at the time, as reprinted in a February 8, 2020 SFist piece on opening day. "You're not even going to use your keys." The Terminal itself soft-opened February 6, 2020 — a 7,500-square-foot warehouse anchored by a restored 1972 AC Transit bus in Line 51 livery, taps mounted on its side, after more than eighteen months of prior construction.

The 51A and 51B lines carry an estimated 19,000 passengers a day between Berkeley, Oakland, and Alameda. The brewery's website still lists a draft menu and event calendar. If the closure is confirmed, the Loverns will have run their taproom through a pandemic opening and six years at Castro Street before the building changed hands.
