Out of Office Brewing is a contemporary microbrewery and taproom situated on the second floor of the Ulster Sports Club in Belfast's Cathedral Quarter. Established in 2021, it offers a modern contrast to the retro music venue below, serving a diverse range of in-house craft beers, including popular options like the NSFW NEIPA and Pencil Pusher Session IPA. The taproom operates from Thursday to Saturday, featuring DJs, live music, and Detroit-style pizza slices. Visitors can also participate in brewery tours led by resident brewer Katie McBarron, providing insights into the brewing process and tastings of their beer selection. In 2023, the brewery launched a canned beer range and initiated the 'Cans for Cans' charity drive, supporting local homelessness services.
