Missile Site Turned Taproom: Grist House Command Launches in Collier Township - The Beer Thrillers

Grist House Command occupies a Cold War-era Nike missile command center, PI-62, located on one of the highest points in Allegheny County. The bunker was built in 1957 and activated in 1960 to guard Pittsburgh from aerial threats. The facility has been converted into a taproom that blends aviation relics with hazy IPAs, dog-friendly patios, and community-focused brewing. Grand opening dates are September 6, 2025 (11 a.m.–10 p.m.) and September 7, 2025 (11 a.m.–8 p.m.). Co-owners Brian Eaton and Kyle Mientkiewicz acquired the property in 2018. The new location targets up to 30,000 barrels per year versus the current 2,500 capacity, following Grist House’s original Millvale site repurposed from a slaughterhouse in 2014.

You ever walk into a room that's heavy with history? That's the vibe when you step into Grist House Command, the newest spot from Grist House Craft Brewery, tucked inside what was once a Cold War-era Nike missile command center in Collier Township. This isn't your typical craft beer launch-it's a full-on story, a place where aviation relics meet hazy IPAs and dog-friendly patios.

Co-owner Brian Eaton, along with partner Kyle Mientkiewicz, took over the property back in 2018, and today their vision is turning one of Pittsburgh's hidden high-ground pieces into a landmark-beverage-style. While Grist House's Millvale location started life in a repurposed slaughterhouse back in 2014, this new command-post-style taproom is something else-a bold next chapter with 30,000-barrel potential per year, compared to the current 2,500.
