Waltham-based general contracting and construction firm Vantage Builders Inc. has completed a renovation project for Boston Beer Co. at the brewer’s Jamaica Plain location.

The work includes a new tasting room, training rooms, barrel storage space, new offices and a mixed-blend laboratory for mixing and tasting beers. The project totals approximately 8,000 square feet in two buildings at 30 and 31 Germania St.

“We were pleased to work again with Boston Beer Co., one of the region’s most admired and well-known companies,” John Connor, principal at Vantage Builders, said in a statement.

The highlight of the project was the creation of the tasting room in Building H, which is used for visitors, tours and private functions. The room features a concrete-top bar, new light fixtures, custom millwork and windows, and a barn-door entrance. Vantage also built a training room with a dedicated bar. The new conference room features IdeaPaint, a whiteboard paint that transforms walls into a dry-erase writing surface that is ideal for idea sharing and brainstorming.

In the main building, Vantage renovated the mezzanine area, to add offices and a conference room with IdeaPaint. A new mixed-blend lab was created, where the essential work of beer mixing and tasting takes place. The project included significant building systems work at both locations, including HVAC, plumbing, ductwork and fire alarm/fire sprinkler systems.

The project team included Studio TROIKA architects, Bala Consulting Engineers and FMC project management.
