Longmont-based Oskar Blues is opening its new event space, Oak Room, this weekend in a Mardi-Gras themed party open to the public The 4,275-square-foot space is adjacent to Oskar Blues’ barrel-aging room and, in fact, came about because of the need to store the brewery’s growing collection of maturing beers. “Our barrel aging program was really picking up, and we needed space for that,” said Chad Melis, marketing director for Oskar Blues.
