COESPACE, an event venue in downtown Bangor, hosted the event.
Greendrinks, unsurprisingly, works to make Bangor greener. They've given out more than $30,000 in grants, for things like community gardens and bike racks.
They get that money through events like Tuesday night's, where they were selling beer from Two Feet Brewing and Geaghan's.
"There's no reason we can't have a lot of fun while raising awareness and money for great causes," said Greg Edwards, the treasurer for Bangor Greendrinks. "We're trying to make Bangor more liveable and sustainable."
Greendrinks also works with organizations they believe are making Bangor a better place. And Tuesday's event gave people a chance to learn more about them.
"I would like to just see more people moving here," said Andrea Irwin, the executive director for Mabel Wadsworth Center, one of the nonprofits featured. "I think it's really exciting to see that we're becoming a more diverse, progressive community. Greendrinks has done a lot to promote that."
Mabel Wadsworth Center is a women's health clinic in Bangor that works to provide reproductive healthcare and cancer screenings.
Also there were representatives from Partners for Peace, which is the region's domestic violence resource center. They were trying to reach a different audience and get more volunteers.
"The focus here has historically and traditionally been on environmental activism," said Saul Allen, a resource developer for Partners for Peace, "and we want to look at the social dimensions and how that's overlapped with some common interests and common causes."
"The work that they both do I respect so much, and think now more than ever we need to be working for women's rights," said Clare Davitt, who serves on the Bangor City Council. She was there not as a councilor, but because she supports Greendrinks's mission, and that of the nonprofits there.
Councilor Davitt commented on the event bringing together different parts of the community.
"I mean I'm a reference librarian as well, so again I think having the crossing over of information...I think it's an amazing way to spread information."
Bangor Greendrinks has events every second Tuesday of the month.
