Re: [Biohackers] Does Fermentation Station need a steady stream of beer bottles?

Hi all! How are you guys doing on collecting beer bottles - should we save all beer bottles generated at the Omni for you? Or just throw them in recycling? I'm planning to go buy some trash and recycling bins for Counter Culture Labs - just wondering whether I should buy a separate one just for beer bottles, so we can save them up for you. If you already have a container where you're collecting bottles, just let us know and we'll tell people to deposit bottles there (just don't expect them to clean the bottles first, because that ain't never going to happen...)
