Blackrocks-Marquette's Nano Brewery. At Blackrocks Brewery our mission is to have fun and brew great beer that challenges conventional norms. We offer you a wide variety of beers and rotate them regularly. The Blackrocks experience is: local, unique and diverse. Some say we are limited by our small size. We look at it a little differently, located in an old four square house, the brewery and tasting room compliment the small nature of our operation. The setting lends a neighborhood feel and harkens back to a traditional public house where people can meet and play chess or debate politics. Blackrocks doesn't serve food, but you will not go hungry here. Food can be ordered and delivered from several great local restaurants.
