Faction Brewing

This brewery on the northern tip of Alameda Island is well-known for its hoppy beers. They pour the full suite of their brews, as many as 10 or 20 options, depending on the time of year. And everything is brewed on-site. It’s packed on the weekends, so go mid-week, or early Friday and get their daily flight option. I don't think they give tours, but if you have to use the bathroom, you literally have to walk through the brewery to get to it, so you can catch a glimpse of their set-up then. Also, this is one of the best places to catch the sun setting over San Francisco.
