If you're curious about what exactly makes Portland the brewing capital of the country, it might be a good idea to sign up for a tour with the Portland Brew Bus. After gathering with your group in the lobby of DoubleTree by Hilton Hotel Portland, at 1.30p, you are taken on a four-hour journey of breweries like Widmer Brothers Brewing Company, The Old Lompoc, Bridgeport Brewery and Pyramid Brewing, and you get to sample many of their famous creations. If you don't wish to participate in the public tour, you can opt for a charter tour that will begin from a destination of your choosing.
