Lagunitas Brewing Co.
These days owned by Heineken International, Lagunitas began as a craft brewery in Marin County in 1993 before moving to Petaluma in 1994. In addition to its large facility, the home of "hop-forward" IPAs operates a taproom, the Schwag Shop for gifts, and a beer garden that often bustles even midday. Guides leading the brewery tour, which includes a beer flight, provide an irreverent version of the company's rise to international acclaim.
