Home Brew Mart is one of the catalysts that got me turned on to home beer brewing. This store is connected to the Ballast Point Brewing Company, which supplies San Diego with some of the finest micro brewed beer in the county. They are know for their Yellowtail Ale, and Marlin Porter. The ingredients they sell are the same ones they use to brew with. They carry Wyeast and White Labs pitchable liquid yeast, and Munton's extract if you do extract brewing. A good selection of grains (munich, crystal malt) and more. If you are a beginner they have tons of startup kits under $80 that can get you going.
