I are also a homebrewer. I second 5280 Fermentation Society, as I am a member. A great group of guys and (gal). I also belong to the Keg Ran Out Club in Westminster.
The Keg Ran Out Club We meet the 3rd Thursday of the Month at Beer at Home in Westminster. Also a great group of guys and gals who are very knowledgable about brewing. I live in Whittier/Five Points and brew just about every other weekend. I would be great to have some group brew sessions. I love my zen time with my mash tun and kettle but geeking out with other lovers of craft beer is also a blast
