You may know that Trademark Brewing is close to opening (or open now as of posting date). It is on my list of breweries to watch as Long Beach continues to grow apace.
Near them in the Washington neighborhood of Long Beach will reside the super small Hog Canyon Brewing. Founded by Larry Chavez, this nano is looking to open later this year, probably Q4 and start up with what will be by necessity a rotating set of beers.
Look for 1st Visit reviews of TM first and then Hog Canyon as I try to stay current with the scene to the south.
