So I said I would give an L.A. listing of breweries.
I know you said LA to Rancho, but the South Bay is my home turf.
Here goes:
South Bay (El Segundo, Beach Cities, Torrance, etc.) = so dense, it's a bit overwhelming.

(Smog and Monkish are 1/4 mile from each other.)
King Harbor Brewing Company – 2907 182nd Street Redondo Beach, CA 90278-3922

I have had beers from 6 of those 7 breweries (Abigaile being the one I haven't) and they are all good.
Smog is my favorite by far, followed by Monkish. King Harbor and Absolution are newly opened (within the last 2 months). King Harbor is quality stuff. Absolution is just ok so far.
El Segundo are hop forward beers, but they do have a good stout.
Strand is all around good and the oldest of the South Bay Breweries.
Los Angeles:
Angel City Brewery - 216 S Alameda St, Los Angeles
Eagle Rock Brewery - 3065 Roswell St, Los Angeles
Golden Road Brewing - 5430 W San Fernando Rd, Los Angeles
Ohana Brewing Company - 1756 E 23rd St, Los Angeles (although their tasting room is in Alhambra)
Progress Brewing - 1822 Chico Ave., South El Monte (formally Federal Brewing) - probably had this beer almost as much as the South Bay stuff. My homebrew partner lives 5 minutes from here. Really, really good beer.
I've had beers from all 5 places. Good stuff. Ohana just won a silver in the World Beer Cup for Belgian-and French-style Ale category for its Ohana Saison Noir beer
If you divert down to Orange County:
The Bruery - 715 Dunn Way, Placentia
Noble Ale Works - 1621 S Sinclair St, Anaheim
Bootlegger's Brewery - 130 S Highland Ave, Fullerton
Tustin Brewing Company - 13011 Newport Avenue #100, Tustin
