So far I’ve come up with the Eagle Rock Brewing Company that is available on Sundays only. The other searches I’ve tried give me hits regarding restaurant/bars that happen to brew their own but not an actual full-on brewery tour available.
Drive South. Stone Brewing.
Take the 405 freeway to the Roscoe exit. Go west 2 blocks.
On the right you will see Tommy’s. Go in order a cheeseburger and chili cheese fries.
Sit near the window, look across the street at the biggest damn brewery you are ever liable to see. More Bud than you can shake a stick at is made there every day.
No tours, but this place is huge.
I remember when you used to be able to tour the Annheuser-Busch brewery in Van Nuys. Don’t laugh. The tour was on a monorail that passed through the huge complex. It was pretty neat. That was also when they had the Busch Bird Sanctuary there.
Sadly, the park and monorail ride closed in 1979.
