Torrance’s Smog City is expecting big crowds from noon to 8 p.m. Saturday for its “Rarest of the Rare” event with about 20 rarely seen and little known beers served at two bars.

Among the promised concoctions is a Weird Beer (a five grain Saison with spices), a Grape Ape IPA made with 500lbs of flame grapes, pressed on site, and a Bourbon Collective Evil, a 2011 collaboration with Julian Shrago of Beachwood BBQ.

And gourmet hot dogs will be served.
