Banger’s on Rainey Street takes its beer program seriously, offering more than 100 draft beers at all times. Having so many on tap means that Banger’s employees need to be well-versed on styles and tasting notes, so the bar requires them to learn a lot in preparation.

The Rainey Street bar with more than 100 taps is turning 3 years old — which means, of course, that all those taps are being devoted to some of the top-rated and rare beers out there in celebration of the milestone.

Plus, because Banger’s Sausage House & Beer Garden has to live up to the meaty side of its name, there will be four pigs cooked four different ways starting at 2 p.m. A sampling of all four will be $15. Live music will include the Boxcar Preachers, the Sour Bridges and the Cover Letter.

Details: 11 a.m. Saturday. Free. 79 Rainey St.
