Sour beers may not be for everyone, but those who dig them can’t get enough of them. Those who don’t? Well, they should keep trying. It’s an acquired taste. On Saturday, City Tap House is hosting Sour Saturday from 1 to 4 p.m. Thirty bucks gets you in with a All-You-Can-Drink All-You-Can-Taste ticket. More than 20 tart brews will be offered on tap and in bottles. And you get to keep the Sour Saturday glass issued at the door as a keepsake.
