Oskar Blues Mama's Little Yella Pils is not an aggressive beer at all. It pours yellow, as advertised, with average head. The aroma is mild. There’s a little bit of a sweet lemon thing, but not a lot else. The flavor is really mild. Probably too delicate for my blunt palate. A little malt and a little tingle, and it’s gone. I didn't dislike it, but I can't say it really grabbed me, either.
