Guide to Gelato in Bologna

This past June when my friend Morten brought up the idea of joining him on a two-and-a-half week vacation in Bologna the first thought that popped in my head (aside from, "Hell yeah, I'm going") was, "What's the greatest amount of gelato that I can consume without tearing a hole in my stomach?"
Don't worry—I stayed well below this level or else I'd be typing this from a hospital bed.
My gelato consumption averaged out to one gelateria a day during my vacation. Some days I ate no gelato (gasp!) while other days I ate it more than once. Here's a round up of the best Bolognan gelaterias I went to, culled from Slow Travel's recommendations.
