I just finished a kegerator build, complete with a custom thermostat so I can set the temperature to the degree. Now the question is: What temperature range is best for each beer style?
Play around with the temperature until you find what you like. I tend to leave my fridge around +45°F (or +7°C). I've found that gives me temperature I like best across styles.
Here's a general temperature guide for styles.
