I'm new to kegging and have hooked up my two most recent brews (a Fat Tire clone and a blonde ale). They both taste thin and watery, which wasn't the impression I got from them when I racked into the kegs. Is it that my carbonation is off (too low or too high)? Or is there a way to improve the mouthfeel now that it's kegged. I know dextrin can help during brewing, but it's a little late for that now. Thanks!
