Why does draft beer and bottled beer taste different?

Gladys Worthing: very simple.....draft beer has carbonation from the kegs. that is why draft beer rocks!!!!

Rosalva Steinmann: Same reason fountain soda and bottled soda taste different. Draft beer is on tap, and is effected by that process.

Joaquin Dronko: This is actually a pretty common sentiment. I can't stand some beer bottled, but will drink it from the tap without complaint. I believe kegs and bottled beers are preserved differently similar to how bottled soda vs fountain soda are.
