You are looking for a yeasty, light beer taste. No bad tastes: acid, banana, band-aids, etc. It's not gonna taste like a proper pale-ale or whatever. "Light, somewhat malty beer" would be a good description of good yeast.
Gas is actually easy to scorch or caramelize the sugars/malt, especially with a starter if you don't keep everything moving and some malt contact the flame it can scorch it pretty quick. Good news is that carbonation is pretty dense and will drop out of solution fairly quickly. Just make sure to leave it behind and start over, you should be fine.
Life's too short to drink diet beer.
