I alway pour about 2 ounces out, then continue the pour in a clean cold water rinsed glass. I have everything from Kegconnection, and my keezer sits outside. I pour the first 2 ounces out cuz to cool the lines and tap. Do you suspect your lines are warmer than the beer? When you get a glass of foam, try pouring another right after. If it seems better, then its probably your lines being too warm. If not then either your beer is still overcarbed, or you serving pressure is still to high.
