Re: Beer or milk instead of water?
Beer has a bad habbit of bubbling up really bad, milk does the same but its not as bad. Its certainly not bad for the hookah just make sure you clean it. Also many people use milk. I agree that it gives it a cleaner taste, but I don't like the bubbles. Try using a small amount of Milk in a base of water, this cuts down on the bubbling.
People also say milk makes bigger clouds and takes away from taste, same for ice water... It's all about preference and experimenting.
