So I know the benefits of the head on a beer but should the head be the same for all beer? Will an IPA have the same type and amount of head as a lager? I have noticed that when I order a lager at a bar is seems to have a little head but it fades kinda fast. Is this something I should be trying to achieve if I brew a lager or should I be trying to get the best head I possibly can no matter what beer I brew?
