It doesn't hurt to take gravity readings. I brewed an american wheat that is kegged and just a beer or two shy from the keg blowing. I have noticed that the wheat improved greatly now that it has been in the keg for about 6 weeks compared to when it was first tapped. I have heard that hefs are better young, but that isn't the case in my experience. Take readings and follow your process. Take notes of what works and doesn't. It may be awesome young to you, or you may find it needs aging like mine did.
