I know what you mean. The longer you leave it (within reason of course) , the better it is. I bottled mine at the beginning of December and didn’t touch it until Christmas Day. The taste was pretty good then, but roll on another four weeks and it’s even nicer.
So brewed this kit mid December.
Was really tempted to tinker with it ( dry hop / water chemistry) but resisted and brewed straight out the box using RO water.
So bottled the whole batch , after two weeks the initial taste was decent , but couldn’t believe the difference after an extra week , the beer completely changed for the better was much smoother and the grapefruit was more prominent ..
So well pleased with the kit and will def do again.
Cheers
