For higher gravity/alcohol brews I usually expect to put a couple month's age on them in the bottle before drinking. In the bottle flavors meld, some will mute and others will come to the fore. In a higher gravity beer there are more of these, so it takes longer--how long, depends on the brew, and the temperature of storage.
"So you say you just brewed your first batch of beer. Welcome to the obsession." --me, to every first time brewer I ever meet.
