I know the Mr Beer kits have directions, but I'm 98% sure that their advertising department wrote them. No beer is ready for bottling in one week. period. Leave it for three weeks then prime and bottle. Then wait one month before drinking. I know, I know people say all the time that they bottled sooner and drank sooner, but I promise you: It will taste great and you will be very proud of your brew if you follow accepted homebrew practices. Rush the hell out of the process (ie Mr Beer instructions) and you'll be dissapointed and won't be comfortable letting anyone else drink it.
