Let's say hypothetically I brewed a 8.9% ABV bitter chocolate oatmeal stout and left it in the Carboy for 3 weeks and then bottled for 2. So it's been 5 weeks total since we brewed. My brother is saying we have to leave the beer in the bottles till November 25th before we start to drink them because he read for every percent above 5 you add two weeks time to the bottles and this would be playing it safe. What would the beer taste like if I opened it today?
