My first brew was a porter and was drinkable after being in bottles for 2 weeks but unbelievably better after 4. I have 24 bottles left and they will not be touched until they've been in bottles 6 weeks.
Lesson learned. Even though I was repeatedly told on this site to leave them at least 4 weeks, I drank half the batch in various states of mediocrity. If I want another porter during the next two weeks, I'll pick up a sixer of Edmund Fitz at the corner store.
EDIT: except #25, which is sitting in the fridge. That one might not survive tonight. It's already in the fridge...it's begging for it.
