So after having a wonderful creamy guinness in a pub last night, I have decided to buy a nitrogen set up for one of the taps on my kegerator. I am still a new extract brewer and have not brewed a stout or porter yet. I was wondering if anyone had a good extract recipe or kit that they have made that they could recommend. Also i have heard for stouts and porters a long secondary is important. How long do most people keep those in secondary? Thanks, T
