I was wondering which home brews tend to keep the longest ex. Ipa, Porters. I know that they are not neccesarily like wines but I know that some are able to retain their flavor longer. I was hoping to built up a small stockpile so I would always have some and possibly even different types. Currently I bottle everything I brew. I am getting ready to start kegging some and also was not sure if there is a difference in shelf life between the two.
