So I'm looking to ditch bottling (who can blame me?) for kegs, at least for the most part. My question is, if I want to brew a large quantity, say 20L+ but I want to take just a small 5L keg with me to some friends because they won't have the fridge space for something that big, what should I do? Do I get a larger keg and "decant" into a smaller one? If so do I then bother carbonating the first one or will that help preserve it, as I won't be able to refrigerate any large kegs (don't have the space or extra rooms or a garage/shed in a rented terraced house). What do you recommend?
