You added a lot of oxygen to your beer by using the spigot and not a bottling wand. Oxygen = Oxygenation, Oxygenation=Staling. Once your beer is carbonated (2 weeks) I would store it as cold as possible. You have shortened the shelf-life of your beer and may notice a cardboard flavor in a few months. This will depend a little on style and a lot on how good your pitching rate/fermentation were.
What did you brew?
