I just finished kegging my third kegged brew (5th brew, but third in a keg) . I have a sanyo kegerator with 2 kegs in it already. One of the kegs in the fridge is down to about 1 gal probably, that should be done in a week or so? So, I have no space for this fresh keg. I just put some co2 in it to seal it and set it next to the kegerator - is that cool? Can I just let it sit for a couple weeks before I put it in the kegerator. Thanks.
