I posted on HBT a while back, but I hardly ever use an actual computer and the HBT app is not as effective as actually being on here. Recently have started taking my brewing to new levels as well as devotion. I started brewing back in August with a Northern Brewer deluxe kit and now I am trying to step up my game. I recently upgraded to three burners, built a mash tun, made a paddle, and ordered a keg system with fridge mount.I also bought the Beersmith software about a week ago and have been playing around with that. I have gone through about 4 or 5 different batches of homebrew since starting and I am obsessed! The keg is being shipped as we speak. I have never tried kegging before. I was wondering if anyone had some tips for a first timer? Also I was hoping to have someone share knowledge with me about only kegging a portion of my batch and bottling the rest? Can I only put say 3 gallons in a 5 gallon keg?
