I have been wanting to get into kegging but space is a serious issue where I live. As such, I have no ferm chamber or keezer. I do have a beer fridge though. I have been looking at the small kegging systems that would accommodate my half batches and wondering if it realistic to think that I could fit a small CO2 tank in the fridge with a 2.5 gallon keg. I have seen some with picnic taps and smaller gas cartridges too but I am leery of going too small with the operation. Anyone have luck with these setups?
