The 1118 will definitely wake it up, and yes the smell can really sting the nose if ya get in there real close...normal. Retread2 and Heavywalker make some good points. Yes aeration is good for the beginning of the ferment cuz the first few days the yeast need to multiply before they really go to work. I have started my batches with 1118, it took about 48 hrs to notice any real bubbles at all, but shortly after that it damn near blows the top off. I agree that a smaller container should be used for a small batch, simply because when fermentation takes off it takes longer for co2 to fill a large airspace, thus less bubbling at the airlock in the beginning. I believe this may cause impatient brewers to pop the lid off and look for foam, giving the nasties more chance to spoil your fun. That's just my personal opinion on that matter, no real scientific value.
