2 months is fine. Lots of people will leave their beer in a secondary fermentor longer than that. The only issue you'll have is that your beer might be oxidized and taste old because the cheapo plastic bucket fermentors generally aren't terribly air tight and are only good for the primary fermentation. If it was in a carboy or more airtight vessel, it would be perfect.

As for smell, it won't. I once forgot to clean out a fermentor after bottling and had it sit in a hot garage with about half a gallon of beer and the yeast cake for the better part of a year without odor.


Two months is not too much, if the temperature is not too hot.

Best scenario, you could be lucky and still have some water in the airlock. Beer might be fine.

Worst scenario, water has evaporated in the airlock. Beer has a great risk of contamination or spoilage.

As for the smell, it will depend on temperature as well. If the airlock is dry and the temperature rises, so will the smell. If you can send someone to get rid of it, you could also send someone to fill the airlock, giving you more time?
