Fermenting 11.5L batch in a Coopers 25L bucket?

[davidgrace]

I have a Coopers fermentation bucket that is like new. However, it can hold 25L and I only brew 11.5L batches. So, I want to ask what are the consequences of fermenting 11.5L batches in a 25L bucket?

None but you will soon run out of beer.

The only issue you might have would come from leaving it there for a really long time. The 2-3 weeks that it takes most beers to finish would be fine. I've brewed 2 gallon batches in a 5 gallon bucket with no problem.
