Several weeks ago, I made the St. Patrick's Irish Stout Deluxe Kit in my LBK. However, after things began fermenting a couple of hours later, the entire contents began to leak and make a REAL mess. It was annoying having to clean everything up and throw everything out.
So, I thought I'd use a regular 5-gallon fermenting bucket with an airlock next time.
And, boy did this help!
The krausen rose to over the 3-gallon mark, but the bucket held everything. No mess!
I then racked the fermented brew off the yeast into my clean and sanitized LBK and used that as my bottling bucket.
It worked great!
So, now I just use my own fermenting bucket and the LBK as my bottling bucket with great success.
Anyone else out there with leaks or messes should give this method a try.
