I purchased a 6.5-gallon HDPE bucket to use as a primary fermenter. I have not used a bucket for primary fermentation since my third batch. However, when I specified my requirements for a fermentation vessel, the lowly plastic bucket was the only fermentation vessel that came close to meeting them. The most critical requirement is that I need to be able to carry my fermentation vessel from my garage down into my basement while using only one hand going down stairs. I am reaching an age where I need to use the handrail, especially on stairs with small treads. A plastic bucket also has the advantage of being able to carry it with a solid lid and then switch out to a drilled lid. This decision was not easy for me to make because I have always considered buckets to be on the bottom of the heap. I thought about using one of this no-chill cubes to transport wort down into my basement and then transferring to a little less ghetto fermentation vessel, but then I would have to clean and sanitize two containers.
