I think you can make great beer in plastic buckets. The only thing is making sure the spigots (if equipped) are clean, clean, clean but that can be said of any fermentation vessel.
I used buckets for years and still find them a great alternative when all my conicals are full. Even better than buckets are the Genesis fermenters from Brewcraft.
I’ve had good luck with the Chapman Stainless fermenters. Not conical, just a stainless bucket with a much better seal, easier lid retention, easier to clean. Pretty good price point, esp. when occasionally on sale.
I have two 15 gallon Chapman SS fermenters. They work great and have lasted more than a decade. Easy to clean and you can eliminate beerstone with a dairy acid wash soaking. The only drawback is they are not pressurizable…but they replaced a broken lid clamp for free when I allowed a bit too much pressure to form in mine!
We have 3 Delta Systems Conical SS fermenters (8 gal), and they are great. Also we have 3 Anvil 4 gallon SS fermenters.
Just looking for an inexpensive way to add another way to ferment.
Might go with a nice bucket, and a racking tube.
I am trying to get the cellar cleaned out so I can build a proper brewery and have been giving my wife grief about getting new stuff and not getting rid of old so I would be hypocritical to get these because I have plenty fermenters that work perfectly well.
