I use glass carboys, better bottles, and buckets. Thought I may give one of these a try. They seem like a ported better bottle, but with a larger opening, more volume and about the same price.
i have not used one of those but i see no reason it should not work. it is made of hdpe as are plastic buckets. i actually made my lass christmas beer and stored 2 gallons in a new hdpe tank used for spraying bug spray etc. i naturally carbed it and then just used it like a keg. only that had to drink in one sitting due to pressurizing with air. i am going to try to rig a co2 to it next.
The space savings of fermenting in a single 60 L (15 gal) container would allow me to use just one fridge and still make 10 gal batches. I cannot fit two bucket fermenters in one fridge.
