Plastic-free home carbonation with 5lb tank?
I built a home carbonator many years ago with a 5lb tank, a gauge, some tubing, and a carbonator cap that fits onto standard threaded plastic bottles (like 1L soda bottles). I would fill them most of the way full, squeeze the extra air out, and then carbonate. The water turned out great and was the exact fizziness I like. I could do six bottles at a time and have them ready to go in the fridge.
I’ve grown concerned over the years with microplastics and I’d like to find a plastic-free option that will work with my carbonation rig. Any ideas?
