Is it okay to ferment apfelwein in the plastic gallon jugs the juice comes in? I'm thinking I can get some stoppers & airlocks to fit the mouth of the plastic bottle, and that should be good. I've seen pictures of ciders fermenting in plastic juice bottles on here, has anyone had any kind of issue with these? I'm thinking I can mix the juice & whatever extra ingredients into a pot / bucket, then siphon (or just funnel) the mix back into the bottles (with an extra for the extra volume). Is there any reason as to why this Wouldn't be okay...?
