My question is this. How long can you keep a beer in a plastic fermenter before oxidation becomes an issue? I've left an RIS in the primary(plastic) for a month before, but then again a little oxidation seems somewhat common on those styles after you age them.
3 weeks? 4 weeks? 5 weeks? I always hear about oxidation in plastic buckets but I never hear about how long it actually takes to develop.
My next batch of pils I may do a side by side comparison using a 2 week primary in plastic for both and then a 3-4 week lager in a glass carboy and plastic bucket.
If its already been done please let me know the results.
