mentions that plastic carboys with PET material are suitable for wine. Better Bottle is PET and that's what I've been using. However mine are all in use now and I noticed Wally Mart has a 5 gal plastic water cooler bottle for a very good price. It is code #3 -- and states that it is
Rigid PVC, Free of Bisphenol-A.
Would this be suitable for secondary fermentation? I'm thinking 1-2 months maximum when the BB gets freed up.
