Plastic vs Glass Carboy II, The Revenge
A couple weeks ago I posted about my issue with plastic carboys. As it turned out there are a lot of people who firmly believe that plastic is just as good if not better. I received a ton of comments and suggestions of how to treat the plastic carboys. Believe it or not I actually listened to and tried out. Here are my new thoughts on Plastic Carboys:
- Cleaning them is a synch with a 1/2 scoop of oxy clean and a 24 hours soak. I had no problem with the 3 or 4 batches I’ve brewed using the plastic carboys in the last couple of weeks
- The light weight and “Non-breakable” carboy is very easy to work with.
- The 6 gallon size is no longer an issue. With a couple drops of fermcap, the krausen is kept in check.
- Had an issue lagering with the plastic deforming and sucking the star san from the air lock into the carboy.
- I’m Still not sure about long term fermentation, 6+ months in a carboy. Will the plastic allow oxygen to get into the beer?
My only real problem now I have with plastic is the longterm fermentation of strong beers and sours. Does the Plastic leach oxygen, does it stain, and will the bacteria embed itself into the plastic? Does anyone have any personal experience with this?
I think for me for me I have no problem doing 95% of my primary fermentation in plastic. For secondary I think I’m leaning more toward glass but wouldn’t have a problem using plastic if all my glass carboys were occupied. But for sours and longterm fermentation of strong beers, I’m going to stick to glass.
