Poor horse. Haven't you beaten it enough already?
I use glass. I had 1 better bottle but it was easily scratched when cleaning so now it holds star-san.
I bet he still enjoys the beer he makes.
When I was first getting back into this hobby 6 years ago, I did a lot of reading. I was taking an extreme scientific approach to my brewing, taking readings of all the runnings, pre-boil, etc. Then I visited a friend on brewday who has many more years...
My false bottom doesnt seem to fit flush against the bottom of the cooler and at the end of the sparge I'll get a lot of husk material.
So I just put a metal strainer at the end of the hose and that catches 99.9% of it.
Mine is clear as can be, and I've k-meta/sorbated, and racked off into a new carboy.
But its still giving off bubbles so I'm leery of back-sweetening yet and assume its just leftover CO2?
I'm wondering if Wailing guitar and myself made the same mistake regarding your name. I didnt even consider your avatar pic as relating to the name. :P
I read better bottle and my first thought was scratches and that your one gallon of sanitizer isn't doing enough.
Do you have other fermenters, or the ability to purchase a "control" fermenter that is not a used better bottle?
