Rebrewed a terrific rye ipa, used my first crop of home grown cascade hops (@1 minute and flameout). Using my own hops was only recipe change. Beer was beautiful, clear amber and hoppy when I transferred from fermenter to keg. Three weeks on CO2 at 12 psi and I’ve got a cloudy viscous bitter mess. Strong alcohol aroma as well. Undrinkable!
I suspect it’s contaminated, but I’ve always been carefully to was and sanitize everything, keg (inside, outside, connections, gaskets) racking tube, etc. I’ve never had a contaminated batch in 17 years of brewing.
