For my latest batch, I made a Vienna lager that I have made a few times before, so I knew what flavor to expect. However, this was the first time I have purged my keg using via the method of filling with with StarSan then pushing it all out, then racking the beer into it via a closed transfer.
It tasted and smelled fine when I sampled it from the fermentor, but a week later when I took a pull from the keg it was drastically different. Gone was the nice malt aroma and in its place was an aroma that I can best describe as 'chemical/plastic' and slightly reminiscent of StarSan. The beer also has a bitter finish, but not in a good crisp way that you'd expect from a lager. It's more of a lingering bitterness with a slight harshness to it.
Somehow from the fermentor to keg, I screwed up but not sure how. I'm thinking either some StarSan got left behind or my keg or tubing wasn't properly sanitized and some bugs got in for the ride. Anyone else experienced something like this before?
