Soap/Cleaner Taste at after Taste

If you have a spare keg, you might run use that to run some Beer Line Cleaner through your lines. Sanitizer is not a cleanser. It is possible that the soapy flavor is coming from the keg and not the lines, in which case I don't see a solution. That would mean either the keg had soap residue when you added the beer, or the beer developed a soapy off flavor.

 

Th soapy flavor could also be from the beer. Did you have a lot of trub going from the kettle to the fermenter?

 

If the soapy flavor is from trub (i.e. fatty acids converting to soap), I don't think there's a fix.

If it's from residual cleaners in your beer line or faucet, you could clean, rinse well, and re-sanitize. I use BLC to clean my lines/faucets. With BLC, you need a way to pump it through the lines and faucet...either from an extra keg (pushed by CO2) or a hand pump device.

If it's from residual cleaners in your serving keg, I think you are screwed for this batch.

 

Vikeman's well articulated thoughts vis a vis BLC, soap in the lines, soap in the keg, and soapy flavors derived from trub, are exactly what I was trying to say early this morning before I finished drinking my first cup of coffee.

In my brewhouse, I never use dishsoap on anything. I use oxyclean during a cleaning phase, followed by at least triple rinsing with hotwater. I don't want to start an argument, but acknowledge that PBW is probably better than oxyclean, but I haven't gone that route yet. However, I have recently started using BLC on my lines because there was a thread a few months back that expressed astonishment at how dirty lines can get. When I tried it, I didn't see crud coming out of my lines, but now that I have the stuff, I'll continue to use it, at least between batches. I do not have a handpump, so I put some in an empty keg and push it through with a little CO2.
