I was referring to this test:The beer was sitting in the line since the last time I tested. The second pour is the "clean" pour that wasn't sitting in the line. So I'm not sure what fast successive pours you're referring to. There's the beer in the line pour, and the beer that was in the keg not sitting in the line that followed. As mentioned, when I took the sample last test the beer in the line had a ton of yeast from a few days prior where I shook up the kegs and had a glass. This time there was no yeast issue.
I have a bunch of friends coming over Monday and will test again with both the hefe and Wit.
