The first keg of my Marzen/Ofest was fantastic. My cousin had an Oktoberfest party and I took a couple gallons. It was a big hit. So the first keg kicked pretty quickly after that. I put the second keg on and....ugh....WT...
It's tart, sour, odd off flavor, cloudy and doesn't hold carb well. Bummer. The second 5 gallons stayed in the fermenter about a month longer than the first but this doesn't taste like oxidation and the color is fine...maybe the bucket wasn't well sanitized... Now I'm annoyed...no more marzen...
