I've been having problems with the head retention on my beers that I force carbonate. Pouring from Keg or bottle, they look okay at first, but you can hear them fizz, which results in very little head after 30 seconds.
Now, everyone will problem say this is over-carbonation, but I don't think that's it. I've got my temp at 36 and PSI around 12 which should be about right.
So the last keg I put on tap was a Belgian Saison, which I KEG CONDITIONED with priming sugar. After 2 weeks of conditioning and chilling the keg, I poured a perfect pint of beer with great head, perfect carbonation, and no fizzing sound. I left the keg hooked up to CO2 overnight, and the next day poured another pint. It was fizzy just like the force carbonated beers and didn't taste quite the same as the day before. The nice fine bubbles I had were gone and head retention lasts about 20 seconds.
Again, I don't think this is an over-carbonation issue.
What is going on??!!
