Hi all,
I just kegged my Mild a couple of days ago, and there is a powerful band-aid phenolic flavor. There are three conspicuous things I did differently this time, and I'm trying to figure out which was the most likely culprit.
First, I used PBW to clean the kegs and it is possible that I didn't rinse well enough. I wouldn't expect phenols from PBW, but is that possible?
Second, it was the second time I used a new plastic fermenter http://www.usplastic.com/catalog/item.aspx?itemid=23849
The first batch from this ferementer was very good, no off flavor, so I doubt the plastic is the culprit. I used PBW to clean it in a long soak.
Third, I diluted the wort at the end of the boil with 2 gallons of water, direct from a drinking water safe hose. I allowed it to come back to the boil for sanitation, but might have added some chlorine with the water.
I use Star-San, no chlorine sanitizers. The yeast was the second use on WLP023, yeast collected and washed from a previous batch, then stored in a boiled jar in the fridge for about a month.
The phenolic odor is considerable when I vent the keg. I am hoping it is volatile, and will escape if I vent it daily for a while. Otherwise, I'll have to throw out 10 gallons of what should have been good beer.
