What a bummer! My gear is infected again. :cry: I had the same infection 3 years ago (http://www.brewersfriend.com/forum/viewtopic.php?f=3&t=904&p=5775&hilit=iodine#p5775). That time around the aroma smelled exactly like iodine. This time I wouldn't nessarily say, "iodine", but definitely very medicinal. The difference is probably only due to the different yeast I am now using (US-05 vs. WLP007). The taste though is exactly the same. It reminds me distinctly of chewing on hemlock bark (yes, I have done it, so yes I know exactly what it tastes like ), very bitter and "tanniny". The thing that is bugging me (besides having to buy new buckets again), is that I have no idea what type of infection I am dealing with. I am guessing wild yeast, but don't really know. The aroma and flavor definitely mellow after a few weeks in the bottle, but never really completely go away. Anyone else have any idea what might cause my beer to taste like hemlock bark?
