The result of the beer that the one link pointed too was dismal. It still tastes like band aids, although it did mellow out a tad. I know in that case it wasnt the bottles since i could smell/taste it as i was bottling.
Was it the first time you used the IC. I just bought one and he told me to wash it thoroughly before using the first time or else it will impart a metallic taste.
Side note - I always rinse bottles right after use and then just need to sanitize them. I also never drink from the bottles and always pour the tasty yeast into my glass. A quick rinse and shake and there is no debris in the bottom.
