Just trying to get up to speed so I can help you figure it all out. And 6 minutes late!!! Ya beat me to it squirrelly!!
These two batches are my first batches in the kegerator. One was an American Wheat and the other is BM's centennial blonde, which I was really excited for. Brand new beer lines, sanitized equipment, etc.
Yes, I pressurized both cornys and let star san run through my lines and faucets for about 20 seconds each.
I replaced my first beer lines, which were about 5", with 10" lines to reduce foam. I made sure to sanitize everything again. With my kegerator temps at about 40, I carbonate at about 12 psi.
My first kegged beer has been in there for about a month and a half. Although the flavor seems more subtle now, it is still present. Not sure if the carbonation is helping mask the off flavor. My newest batch, BM's centennial, has only been in the keg for two weeks. And again, it has the off flavor of the other beer, but it's more noticeable. Now that I think about it, this flavor isn't present when racking to the keg. Actually, I don't think it was there for either of them, which makes me think even more it has something to do with the corny keg, dip tube, or beer lines. Even though I sanitized everything, I didn't take apart everything and put it back together because I didn't know how.
I ferment all of my beers for a minimum of three weeks, check gravity a couple times, and then rack after about four weeks of fermentation. Airlock activity, if I recall correctly, probably stopped after 4 days or so.
One last thing, since I'm new to kegging, I'm not sure what the correct method is but I keep my beer lines connected to the keg at all times. So, I might have a beer one night, and then not have one for another week or so in this case. This means the same beer is in the line untouched the whole time. Tonight, I made sure to dump out a few ounces to account for any beer left in the lines for a while and that didn't fix it.
I appreciate everyone's help. If I can't figure out what my problem is, I might just try to sell all my kegging equipment and break even on what I bought. I'd rather just make beer that tastes great like my first two batches without having to worry about negative flavors during carbonation.
