I've been brewing all grain for about a year now and have been having some issues with off flavors (astringency and harshness), especially in some of my darker beers. I run all of my water through a carbon filter from B3. I sent in a sample to Ward Labs, and it looks like my water is fairly good, though a few things are outside the target ranges.
I'm still trying to get a handle on what adjustments, if any, I need to make but I'd be grateful for any initial impressions on whether this profile could be a candidate for the astringency I've been having. If not, back to the drawing board! Much appreciated.
