I brewed the Black ship Pirate Stout (10 gallons) all grain recipe from Randy Mosher's Radical Brewing which includes a late addition to the boil of crushed corriander seeds and allspice. I put the beer in the two primaries with a two large starters and it had some very vigorous fermentation for several days, racked it to my secondaries. All was fine up to here. In the secondaries I added more crushed corriander seeds and a week later the zest of an orange which I had soaking in vodka for a week. A day after the addition of the orange zest to the secondary I got a white sunstance which you see in the "Carboy right.jpg" pic attached. Followed by the growth of large white hollow spheres you can see in "Carboy left.jpg" pic attached. I have been trying to determine whether this batch has gone terribly wrong. If anyone can help that would be greatly appreciated.
P.S. The floating brown bits you see in the pictures are just the corriander seeds, it's the white part I'm worried about.
