I put 3 carboys of Chilean Merlot in my garage about the first of the month. The temp was pretty much in mid 30's sometimes lower. Yesterday i went out to rack and move back in. When i did the first one there were no crystals, however, there was a thin layer of what i call "muck" at the bottom. I found that strange since the wine is about 8 months old and was pretty clear. Could that "muck" have settled due to the cold and/or could that actually be tartaric acid? I decided to leave it out there another week or 2. When i cold stabled my California Merlot i did get some nice crystals that settled.
