Cold haze?
I've recently cranked up my fridge to the max setting to get better
cold stabilization results and - apart from frozen veggies - this resulted in some of my bottled whites developing a haze. This is what I've observed: - the haze is temporary, it goes away when the wine comes back to higher temperature in the glass; - the same wines went through cold stabilization before although under a lower fridge setting (set to min cooling); - the same wines are clear in the fridge at the min setting; - commercial and kit whites are clear under any setting. Anybody has an idea what's going on? My first guess was a protein haze, but I am under the impression that that one develops when the wine is heated and not cooled. The fridge temp is between 28-30F at the max setting. Thx, Pp |

I have a similar problem. I have three carbouys of Sauvignon Blanc
from fresh juice. I fermented pretty cold and added lysozyme after fermentation to arrest MLF. I fined with benonite, kieselsohl and isinglass and finally with spakalloid. The wine is pretty clear. I put one carbouy in a cooler at around 28 degree for two weeks. It appears to have dropped some crystals (although I'm not sure) but is is really hazy! Probably to hazy to filter. Is this a lysozyme phenomenon? I don't know if I should cold stabilize my other carbouys.

Most refrigerators are set to temps higher than 33 degrees so your wine shouldn't show very much tartrate crystals when they are chilled for serving. But, cold stabilizing at 33 degrees _may_ take several weeks. -- Lum Del Mar, California, USA |

But, > cold stabilizing at 33 degrees _may_ take several weeks. This is a very important issue for me as I am looking around for used front door freezer. Due to recent surgeries I can not use a top loading freezer. My older son put a 5 gallon carboy outside for me. Here in Baltimore (pronounced: Ball-a-mer - The City that Slurs) the temperature was 5F (-15C) and he didn't come home for four days. I couldn't carry it back in, but I went outside every day rotated the carboy enough to get circulation. It did stop the fermentation and I used rotgut vodka in the airlock so that had no chance of freezing. Now I am a Mead guy and want to use it to kill off fermentation. I had an experience with some Paul Masson wines several years. After a convention, I took several gallons home with me to store for later organization meetings. It was January in Chicago and I left them in the trunk of my car from Sunday evening to Tuesday afternoon. Night temperatures were -10 F. That's called a warm winter in Chicago. They froze and unthawed they had a significantly different taste. I am not a Wine guy, but the difference was obvious. Now 26F = -3.67C. Am I paranoid or is that low enough to freeze if left there for a week. Dick |

Where you cold stabilize it, as you pointed out above, is up to you. There's a great paper by, I think, Fritz Neradt and someone else about seeding to achieve cold stabilization that makes this point really nicely. I can't remember where I originally read that formula, though. It definitely wasn't from a peer-reviewed journal kinda thing. More like "here's how to make wine at home!" kinda thing.

But, I do know hazes are more likely with a rapid cool-down with no crystals in the container. So, I would get a small container of "cream of tartar" at the grocery store. Add a couple tablespoons of crystals to each carboy and try cooling the wine again. Good luck, -- Lum Del Mar, California, USA |
