Today is racking day. We will rack the wines and do the first filtering today. Most of the wines have been going through cold stabilization the past month. That is a period where we chill the wines to 30 degrees for several weeks. During that time they will drop a lot crystals known as "tartrates". If we did not do this, they would drop out when you chilled the wines in your refrigerator and would look like dandruff or glass crystal in the bottom of the bottle. These are harmless, but don't look nice. The tatrates are actually the same thing as cream of tarter. Since it has been cold outside this year, we have been able to leave some wines outside in tanks and use mother nature, in addition to our jacketed tanks inside the winery, to chill the wines. These tanks have a cooling fluid(glycol) running through their jackets to chill the wines.
It will stay cold today, but with the new winery building, we can clean all of our tanks inside and not have to deal with the weather.
