- I’m not very strict about the 3 month deal. I probably do more like every 4-5 months and even skip altogether at times.
-I rack with a vacuum pump, which I think adds more control.
-Even if I siphon splash racked every 2-3 months I wouldn’t worry anyway. I welcome the o2 throughout the entire process. Open ferment/funneling the press wine into the vessels, splash racking etc. I try not to fear o2.
I have a little theory that may or may not be able to be scientifically proven. In simple terms I think early, routine, and controlled o2 exposure allows the wine to build up a tolerance sorta, and helps it mature at a faster rate. And a wine that’s been sheltered from o2 could have a more drastic change when exposed later on IMHO. (especially color)
I had the benefit of growing up with old style winemaking in my family (too much headspace, no so2, screw cap bottles, tons of o2 exposure etc) and somehow it never went bad. But usually was all gone before it hit the 2 yr mark.
