Freeze your unfinished wine - it works!

When a neighbor told me that rather than dumping unfinished wine, he freezes it, I was doubtful. In this rather extended video episode with the help of wine expert Mao Fujita (Mao Lecours), I examine whether this method of preserving wine actually works.

Here is the tartaric acid sediment (explained in the video) in red and white wine. While it may not look appealing, it is perfectly harmless and can easily be removed by decanting or careful pouring.
