Mixing It Up

I've heard of people having wine mixing parties where the participants create their own wine by mixing different varietals together. Tonight I mixed together two reds that I had been disappointed in individually. One was a little too acidic for me and the other was too fruity. I used about 2 to 1 acidic to sweet and the result was smooth and very pleasing. I don't know that I'd buy the same wines in order to make my mix again, but it gave me confidence to try again using other wines. The only problem with mixing wines is that I'll end up opening at least two bottles and then I'll have to drink it before it goes bad.
