Hyper Decanting means putting wine in a blender for a spin or using a stick blender. Yes it's kind of crazy but yes it works to get rid of harsh tannins.
I have done it a few times with cheap young wines like a Cabernet Sauvignon or a Syrah but I have never done it on any wine I paid $20 and up.
I say do a little research on hyper decanting and give it a try!
