A really young wine (released in the last year or so) may be a little bit too tannic and even harsh to the taste. By decanting it, you’ll aerate the wine and soften it up and it will become more enjoyable. Older bottles of wine, say 8 to 10 years old, are almost always decanted, because the tannic acids or tannins in the wine most likely have precipitated out into sediments — the fine, silty even grainy, particles you’ll find at the bottom of the wine. Decanting rids the wine of those sediments. In this video, Tim Gaiser, a nationally renowned wine expert and master sommelier, shows the proper method for decanting your favorite wine.A really young wine (released in the last year or so) may be a little bit too tannic and even harsh to the taste.
