Pouring wine from the bottle into a decanter allows the liquid to oxidize, open up, and slip away from pesky sediment. Similarly, pouring your whiskey into a decanter will allow the spirit to interact with oxygen and make it easier for more nuanced aromas to bloom. Look for a decanter with a solid stopper and stable bottom to ensure your liquid will stay safe wherever you set it. Of course, always make sure that the bottle is “lead-free” as many lead crystal decanters still remain on the market.
