I would classify myself as an impatient person, but there are certain things in the food and drink space that I know require patience: waiting for dough to rise, allowing meat to marinate, and—especially—letting wine breathe.
Red wines, especially younger ones, often need to aerate after they've been opened. This is so that the oxygen in the air can help break down the tannins and sulfur compounds that live in the wine. This aeration helps soften the harsh flavors you may encounter if you don’t let this process take place.
