Here’s a myth I’ve wanted to debunk for a while now:
“Wine should be stored upside down or on its side.”

Why it’s wrong:
There’s actually enough humidity in the bottle to keep the cork from drying and cracking.
People’ve actually done scientific studies on this.

How the myth gets promoted:
It comes down to packaging.   Wineries using automated bottling lines find it faster to grab the bottles by the neck and put them in the box.  Thereby having to tape the neck side.  As it is easier to open the boxes from the other side, the taped side goes down.  Box manufacturers expect this and print boxes accordingly.    Wineries buy into the myth, because the system is designed for it.   The other main reason is that wine is often stored on it’s side in wine racks.  This isn’t because it has to be; it’s because its the cheapest way to store wine and have access.

Why you should care:
Bottles stored upside down leave all of their sediment in the neck.  While this may make for pretty dark ended corks, it also means some of that sediment comes out every time you pour.  The point of the punt in the bottom of the bottle is to help settle the solids out so you don’t drink them.  The irony is that you’ll often see an expensive bottle with a very large punt stored upside down, making it solely a marketing tactic.

If you store your wine on its side in a rack, make sure to keep it upright for a while before drinking it.

Good wine is often unfiltered and settles out.  That doesn’t mean you have to drink grit.   Just enjoy the wine.
