Question

What is `"decantation"`?

Answer 1

Do you mean `"decantation....."`?

Explanation:

Now we might decant a bottle of wine, by slowly and carefully pouring out the contents of the bottle such that the sediment is retained in the bottom of the bottle.

So watch your sommelier the next time he serves the Bordeaux.

`"Recantation"` is something else, and involves the denial of a previously held belief.
