There are particles (sediment, cork?) floating in wine that we have had about 15 yrs. Do you think it is still good to drink if we use a sieve to strain it?
Answer From Expert Roger Bohmrich MW
In principle, sediment in wine is a natural by-product of bottle maturation, depending on the wine and its age. I could not comment on the likely condition or drinkability without knowing the name and vintage of the wine you have, and how it has been stored.
You can try standing the bottle upright for a day, and then carefully and slowly decanting the wine in a bright light, stopping when you begin to see the first trace of sediment darkening the wine. If there' s a great deal of sediment, you can let it stand further after the initial decanting and decant a second time through a few layers of folded cheesecloth, or use a decanting funnel with a screen.
